CATALOG 21807 – Volume XLV, No.7

ALMANDINE in OLIGOCLASE etc.- Micaville, Yamcey Co., North Carolina
A classic pegmatite assemblage, here as bright purple-red phenocrysts and crude ccrystals of almandine garnet scattered in albite (var. oligoclase), quartz and muscovite matrix. Old material originally purchased in 1956 from Gene Curtiss (1926-2012) and rarely seen on the market today. Generously sized specimens from about 5cm to 12cm across @ just 10.00, 25.00 and 45.00 each.

ANDREDINIITE (IMA 2014-049)- Sant Olga Tunnel, Mt. Arsiccio Mine Tuscany, Italy
This relatively NEW SPECIES is offered here from the type locality as tiny single silvery metallic flat crystalline masses without matrix. Formula: CuHgAg7Pb7Sb24S48 - monoclinic, IMA #2014-049, a new member of the lillianite group, Type locality, only two available @ 175.00 each. See our image on Mindat.org.

BARITE- Baia Sprie, Maramures, Romania
An old, classic locality for the species, here as tightly stacked transparent to translucent plates of barite completely comprising matrix, with some crystal aggregates forming balls to 2.5cm across. The specimen is ex-Czech National Museum and is accompanied by their label, overall size about 8x5cm @ 175.00. One larger, 11x5cm with 2.5cm crystals @ 395.00. Attractive, but only one of each.

CASSITERITE- Trevaunance Mi, St. Agnes, Cornwall, England
This ancient locality was once a major producer, particularly in the 1800s, now overgrown and inactive for many decades. Cassiterite occurs here as micro brown to black tetrahedral crystals and aggregates scattered in seams on a metamorphosed sedimentary rock (killas), occasionally with quartz or other species. Strictly reference material in appearance, sizes from about 4cm to 8cm across @ 20.00, 30.00 and 45.00 each, depending on coverage.

CELESTINE with CALCITE- Mojina Mine, Constitucion, Chihuahua, Mexico
These attractive specimens were acquired circa 1965, originally labeled and noted as coming from Constitucion in Chihuahua, as reported by Panczne. This appears to be more accurate for the Mojina Mine, rather than the more distant town of Ricardo Flores Magnon specified on Mindat. The specimens are attractive, consisting of small, pale blue celestine lightly scattered over white popcorn to cauliflower-shaped calcite groups, some fluorescent (SW UV
green) due to a thin hyalite opal coating. Old specimens found in storage after more than 50 years, sizes from about 5cm to nearly 10cm across at just 20.00, 35.00 and 55.00 each. Very appealing stuff!

CHALCOCITE with MALACHITE etc.- Painsedale, Houghton Co., Michigan
A large, massive ore specimen of bluish-black, metallic chalcocite comprising matrix, the specimen showing a thin rim of green, crusty malachite on most surfaces. Micro azurite has been noted in a few tiny voids, and the locality has produced identical-appearing anilite as an admixed sulfide, likely here as well. Prehaps from the Champion Mine, but not attributed as such, this thick, triangular piece has one edge-face cut and measures about 10x8x4 cm @ 75.00. Very heavy!

CHAMOSITE- Ale & Cakes Mine, Gwennap, Cornwall, England
Dull greenish matrix composed of EDS-confirmed platy micro chamosite, often hosting tiny black cassiterite crystals and masses, and occasionally with quartz or various sulfides. The mineral was previously unrecored for this interesting locality, and our image of the material has recently posted to Mindat.org. Specimens range from about 4cm to 7cm, all rather ugly, but priced reasonably at just 15.00, 20.00 and 35.00 each, accompanied by a copy of our EDS spectra.

CRANDALLITE pseudo @ FLUELLITE- Lucin, Box Elder Co., Utah
From the famous minyulite find, these are micro, somewhat frosty white fluellite crystals partially replaced by crandallite. Most are associated with exceptionally attractive, minyulite needles and sprays, occasionally with carbonate fluorapatite and possibly other phases. A highly unusual pseudomorph, specimen sizes from about 2.5cm to 6cm @ 15.00 25.00 and 40.00 each.

DIAMOND (4.43 cts)- Udachnaya Mine, Siberia, Yakutia, Russia
A rather large single crystal, free of matrix, here as a nicely striated octahedron measuring about 10x7mm. The stone has good translucency for its 4.43 carat weight, color a pale greyish to clear hue. One only, from this large open-pit mine that exceeds 600 meters in depth! Competitively priced at just 785.00; one only!

DICKITE- Imitir Mine, Tinghir Province, Morocco
An odd locality and color for this kaolinite-serpentine group species, here as pale greenish blue (!!) masses wellscattered on matrix. Confirmed by both EDS and Raman, included secondary copper mineralization impurities are likely the source of the unusual color (see our image on Mindat.org). Only a couple of samples on hand, avering about 5cm across @ just 30.00 each.

EASTONITE- C.K. Williams Quarry, Easton, Pennsylvania
This relatively uncommon species defined in the IMA's new nomenclature as a trioctahedral K-Mg-Al mica, occurs as pale greenish, somewhat pearly and platy aggregates richly scattered in matrix, occasionally with an uncommon antigorite-lizardite polysomatic layering. First described in the 1890s, subsequently rejected, then approved once again in 1998. This Northampton Co. quarry has been designated as the type locality, only a few specimens on hand ranging from small TNs to 2cm @ 15.00, and larger samples to 5cm across @ 40.00 each, half the price of our small 2006 stock that was depleted long ago!

FERBERITE var: WOLFRAMITE- Cligga Mine, Perranporth, Cornwall, England
Rather non-descript, black splendant masses of ferberite nicely scattered in matrix, most with silvery arsenopyrite and occasionallyt chalcopyrite etc. A classic English locality, good reference specimens from 3cm to 5cm across @ 15.00 and 30.00 each.

FLUORITE with QUARTZ- Marienbergschacht,Wolsendorf,Bavaria Germany
An old specimen from this classic locality, long-closed and completely backfilled nearly 40 years ago. The fluorite on this sample has the attractive honey-orange colored cubes and octahedral crystals to a few millimeters wellscattered over the entire piece, often overlaying drusy quartz. The piece is accompanied by a tattered German label, overall specimen a generous 11x7cm @ 150.00.

GAUDEFROYITE- N'Chwaning II Mine, Kuruman, Rep So Africa
Superb groups of handsome, brilliantly lustrous small black elongated hexagonal crystals of gaudfroyite perched on and covering black manganese ore matrix, some with minor calcite and/or hematite as well. Excellent for the species, these are half the price of similar material of 20 years ago. Only a few specimens on hand, sizes range from TNs @ 25.00 to 4cm specimens @ only 55.00 each! List alternates!

GERMANITE (ex-L. Perloff)- Tsumeb, Oshikoto Region, Namibia
Mounted micromounts, ex-Lou Perloff (perloffite) Collection, and labeled in his own hand! This rare classic occurs as somewhat pinkish grey metallic aggregates, here crudely crystallized in better samples with good photographic potential for the species. Great provenance, but only a few available, priced at 150.00 each.

GMELINITE-Na etc.- Flinders, Victoria, Australia
Moderatelyt colorful pale pinkish to white gmelinite-Na lines cavities in basalt matrix, often with analcime, natrolite or other zeolite-related species. Old stock from an Australian dealer recently uncovered in our warehouse, specimens range from about 2.5cm to 6cm @ 15.00, 25.00 and 35.00 each, depending on quality.

JOHANNSENITE- Black Hole Prospect, Aravapai Dist. Arizona
Brownish radiating columnar sprays and divergent aggregates of johannsenite richly comprising matrix, originally from the first discovery of the species in Arizona in the early 1960's by the USGS.

Excellent micro crystals of olive green molybdofornacite lightly scattered on matrix, occasionally associated with a wide range of other species. A moderately rare mineral in well-formed, elongated tiny crystals from the Yellow Pine Extension, the mineral has been EDS-confirmed for Mo>Cr content, and a copy of our analytical work accompanies each specimen. (We have found no fornacite thus far, and some earlier reports of the mineral at the locality may
have been in error due to overlapping EDS peaks of Pb and Mo which an inexperienced operator might miss!). Recently featured in the October, 2018 issue of Mineral News, fine micro material, specimens range from about 2cm to nearly 6cm across @ just 15.00, 25.00, 40.00 and 65.00 each priced according to quality.

REBULITE in ORPIMENT- Jiepaiyu Mine, Changde, Hunan, PR China
This rare Tl-Sb-As-S mineral occurs here as tiny, dark grayish black submetallic pods sparsley scattered in brilliant yellow to orange-yellow orpiment matrix, occasionally with minor realgar and potentially other species. Analyzed material and from only the second known occurrence in the world, specimens range from 2.5cm up to 6cm across at 75.00, 125.00, and 250.00, depending on size and coverage, all with arrows and copies of our confirming analysis. The last of our stock for this exceptionally rare mineral!

RHODOCHROSITE etc.- Poudrette Q. Mont St. Hilaire, Quebec, Canada
We recently obtained a large MSH collection, most in micro to TN sizes, and found a good number of rhodochrosite specimens, most collected in the years of 1980-1986. The rhodochrosite forms mostly small rhombs, drusy crystals or platy rosettes, and the colors range from peach to pale pink with a variety of associations, most commonly aegirine, analcime, natrolite etc. Specimens are in the 2cm to 3cm size range and are priced according to quality at just 15.00, 20.00 and 30.00 each, all considered as micro material. If you would like a variety of habits/colors, we can supply a pleasing lot of three (3) different for just 55.00 per lot, all collected at least 30 years ago!

Named for Dr.Alla Boghanova, author's studied material, only a few available @ 245.00 each.

ALUMOHYDROCALCITE- Mt. Hamilton, Santa Clara Co., California
An attractive pink variety of normally white aluminohydrocalcite, these samples consist of tiny pink stringers, balls, and crystalline coatings scattered over a pale green to white jadeite-bearing, nickeliferous serpentine rock matrix. Once considered a chromian variety, aka knipovichite, this material from the eastern end of Mt. Hamilton was extensively studied in the 1980s that led to the discrediting of knipovichite. Decent looking stuff under the scope,
collected many years ago, from 2cm to 4cm @ 15.00, 25.00, and 40.00 each.

ARAGONITE- Spisska Podhradie, Rosnava, Slovakia
These are 1cm thick, superbly polished slabs of aragonite that show a ribbon-like, undulating pattern of white, tan and brown alternating bands completely comprising matrix. Reasonably attractive and finely polished on one face, this is from an unusual locality not known for the mineral. Sizes from about 7x3cm to 10x5cm @ 35.00, 40.00 and 45.00 each.

BABANEKITE (IMA 2012-007)- Fenugu Sibiri Mine, Gonnosfanadiga, Italy

CALCITE- Lucky Jew Mine, Treece, Cherokee Co. Kansas
Sharp scalenohedral calcite crystals to 2cm richly scattered on and comprising matrix, these from an excellent, older Tri-State District locality. The pointed crystals are transparent to translucent, some showing minor included chalcopyrite, typically colorless to slightly yellowish in hue. Purchased in 1967 from "Rosy" Rosenberry, noted dealer in Tri-State material. Only a few groups available, sizes from about 7cm to 9cm across @ just 45.00 each. See our image on Mindat.org.

CASTELLAROITE (IMA # 2015-071)- Monte Nero Mine, Rocshetta Vara, Italy
This moderately new species occurs as colorless, somewhat vitreous to silky aggregates sparsely scattered on brown metachert matrix. Formula: Mn2+3(AsO4)2*4H2O - monoclinic, IMA #2015-071. Named for Fabrizio Castellaro, collector and discoverer of several new species. type locality material, structurally related to metaswitzerite. Sizes from about 1.5cm to 2.5cm priced according to quality, not size, @ 75.00 and 95.00 each, with modest micro potential on the better specimens.

CERIANITE-(Ce)- Morro do Ferro, Pocos de Caldas, MG, Brazil
From old material acquired more than thirty years ago, we have a small supply of this uncommon mineral, offered as tan, powdery masses contained in a capsule. The mineral is the Ce-analog of uraninite and thorianite, and was mentioned from the locality in Chem. Geol. 55. (1986). Only a few samples available @ 25.00 each.

CIRIOTTIITE (IMA 2015-027)- Esperance tunnel, Tavagnasco, Torino Italy
This relatively NEW SPECIES occurs as microscopic, black metallic tubular fibers very sparsely scattered in chalcopyrite-rich quartz matrix.

Only a few 2.5cm matrix specimens on hand @ 175.00 each, all with good micro potential.

COLUMBITE-(Fe)- Spinelli Quarry, Glastonbury, Connecticut
Rich, dark brown subhedral columbite-(Fe) from this classic eastern locality, most largely comprising matrix. A few of the very best specimens will have black, more highly lustrous samarskite-(Y) associated as well, and allspecimens are priced according to degree of crystallization and size, overall from about 2cm to 3cm @ 20.00, 30.00, and 40.00, with a few larger samples, some with minor samarskite-(Y) to 5cm @ 75.00 and 125.00.

CREEDITE- Aguiles Serdan, Chihuahua, Mexico

Old stuff from a famous find, most with micro potential as well!

CUPROPEARCEITE- Sarbay Mine, Rudny, Kostanai Oblast, Kazakhstan
This rare species occurs here as flattened platy crystals forming small rosettes of micro groups with little or no matrix. Described from a single museum specimen and approved in 2007, these samples are far superior to the type sample that was in extremely tiny (0.3mm) masses. Formula: [Cu6As2S7][Ag9CuS4], trigonal, IMA #2007-046. This is a moderately new member of the pearceite-polybasite group with Cu prevaling over Ag in the A module layer of the structure, and these were studied by both XRD and microprobe. Most of the pearceite-polybasite group minerals at this, the type locality, are ordinary pearceite with Ag>Cu at the A site, and these are indeed rare! Only a two small groups available, all with good micro potential as well, averaging about 3mm across @ 195.00 each!

DIAMOND- Dudno Region, Lunda Province, Angola
From the old stock of well known dealer David New, we offer an interesting selection of small diamond crystals from this rarely offered locality. Each crystal is a modified dodecahedron or octahedron and measures from 2mm to nearly 3mm, with a color range from transparent white to yellow to greenish brown hues. We offer these transparent diamonds @ just 20.00 each, or a lot of three different @ just 55.00 per set. Excellent locality material!

EULYTINE- Linka Mine, Lander Co., Nevada
Atypical pale greenish masses of eulytite scattered on rock matrix, occasionally with intermingled bismutite as well. Structurally confirmed material from this uncommon bismuth mineral locality, sizes ranging from about 2cm up to nearly 6cm @ 20.00, 35.00 and 55.00 each.

This type locality specimen is a 1 cm square accompanied by multiple SEM images and complete analytical chemistry for each of the two separate flamite bands identified in the SEM images. Only one superbly documented sample available for this relatively new species @ 450.00. List alternates!

FORNACITE etc.- Silver Coin Mine, Humboldt Co., Nevada
Tiny, pale yellow-green crystal groups in sparse, isolated patches on quartz matrix, typically associated with mimetite, barite, chrysocolla and potentially a host of other species. Over 100 different minerals have been reported from this prolific locality, these samples acquired in 1992 before many of the new and rare species were described. Specimens range from about 2cm to nearly 5cm across @ just 15.00, 25.00 and 45.00 each, all with modest micro potential as well.

GOLD- Homestake Mine, Lead, Lawrence Co., South Dakota
A small gold in quartz specimen that once resided in my personal collection recently found its way back into my hands. The piece has several tiny native gold flecks, the largest (and only easily visible one) about 3mm across. Homestake was the largest and deepest gold mine in North America before it closed at the end of 2001, and despite its lean ore, produced over 40 million ounces of gold during its lifetime. A classic locality piece with my original label, overall size about 4x3cm @ 125.00.instructions.

GYPSUM- Alabaster, Iosco Co., Michigan
A large and weighty specimen comprised of a peachy-orange, columnar mass of gypsum, obviously removed from a thick seam, as this is an apparent cross-section with hints of matrix at top and bottom of this weirdly-hued monster. A large and colorfull locality specimen that some would consider as the variety selenite due to its translucent nature. The specimen is an impressive 16cm tall & about 9cm across, quite solid and heavy just 75.00.

GYPSUM (ROSE)- Permian Cu Deposits, Stonewall Co., Texas
Well formed, complex groups of gypsum roses nicely intergrown and forming attractive groups without matrix, colors ranging from greyish to brownish red. The individual blades are typically thin and flattened but radiate into multiples forming the bladed groupings. Old material from a relatively obscure area of Texas, acquired circa 1962 (!!). Moderately attractive specimens from 5cm to nearly 9cm across @ just 15.00, 25.00 and 45.00 each.

HEULANDITE-Ca etc.- Paterson, Passaic Co., New Jersey
Old specimens from the H.E. Moore Collection, typically as small vitreous to pearly crystals richly scattered on dark greenish basalt matrix, typically with drusy quartz, laumontite and possibly other zeolite-related species. Collected in the 1950s and 1960s, these are moderately attractive east coast specimens, ranging in size from 3cm to nearly 10cm across @ just 10.00, 20.00, 35.00 and 50.00 each. Many of these will also have micro potential as well.

LAUEITE with STUNZITE etc.- Hagendorf Sud, Waidhaus, Bavaria, Germany
A large specimen, ex-Renaud Vochten Collection, acquired in 1978 from G.H. Kummer, showing many tiny, orange-brown wedge-shaped laueite crystals lightly scattered on typical gossan matrix, with small sprays of micro strnzite needles evident as well. Numerous other phosphates from this prolific locality are likely present, as the locality has produced over 185 species to date, with two dozen type specimens as well during its 90 years of operation, closed now for more than 30 years. Overall specimen size a hefty 10x9cm @ 125.00. One only, and it begs to explored and potentially broken up into scores of mounts!

MANGANONORDITE-(Ce)- Karnasurt Mt., Lovozero, Kola, Russia
Small aggregates of glassy, smokey brown to yellow-brown masses of this rare mineral sparsely scattered in matrix on matrix. Formula: (Ce,La)(Sr,Ca)Na2Mn(Zn,Mg)Si6O18 and IMA-approved in 1997. Type locality material, only two small specimens available, average size 1.5cm across @ 255.00 each.

MARCASITE on CALCITE- Elk Creek, Meade Co., South Dakota
A highly unusual occurrence of marcasite, here as tiny botryoids and wedge-shaped micro crystals lightly scattered on bright yellow calcite seams fully overlaying dark Pierre Shale matrix, many with small secondary yellow calcite crystals growing from the calcite substrate as well. A very scarce association at the locality, these from a single find during a recent mining venture. Specimens from 5cm to 7cm across @ 40.00 and 55.00, a few large specimens to 13cm(!!) @ 150.00. Colorful and interesting material!

MELANOPHLOGITE- Fortullino, Livorno, Tuscany, Italy
Moderately attractive, glassy transparent balls to 3mm of this uncommon species scattered on pale rock matrix. More pleasing in appearance than the California material, the botryoids are somewhat more isolated and make interesting micro's as well if trimmed. From material collected in the 1970s, specimens from 2cm to 6cm @ 15.00, 40.00 and 65.00 each, depending on size and coverage.

OXYPLUMBOROMEITE etc.- Green Antimony Mine, Pershing Co., Nevada
This small deposit was worked as far back as 1918, but has seen little activity since the late 1960s, as far as we know. The oxyplumboromeite occurs as pale yellow to darker yellow crusts and elongated micro aggregates (likely pseudomorphs after jamesonite and sometimes coating thin gypsum needles) on massive quartz, occasionally with other species, and some with modest micro potential. A full study of the assemblage is underway for a future Mineral News article. Specimens on hand range from about 2cm to nearly 6cm across @ just 10.00, 20.00 and 40.00 each.

PICKERINGITE- Cerros Pintados, Tarapaca, Chile
Pure white, fibrous spikey aggregates of this uncommon sulfate packaged in a 3x3cm hinged plastic box. Very old, type locality material, ex-A.E. Seaman Mineral Museum, but a limited amount of material on hand at just 20.00 per box.

QUARTZ var: PETRIFIED WOOD- Mahajanga Province, Madagascar
Fairly attractive, limb cross sections of colorful petrified wood, these showing pleasing cream-brown-red combinations with good luster and patterns, polished on one side. These appear to be the conifer genus Araucaria, these sliced ovals average about 6cm in diameter @ just 20.00 each.

RHODOCHROSITE- Imuris, Mun. de Imuris, Sonora, Mexico
Massive, pink cleavages of rhodochrosite with little or no matrix, originally purchased in 1959.

The label indicates the mine was near Bovill(e) which is actually just over the border in Latah County. An interesting, old locality piece, overall size about 7x6cm @ 45.00, with old label.

TANGDANITE- Lovelock Mine, Bolivia, Churchill Co., Nevada
This relatively new mineral occurs here as micro pale blue to blue-green acicular crystals and sprays perched on matrix. Collected many years before it was properly described, these have been XRD-confirmed and are the only approved Ca-Cu arsenate-sulfate mineral known, IMA 2011-096. These are the best of a modest lot and will all yield excellent micromounts and colorful TNs and miniatures as well. Associations can include tiny azurites, brochantite and many other potential secondary minerals. Only a few samples on hand, sizes range from about 2cm up to nearly 6cm specimens @ 25.00, 40.00, 60.00 and 85.00 each, priced according to quality.

Only two specimens available, about 1.5cm @ 150.00 each.

UVITE TOURMALINE- Brumado, Bahia, Brazil
Deep, rootbeer brown crystals and aggregates of uvite scattered on dolomite matrix. Whether these are fluor-uvite or the OH-dominant end member is unknown, as both species occur at the locality. Since our EDS analytical techniques cannot quantify (OH), we are labeling these simply as "uvite". Originally obtained from Carlos Barbosa many years ago, specimens average about 2.5 to 3cm across @ 20.00, 25.00 and 35.00 each, depending on quality and crystal size.

We've spotted a few with hematite tips and occasionally other species, and these make colorful and attractive specimens as is, with really extraordinary micro potential if you care to break them up. Specimens range from about 2.5cm to nearly 6cm across @ just 8.00, 15.00 and 25.00

WAGNERITE in TRIPLITE- McMahons Quarry, Olary, S.A., Australia
This uncommon species occurs here as massive aggregates intergrown with dark brownish triplite comprising matrix. From an old find of many years ago, we have a few specimens only, sizes ranging from about 1cm to 3.5cm @ 15.00, 25.00 and 45.00 each.

WAIRAKITE- Tohi Mine, Izu, Shizuoka Prefecture Japan
This uncommon zeolite occurs here as translucent white to clear glassy aggregates scattered in vugs in matrix. Excellent locality material, but only a few samples available, sizes average about 3cm @ 55.00 each.

WAVELLITE- Crystal Baron Mine, nr. Crows, Arkansas
Collected in 1993 from this Saline Co. locality, these unusual wavellites show both an odd yellow color as well as a bright green SW-UV fluorescent response. Analytical work shows just wavellite, but these attractive botryoidal specimens also show trace amounts of strontium, manganese etc. that may be causing the fluorescent response. Attractive material nonetheless, sizes from 2.5cm to 5cm @ 10.00, 20.00 and 35.00 each. Interesting!

WAYLANDITE with BISMITE- Mumba, Kivu Province, Zaire
What were probably single crystals or solid masses are now well-rounded stream worn examples of yellowish bismite surrounding brownish-black masses of the rare Bi-Al-phosphate, waylandite, possibly with other Bi-phases present as well. Analyzed material, in sizes from 0.6 to 1.5 cm @ 25.00, 35.00 and 45.00 each.

ZUBKOVAITE (IMA #2018-008)- Arsenatnaya Fumerole, Kamchatka, Russia
Another NEW SPECIES in colorful micro aggregates from the Tolbachik Volcano, here as bright blue druses and botryoidal knobs on matrix, typically coated by water-clear anhydrite and often associated with the rare Na-Ca-Mg arsenate mineral johillerite in lilac-colored druses. Formula: Ca3Cu3(AsO4)4, monoclinic, IMA # 2018-008. The mineral is a new structural type, the first reported anhydrous Ca-Cu arsenate! Only a few specimens on hand, averaging about 1cm across, all with good micro potential and associations @ 200.00 each. List alternates!

CATALOG 21804 – Volume XLV, No.4

ALMANDINE etc.- Zillertal, North Tyrol, Tyrol, Austria
From the area near Pfitsch Pass, an old specimen comprised of fine-grained schistose/quartz matrix, shot through with scores of small dodecahedral crystals of almandine garnet,associated with inor hematite, clear albite, clinochlore etc. The piece is ex-Czech National Museum and is accompanied by their label, overall specimen size is about 7.5x4cm @ just 40.00. A good reference sample from this prolific area with some micro potential as well!

ANALCIME with CALCITE- Croft Quarry, Leicestershire, England
Rather well formed, transparent too translucent analcime crystals perched on matrix, all with small druses of white calcite, some showing secondary growth. Collected about 20 years ago from the quarry which sits near the small town of Enderby, only a few specimens available, sizes from 3cm to 6cm @ 15.00, 30.00 and 45.00 each, priced according to quality.

AUGITE with FRANKLINITE etc.- Franklin Mine, Franklin, Sussex Co., New Jersey
Flattened aggregates of dark augite richly scattered in and largely comprising matrix, here with minor franklinite, micro impregnating willemite and trace calcite as well, the latter two fluorescent, of course. This hefty specimen is ex-Dr. Pete J. Dunn Collection and is accompanied by his label, overall specimen size about 8x8cm @ 45.00. One only, with excellent provenance from the master researcher of this prolific locality!

AUSTINITE- Gold Hill, Tooele Co., Utah
From the depths of the warehouse, excellent vitreous micro crystals of austinite richly scattered in opened seams of limonitic matrix. Fine for the species, old material from this famous locality, many with superb micro potential as well. Matrix sizes from 2cm to 8cm across with corresponding coverage @ 7.50, 12.50, 20.00, 35.00 and 50.00 each. Nice!

BERTRANDITE in QUARTZ- Mt. Antero, Chaffee Co., Colorado
Old Wards Natural Science specimens comprised of densely aggregated quartz showing small, lustrous bertrandite crystals and aggregates sparsley scattered in exposed vugs in the quartz. A copy of the original label accompanies each specimen, the Dana number (422) on the label suggests the Sixth edition (1892) of Dana's System was used as the referenced source by Wards, providing perhaps a snapshot of when the material was acquired. Sizes average about 3cm across @ just 35.00 each. Old stuff!

BOYLEITE on BIANCHITE- Muzhievo, Beregovo, Transcarpathia, Ukraine
Two new minerals for the locality, here as elongated anthodites comprised of intergrown parallel aggregates of bianchite that have altered at their surface to white, columnar boyleite. Excellent for the species, from a new find at this locality that is near the Hungarian border. Specimens average 1.5-2cm @ 95.00 each. Only a few available!

CALCITE- nr. Black Rock Desert, Humboldt Co., Nevada
Excellent, well-formed and sharp, frosty white scalenohedral calcite crystals without matrix that are singly terminated, most showing a bluish-white SW UV fluorescence AND phosphorescence, plus a pale yellowish response to LW UV! The larger crystals show the better UV responses, crystal sizes from about 2.5cm to 5cm long @ only 7.50, 12.50 and 17.50 each. Neat!

CALCITE- Delta Carbonate Quarry, York, Pennsylvania
Collected about 25 years ago, the calcites from this quarry were often tinted orange by iron staining and inclusions, but this large display specimen shows numerous lenticular twinned crystals to 2cm across richly covering matrix, but with just a hint of color, resulting in a pleasing, large display piece that measures a hefty 19x12x10cm @ just 150.00. One only!

CELESTINE- Sakoany Deposit, Mahajanga Prov., Madagascar
Most collectors are familiar with the transparent, pale blue, chisel-shaped celestine crystals in geode-like vugs from this prolific locality. A small lot of excellent, steeply pyramidal crystals recently came to light, highly unusual in that they are sharply tapered and pointed, rather than the more common broad, squat crystals seen so often. Only three specimens retrieved from a very large lot, with pointed crystals up to 2.5cm long protruding from broad, geode-like vugs, with overall hand specimen sizes averaging about 8x6cm @ just 65.00 each. Don't miss these!

CRYPTOPHYLLITE- Tsentral'nyi Mine, Rasvumchoor, Khibiny, Russia
From the type locality for the species, these are from a relatively new find that was far superior to the original some ten years ago. In this instance, cryptophyllite occurs as tiny, colorless, elongated micro crystals and lath-like aggregates up to a couple of millimeters on pegmatitiic matrix. These are nearly 10 times larger than the first find of the mineral, and associations here include aegirine, sodlaite, K-feldspar, polymineralic pseudos after eudialyte and other potential species! Specimen sizes range from about 3cm to 5cm across, and these will offer some fine micros of a very rare, one-locality species @ 145.00 and 185.00 each, depending on quality.

DIAMOND (3.68 cts)- Argyle Mine, Western Australia, Australia
A rather large, flattened octahdral diamond crystal without matrix, showing lustrous faces and translucent, dark grey hue. Due to its rather flat presentation, the crystal looks quite large, measuring a full 10mm across and 6mm wide. A relatively modern locality known for its brightly colored pink diamonds and other unusual colors. One only, the stone weighs an impressive 3.68 carats @ only 395.00.

FLUORITE var: TIFFANY STONE- Bell Hill Mine, Spor Mtn., Juab Co., Utah
A very weird fluorite occurrence, here as pale purple, opaque masses as veins and interstitial fillings among chalcedony streamers staining tuff matrix, some showing a distinctive boxwork structure and often fluorescence due to the chalcedony and/or hyalite and possible calcite/dolomite associated in the matrix. Occasionally used as a striking lapidary material, this "Tiffany Stone" variety of fluorite is perhaps the strangest fluorite we have seen in
some time, these samples collected about 30 years ago. Specimens range from 3cm to 12cm (!!) across, all with odd forms, @ 7.50, 15.00, 30.00 and 50.00 each. You really need to have one of these!

GYPSUM "Desert Rose"- Sahara Desert, Ouargla Province, Algeria
These are interesting, well formed desert roses from an uncommon locality in the Sahara Desert, formed by interlocking tabular crystals of pale brown to redish gypsum to several centimeters across. Rather attractive and undamaged roses, supposedly from the area around Mnaguer (unverified), overall group sizes averaging 5cm to 6cm long @ just 15.00 each. Neat locality and pleasing to look at!

HAGGITE- Section 33 Mine, Grants, McKinley Co New Mexico
Among the ugliest of all minerals, haggite occurs as tiny, black monoclinic grains and aggregates scattered in sandstone matrix. One of the more obscure vanadium minerals, occasionally with trace, pale yellowish meta/tyuyamunite and/or minor pyrite. Old Cureton material, only two specimens on hand, sizes average about 4.5cm across @ 55.00 each. List alternates! Some South Dakota material also available; inquire!

HOLMQUISTITE- Foote Mine, Kings Mt, Cleveland Co., North Carolina
Representative samples of holmquistite in which aggregates of small bluish-black, micro prismatic crystals are flattened, providing a densely intergrown, fine-grained surface. Interesting specimens from old E. Wm. Heinrich material, famous professor of geology at the University of Michigan and editor of American Mineralogist. Specimens from about 4cm to 8m across @ 20.00, 35.00, and 55.00 each.

ILVAITE- Huanggang, Hexigten Banner, Mongolia, PR China
From the Chifeng Precture in Inner Mongolia, these are among the finest ilvaite crystals we have ever encountered! Singly terminated, elongated and lustrous prisms from 3.5cm to 4cm tall are just 45.00 each. We have a pair of finger-thick, DOUBLY TERMINATED rod-like crystals that are just over 8cm (!!!) tall, matrix free, and with wellformed, black prismatic habit! Each sample is very conservatively priced at just 200.00. In addition, we have two, thick and highly lustrous stout groups as well, these ranging from 6cm to 7cm tall, as much as 4+cm at the base, and comprised of two or more individuals that are intergrown and each wonderfully terminated at one end @ 350.00 each. Great specimens; list alternates!

JUNITOITE- Christmas Mine, Gila Co., Arizona
Nice, sharp platy microcrystals and thin crystalline plates of colorless to white junitoite are scattered over a skarn matrix. Possible associations include kinoite, ruizite, etc. named for crystallographer Jun Ito who worked with Dr. Paul Moore at the University of Chicago. Good coverage in these older specimens, ex-Cureton material, 3cm to 6.5cm @ 15.00, 25.00, 40.00 and 60.00 each.

KENTROLITE- Big Chief Mi, Hillsboro, Sierra Co. New Mexico
From one of the premier localities for the species, kentrolite occurs here as black, submetallic orthorhombic micro crystals, aggregates and globular, radiating groups scattered in seams and vugs on matrix, some of the better specimens associated with rare transparent, colorless, hexagonal vanadinite crystals as well! Excellent micro material, priced according to size, richness and associations, overall from 2.5cm to nearly 5cm across @ 15.00, 30.00 and 45.00 each.

KHRENOVITE (IMA #2017-105)- Arsenatnaya Fumerole, Tolbachik, Kamchatka, Russia
Another NEW SPECIES from the second scoria cone of this Kamchatka volcano, here as minute, honey-orange hued crystals without matrix, each sample carefully mounted on an adhesive disk. Formula: Na3Fe3+2(AsO4)3 - monoclinic, IMA # 2017-105. The mineral is named for Russian volcanologist Anatoly Petrovich Khrenov (1946-2016) who made significant contributions to the studies of the Kamchatka volcanoes. Exceptionally rare, only five crystals available @ 185.00 each; type locality material from the author, of course.

LAUMONTITE on FLUORAPOPHYLLITE-(K)- Prospect Park Quarry, Paterson, New Jersey
An old specimen comprised of an open void in basalt that exposes a small group of translucent fluorapophyllite-(K) crystals, the major one about 1.2cm across, with numerous, tiny prismatic crystals of pearly white laumontite scattered about the vug that measures about 3.5x2.5 on its surface. The locality is being completely backfilled and is no longer productive. The piece is ex-Upsala College and is accompanied by their label, overall size of the
specimen is 9x6cm @ just 35.00.

LAZURITE (Lapis Lazuli)- Koksha Valley, Badakhshan Province, Afghanistan
Much of the cutting material currently on the market has come from this region, and we recently uncovered a box of TN-sized specimens that were likely from an older cutting operation. These are relatively solid chunks of blue lazurite, unpolished, their color greatly improved from dull blue to brillaint blue when wet or polished. You can expect trace pyrite in some, white calcite in others, but no crystals are evident. Really affordable as 2cm to 2.5cm rough at just 6.00 each, or 5 for 25.00.

MACEDONITE- Langban, Varmland, Sweden
This moderately rare species occurs in two distinct habits: as minute, slightly greenish-yellow masses in celsianrich dump material, and as dark, nearly black rounded grains in andradite-rich ore. Not at all attractive and quite lean, but rarely offered from this prolific locality. Sizes range from 1cm to 2cm across @ 75.00 and 100.000 each.

MENDELEEVITE-(Ce)- Dara-i-Pioz, Tien Shan, Tadjikistan
This extremely rare occurs as minute, cubic interstitial fillings among a quartz/pectolite matrix, offered here as a tiny fragment mounted in a 2cm probe mount and elegantly documented with a large, backscatter SEM image and Xray spectra that are provided This moderately new cesium-dominant phases is IMA #2009-092, formula: Cs6(REE22Ca6)(Si70O175)(OH,F)14H2O21 - isometric, with cerium being the major REE after cesium. Only one documented specimen available @ 325.00.

NESQUEHONITE- Nesquihoning, Carbon Co., Pennsylvania
A superb specimen from the type locality for the species, rarely seen in today's market. The piece shows greyish white to beige upright crystal sheaves radiaiting from a small coal matrix, with small, dull white masses of what is likely lansfordite, the other type locality species found here. The specimen is ex-University of Arizona, originally from the Rukin Jelks Collection (1927-2014), former Chairman of the Arizona-Sonora Desert Museum. The piece
measures about 4x2.5cm @ 300.00. One only, with both labels accompanying, top quality for this species and type locality!

PAPAGOITE- New Cornelia Mine, Ajo, Pima Co., Arizona
This uncommon mineral occurs as blue masses and thin streamers in seams and on the surfacec of brownish, quartz monzonite matrix, here from the type locality for the species. The locality has also produced ajoite (type locality), as well as more than 80 other minerals! Acquired circa 1965, specimens with good color from about 2cm to 5cm across @ 15.00, 30.00 and 55.00 each, depending on coverage.

PATRONITE with "QUISQUEITE"- Minasragra, Cerro de Pasco, Peru
An old and rich specimen comprised of dark bluish-black patronite intimately intergrown with "quisqueite", alternately now known as either a highly sulfurous carbon compound or vanadium-rich lignite. The material was first described in 1906 in the Engineering and Mining Journal, and later in 1907 in the Journal of the American Chemical Society. A rich hand specimen, accompanied by a heavily deteriorated J. Cilen label (with strange blue crustymineral growths!) AND an orignal Lazard Cahn label showing spotty deterioration as well, specimen size about 9x7cm @ 125.00.

PLACER CONCENTRATES- Long Valley, Valley Co., Idaho
From our materail desccribed in Mineral News (2018) Vol. 34, No.6, these are heavy mineral concentrates from the Cascade area dredge jigs obtained by noted geologist and mineralogist Prof. E.W. Heinrich in the 1950s. Our analytical work on these fascinating tiny grains shows predominant ilmenite, and each 5x1.5cm vial will likely have associated spessartine, magnetite, columbite-(Mn), monazite -(Ce), euxenite-(Y), yellow titanite, trace fluorescent zircon and others! Great looking under the 'scope, and a "must-have" for sand collectors @ just 10.00 per 5cm vial.

PYROLUSITE variety POLIANITE- Lake Valley, Sierra Co., New Mexico
These are thickly intergrown, needle-like aggregates of pyrolusite forming radiating masses of greyish black "polianite" scattered in sooty, black matrix, some likely admixed with ramsdellite which is more typically in blocky aggregates and crystals. EDS analysis confirms simple Mn-oxide, and the morphology is a useful key as well to this obsolete varietal name often used to differentiate crystalline pyrolusite from its botryoidal forms. Old material, sure to turn your hands black upon handling, sizes from about 2.5cm to 5cm across @ 8.50, 15.00 and 25.00 each, with analytical copy!

QUARTZ- Crystal Peak, Incline Village, Nevada
A large single crystal of smoky quartz without matrix, overall stands about 31cm tall(!!!) and collected in the distant past. Only one on hand, a monster that is dark brown, translucent crystal that is singly terminated and prepped to stand upright @ 2000.00. The largest one we have ever seen from the locality. Yikes!

QUARTZ- Minas Gerais, Brazil
A very complex and appealing, large rehealed multi-crystal of quartz with hundreds of offsets, steps, and parallelgrowth faces, the largest faces being up to 3 cm across. The overall piece is rather flattened, and if studied carefully, appears to be a single, contiguous crystal (and doubly-terminated at that), despite the hundreds of separate vicinal faces on multiple terminations on the specimen. The quartz itself is colorless to lightly smoky, mostly transparent, and highly vitreous. Muscovite crystals and crystal fragments (to about 2 cm) are randomly embedded in the quartz, giving it even more of an unusual look. One termination has some damage to the tip, but otherwise there is little or no damage on the display side of the specimen. This is definitely a good piece for those collectors interested in complex and/or irregular crystal forms. Specimen size: whopping 12x8x4 cm @ only 60.00.

RIOTINTOITE (IMA #2015-085)- La Vendida Mine, Antofasgasta, Chile
This relatively NEW SPECIES occurs as microscopic, colorless platy crystals and aggregates on matrix, occasionally associated with pale green eriochalcite or other phases. Formula: Al(SO4)(OH)3*#H2O - triclinic, IMA # 2015-085. Author's material, portion of type, only a couple of small smaples about 1cm across @ 250.00 each. List alternates!

ROBERTSITE- Tip Top Mine, Custer Co., South Dakota
This phosphate mineral, named for the well known mineralogist and author Willard (Bill) L. Roberts, occurs as medium to dark brown crystalline aggregatess scattered over a phosphate rock matrix. These samples were originally provided by Roberts to Julius Weber, and were recently uncovered here in our warehouse. Bill's personal label with his Harter Drive address in Rapid City accompanied the material, and we supply a copy of the W.L. Roberts label with each specimen from this small lot, the mineral distinguished by its radiating structure and associated with the typical group of secondary phosphates this locality is well known for. Only a few on hand, averaging 3cm to 4cm across @ 35.00 each, with the copy of the Roberts label. Sizes from 2.5cm to 6cm @ 15.00, 25.00, 35.00, and 50.00 each. Similar material from the White Elephant Mine also available - inquire!

ROSASITE- Mina Ojuela, Mapimi, Durango, Mexico
Bright blue botryoids of attractive rosasite scattered on limonitic matrix, occasionally with associated calcite and possibly other phases. These were acquired in the 1970s when Mexican material was at its peak, and many will also yield good micro material as well. Specimen sizes range from 2.5cm to 4.5cm @ 10.00, 20.00 and 35.00 each, depending on quality. Colorful and quite pretty!

SCHIZOLITE (IMA 2013-067-18B)- Wessels Mine, Kalahari, N. Cape Prov Rep South Africa
This NEW SPECIES is a redefinition of marshallsussmanite, occurring as delicate, pale pink aggregates, from this famous manganese deposit, these without matrix. Formula: NaCaMnSi3O8(OH), triclinic, a new member of the pectolite group with approved IMA #2013-067, updated as #18B. The material was first described in 1900 from Greenland, subsequently discredited, now approved as a redefinition of marshallsussmanite. From the 2013 author's material, small boxed specimens, quite pure, averaging about 5mm across @ just 55.00 each.SIUDAITE (IMA #2017-092)- Eveslogchorr Mt., Khibiny, Kola Peninsula, Russia
This NEW SPECIES occurs as minute, brownish orange masses, here generally without matrix and offered as <1mm fragment in a vial. The complex formula is: Na8Mn2+2Na)Ca6(Fe3+,Mn2+)3Zr3NbSi24(Si,[],Ti)O74(OH)2Cl*5H2O - trigonal, IMA #2017-092; a member of the eudialyte group. Found at the Astrophyllite Stream, this is author's material, portion of type @ 145.00 each.

SMITHSONITE on ORE- Tsumeb Mine, Oshikoto Region, Namibia
An old-timer from the Tsumeb heyday, here as excellent, tabular to grain of rice shaped transparent to translucent smithsonite crystals completely covering a heavy ore matrix comprised of fine grained galena, tetrahedrite and likely other sulfides intergrown and underlaying the smithsonite. The crystals are generally clear to slightly grey, but show a very subtle purple hue as well. Ex-Hamel collection, overall size about 10x5cm, quite heavy and with full
coverage on the top surface, competitively priced at just 150.00. One only!

STIBNITE- La Noria Mine, San Martin, Zacatecas, Mexico
From old material acquired circa 1965, these samples show thin, needle-like crystals of stibnite on matrix, some with transparent to translucent calcite scalenohedral micro crystals, and some even including the stibnite itself. Representative specimens that display well and will also yield good micromounts from an uncommon locality 50 years in the past, overall sizes from about 2.5cm to 5.5cm offered at just 7.50, 15.00 and 30.00 each.

STILBITE- Getchell Mine, Humboldt Co., Nevada
Water-clear micro crystals of spear-shaped, tabular stilbite richly scattered in seams and vugs on matrix, some associated with minor calcite, corroded realgar and possibly other species. Excellent micro material from a classic locality in which this zeolite has been rarely offered, sizes from 1.5cm to 6cm @ 7.50, 12.50 and 25.00 each.

SYLVITE w/ CARNALLITE, HALITE- Saskatoon, Saskatchewan, Canada
Deep brownish-red sylvite richly scattered and included in colorless, massive halite matrix. Excellent for the species and old material collected over thirty years ago, also with massive carnallite and possibly other included phases. Generous matrix specimens from 3cm to 6cm @ 8.00, 15.00, 25.00 and 40.00 each. A few large specimen to 12x7cm @ 85.00.

TRIAZOLITE (IMA #2017-025)- Pabellon de Pica Mt., Iquique Prov., Chile
Another NEW SPECIES from the Tarapaca Region, here as very minute, deep purplish-blue crystalline aggregates very sparsely scattered in matrix, and most will require a 'scope to see them properly. Formula: NaCu2(N3C2H2)2(NH3)2Cl3*4H2O, orthorhombic, IMA #2017-025. Author's material from the type. Matrix sizes average about 1 cm across @ 240.00 each. List alternates!

URANOPHANE- Margaritas Mine, Sierra Blanca, Chihuahua, Mexico

CATALOG 21803 – Volume XLV, No.3

ACANTHITE- Imiter Mine, Tinghir Province, Morocco
Excellent, crudely crystallized acanthite without matrix, here as dull greyish black spiney to blocky aggregates comprising matrix. These are likely from the 2007 find and recently uncovered in our warehouse. Attractive minatures mounted on clear leucite bases, groups average about 4cm and offered at just 95.00 each. Only a few on hand!

BAFERTISITE- Gremyakha-Vyrmes, Kola Peninsula, Russia
This uncommon mineral occurs here at Gremyakha Lake as tiny, orange-red glassy elongated aggregates lightly scattered in matrix, typically associated with black arfvedsonite and feldspars. The material is near endmember in composition, the highest Fe-rich bafertisite ever recorded, and named for its composition (Ba-Fe-TiSi). A few samples are available with micro aggregates, specimen sizes average 3cm across @ just 55.00 each.

BAYLEYITE over ANDERSONITE- Ambrosia Lake District, McKinley Co. New Mexico
Bright yellow, small cauliflower-like crusts and aggregates of this unusual Mg-U-carbonate richly scattered over matrix. Under the 'scope, careful study will show the underlying, pale green, micro andersonite as well. Both species are fluorescent (bright greenish), with andersonite showing greater SW-UV intensity. Originally acquired in 1966, this radioactive material makes excellent fluorescent specimens as well great micro potential samples. Coverage is very rich in hand specimens, and sizes range from about 2cm to 5cm @ 20.00, 40.00 and 60.00 each, richer and less expensive than the material we offered in 1996! Nice stuff!

BERAUNITE w/ FERRISTUNZITE- Blaton, Mons, Henegouwen, Belgium
Dark brownish green to nearly black sharp micro crystals of radiating beraunite lightly scattered on matrix, most associated with yellowish, straw-like needles and groups of ferristrunzite (for which this is the type locality for the latter). The matrix sports a dull, murky green botryoidal coating which appears to be chemically similar to mitridatite based on our EDS work, and only three specimens on on hand, all ex-Renaud Vochten Collection, sizes averaging about 3cm across at just 25.00 each, all with micro potential.

BISMUTH with ARSENOPYRITE- Puy-les-Vignes, Novelle-Aquitaine, France

BOOK
ROCKS & MINERALS- by E.P. Bottley
Author E.P. Bottley was best known as a London mineral dealer who purchased the J.R. Gregory dealership in 1931, becoming “Gregory & Bottley” and later “Gregory, Bottley & Lloyd” after his death in 1980 (many old collections have numerous specimens from this mineral concern, as do we in our warehouse.). His book, a hardcover, 95 page treatise, contains 113 color and black and white specimen images, and this lightly used and clean copy also has its original dust jacket. Size is about 26x21cm and is inexpensively offered at just 15.00 plus shipping.

EPHEMERA
PHELPS DODGE STOCKS
Perhaps one of the best known mining companies, Phelps Dodge was commonly associated with its operations at Bisbee and elsewhere in Arizona, but it also had extensive properties in New Mexico. Founded in 1834, it became the largest publicly traded copper mining company in the world when acquired by Freeport-McMoRan Copper & Gold in 2007. We recently located an old stash of Phelps Dodge Stock Certificates, these noted as interim shares issued in 1929 when the company offered a 4:1 split to its stockholders, only months before the market crash that led to the Great Depression. An orange-hued certificate was used for 100 share blocks, and a more rare, green certificate was used for smaller holdings. While we have seen these offered for as much as 30.00 each, we will send you one of each type for just 15.00 a pair! All are cancelled and are in generally good condition, showing normal wear. A neat piece of history!
GEM
TOPAZ- "Swiss Blue" Brazil
Excellent, faceted Brazilian topaz in an unusual 10mm heart shape, these are heat treated to yield a superb "Swiss Blue" color that is the most desirable of topaz hues. Well-cut, gemmy and fully transparent and eye-clean stones average over 4 carats each @ just 30.00 per stone, or a matched pair at 55.00. Very attractive!

Samples from 2.5cm to 8cm @ 15.00, 25.00, 45.00 and 65.00 each.

FRIEDELITE- 1180 Stope, 700 level, Sterling Hill New Jersey
From one of the few finds of CRYSTALLIZED friedleite at this prolific locality, the species occurred here in the Sterling Mine as minute, orange monoclinic crystals and druses scattered on brightly fluorescent willemite-rich matrix, typically with franklinite and non-fluorescent calcite. These are unlike the banded, somewhat waxy red, massive friedleite known from the district, originally obtained from Ewald Gerstmann (gerstmannite) in the late 1970s. We have a few samples on hand with modest micro potential, matrix sizes from 2cm to 6cm and priced
according to coverage and size at 20.00, 35.00, and 55.00 each.

HYDROROMARCHITE- Maximianus Herculius Coin, ~300 AD, Hungary
A bizarre occurrence of this rare tin mineral, here as part of a greenish blue alteration product on ancient bronze coins, minted in the early third century A.D. to honor the Roman Emperor (286-305 A.D.) Maximianus Herculius. These were unearthed in Hungary, and the alteration product includes admixed pseudomalachite and a smectite phase as well, in which the hydrromarchite occurs in 20-40 micron wide zones in the alterations. Chemically and XRD identified, each 1.7cm historical ancient coin is just 150.00. Limit one per order, please!

KAMENEVITE (IMA #2017-021)- Oleniy Ruchey, Mt. Suoluaiv, Khibiny Russia
This NEW SPECIES was found at the Oleniy Ruchey (Reindeer Stream) apatite mine, the deposit discovered by Russian geologist Evgeniy Arsenievich Kamenev (b. 1934) and for whom the mineral is named. It occurs as minute aggregates of colorless lamellae, typically associated with brown lomonosovite. Formula:
K2TiSi3O9*H2O - orthorhombic, IMA # 2017-021. Type locality and author's material, tiny specks mounted on 1cm adhesive disks @ 125.00 each. Limited availability!

KAOLINITE- Little Rock, Pulaski Co., Arkansas
A pair of dull,pisolitic hand specimens of kaolinite-rich matrix, very old specimens originally provided by Ward & Howell to the Michigan College of Mines. Rathe rugly stuff but with excellent, historical provenance, likely circa 1890s based on the labels. Sizes average about 8cm across @ 55.00 each.

MILARITE- Jaguarassu, Minas Gerais, Brazil
Each sample is a single hexagonal crystal section of milarite without matrix. These are pale green in color and the better quality specimens are nicely terminated at one end of the elongated prism. Old Carlos Barbosa material, overall lengths from 0.5cm to 1cm @ 15.00, 20.00 and 30.00 each, depending on color and clarity.

MORDENITE- Eagle Eye Mine, La Paz Co., Arizona
White tufts of needle-like, elongated mordenite micro crystals form dense bunches and aggregates of this fibrous zeolite on pale, brecciated matrix. From the original find at the locality by the late David Shannon in 1988, we have only a few specimens on hand, sizes ranging from about 3.5cm to 8cm @ just 10.00, 15.00 and 25.00 each, all with modest micro potential as well.

PALYGORSKITE- Pend Oreille Mine, Metaline Falls, Washington
Thin, leather-like flexible mass of this greyish mineral oddity without matrix; very weird stuff, (the "mountain leather" name is quite appropriate). Collected from the 500 level of the mine and purchased circa 1960 when the mine was active. Sizes average from about 4cm to 10cm across, all flexible and quite strange @ just 20.00, 45.00, and 75.00 each. A few monstes to 18cm long (!!) @ 125.00. List alternates!

PREHNITE on QUARTZ- Qiaojia, Zhaotong Pref., Yunnan, PR China
Pale green balls of prehnite to 1cm lightly scattered and perched on groups of transparent, vitreous quartz crustals that fully comprise the matrix of these attractive specimens. A few samples may show an underside of drusy epidote, pale feldspar or occasional inclusions as well. Nicely sizes samples that average about 8x5cm @ 55.00 each. Only a few on hand!

PYRITE & QUARTZ CASTS @ ???- unspecified locality Japan
A relatively large and interesting specimen comprised of countless small pyrite crystals, some up to several millimeters completely comprising matrix. Among the voids of the piece, and particularly covering one surface, are remnants of hollow tubular casts of quartz after an unknown mineral. An accompanying, old Kristalle label does not offer a specific locality beyond "Japan", but the piece is remeniscent of several localities on Honshu Island that a Japanese expert may readily identify. There is one small area of dull grey galena also associated, and the overall size of the specimen is a hefty 14x12x6cm @ just 150.00. One only!

QUARTZ- Goose Lake, Negaunee, Marquette Co., Michigan
A large and curious specimen comprised of elongated quartz crystals to 5cm long, tightly packed and intergrown in a 12x7cm exposed vein. A few of the crystals are curved(!!) or severely flattened and are growing out of a massive quartz base into the exposed rock matrix wall that capped the seam. Likely from the Lindberg Quarry,
but the A.E. Seaman Mineral Museum label that accompanies the piece merely gives "Goose Lake" as the locality. Overall size about 12x11x8cm @ only 70.00. A rather heavy piece from an uncommon locality with an odd habit!

REEVESITE- nr. Alpine Mine, San Benito Co., California
This uncommon species occurs here in the Clear Creek Canyon as pale, yellow-green filmy crusts and masses scattered over serpentine matrix. Old material collected nearly 40 years ago, specimens from about 2cm to 5cm across @ 10.00, 25.00 and 45.00 each. The last of our stock from this obscure Goat Mountain locality!

RICHELLITE- Richelle, near Vise, Liege, Belgium
Occurring as olive green to tan-green crusts on rock, richellite is a complex calcium iron phosphate. These relatively rich specimens were collected many years ago. Type locality material, not very attractive but quite representative and reasonably priced, sizes from about 1.5cm to 5cm @ 15.00, 25.00, 45.00 and 65.00 each.

SIDERITE with QUARTZ- Imilchil, Er Rachidia Province, Morocco
Attractive and fairly sharp, glassy rhombs of translucent, greenish-brown siderite to 2cm perched on crystallized quartz, these presenting well and of surprisingly good quality. We have seen similar material ascribed to the Iourien Mine near Tafraout, but our supplier assures us these are from Imilchil. Specimens average about 4cm across at just 45.00 each.

SIDERONATRITE- Capital Reef, Wayne Co., Utah
Bright yellow masses of sideronatrite richly scattered and covering matrix, here from a rather obscure locality now in a national monument area. Old Cureton material collected many years ago, specimens from about 2cm to 6cm @ 15.00, 25.00 and 40.00 each; a few to 11x11cm @ 85.00 each.

SIEGENITE- Brushy Creek Mine, Reynolds Co., Missouri
Minute silvery octahedral crystals of siegenite scattered on matrix, associated with lustrous black sphalerite crystals and dolomite rhombs. Excellent specimens with fine micro potential, these from a find nearly 20 years ago, sizes from small TNs of 1.5cm @ just 15.00, and a few larger specimens to 5cm @ just 45.00 each. A few from the nearby Sweetwater Mine are also available - inquire!

SPHALERITE with DOLOMITE- Monroe Co. Airport, Monroe Co., New York
An odd specimen showing a deep orange-brown, transparent and gemmy sphalerite crystal group about 1.3cm long perched in an exposed seam in dolostone matrix, associated with numerous, small saddle-shaped rhombs of white dolomite scattered about. Ex-A.E. Seaman Museum, and their label notes it was donated by well-known Michigan copper collector Don Pearce, and it further suggests it was likely deposited as fill at the airport, its original source more likely as construction stone from a nearby quarry like Penfield. Moderately attractive piece, size about 8x5cm @ 55.00.

TALC- nr. San Andreas, Calaveras Co., California
Rich, pale green waxy masses of foliated, crystalline talc comprising matrix, many showing unusual tabular "crystals" and aggregates. From one of the more prolific localities for the mineral, these are moderately attractive for an otherwise uninspiring species. Old material collected many years ago, sizes range from 2cm to 6cm across @ 8.50, 15.00, 25.00 and 45.00 each.

TOPAZ- Dassu (Haramosh), Gilgit, Pakistan
Transparent, pale honey colored single crystals of topaz without matrix, these showing typical stout, prismatic habit with fine pinacoid terminations and well developed prism faces. All show detachment points at the base, and as expected with facet-rough topaz crystals, there are the usual dings in these rather good crystals. Sizes are generous, ranging from 2.5x1.5cm to 4x2.5cm, very inexpensively offered at just 50.00, 75.00, 100.00 and 125.00 each, far below typical prices seen elsewhere!

URANINITE- Brudenell, Renfrew Co., Onatrio, Canada
Small but interesting uraninite crystals with little or no matrix, showing typical crudely cubic habit and submetallic luster. Collected by a well-known mineralogist/curator on private property some years ago, these range in size from about 8mm to nearly 1.5cm, and all are quite hot! Only a few on hand, priced at 35.00, 55.00 and 85.00 each.

XENOTIME-(Y)- Alexander Co., North Carolina
An old specimen comprised of a blocky, elongated partial crystal of xenotime-(Y) about 3cm tall protruding from a massive xenotime-(Y) matrix mass. The specimen is accompanied by a Neal Yedlin (!!) and Joe Cilen labal,
acquired by Cilen many years ago. While a specific locality in Alexander County is not noted on their labels, the piece is likely from the Hiddenite area that produced such material in the distant past. One specimen only, with labels, about 4.5x3.5cm @ 125.00.

ZIRCONOLITE-3T- Kyauk-Pyat-That, Mogok, Mandalay, Myanmar
This rare mineral has been found here in relatively large, brownish-black single crystals and occasionally as twins, measuring up to nearly 1cm tall. These are matrix-free and fairly sharp specimens from this prolific gemstone region, here as the rare 3-T polytype. The precise locality is likley the Myan Gyi Mine, and only a couple of crystals are available @ 150.00 each. List alternates!

AMMONIOALUNITE- Schoeller Mine, Kladno, Czech Republic
This relatively rare mineral (described 1989) occurs as white chalky flakes with little to no matrix. An interesting central European local for this ammonium sulfate, we have available grains packed in capsules @ 20.00 each, or matrix fragments ranging in size from 0.5 cm to 0.8 cm at 35.00 and 45.00 each.

ANDRADITE var: DEMANTOID- Campo Franscia, Sondrio Province, Italy
From specimens acquired over thirty years ago, we have a small selection of pale green, chromian andradite (var. demantoid) samples, with crystals to several millimeters nicely scattered on matrix, some with associated chrysotile or other phases. Specimens range from about 2.5cm to 5cm across, offered at just 15.00, 25.00 and 45.00 each.

ANNABERGITE- Candelaria Mine, Esmeralda Co., Nevada
Bright, apple-green to nearly clear micro crystals of transparent annabergite richly scattered in exposed seams on matrix from this uncommon locality. We have a large lot of reasonably priced material, sizes from 1.5cm to 10cm @ just 7.50, 15.00, 25.00, 40.00 and 60.00 each depending on size and coverage. Nice micro stuff!

BARITE- Hecla Rosebud Mine, Pershing Co., Nevada
Very odd, well-crystallized white to greyish white barite crystals and groups with little or no matrix, all showing an atypical, somewhat rhombohedral habit that is quite pleasing and very unusual for the mineral. From a find about 25 years ago, these are XRD-confirmed, stout, well-formed crystals averaging 1.5 cm to to 2cm across, with overall sizes up to 4cm @ 10.00, 15.00, 25.00 and 35.00 each, depending on quality. A few larger matrix specimens to 8cm @ 55.00 and 75.00 each.

BARWOODITE (IMA 2017-046)- Big Rock Quarry, Pulaski Co., Arkansas
This NEW SPECEIS occurs as deep, red-brown elongated aggregates sparsely scatted on white feldspar matirx, typically associated with delicate, more prolific pale brown needles of eggletonite, both type locality minerals from here. Formula: Mn2+6Nb5+(SiO4)2O3(OH)3, trigonal, IMA #2017-046. Occasional dark greenish black aegirine, minor yellowish masses of zircon etc. may be associated. A new member of the welinite group and named for the late Henry Barwood. Micromount material, matrix sizes average about 1cm @ 85.00 each.

BRAUNITE- Mamatwan Mine, Kalahari Mn Field, South Africa
This large open pit mine lies to the south of the famous Wessels and N'Chwaning mines, producing massive braunite with lesser hausmannite, hematite and "partidgeite", the latter a discarded name for a Mn2O3 phase found in the ore. We uncovered a large hand specimen of this braunite-rich ore, acquired in 1981 and comprised of sedimentary baunite lutite that occurs as dark greyish black masses comprising matrix, occasionally with minor, thin carbonate streamers of kutnohorite/calcite. Ex-Renaud Vochten collection, noted as XRD confirmed on the back of his his label. A fairly obscure locality that has produced about 30 different species, the specimen is quite dense and measures about 11x7 cm @ just 55.00.

CALCITE enclosing CHALCOPYRITE- Shuikoushan Mine, Hengyang, Hunan, PR China
Two transparent to translucent scalenohedral calcite crystals form much to this specimen, the tips of the crystals enclosing tiny, wedge-shaped chalcopyrite crystals easily seen at 10x. Larger balls of iridescent chalcopyrite are perched on and protruding from the surface of the base of the calcites as well. Growth chevrons and minute secondary copper minerals are evident on the bottom of the piece, adding to the charm and interest of this unusual specimen. Excellent locality piece, overall size about 7x5cm @ 75.00. One only!

CALCITE variety THINOLITE- 25 Miles N. of Nixon, Washoe Co., Nevada
These are strange calcite (calcareous tufa) pseudomorphs after an unknown (perhaps ikaite?) mineral, represented here by acute pyramidal crystals approximating tetragonal symmetry. Specimens show elongated spears of greyish calcite forming interesting boxworks and oddly shaped samples, often called glendonites, barleycorn pseudos, jarrowites and other terms, the exact name generally associated with a specific locality for these oddities. We first offered these in the early 1970s when obtained from the late Ted Morley, and our current stock was collected more than thirty years ago. Specimens from about 5cm to 10cm across @ just 8.50, 15.00, 25.00 and 40.00 each. Weird stuff!

CERITE-(Ce)- Bastnaes Mines, Riddarhyttan, Sweden
Type locality specimens of cerite-(Ce), occurring here as brown to pinkish brown masses scattered in matrix, potentially with dark ferriallanite-(Ce) or other admixed phases. Old material, specimen sizes from about 2cm to 5cm across @ 20.00, 35.00, 55.00 and 75.00 each, one slightly larger with flattened sprays of anthophyllite @ 125.00.

CHONDRODITE with GRAPHITE etc.- Pargas, nr. Turku, Finland
From the type locality for the species, a large hand specimen of white calcite with tiny, multiple grains of orangeyellow chondroite richly scattered through a central seam, associated with minute, steel-grey graphite flakes as well. Ex- Dutch collector Renaud Vochten and accompanied by his data sheet label, overall size about 11x7x5 cm @ 55.00. One only!

COULSONITE- Buena Vista Hills, Pershing Co., Nevada
Known from only two localities in Nevada, coulsonite occurs intergrown with magnetite, with which it is visually indistinguishable from, and may be associated with massive scapolite and other species as well. Originally obtained from Forrest Cureton many years ago and positively ID'ed in these specimens by polished section ore microscopy, sizes range from 2cm to 5cm @ 25.00, 45.00, and 65.00 each.

DEMICHELEITE-(I) & ARGESITE- La Fossa Crater, Vulcano, Lipari, Italy
A pair of extremely rare minerals, with minute black, submetallic micro sparys of demicheleite-(I) sparsely scattered on matrix (EDS showed I>Br>Cl) with scant, pale yellow argesite (NH4)7Bi3Cl16 as well. A unique combination of species, both from the type locality for each. Modest micro potential, specimen measures about 1.5cm across @ 475.00. List alternates!

DIAMOND (3.65 cts)- Mir Mine, Yakutia (Sakha Republic), Russia
A highly unusual, gem-quality clear group of two intergrown diamond octahedrons, measuring just over 1cm across and weighing an impressive 3.65 carats. From one of the largest "holes in the ground" in the world, the Mir Mine was Russia's first major diamond producer. The crystal group has no visble matrix and has cutting potential as well, one of the few gem-quality pieces in our extensive diamond inventory. Ex-David New Collection, priced at 3650.00. Wow!

DYPINGITE- Clear Creek Area, San Benito Co., California
This magnesium carbonate occurs as white to tan opaque small white balls and bottryoidal crusts on greyish serpentinite matrix. The dypingite is occasionally associated with flattened sprays of artinite on some specimens, suggesting these may have originated in the Artinite Pit in this Picacho Peak locality. Fairly good coverage on these typical specimens, sizes from 2cm to 7cm @ 15.00, 25.00, 45.00 and 65.00 each. Old material, ex-Cureton and collected over 20 years ago!

FLORENCITE-(Nd)- Sausalito, Marin Co., California
Rather nondescript, brown and somewhat pulverent florencite-(Nd) described in 1971 by D.J,. Milton et al from this locality. The material is ex-Cureton and offered only as small fragments from about 3mm to nearly 9mm @ 15.00, 30.00 and 55.00 each. Limited availability of this old material!

FLUELLITE- Gold Quarry Mine, Eureka Co., Nevada
These may be the finest known examples of fluellite ever found, and certainly the first find from Nevada about 20 years ago! At this great Carlin Trend locality, fluellite occurs as sharply formed transparent crystals richly scattered on grey chert surfaces, usually as tiny individuals but also as rosettes from 0.5 to 3mm across. Colors range from golden yellow to greenish to pale purple, with color zoned crystals frequently encountered. Numerous associations are known, and most will have micro potential as well. Matrix sizes from 2cm to 8cm @ 15.00, 25.00, 40.00, 60.00 and 75.00 each.

FLUORITE- Rosiclaire, Hardin Co., Illinois
Perhaps one of the most storied localities in the Illinois-Kentucky Fluorspar District, the Rosiclaire District was home to more than a dozen producing mines. Because miners were threatened with termination if caught harvesting specimens, precise localities were often not given for fear of being traced back to the miner involved. These samples were purchased in 1956 from the late Gene Curtiss, who often met the miners in the middle of the night in local cemeteries to exchange minerals for cash. We recently acquired a good stock of these fluorites, typically in some shade of purple in cubic crystals and aggregates largely comprising matrix, some occasionally with calcite druses or other species. Despite the ridiculously high prices charged for this material
today, we are offering specimens at mine-run prices from 4cm to 10cm across for only 10.00, 20.00, 35.00, 50.00 and 75.00 each, depending on quality and size. Old stuff recently brought to market!

HYDROBORACITE- Thompson Mine, nr. Ryan, Inyo Co., California
This unusual borate occurs as slender, white needle-like crystals richly scattered on matrix, some with minor colemanite and possibly other phases. Old material available as either attractive, mounted thumbnails @ 10.00, or as matrix specimens from 3cm to 6cm @ 25.00, 35.00, and 50.00 each. A few foreign localities also available - please inquire.

HYDROZINCITE- Evelyn Mine, Northern Territory, Australia
From a relatively old find, we've located a small number of excellent, micro-crystallized tufts and needles of white hydrozincite richly scattered on matrix, many associated with clear hemimorphite and possibly other minerals from this Pine Creek area deposit. Brilliantly fluorescent, and most with good micro potential as well, sizes from 2cm to 4cm @ 5.00, 12.50 and 20.00 each. We can also supply a small lot of 10 TNs @ just 40.00! Nice!

KOTULSKITE- Oktyabrsky Mine, Talnach, Noril'sk, Russia
A small ore sample about 2.5cm across in a leucite probe mount, accompanied by a pair of SEM images pinpointing the rare mineral kotulskite - Pd(Te,Bi) - in a matrix comprised largely of chalcopyrite with minor pyrrhotite, gold and pentlandite. Full analytical microprobe data is included as well, only one on hand @ 195.00 with full documentation as described.

KRAISSLITE- 1200'L, Sterling Mine, Ogdensburg, New Jersey
Coppery-red to brownish kraisslite forms a micaceous scale that partially covers at least one side of these examples of granular, red willemite, some potentially with minor fibrous white sussexite, franklinite etc. All samples are brightly fluorescent (green) due to the pervasive granular red willemite, with overall sizes from 1.5cm to nearly 8cm across @ only 10.00, 20.00, 30.00, 45.00, 60.00 and 85.00 each, per quality and size.

MALACHITE "Finger Stalactite"- Komoto Open Pit, Kolwezi, Shaba, Zaire
Although the locality is now known as Katanga Province in the Democratic Republic of the Congo, these mounted thumbnail specimens are ex-Scott Williams, these from his extensive holdings purchased some years ago. His original inventory note listed the former "Shaba, Zaire" as the locality, suggesting these were obtained prior to the transition year of 1997. These are stalactitic "fingers", somewhat phallic in habit, comprised of deep green malachite mounted upright in a Perky box. These are 2-2.5cm tall with no discernable matrix, offered at Scott's original price of just 20.00 each. Only a few on hand!

MICROCLINE variety AMAZONITE- Qui-Buc #5 Mi, Florissant, Teller Co Colorado
Another lot from the old thumbnail stock of Scott Williams Mineral Company, a selection of quite fine amazonite crystals, neatly mounted in standard TN boxes. Most samples show excellent blue color and sharp crystal form, a few with subordinate quartz matrix evident. Scott's handwritten label indicated these were from the "Que-Buc #5 Mine" in the Florissant-Crystal Peak area, an apparently small prospect in this prolific area unknown to me and unrecorded in Mindat. Neat specimens, offered at Scott's original prices from years ago at just 25.00 each.

MINGUZZITE- Cape Calamita, Elba, Livorno, Italy
A decidedly ugly mineral, here from the co-type locality, minguzzite is offered as small powdery masses of nondescript yellowish brown powdery material in a small capsule, originally in the extensive stock of the Cureton Mineral Company from many years ago. Formula is K3Fe3+ (C2O4)3*3H2O. Named for mineralogist Carlo Minguzzi, I can't imagine he was happy that his namesake mineral was so bereft of visible charm. Only a few on hand @ 35.00 eaach.

PANSNERITE (IMA 2016-103)- Arsenatnaya Fumerole, Tolbachik, Russia
Russian scientists continue to work on the remarkable number of new species discovered from this Kamchatka volcano, and this particular fumarole has revealed 30 new species to date! Pansnerite occurs as minute, slightly greenish yellow granular crystals, and we offer individual micro crystals mounted on small adhesive stubs. Formula: K3Na3(Fe3+,Al)6(AsO4)8 - orthorhombic, IMA # 2016-103. Author's studied material, only a few samples available @ 150.00 each.

PARGASITE- An Phu Mine, Luc Yen, Yenbai Province, Vietnam
Bright green, stubby columnar masses of attractively colored pargasite to 1cm perched in brilliant white marble matrix. Much of this and similar material has been offered as fluor-cannilloite, but the vast majority of such samples are actually pargasite. Only three colorful samples on hand, overall about 4cm with pleasing, applegreen pargasites therein, @ just 40.00 each. Nice!

PENTAGONITE- Quarry #4, Wagholi, near Poona, India
Brilliant, electric blue radiating crystal sprays of pentagonite in isolated balls to 1cm on matrix. Excellent, attractive specimens, XRD-confirmed, priced at half what the rest of world is charging for unchecked material (that is likely cavansite), these from the actual mining company that first brought them out! All have good micro potential as well, sizes from about 2.5cm to 6cm, priced according to quality at just 25.00, 50.00, 75.00, 100.00 and 125.00 each. Super!

PETALITE- Itinga, Minas Gerais, Brazil
Transparent to translucent clear crystals and aggregates of petalite without matrix, these likely the source of the faceted material seen on the market some years ago. Relatively clean and pure specimens, the larger ones less cloudy and quite transparent, sizes ranging from about 1.2cm up to 3cm tall @ just 25.00, 40.00 and 55.00 each. Gemmy crystals!

PUTORANITE w/ MOOIHOEKITE etc.- Talnach, Norislk, Siberia, Russia
A superbly documented sample of this rare species, offered as 1cm ore sample mounted in a 2.5cm probe mount, accompanied by full quantitative probe data as well as complete XRD output showing admixed mooihoekite! A pair of rare copper-iron sulfides from one of the world's most inhospitable places, only one
documented sample on hand @ 245.00.

PYRITE with FRANCKEITE- 305m Level, Bismark Vein, Siglo XX, Bolivia
An unsual specimen from a very precise location within the famous Siglo Vente Mine in Llallagua, originally from the Reynolds M. Denning collction at Michigan Tech. Denning was a Professor at the University of Michigan who worked and collected in Bolivia during WWII. This sample shows fairly large octahedra and cube modifications of pyrite to 1.5cm comrising matrix, with one edge showing a dull, 3cm aggregate of greyish metallic franckeite. Overall specimen size about 5.5 x 4.5 cm @ 65.00. A precisely-located and historic specimen, but one only!

QUARTZ pseudo @ CALCITE- Rattlesnake Butte, Jackson Co., South Dakota
These are excellent, well-formed scalenohedral calcites from 3cm and getting progressively larger, all in attractive and interesting divergent groups largely replaced by pale greyish-white sandy quartz. Described in the 1920's, early work on this material showed about 15 different species make up the sands, with approximately 37% residual calcite remaining in these weird crystal groups. Neat specimens from about 4cm to 8cm across @ just 15.00, 25.00, 35.00 and 45.00 each.

REBULITE in ORPIMENT- Jiepaiyu Mine, Changde, Hunan, PR China
This rare Tl-Sb-As-S mineral occurs here as tiny, dark grayish black submetallic pods sparsely scattered in brilliant yellow to orange-yellow orpiment matrix, occasionally with minor realgar and potentially other species. Analyzed material and from only the second known occurrence in the world, specimens range from 2cm up to 6cm across at 75.00, 125.00, and 250.00, depending on size and coverage, all with arrows and copies of our confirming analysis.

SCORODITE- Baishiding Mine, Zhuang A.R., PR China
Unusual, glassy blue scorodite crystals and glassy aggregates to 5mm (!!) scattered among pyrite and other sulfides comprising matrix. From the find of about 10 years ago, these are excellent for the species with surprisingly large crystals, many deeply embedded in sulfide matrix. Study under the 'scope will show much color zoning and other mysteries to be solved, with only a few specimens on hand averaging about 4cm @ 95.00 each. List alternates!

SHORTITE- Stauffer Mine, Green River, Wyoming
From the geological formation that hosted the type locality, shortite occurs here as tabular crystals to 1cm embedded in dull mudstone matrix, all showing interesting yellow fluorescence and blue phosphorescence, generally well-scattered with occasional larger aggregates richly scattered through matrix, which is fluorescent as well. The shortite occurs as nearly transparent pale yellow blocky masses, passably attractive fro an uncommon mineral. Sizes from 2cm to 6cm @ 10.00, 25.00, 35.00, and 55.00; a few larger specimens to 13x7cm on hand @ 100.00.

SPERRYLITE- Vermillion Mine, Sudbury, Ontario, Canada
From the Weber-Perloff Collection material purchased some years ago, we have three boxed and mounted samples from this famous locality, each quite different and carefully mounted in a micro box. The first is an exquisite, very sharp tiny single crystal just over 2mm long delicately and expertly balanced on a cactus spine @ 75.00; a larger cubo-octahedral crystal group with minor golden chalcopyrite about twice as large @ 125.00, and a matrix (!!) specimen with multiple crude crystals scattered about a 1.3cm matrix @ 175.00. Only one of each; list alternates!

SPHALERITE and GALENA- Tochibora ore body, Kamioka Mi, Gifu Japan
An unusual "Shiroji-type" skarn ore, here a solid mass of densely intergrown massive sphalerite and predominant galena completely comprising matrix. Skarns often play host to metallic mineral deposits, and this Honshu Island deposit is also the type locality for kamiokite. A modest hand specimen measuring 9x4cm is offered at 45.00.

TENORITE in CHRYSOCOLLA- Chuquicamata, Antofagasta, Chile
A block of copper ore from this prolific locality, here comprised largely of bluish-green chrysocolla with several pods of black tenorite to 2cm wide scattered therein. The piece has several cut faces that reveal a complex banding of several phases. Overall size about 6x4cm at just 30.00. Colorful!

TETRAHEDRITE variety SCHWAZITE- Pueblo District, Harney Co., Oregon
An old specimen of this mercurian variety of tetrahedrite, the ore material described in great detail in a Canadian Mineralogist article in 2001 (Vol. 39, No. 3, pgs 819-830) in which the author's identified a wide range of ore minerals and secondaries from this old and prolific area. This sample is ex-Wintringham and acquired from the old Sunshine Acres School of Mays Landing, NJ, circa 1950s. The piece shows dark greyish masses of Hg-rich tetrahedrite in seams in siliceous matrix, and under the scope, evidence of covellite, trace azurite, filmy chrysocolla and other unidentified phases scattered throughout the sample. Not pretty, but worthy of further study, as Mindat does not list the azurite and other potential secondaries seen in the specimen. Overall size
about 8x6cm @ 55.00.Great locality piece; one only!

TUNGSTENITE- Crevola Quarry, Ossola Valley, Italy
From material acquired in the mid-1970s, these are white marble matrix samples with very tiny, isolated platy grains of greyish-black tungstenite very sparsely scattered in matrix, occasionally with scant, orange-brown phlogopite evident as well. All specimens with arrows to aid in microscopic examination, overall sizes from 2.5cm to 4cm across @ 20.00, 30.00 and 45.00 each.

BOOKS
Natural History of NY- Part III - Mineralogy (1842) Lewis C. Beck
This oversized original 1842 volume contains over 530 pages of crystal drawings, plates, maps and text describing the mineralogy of the State as known at the time. An original edition of Beck's groundbreaking compilation, bound in gold-embossed brown cloth and printed by White & Visscher in Albany in 1842, the cover is worn and torn in several spots but contents are in good condition with minor foxing. This classic work begs to be rebound, originally priced at 350.00, reduced to just 175.00 plus shipping due to condition of the cover. Superb, historical locality data - don't miss this one!

COLLECTIONS
UK MICROMOUNTS- Various Mines, United Kingdom
There are a vast number of mines in the UK that produced numerous secondary minerals suitable for micromounts. In order to make room in our fully-filled warehouse, we offer a dozen different specimens from a wide range of UK mines, all individually labeled and mounted in TN/Micro boxes at just 49.00 per dozen. While there are more dollars to made selling these interesting minerals individually, enjoy this blowout offer while supplies last. Multiples welcomed, and these are sure to please!

GEMS
CORUNDUM (RUBY - HT-GF)- Unspecified locality Madagascar
This are bright red, transparent faceted oval corundums (ie. ruby) that average about 8x6mm and typically weigh around 2 carats each. Like many modern gemstones, we believe these are both heat-treated and leaded glass filled to disguise faults and improve both color and transparency, and we label them as "HT-GF" based onour opinion. That said, they are nonetheless attractive and inexpensive compared to untreated ruby of this color and transparency, with each stone offered at just 35.00 each. Only a few available!

CATALOG 21708 – Volume XLIV, No.8

ALPERSITE- Big Mike Mine, Pershing Co., Nevada
This rare Mg-Cu hydrous sulfate occurs here at the type locality as pale blue to slightly greensih blue crystalline mounds attractively scattered and largely comprising matrix. Minute needles of white pickeringite are evident on most samples, and these have been XRD-confirmed by the author, and resentative XRD data is suplied with each specimen. Cell dimensions were refined using Rietveld analysis. The mineral occurs rarely as an effluorescent here and is infrequently present at the locality, uncovered under only ideal conditions of formation. Ex-Forrest Cureton, surprisingly attractive specimens ranging from about 4cm to 7cm across are offered at just 45.00, 75.00 and 125.00 each.

AZURITE- Concepcion Mine, Catorce, S.L.P., Mexico
Old time specimens from this excellent silver-copper-zinc locality, considered by Panczer as "limited distribution" in reference to the amount of specimen material produced. These were originally purchased in 1964 and are just now seeing the light of day once again! Azurite occurs here as sparkling druses and elongated crystals up to 7mm long(!!), nicely perched in opened seams in a limonitic matrix, some showing partial pseudomorphing to bright green malachite as well. Quite fine, we offer a range of specimens from several flats of this old material, specimen sizes from about 3.5cm to nearly 7cm across, priced according to quality, not size, @ just 10.00, 20.00, 35.00 and a few at 45.00 each. Wonderful in both hand specimens and under the scope as well!

BETAFITE var. CALCIOBETAFITE- Mount Brusa, Luvigliano, Padova, Italy
This uncommon mineral occurs as minute, bright orange glassy micro crystals very sparsely scattered in vugs in sanidine matrix. Approved by the IMA in 1982, it was later discredited in the redefinition of the pyrochlore group minerals in 2010, suggested to be a Ca-dominant betafite since it was Nb-dominant over Ti. Whether it will remain a variety of betafite or another species will depend on future nomenclature changes. These interesting specimens have modest micro potential, and all have pinpointing arrows. Specimens average 2cm @ 65.00 each. Only a few on hand!

CALCITE- nr. Santa Barbara, Curacao, Neth. Antilles
White to pinkish massive calcite matrix with occasional small vugs yielding micro calcites as well. Mildly fluorescent (SW purple-blue), some with minor associated phosphate (predominantly apatite) as well. Very unusual locality material (cactus and salty ocean in the same vista!), about 35 miles off the coast of Venezuela. Be the only kid on the block with an analyzed Curacao calcite; matrix sizes from 2.5cm to 8cm @ 7.50, 15.00 and 30.00 each.

CASSITERITE- Huanuni, Oruro Department, Bolivia
A old lot of excellent cassiterite TNs uncovered from our stock of the Scott Williams collection. The dark brown to nearly black Huanuni specimens show superb, brilliant luster as well as the interesting, blocky crystal form sometimes called a "drill-bit" that displays elongated prism faces terminated with a nicely pointed pyramid. Associations on a few samples are typically elongated quartz crytsals. Obviously older material, specimens quite fine and averaging 2.5cm and mounted in "perky boxes" @ just 30.00 each. Only six available.

CLINOZOISITE var: CLINOTHULITE- Micaville, Yancey Co., North Carolina
Bright pink radiaiting aggregates and masses lightly scattered in white oligoclase matrix, typically associated with minor muscovite and/or quartz. Likely from the Fanny Gouge Mine within the Spruce Pine District, these samples were acquired over fifty years ago. Moderately colorful and representative, specimens range from about 3cm to 8cm across @ 7.50, 15.00, 25.00 and 40.00 each. Neat old stuff!

DIAMOND- Ekati Mine, Lac de Gras, NWT, Canada
From the most significant North American diamond producing deposit, we have several superb single octahedral diamond crystals without matrix, all showing excellent form with hues ranging from pale grey to light tan, most typically with minor carbon inclusions and the larger samples with moderately good transparency. Excellentdiamond specimens, these are offered as follows: 2.15 cts @ 440.00; 2.34 cts @ 615.00; 2.67 cts @ 920.00; 3.31 cts @ 1180.00 and one @ 3.59 cts @ 1270.00; all net priced based on size and clarity; don't miss these!

EPIDOTE-CLINOZOISITE- Peavine Peak, Washoe Co., Nevada
These are TN-sized specimens with dark red, elongated crystalline aggregates well scatteed in quartz. While the literature notes that these have traditionally been labelled as piemontite, our chemical analyses have found that there is no Mn in the samples, suggesting that they are actually somewhere between clinozositite and epidote with an intermediate Fe content, and hence, we have labeled them accordingly as epidote-clinozoisite, but they are clearly NOT piemontite. Each colorful TN-sized specimen is accompanied by a copy of our analytical work @ just 15.00 each, about one-third the cost of the analysis itself!

EUCRYPTITE- Londonderry Quarry, W.A., Australia
Rich massive eucryptite comprising matrix and often intergrown with dull beige feldspar, the eucryptite typically white to very pale pink in color. The species is fluorescent dull red to pinkish (SW UV), and these are old specimens originally obtained by Forrest Cureton in Australia many years ago. Specimen sizes range from about 2cm to 5cm across @ 10.00, 25.00 and 45.00 each.

FERRINATRITE w/ METAVOLTINE etc- Le Cetine Mine, Siena, Tuscany, Italy
This uncommon Na-Fe sulfate mineral occurs here as minute white needle-like micro crystals and aggregates, often intergrown with rozenite and almost always associated with yellowish masses of metavoltine. Only a few specimens available, sizes from 2.5cm to 4cm @ 25.00 and 35.00 each, depending on coverage, not size.

GALENA- East Tennessee Pb-Zn District, Tennessee
An old specimen collected by famous geologist/mineralogist E.W. Heinrich, here as massive galena aggregates richly scattered in off-white, calcite-rich rock matrix. The peice is quite heavy and is accompanied by both Heinrich's label as well as that of the A.E. Seaman Mineral Museum. Overall size about 10x6cm @ 55.00. One!

GETCHELLITE- Getchell Mine, Humboldt Co., Nevada
From the famous South Pit discovery many years ago, getchellite occurs here as deep red, platy to micaceous aggregates lightly scattered in matrix, typically with orpiment, pararealgar and occasionally minor realgar as well. Classic material from the type locality and quite colorful, sizes from 2cm to 7cm @ 15.00, 25.00, 40.00, 55.00 and 75.00 each.

GOLD- Marupa River, Jacareacanga, Para, Brazil
From an extraordinary find, we have a pair of exceptional gold specimens found on the left bank of the river in 2015. Offered here as well-crystallized floaters that display well and are of significant size. These are quite aesthetic, appearing as frothy, crystalline masses, ranging from 3.5cm to 4cm tall, weighing an impressive 36.9g to 53.3g @ 4100.00 and 5950.00 respectively. Crystallized gold is not cheap, but Wow!!!

HAUCHECORNITE- Vermilion Mine, Sudbury, Ontario, Canada
This complex bismuth and antimony bearing nickel sulfide occurs as pale bronze, sparse metallic grains, often intergrown with visually indistinguishable associated chalcopyrite. Probably more common but difficult to recognize, we have small specimens about 1 cm @ 30.00, and a pair of larger samples, ex-Prosper Williams, 6cm @ 150.00 and 11 cm @ 250.00. List alternates!

HETAEROLITE- Esperanza Mine, Lavrion, Greece
Tiny, black dipyramidal crystals of hetaerolite scattered in limonitic vugs, occasionally with tiny needles of pyrolusite in association. Soem samples have weirdly twisted crystals of brownish dolomite as well, with matrix sizes averaging about 3cm across, all with micro potential, at just 40.00 each.

HYDROKENOMICROLITE-3R- Alto do Giz, Parelhas, RG do Norte, Brazil
Extremely tiny, pale greenish yellow to colorless grains (1mm or less) of this exceptionally rare mineral individually mounted on a boxed, adhesive disk. Confirmed optically and by microprobe, these are type locality specimens very competetively priced at just 45.00 each! Rare stuff, the material a valid mineral now considered as a Ba-rich variety from this locality and recently IMA approved from the former parabariomicrolite name to the new mineral in CNMMN proposal 16-C!

HYDROMAGNESITE- Chalk Mountain, Churchill Co., Nevada
Small white botryoids to several millimeters richly scattered over rock matrix, these comprised of tightly packed, radiating clusters and needles of hydromagnesite. Recently XRD-confirmed, these were collected on the west side of Chalk Mountain and were recently uncovered in our warehouse (see Mindat image). Some associatedwith pale blue mcguinnessite, specimen sizes from about 2.5cm to nearly 10cm across @ just 8.00, 15.00, 25.00, 40.00 and 55.00 each. Neat, and all with micro potential as well!

JAMBORITE pseudo @ MILLERITE- Ca' dei Ladri, Emilia Romagna Reg. Italy
Old material from this uncommon locality, here as sparsely scattered, small radiating needles of dark greenish jamborite lying flat in matrix, likely as pseudos after millerite. Only a few specimens on hand, specimen sizes from 2cm to 3.5cm @ 20.00, 35.00 and 50.00 each.

KARNASURTITE-(Ce)- Pegmatite #62, Mt. Karnasurt, Lovozero, Russia
Dull yellowish to tan platy aggregates sparsely scattered in matrix, these from the type locality for the species in the Hackmanite Stock of the #62 pegmatite. Most samples are associated with massive, white natrolite, fluorescent hackmanite, etc. Specimens range from 1cm @ 25.00 to 3cm @ 65.00.

LEISINGITE- Centennial Eureka Mine, Juab Co., Utah
This rare species occurs as minute, bright yellow platy crystals and aggregates very sparsely scattered in drusy quartz vugs. A rare copper-tellurate mineral, and there were fewer than a dozen good specimens available on the worldwide market from the 1992 find. These are the very last of our stock, all micros requiring at least 25x, matrix sizes average about 1cm @ 350.00 each. List alternates!

MEGACYCLITE- Tsentral'nyi Mi, Rasvumchorr, Kola, Russia
An exceptionally rare mineral, here from the second find for the species at Rasvumchorr Mtn in Khibiny. The mineral occurs here as snow-white aggregates and extremely thin veinlets up to several millimeters long, sparsely scattered in and on dark green aegirine aggregates and crystals frozen in matrix. All specimens with pinpointing arrows, overall matrix sizes from 1.5cm to 4cm across @ 85.00, 120.00, 165.00 and 200.00 each.

MEGAWITE (IMA #2009-090)- Lakargi Mt., Kabardino-Balkaria, Russia
This relatively NEW SPECIES occurs as minute inclusions in a complex hydrogrossular-larnite matrix, occasionally with other identified species noted. Superbly documented samples of polished sections about 5mm across in 10mm epoxy mounts, each including a color image and four (4) labelled SEM images that pinpoint and identify the species and its associations. A new CaSnO3 (orthorhombic) mineral in minute, pale yellowish-brown aggregates, IMA #2009-090, co-type material with full probe data, a new member of the perovskite group, only one specimen available @ 245.00.

MELANOVANADINITE- Minasragra, Cerro de Pasco, Peru

A rare mineral from one its more prolific occurrences, granular aggregates of micro masses in full 2cm vials @ 25.00 each, matrix specimens from 1cm to 2cm @ 45.00 and 65.00 each. Ugly stuff but uncommon and from the classic occurrence!

MONTMORILLONITE- Willard District, Pershing Co., Nevada
Relatively pure, greyish white montmorillonite completely comprising these specimens, collected over 30 years ago from the clay deposits found among several tributaries in Coal Canyon. Rich but blandly ugly material, specimens ranging from about 4cm to 8cm across @ just 8.00, 15.00 and 25.00 each.

NACAPHITE- Koashva Mt., Khibiny, Kola, Russia
Small stacked tabular aggregates of white to slightly pinkish nacaphite perched in small pods in a dark green, aegirine-rich rock matrix. Superior to the nearby type locality material, we have only a few samples of this rare phosphate, sizes from several small fragments in a capsule @ 25.00 per vial to matrix pieces to 1cm @ 55.00 each.

NOVACEKITE-II- Animas Mine, Santa Eulalia, Chihuahua, Mexico
Minute, bright yellow platy aggregates of this uncommon uranium mineral lightly scattered on gypsum matrix. Many samples labeled simply as "novacekite" are often novacekite-II, the phase with 10 waters rather than 12, heading towards metanovacekite (8 waters) due to the mineral's well-known loss of water at ambient conditions. Specimens range from about 3cm to 5cm across @ 30.00, 50.00 and 75.00 each, depending on coverage.

OLIVENITE- Black Pine Mine, Granite Co., Montana
From material described in our June, 2012 Mineral News article, we have a small lot of micro green olivenite specimens on hand, typically as zincian olivenite in tiny sheaf-like crystals rarely exceeding 1mm perched in quartz vugs sometimes with associated corroded tetrahedrite and sometimes with other late-stage copperminerals. Specimen sizes range from about 2.5cm to 6cm @ 15.00, 25.00 and 45.00 each, most with modest micro potential as well.

PERTLIKITE with COQUIMBITE- Alcaparrosa Mine, Calama, Atacama, Chile
A fairly rare mineral described about ten years ago, perlikite occurs as pale yellowish to slightly greenish when Zn-rich micro crystal aggregates sparsely scattered on sulfate matrix, here with a nice lavender band of crystalline coquimbite running through throughout a white, krausite-rich matrix. IMA #2005-055, and only a couple samples available, and trimming may expose occasionally associated alcaparrosaite, overall sizes about 4cm @ 155.00. List alternates!

QUARTZ variety AMETHYST- Unyang, Hwanghae-namdo, North Korea
An obscure locality highlights these small, relatively clean single crystals of amethyst, showing good transparency at the pyramidal faces and typically cloudy at the prisms. Recently uncovered from the detritus of the Julius Weber collection, the vintage of these TN-boxed specimens is unknown. Among the few North Korean minerals we have ever offered, crystals range from about 1.3cm to 2cm tall at just 10.00 and 15.00 each. Only a few available; list alternates!

ROOSEVELTITE- Moldava, Dubi, Bohemia, Czech Republic
Minute, dull white, somewhat platy aggregates of this unusual bismuth-arsenate mineral offered as tiny aggregates in a capsule. Named by Herzenberg in 1946 for President Franklin Delano Roosevelt. Old Cureton stock that is strictly reference material for the species, just a few vials available @ 30.00 each. List alternates!

SPHALERITE var "RUBY JACK"- Baxter Springs, Cherokee Co., Kansas
Classic Tri-State sphalerite, here as rich, deep red to nearly black glassy crystals fully scattered on greyish chert matrix, occasionally as darker floater groups comprising matrix. Originally purchased in 1957 (!!) from the famous Tri-State dealer Boodle Lane, these are surley an American mineral classic, with most specimens in the 5cm to 10cm size range @ just 8.00, 15.00, 25.00 and 40.00 each. About 10 flats of this 60 year-old stock!

SPINEL- An Phu Mine, Luc Yen, Yenbai Prov., Vietnam
Deep red to pink octahedral spinel crystals nicely contrasted on and protruding from brilliant white marble matrix, with individual crystals ranging in size from about 1.5mm to 3mm across, with virtually all specimens showing multiple crystals on each matrix sample. The overall specimen sizes average about 6cm across and are very inexpensively priced at just 30.00 each, far below previous stocks!

TUNDRITE-(Ce)- Vostochnyi Mine, Koashva Mt, Khibiny Russia
From a relatively new find, these are likely the finest Tundrite-(Ce) samples to ever come out of Russia, certainly competeing with the best of Mont St. Hilaire and Ilimaussaq specimens. The mineral occurs as pale yellow radiating sprays of acicular crystals in groups to 1cm across lying flat on matrix, typically associated with natrolite, aegirine and lamprophyllite. Overall specimen sizes average up to 4cm across at 125.00 each, certainly among the best of the species. Only four specimens available!

TUNGSTENITE-2H- North of Chase Creek, B.C., Canada
Dull grey metallic masses of the 2H polytype of tungstenite and admixed sulfides scattered in white quartz matrix. Old Cureton material from many years ago, lean specimens range from about 1.5cm to 4cm @ 25.00, 45.00 and 85.00 each. Only a few available from this unreported occurrence!

URANINITE- North Jack Pile Mine, near Laguna, New Mexico
A pair of dark, granular sandstones collected by E. W. Heinrich from the Upper Jurassic Morrison Formation, each moderately radioactive due to included granular uraninite. Frequently associated with coffinite as well, Heinrich noted in 1958 that both the Jack Pile and North Jack Pile were being mined via an open cut, ultimately planning to connect the two deposits into a single operation, located about 6 miles north of Laguna in Cibola County. Many references today simply call the deposit "Jackpile Mine" (one word), ignoring its earlier naming and history. The specimens average about 7x5cm @ 125.00 each.

VANADINITE- Mammoth Mine, Tiger, Pinal Co., Arizona
From an old dealer's stock, we've located a handful of well crystallized vanadinites from this prolific locality, here as small orange-red barrel shaped micro crystals very richly scattered on matrix. Attractive specimens, overall sizes ranges from about 3cm to 6cm across @ just 15.00, 25.00 and 35.00 each. Neat old-timers as either display pieces or can be broken down for prolific micros!

WAKABAYASHILITE- Jas Roux, Hautes Alpes, France
Minute, bright yellow needles and thin laths of this unusual species sparsely scattered on matrix, typically with minor realgar and a variety of odd sulfides. Older samples originally from the BRGM in Paris and analytically confirmed, we have a few on hand, most with modest micro potential, sizes from about 2cm to 4cm @ 20.00, 40.00 and 60.00, priced according to quality not specimen size.

WARDITE- Rapid Creek, Yukon Territory, Canada
Clear to pale greenish-grey tetragonal crystals (some to 1cm !!) and lustrous aggregates scattered on gossan matrix from this excellent locality, more precisely designated as Stoneman Camp. These are not mine-run specimens, but rather are select, well-crystallized wardite specimens from this challenging collecting area, largely accessible by helicopter or small plane only a couple of months of the year. Matrix sizes range from about 3cm to 5cm across, priced according to quality, @ 25.00, 40.00 and 55.00 each. Excellent for the price!

ZOISITE variety TANZANITE- Merelani Hills, Manyara Region, Tanzania
Crudely crystalline purplish-blue zoisite (variety tanzanite) here as crude, matrix-free partial crystals and aggregates showing some striated faces, some with minor graphite. Although relatively translucent to opaque, these are among the most reasonably priced, colorful example of tanzanite we have seen, with specimen sizes ranging from about 2cm to 3cm @ 25.00, 40.00 and 55.00 each. If you prefer gemmy, well formed single crystals, we have those as well at considerably higher cost. Please inquire.

COLLECTIONS

CLASSIC AGATES- POLISHED NODULE HALVES - Worldwide
In the 1960s and 1970s, agate nodules coming from a number localities were of such high quality that they often received specific names to denote their special status among lapidaries and collectors. Today, most of those localities produce little, if any, worthy specimens, and prices for top grade rough can approach $100 a pound for some. We recently acquired from a long-time collector and cutter a very handsome lot of these classic nodules, all expertly cut and polished! The collection includes rare Laguna agates, Coyamito, Agua Nueva and Moctezuma agates from Mexico, excellent banded Botswana from Africa, as well as fine Condor agate from Argentina. These are not slabs, but highly desirable polished nodule halves, and none are heat-treated or dyed. Specimen diameters range from 3.5cm to 5cm across, and a collection of six different localities @ just 95.00 per collection. Every specimen is individually labeled as to precise locality as well, but limit two collections per order, please, as these are in very short supply!

UNITED KINGDOM PYROMORPHITES- 6 Different Mines in the United Kingdom
From a modest aquisition of older micromounts, we have assembled small collections of pyrophite from SIX DIFFERENT MINES in the United Kingdom, including localities in Wales, Scotland and England. All specimens are mounted in 2.5cm clear-top micro boxes and fully labelled as to precise locality, with crystals ranging in color from yellow to green and shades in between. Six different and often unusual UK locality pyromorphite specimens @ just 30.00 per lot. Limited availability - list alternates!

SECONDARY PHOSPHATES- White Elephant Mine, Custer Co., South Dakota
We recently uncovered a flat of secondary phosphates from this locality that were collected years ago by grad students of Willard Roberts at the South Dakota School of Mines. While the locality has produced over forty (40) different species, about half of them occur as well-formed micro crystals of various secondary phosphates. A casual look through the flat disclosed at least ten or more are easily recognizable under the scope in these samples, and trimming would likely yield others as well. To move these out quickly, we are offering two different sized lots of unlabelled samples, sizes from 2.5cm to 5cm for the low price of just 5 specimens for 45.00, or 12 specimens for 100.00. We will include a short checklist of what you may find, but it will be up to you to trim, clean, label and mount these on your own. Limit one lot per order, please!

GEMS

CORDIERITE- Tamil Nadu, IndiaNicely faceted gems of cordierite (variety iolite) show good violet-blue color, as well as the facinating property of trichrosism in which diffeent orientations will show good variation in color from purplish to bluish to greyish within the same stone. Only a few on hand, available as 6mm rounds @ 20.00, and ovals that average about 9x7mm @ 30.00 each.

PETROLOGY SAMPLES

SHONKINITE- Shonkin Sag Iaccolith, Chouteau Co., Montana
From the petrological type locality, these are rather ugly specimens of shonkinite rock that show embedded augite and several other minerals. Shonkinite is a coarse-grained, plutonic igneous rock that typically contains nepheline and alkali feldspars, conventionally defined today as a melanocratic variety of foid syenite. Excellent locality material, acquired in 1974 and likely collected decades earlier, specimens about 5cm @ 35.00 each.

among the most sought-after specimens among collectors. It is reported that the azurites from Chessy were largely mined out by 1845! The piece is ex-Paterson Museum and is accompanied by their rather ratty label, overall size about 3.5cm x 2.5cm @ 225.00.

BABINGTONITE with THOMSONITE- Kouragahana, Shimane Prefecture, Japan
A single specimen comprised of black, highly lustrous micro babingtonite crystals nicely isolated on matrix, associated with several small greyish balls of thomsonite over drusy epidote-encrusted rock. This unusual locality is near the city of Matsue on Honshu Island, and overall specimen size about 4 x 3.5cm @ 30.00. One only, and with modest micro potential as well!

BARICITE- Rapid Creek, Yukon Territory, Canada
From an old hoard, thick micaceous masses of pale "metallic blue" baricite richly comprising matrix. Type locality material, obtained in the 1970s after the species was first described, sizes from single 1cm plates @ 15.00 to larger 2cm to 5cm matrix specimens of high purity @ 25.00, 45.00 and 65.00 each.

Only a few massive samples on hand, sizes from about 2.5cm to 8cm across @ 5.00, 10.00, 20.00 and 35.00 each. One large crystal section about 12x9x7cm on hand @ 100.00.

BETA-ROSELITE with ERYTHRITE- Bou Azzer, Tazenakht, Morocco
An excellent micro specimen, ex-Lou Perloff/Julius Weber collection, nicely mounted in a 2.5cm micro box and showing richly scattered, divergent deep purple platy crystals of erythrite, with a columnar group of lighter pink beta-roselite crystals perched amount the erythrite blades. The piece measures about 2cm
across and is a handsome example of a great association of these two cobalt-rich arsenates. Only one available @ 65.00. Very attractive under the scope!

BRINDLEYITE- Victorio, Luna Co., New Mexico
Rather ugly greenish to brown masses of this rarely recognized mineral, a nickel-rich member of the kaolinite-serpentine group. We have brindleyite as small masses and flakes packed into capsules, varying from tiny aggregates slightly masses, at 35.00 per capsule. Ex-Dr. Sidney Williams, the late mineralogist and manager at Phelps-Dodge's Research Laboratory who described many rare species during his career.

CALCITE (Rare Scepter)- St. Andreasberg, Harz Mts., Germany
A highly unusual crystal from this historic locality, a sharp rhombohedral crystal forms the base for a steeplelike scepter growth comprised of several joined and elongated prisms. A similar sample is pictured in Mindat (ex-Kay Robertson Collection and noted as from an 1800's find). This sample shows a distinctive, rosybrown hue at its core, and it nicely translucent. It also displays a pleasing, dull red fluorescent response as well, under both SW and LW UV. The sample is ex-E.W. Heinrich, famous geologist and mineralogist, and is accompanied by his label. Overall size of this truly superb thumbnail is about 2.5 x 1.5 cm @ 150.00. A highly unusual and excellent TN!

CALEDONITE with LINARITE- Los Azules, Zapallar, Copiapo, Chile
A fairly uncommon Pb-Cu-carbonate-sulfate mineral, the caledonite occurs here as delicate, pale sea-blue micro crystals and aggregates scattered in seams and vugs, associated with striking, dark purplish-blue linarite and potentially other phases in pale rock matrix.

Translucent greyish masses of gehlenite intimately intergrown with merwinite and comprising matrix, occasionally with minor greenish vesuvianite as well. An old US locality for the mineral, rich, massive specimens from 3cm to 6cm across @ just 10.00, 20.00, and 35.00 each.

HEMATITE- Taouzm, Er Rachidia Province, Morocco
Interesting, black botryoids of hematite comprising matrix, the top surfaces being quite lustrous, and the sides of the specimens showing the radiating structure of the mineral in cross section. Fairly attractive and from a locality that started to produce specimen material less than ten years ago. Samples average about 4.5cm across at just 15.00 each.

HEULANDITE-Ca with STILBITE-Ca- Vaijapur, Aurangabad, Maharashtra, India
A recently acquired lot of attractive, pale orange-tan heulandite-Ca as tiny coffin-shaped crystals, very richly scattered over weirdly convoluted matrix, associated with similar colored stilbite crystals and larger bowties of paler stilbite on every specimen. Attractive, analytically confirmed (copy of our EDS supplied) specimens that are quite showy, specimens ranging in size from about 5cm to 15cm across @ just 25.00, 50.00, 75.00, 100.00 and 150.00 each depending on size and aesthetics. Great stuff!

JAMESONITE- Sombrerete, Zacatecas, Mexico
Superb, thick metallic rods of stibnite-like crystals of jamesonite nicely scattered in/on matrix with well crystallized pyrite. From the original 1975 find, these modern classics are exceptional for the species, with overall sizes from 3cm to 6cm @ just 15.00, 25.00 and 45.00.

KENTROLITE- Langban, Varmland, Sweden
Dark reddish black granular masses of this rare lead silicate, richly distributed through a matrix containing biotite, variety manganophyllite, minor calcite, and possibly magnetoplumbite. Representative, and difficult to obtain, these are old Cureton stock samples. Sizesfrom 3cm to 8cm @ 35.00, 50.00, 80.00 and 100.00.

KETTNERITE- Three Muskateers Mine, Mohave Co., Arizona

LATRAPPITE- La Trappe, Oka, Quebec, Canada
Minute, pseudocubic black crystal sections and aggregates of submetallic latrappite sparsely scattered and embedded in carbonatite matrix. Type locality material for this niobium analog of perovskite. Matrix sizes from 1.5cm to 4cm @ 10.00, 20.00, and 35.00 each.

MARCASITE- Cap Blanc-Nex, Pas-de-Calais, France
Solid nodules of marcasite without matrix, occasionally with intimately intergrown minor pyrite that often contributes better stability to these odd ball0like structures. Matrix free, nodules sizes range from about 2cm to 4.5 cm acrss @ 15.00, 30.00 and 45.00 each. List alternates!

META-AUTUNITE- Apex Mine, Lander Co., Nevada
This hydrated calcium-uranium-phosphate occurs here as small (1-1.5mm) pale green platy crystals lightly scattered on dark rock matrix. The specimens will also yield decent micromounts, as the crystals show sharp tetragonal form and contrast nicely against the matrix. Distinguishable from the commonly associated metatorbernite by its fluorescent response under SW UV. Specimens range from 4cm to 12 cm across, @ just 10.00, 20.00, 35.00, 55.00 and 75.00 each for the largest.

MOLYBDOFORNACITE- Alice Mine, Goodsprings, Clark Co., Nevada
Excellent micro crystals of olive green molybdofornacite lightly scattered on matrix, occasionally associated with a wide range of other species, mostly typically hemimorphite, rosasite, cerussite and others. A moderately rare mineral in well-formed, elongated tiny crystals from the Yellow Pine Extension, the mineral has been EDSconfirmed for Mo>Cr content, and a copy of our analytical work accompanies each specimen. (We have found no fornacite thus far, and some earlier reports of the mineral at the locality may have been in error due to overlapping EDS peaks of Pb and Mo which an inexperienced operator might miss!). Fine micro material, specimens range from about 2cm to nearly 6cm across @ just 15.00, 25.00, 40.00 and 65.00 each priced according to quality.

NATROLITE- Upper New Street, Paterson, Passaic Co., New Jersey
Thin, needle-like sprays and tufts of white natrolite well-scattered on basaltic matrix, some associated with prehnite, calcite etc. Old material collected many years ago from this prolific New Jersey locality, now sitting under a housing development. Specimens range from about 2.5cm to 5cm across @ just 7.50, 15.00 and 25.00 each.

OLIGOCLASE- Dordal, near Bamle, Norway
Salmon to pink colored grains of "sunstone", as oligoclase is referred to at times, to several cm occur in igneous quartz and biotite bearing matrix. The characteristic schiller effect is evident in many of these pieces; old Claus Hedegaard specimens, sizes range from 3 to 6cm @ 12.50, 20.00, and 35.00 each.

POTASSIC-MAGNESIO-FLUORO-ARFVEDSONITE- Hgwy 366, Val-des-Monts, Quebec, Canada
Perhaps one of the longest species names in mineralogy, this amphibole was originally described in 1985 from here, the type locality. It occurs as crude, small bluish-black aggregates scattered in matrix, often with somewhat corroded microcline overlaying coarse gnessic matrix, and potentially other rock-forming minerals. Specimens range from 4cm to 8cm across @ just 20.00, 35.00, 55.00 and 75.00 each, but this is ugly stuff!

POTASSIUM ALUM- Silver Peak, nr. Alum, Esmeralda Co Nevada
Excellent, pure columnar masses of colorless, transparent, ice-like potassium alum with little or no matrix. XRDconfirmed material, fine vitreous masses from 3cm up to exceptional 7cm cabinet specimens, priced @ only 10.00, 20.00, and 35.00 each.

PYRITE- Homestake Mine, Lead, Lawrence Co., South Dakota
From this famous gold producing mine that reached a depth of almost 7500 feet (2300 meters), we have uncovered a small lot of very brilliant cubic pryites forming thumbnail groups of both isolated and intergrown crystals, occasionally with minor quartz. Small but quite attractive TNs from about 1.5cm to 2.5cm @ just 8.50 and 15.00 each, also suitable for splendid micromounts!

RHODONITE- Cummington, Hampshire Co., Massachusetts
A fairly old specimen of deep pink, densely aggregated rhodonite largely comprising matrix, accompanied by a crusty and brittle label from Alvan G. Barras (b. 1868) who apparently dealt in minerals from his home in Lithia Massachusetts. The specimen is quite colorful and is bound on two sides by black Mn-oxides, nicely setting off the deep pink core. An old, classic locality with a rare label, overall size about 9x6cm @ 45.00. List alternates!

RUBICLINE- Mt. Vasin-Myl'k, Voron'i Tundry, Russia
Another rare and interesting mineral from the Kola Peninsula, here as small phenocrysts in a complex feldspar and pollucite assemblage. From only the second reported locality for this rubidium-dominant feldspar (and the first of two Rb-dominant minerals known), this is a 2cm polished probe mount, accompanied by one large-format SEMimage and full WDS chemistry and empirical formulae! Only one specimen available with superb documentation, priced considerably lower than the initial find about ten years ago @ just 225.00 each. List alternates!

SAPONITE var: AQUACREPTITE- unspecified locality in Peru
A mineralogical nomenclature oddity, the name "aquacreptite" had variously been used to label both a ferroan antigorite and a hydrated talc, now generally believed to be a Fe-rich saponite. This is a small 3cm pale brown nodule showing a distinct layed banding and smooth, greasy surface with ill-defined conchoidal fracture. The accompanying Scott Williams label suggests a composition near Mg4Fe3+2Si6O19*8H2O, with some Al2O3 present, but the analytical technique is unknown and results are not a clear match for a specific phase, suggesting a mixture. Many well known Peru localities are rich in talc, kaolinites or smectites, so this one will remain an enigma. Only only available, with Williams labels, @ 25.00.

SATTERLYITE- Big Fish River, Yukon Territory, Canada
Greenish brown, somewhat glassy radiating aggregates of this unusual phosphate species scattered in small nodular matrix from this prolific locality. Only a few specimens available, priced according to overall richness, from 2cm to 3cm @ 45.00, 60.00 and 75.00 each.

SCHAFERITE- Arsenatnaya fumerole, Tolbachik, Russia
Another extraordinary find from this Kamchatka volcano, the mineral occurs as bright yellow-orange spherical aggregates forming attractive clusters up to 5mm (!!) across. Discovered in 1997 at Eifel, this occurrence of schaferite from the second scoria cone of the Great Tolbachik Fissure Eruption is far superior to the type locality material, much like the previously offered nichenichite crystals from our previous list. Only three specimens available, sizes average 2.5cm to 3cm across @ 195.00 each. List alternates!

SPURRITE (lilac!)- Fuka, Bicchu-cho, Okayama Pref., Japan
Although a prolific mineral here, at Crestmore, and elsewhere, these are quite interesting in that the spurrite is a wonderful lilac-purple color and comprises much of teh entire matrix of each specimen, occasionally with subordinate amounts of colorless calcite and/or wollastonite. Neat, colorful stuff, specimens from about 3.5cm to 5cm across @ just 35.00 and 45.00 each.

SULFUR (NATIVE)- unspecifed locality in Louisiana
Bright yellow partial crystals and aggregates of native sulfur to 1cm are well-scattered in a sedimentary rock matrix, filling exposed seams that are shared by nicely fluorescent, oddly-zones, micro calcite crystals. The calcite is quite fluorescent (blue-white) under both LW and SW UV, and there are apparently other unidentified species in the sample as well that provide additional color under UV. The piece is ex-E.W. Heinrich, famous mineralogist and geologist, and is accompanied by his label. Overall size is 10x7x5cm with good coverage @ just 55.00 for this colorful Louisiana specimen. One only; list alternates!

THOMSONITE-Sr- Mt. Rasvumchorr, Khibiny, Kola, Russia
This rare zeolite species described in 2000 occurs as minute radiating "brushes" of crystalline groups to 1cm nicely scattered in veinlets and exposed seams on matrix. Formula: (Sr,Ca)2Na[Al5Si5O20]*6-7H2O. Type locality material with some micro potential, and only one of three known localities in the world for this rare Sr-dominant zeolite. Author's material; sizes from 1.5cm to 3.5cm @ 85.00, 120.00 and 150.00 each.URALOLITE- Boevskoye Dep., nr.Kamensk, Ural, Russia This rare Ca-Be-phosphate occurs as minute needle-like aggregates perched in matrix. These are author's material from the original find at the type locality, available as minute fragments with modest micro potential in a capsule @ just 30.00 each.

VANDENBRANDEITE- Musonoi Extension, Katanga(Shaba), Dem Rep Congo
A selection of half a dozen excellent vandenbrandeite specimens, most from the Vandall King uranium collection, here showing well formed, dark greenish black vandenbrandeite crystals to several millimeters isolated and in small groups on uranium-rich, digenite ore matrix, often associated with other uranium minerals such as kasolite, cuprosklodowskite etc.. Fine for the species from this prolific (formerly Zaire) locality, specimens from 2cm to 6cm priced according to quality @ 50.00, 75.00, 100.00 and 150.00 each.

WHEWELLITE on CALCITE- Elk Creek, Meade Co., South Dakota
Extraordinarily large crystals and complex, reticulated aggregates of whewellite perched on brownish, botryoidal calcite matrix, occasionally with yellow calcite points and druses as well! We recently acquired a significant lot of about a dozen high-quality samples from a private mining venture, and these are clearly the best and largest we have ever seen! The mineral ranges from elongated and flattened, crudely etched and reticulated beige to white aggregates that extend from 4cm(!!!) and up, o large, blocky plates of sharper single crystals with minor yellow transparency! Quite incredible for the species, these were recently featured in a short Mineral News article (August, 2017), and a couple are pictured in Mindat as well. Certainly the "Best of Species", specimens range in size from about 6cm to a monster 18cm sample, priced according to whewellite quality, at 300.00, 500.00, 750.00, 1000.00, 2000.00 and 3000.00. These are brilliantly fluorescent at all wavelengths and phosphorescent with some color zoning, too! Second to none, we believe!

WIDGIEMOOLTHALITE- Widgie 132 N Mine, Widgiemooltha, Australia
This rare species occurs as vitreous micro green, glassy crystals and crystalline aggregates in thin gaspeite seams in matrix. A rare one-locality species from the original Westaus Mineral Museum find, sizes from 1.5cm to 2cm @ 100.00 and 125.00, depending on quality/coverage.

WODGINITE var: TANTALOWODGINITE- Veshnyakovskoye, Irkutsk, Siberia, Russia
This uncommon species was originally submitted and approved as tantalowodginite (IMA#2000-026), but then subsequently discredited. It occurs here as small (~1mm) dark brownish grains without matrix, obtained by a Russian scientist from the Elash stream beds! An interesting occurrence, once a member of the ever-expanding wodginite group @ just 20.00 each.

ZIRCON on SIDERITE- Mont St. Hilaire, Quebec, Canada
A rather aesthetic thumbnail specimen showing several greenish-tan intergrown rhombic crystals of siderite to nearly 1cm each comprising the host matrix for a euhedral, brownish tetragonal 1cm zircon crystal that sits perched among the siderites, showing perfect faces and form on all exposed surfaces! The rear of the specimen is filled with micro white, tabular albite crystals, and the specimen is carefully mounted on a clear leucite square in an upright position. The piece is pictured on Mindat.org; quite attractive, well formed, overall size about 2.5x2cm @ 75.00. One only!

FLUORITE w/ CELESTINE- Clay Center, Ottawa Co., Ohio
From the H.E. Moore collection, an older specimen comprised of honey-brown(!!) fluorite cubes to 4mm richly scattered across both top and bottom of a limestone matrix, accompanied by several white, tabular crystals of celestine to 2.5cm long. Moore's label indicates the piece was acquired circa 1967, and a small adhered label is also attached from a predecessor collector. The first time I missed a specimen ID on my Mineralogy 101 course at CCNY back in the 1960s, it was a similarly colored brown fluorite that tripped me up! The piece is brilliantly fluorescent (bight creamy yellow) under both LW and SW UV! Specimen size about 7x6cm @ 65.00. Moderately attractive old timer!

FLUORWAVELLITE (IMA 2015-077)- Willard Mine, Pershing Co., Nevada

HALITE (bicolor)- Herringen, Werra Valley, Hesse, Germany
Likely from the famous Wintersahll Potash Works, these interesting halites are essentially clear and transparent to translucent, but all showing an interesting purplish-blue zoning. Like the New Mexican material, it is believed that radiation exposure is responsible for the color variation seen in these specimens. Old Cureton stock, specimens average about 4cm across @ just 20.00 each.

HEDYPHANE in CALCITE (FL)- Vrancice, nr. Pribram, Bohemia, Czech Republic
Dull tan to brownish masses of hedypahne to a few millimeters sparsely scattered in matrix, overwhelmed by the brilliantly fluorescent (redish orange SW UV) calcite embedded in the matrix. This locality has produced many interesting species, and sulfides such as chalcocite, stromeyerite etc. may be found here as well. These old specimens are generously sized from about 4cm to 6cm across @ just 20.00, 30.00 and 45.00 each.

JOSEITE-B- Glaicer Gulch, nr. Smithers, B.C., Canada
Grey metallic masses of this unusual Bi-Te-S mineral scattered in matrix, occasionally associated with minor tetradymite or other phases. Type locality material, described prior to the IMA's founding and currently a valid mineral, but questioned as a possible Te-rich ikunolite or possibly other phases. Collected in 1963, a few samples available from 2cm to 8cm across @ 20.00, 45.00, 70.00 and 95.00 each.

LOPARITE-(Ce)- Lovozero Massif, Kola Peninsula, Russia
Black granular masses to 5mm across very richly scattered in matrix and richly comprising these specimens. According to I.V. Pekov, it is likely that perovskites described as early as the 1890s from here were very likely loparite-(Ce), not formally described until 1921. Originally obtained from the Fersman Museum in the 1970s, wehave a half dozen samples that average about 4cm across @ just 40.00 each. Tiny single crystals about 0.5mm across are also on hand – please inquire.

MARCASITE- Tri-State District, U.S.A.
Solid nodules of marcasite without matrix, occasionally with intimately intergrown minor pyrite that often contributes better stability to these odd ball-like structures. Matrix free, nodules sizes range from about 2cm to 4.5 cm acrss @ 15.00, 30.00 and 45.00 each. List alternates!

MCGUINNESSITE- Chalk Mountain, Churchill Co., Nevada
Collected many years ago from the west side of Chalk Mountain, we were among the first to offer mcguinnessite from Chalk Mountain as new locality for the species back in the early 1990s. The mineral occurs here as bright blue botryoidal knobs and tiny radiating balls scattered on dark rock matrix, making fine micros and colorful, larger specimens, occasionally with massive magnetite and a variety of white Mg-carbonate phases. These have good coverage and are quite attractive, overall matrix sizes from 2cm to 5cm @ just 7.50, 15.00, and 25.00 each; a few larger 8cm to 10cm @ 55.00, and a monster museumm specimen about 25x10cm @ 250.00! Nice material!

MERELANIITE (IMA 2016-042)- Merelani Hills, Manyara Region, Tanzania
This NEW SPECIES occurs as micro, cylindrical whiskers of dark grey metallic needles, here lightly embedded in transparent calcite cleavages, occasionally with flakes of graphite and/or other phases. Formula: Mo4Pb4VSbS - triclinic, IMA # 2016-042, a new member of the cylindrite group. Recently dubbed the New Mineral of the Year, viewing at 10x easily shows the whiskers that reach up to several millimeters in these samples! Matrix sizes average about 1cm @ 135.00 each.

NEKOITE- Iron Cap Mine, Graham Co., Arizona
A locality known for its odd suite of minerals, nekoite occurs here as bright white to stained tan botryoidal coatings and aggregates of acicular divergent crystal sprays, occasionally to more massive pearly crystalline aggregates scattered on massive johannsenite. XRD confirmed material with modest micro potential as well, sizes from about 3cm to 6cm rich samples @ 25.00, 40.00 and 75.00 each; superior to the more massive California material seen in most collections!

NICKENICHITE- Arsenatnaya Fumerole, Tolbachik, Russia
A highly unusual occurrence for this rare species, here as superb, electric blue micro crystals to 1mm scattered on vuggy basalt scoria from this famous Kamchatka volcano! Minor hematite and orthoclase may be present, but the violet-blue crystals, formed on fumarolic gas-altered scoria, are certainly the best in the world, and far superior to the type (and only other reported locality) material from Germany. Quite exceptional under the scope, specimens from about 2cm to 4cm across priced according to quality @ 150.00, 200.00 and 250.00 each. Only a few available of this world-class complex copper-rich arsenate micro mineral!!

OKRUSCHITE (IMA 2013-097)- Fuchs Quarry, Hartkoppe, Sailauf, Germany
This relatively new rare mineral occurs as minute white to slightly yellowish monoclinic micro crystals scattered in exposed seams and vugs in matrix. Formula: Ca2Mn2+5Be4)AsO4)6(OH04*6H2O - IMA # 2013-097, a member of the roscherite group and its arsenate analog. We have acquired one small sample with a pinpointing arrow, author's material and a portion of the holotype, about 1.4cm across @ 295.00. One only!

OLIGOCLASE variety SUNSTONE- Tvedestraud, Aust-Agder, Norway
A neat "sunstone" specimen with a long provenance that extends from Ward's Natural Science, to the Michigna College of Mines (circa 1927) and to the A.E. Seaman Mineral Museum, with the three individual labels provided. The sample shows deep pinkish-orange oligoclase that exhibits good shimmer across heavily striated, crude crystal faces when positioned at the appropriate angle! With some minor dark mica also present, this is a good example of this interesting feldspar, overall size about 6x5cm @ 60.00.

PEKOVITE- Dara-i-Pioz, Alaiskii Range, Tadjikistan
This rare species occurs as minute colorless grains in matrix, these in prepared 2cm probe mounts and accompanied by at least one SEM image and an X-ray spectra.

It occurs as nearly monomineralic masses of dark greenish grey, coarsely prismatic skarn rock largely comprising matrix. Formula: (K,Na)Ca2(Fe2+,Mg)4Fe3+[Si6Al2O22](Cl,OH02. Author's neotype material from the type locality for the species, specimens average about 1.2cm @ 115.00 each. One of only two known Cl-rich amphiboles found in nature to date!!

RHODOCHROSITE- Wuzhou Prefecture, Guangxi Zhuang, PR China
Neat thumbnail specimens of bright pink, opaque rhodochrosite masses and partial rhombic crystals in matrix, appearing much like old Silverton material with associated quartz and sulfides scattered about the underlying matrix. Colorful and relatively inexpensive, sizes average 2.5-3cm at just 15.00 each.

RHODONITE- Franklin, Sussex Co., New Jersey
An old timer acquired in the 1950s by Howard E. Moore, here as a stout, dull pink rhodonite crystal about 4cm wide and 3cm tall partially embedded in massive franklinite/calcite/willemite matrix, with a lesser partial crystal of rhodonite also evident.

TODOROKITE on COLEMANITE- 20 Mule Canyon, Inyo Co., California
Minute black aggregates of dusty todorokite lying on the surface and lightly included in drusy colemanite crystals comprising matrix. An interesting association and not bad looking, nicely crystallized matrix sizes from 5cm to 12cm @ 45.00, 75.00 and 125.00 each. Old material collected over 20 years ago!

WODGINITE- McAllister Pegmatite, Coosa County, Alabama
Small black rounded aggregates of wodginite relatively free of matrix, some with minor mica but quite pure, offered as numerous granular masses in a small vial. Old Cureton stock originally obtained from the late Eugene Foord atthe USGS, one of the authors of the Canadian Mineralogist article (1989, Vol. 27), and a first reported occurrence for the state (misspelled on Mindat as "McCallister"). Average weight about half a gram in each vial @ just 20.00 per vial; author's studied material.

ZIRCON- Tambani Area, Blantyre District, Malawi
Analyzed single crystals of medium brown zircon without matrix, most showing good crystal faces on several sides, most often with a variety of tetragonal forms. Crystals range from about 9mm to 2.5cm, priced individually at 10.00, 15.00 and 25.00 each, all accompanied by our representative EDS spectra, the larger crystals typically more crude in habit. Inquire for bulk quantities useful for research.

Crudely crystallized andorite masses showing interesting etched surfaces or striated aggregates richly comprising matrix, often intergrown with stannite or other phases. Smaller samples in TN boxes, these average 1.0cm to 1.3cm long and are priced at just 20.00 each, a few larger 2.5-3cm @ 45.00 each.

ARANGASITE (TL)- Alyaskitovoe Depsoit, Ust'Nera, Yak. Russia
This relatively new Siberian raroity is ofered here as pure, dull silky white aggregates with little or no matrix. Type locality    material for this hydrous Al-F phosphate-sulfate mineral has seen little distribution since its IMA approval in 2012, and these  are perhaps the only specimens available from this single-locality species. Specimens range from about 1.4cm to 2cm long @ 150.00 and 200.00 each. Only a few on hand!

BERAUNITE- Three Oak Gap, Polk Co., Arkansas
An excellent specimen comprised of deep red-brown beraunite richly scattered on matrix, certainly one of the better pieces we have seen from the locality. The platy crystals are best viewed under the scope, but they are so prolific that the sample nicely sports the red color across much of the surface of this interesting hand specimen, nicely associated with black goethite that forms a thin, striking layer over a gritty white matrix. About 8x5cm @ just 65.00.

BERZELIITE- Arsenatnaya Fumerole, Tolbachik, Kam Russia
An unusual occurrence of this uncommon mineral better known from Langban, here as surprisingly rich, micro aggregates of pale yellow-orange berzeliite crystals intimately intergrown among colorless anhydrite crusts. Coverage is quite good on the few samples we have, and these could easily be broken down to yield multiple micros if desired. Matrix sizes are in the 3cm-4cm range @ 125.00 each.

CHALCOPYRITE etc.- Fletcher Mine, Reynolds Co., Missouri
An excellent Viburnum Trend specimen, here as wonderfully iridescent balls of multicolored chalcopyrite richly scattered across the top of a heavy sulfide matrix. There is obvious quartz, calcite, pyrite and marcasite present in this Upper Cambrian sample as well, overall size about 11x7x5cm @ 125.00. Nice!

CINNABAR on DOLOMITE- Tongren, Guizhou Province, PR China
Rather colorful specimens showing bright red cinnabar crystalline aggregates and partial crystals lightly scattered on brilliant white dolomite crystals, some with minor calcite and/or underlying rock matrix.

Excellent micro crystals of isolated, apple-green calcian duftite scattered on vuggy matrix, most sitting on micro quartz crystals and occasionally with other secondary minerals such as cuprian adamite. Collected over 20 years ago, superb for the species with fine micro potential, matrix sizes average 2.5cm @ just 12.50 each. Quite attractive under the scope!

FERSMITE- Dark Star Claim, Alta, Ravalli Co., Montana
Excellent, dark brown to nearly black vitreous masses of fersmite well-scattered in quartz matrix. Originally collected by Bart Cannon (cannonite) in 1973, this often-overlooked mineral was the second one named after the founder of the Fersman Museum in Moscow, A.E. Fersman. A few TN specimens available @ 25.00 each.

GALENA with SPHALERITE etc.- Madan, Rhodope Mountains, Bulgaria
A rather nice specimen comprised of tiny, nearly black sphalerite crystals well scattered amoung larger, silvery metallic galena cubes to 7mm richly covering the entire matrix of this old classic. The piece is accompanied by a Bulgarian museum label, and the specimen sits flat with several hillocks and waves of crystals. A neat galena specimen with typical associated species, overall size about 13x11 cm at just 135.00.

GASPEITE- Carr Boyd Mine, Western Australia, Australia
Rich foamy crusts of yellow green gaspeite fill seams and cavities in a reddish limonitic matrix. Some samples show good botryoidal development and excellent color contrast, old material from Westaus Mineral Museum, sizes from about 2cm to 6cm across @ 20.00, 35.00, and 50.00 each.
GOLD- La Campania Mine, Sierra Gorda, Chile
Tiny micro aggregates of native gold sparsely scattered on rock matrix, these suitable as micro reference specimens from this prolific locality. All will require some magnification to appreciate, some with minor atacamite, only a few small TNs on hand, averaging 1.5cm, @ just 25.00 each. One larger but still Au-lean matrix atacamite sample about 4x2cm @ 65.00.

GYPSUM- Lockport, Niagra Co., New York
An older specimen, ex-St. Lawrenece University mineral collection and accompanied by their label, comprised of transparent to translucent crystalline gypsum in a complex intergrowth of crude crystals, also with a white drusy coating of dolomite and bladed calcite)?) as well. A neat specimen that displays well due t its brilliant white/clear combination, overall size about 8x6cm @  just 35.00. One only!

JUANITAITE- Gold Hill Mine, Tooele Co., Utah
This relatively rare species occurs as small, yellow-green micro rosettes and druses sparsely scattered in vugs and exposed seams on matrix, some associated with needle-like blue connellite, or fine tyrolite, or occasionally other species. Most of this material was collected on the 150 level over 20 years ago and was subsequently named for its discoverer, the late Juanita Curtis. Modest micro potential as well, matrix sizes from about 2cm to nearly 6cm @ just 40.00, 65.00, 85.00 and 100.00 each, depending on quality/size.

KUKSITE- Black Pine Mine, Granite Co., Montana
One of the very rare minerals at this prolific locality, kuksite occurs here as very tiny, pale green stacked plates and
aggregates very sparsely scattered in quartz matrix. Each sample is accompanied by its own EDS spectra as well as a color image to   help pinpoint the mineral. Small stuff, will require 40x, but nicely documented in these thumbnail sized specimens that average about 2.5cm overall @ 150.00 each. List alternates!

LOPARITE-(Ce)- Lagendalen, Larvik, Vestfold, Norway
Brownish black, submetallic masses of loparite-(Ce) to 5mm scattered in feldspar matrix, typically with minor aegirine, possible lorenzenite, analcime pinkish eudialite etc. Old material and only a few specimens on hand that average 5cm across @ 55.00 each.

MILLERITE- Halls Gap, Lincoln Co., Kentucky
Small geodes and sections containing tiny  fibrous needles of brilliant, elongated brassy millerite. Once a featured article in Mineralogical Record in 1997, these are old specimens collected nearly 50 years ago, most with good micro potential as well, some with micro pyrite etc. Sizes range from about 1.5cm to nearly 4cm across @  20.00, 30.00, 45.00 and 60.00 each, depending on coverage and quality. We have a few exceptional samples as well at    100.00 each. A classic US locality!

MUSCOVITE (Ball Peen Mica)- Fillow Quarry, Branchville, Connecticut
A pair of large, old specimens showing the classic "ball peen" habit of muscovite so well known from this classic locality, sometimes called "margarodite" in the distant past. Specimen #1 is a 14x10x10cm monster that perfectly displays the contact between the thick band of tan spodumene and white quartz pegmatite, with rather small pods of ball peen mica to a few mm scattered about the top of the piece, offered at just 55.00. Specimen #2 is a large, 16x12x10cm pegmatite sample in which the top surface shows numerous, large curved balls of the mica fully  covering and densely intergrown, larger and as fine as the piece donated to Yale by Dana and Brush and pictured on Mindat.org, a classic example of the habit @ 85.00. Excellent!

NELENITE- Huanggang Mine, Chifeng, I. Mongolia China
From a relatively recent find several years ago, this rare mineral occurs here as micro hexagonal plates that are typically stacked in minute, somewhat globular aggregates nicely perched on white, rhombic cleavages of calcite matrix. Identification has been confirmed by chemistry, XRD and Raman, and a copy of the original Raman spectra is included with each sample. Coverage is obvious to the naked eye and will also yield decent micromounts if trimmed further. Specimens range in size from about 1 cm to nearly 4cm @ just 20.00, 35.00, 55.00 and 85.00 each, priced according to coverage, and from one of only a handful of known localities for the species.

ORTHOSERPIERITE- Vezzani Mine, Corsica, France
Bright bluish-green platy masses and aggregates of this unusual but colorful mineral comprising small, crusty matrix samples. Once thought to be devilline, these small but brightly hued samples are from an interesting locality, offered as numerous tiny fragments in a capsule @ 10.00 or as 1cm small TNs @ 17.50 each.

OZEROVAITE- Second Scoria Cone, Tolbachik, Kam. Russia
This NEW SPECIES occurs as minute (<0.3mm) red to reddish-yellow single grains mounted on an adhesive stub, typically with minute amounts of transparent, colorless aphithitalite as well. IMA approved (2016-019), formula: Na2KAl3(AsO4)4 - orthorhombic. An extremely rare arsenate from the type locality on the Northern Breakthrough of this famopus Kamchatka volcano. Only a few tiny grains available @ 145.00 each.

PEROVSKITE var: KNOPITE- Langorsholmen, Alno, Medelpad, Sweden
Small black masses of this Ce-rich phase about 4x1mm scattered in and on matrix, from the type locality for the knopite variety first described in 1894. "Knopite" was later shown to be a perovskite-group phase rich in cerium, perhaps loparite-(Ce), but more extensive analytical work is needed to properly classify the mineral. Similar perovskite from Kola was sometimes found to actually be loparite and was later described as the new mineral    loparite-(Ce). An old specimen from the original locality for knopite, only one, matrix about 4cm across @ 60.00.

PLUMBOAGARDITE- Alforja Mine, Tarragona, Catalonia, Spain
This moderately rare mineral occurs here as tiny, pale green fibrous matted aggregates to micro needle-like hexagonal crystals elongated on [0001], typically associated with barite, quartz and possibly other phases. Strictly micro material, accompanied by a representative SEM image and EDS spectra with weight percents rom a Russian scientist, some showing modest praseodymium and other REEs as well. A new mineral for the locality and the first    occurrence of the species in Spain! Specimens range from about 1.5cm to 4cm across, priced according to quality @ 20.00, 30.00. 45.00 and 65.00 each.

QUARTZ-CHALCEDONY over CALCITE- Dyer Quarry, Gickerville, Berks Co., Pennsylvania
An uncommon specimen showing pale, greyish blue, botryoidal chalcedony richly covering one entire surface of tiny calcite that sit on a Jurassic diabase matrix. The piece was collected prior to 1974 (when acquired by us) and was recently uncover here from our old Tucson stock. Specimen measures a generous 12x9x3cm @ just 45.00.

RHODONITE in CALCITE/WILLEMITE- Sterling Mine, Ogdensburg, Sussex Co New Je
An old specimen, ex-Mike Bobinyak Collection, likely collected underground in the 1960s, as Mr. Bobinyak was a NJ State Mine Inspector at Sterling. The piece is comprised of granular white calcite (FL red SW) shot through with black franklinite grains as well as numerous small pods of willemite (FL green SW) as well. The rhodonite is lightly scattered about the piece in generally small pink masses, with a couple of small crystal faces (to nearly 1cm) evident on the top of the piece. A representative specimen from about 50 years ago, this heavy sample measures    about 15x8x5 cm @ just 55.00. List alternates!

RUTILE- Tokke, Telemark, Norway
Rather ugly stuff, acquired years ago from the late Claus Hedegaard, and represented here by crude, nearly black elongated aggregates to 1.2cm  of rutile scattered in pegmatitic matrix.These may be from the ilmenorutile occurrence at Spafjell, but the precise locality beyond Tokke is unknown. Specimens range from about 2cm to nearly 6cm across @ just 6.00, 15.00 and 25.00 each.

SILVER- Central City District, Gilpin Co., Colorado
From a small highgraded lot, we have a few well-formed dendritic native silver specimens, all showing bright, richly aggregated herringbone to wirey masses on minor matrix. Attractive thumbnail specimens from an excellent older locality, specimens from about 1.8cm to nearly 2.5cm @ only 20.00, 30.00 and 40.00 each. Neat!

STIBICONITE with STIBNITE- Santa Fe/Calvada Mine, Mineral Co., Nevada
Silvery-grey elongated aggregates of metallic stibnite lightly scattered in matrix, all with heavy overcoatings and replacement bodies of yellow to orange-yellow stibiconite richly covering these heavy specimens. The nature of stibiconite, while still IMA-approved, may someday be determined to consistently be a member of the roemite group, either one of several now known or another that could be a new mineral. For the moment, we are content to call these by their grandfathered name of stibiconite, pending analytical work beyond our lab's capability. Good    specimens from a seldom-seen locality, sizes from 3.5cm to nearly 9cm across @ just 10.00, 20.00 and 40.00 ea.

TAKANELITE- Marfa, Presidio Co., Texas
Minute, dull greyish submetallic masses sparsely scattered in light colored matrix fragments in a capsule. Rarely offered material, ex-Cureton stock,these from an interesting locality @ 25.00 per capsule.

TANTALITE-(Mg)- Lipovka Pegmatite, Rezh Area, Ural, Russia
This rare species, originally named "magnesiotantalite", occurs as thin rims intergrown with yellowish microlite surrounding dark red-brown manganotantalite in calcite/palgioclase matrix, occasionally with greenish yellow chrysoberyl. This Mg-end memeber (IMA # 2002-018) is rare and not visually distinguishable from the Fe-members of the series, and these samples have been individually checked to confirm the Mg-dominance! Only a few specimens available, type locality and author's material, sizes from 2.5cm to 6cm @ 175.00, 225.00 and 275.00 ea.



THALENITE-(Y)- Guy Hazen Prospect, nr. Kingman, Arizona
Old material collected in the 1960's, thalenite-(Y) occurs here as greyish to pale tan masses richly scattered in and comprising matrix. XRD  confirmed, only a few specimens from 1cm to nearly 2.5cm @ 20.00, 35.00 and 55.00 each. A rarity for Arizona!

VOLBORTHITE- Douglas Hill Mine, Artesia Lake, Nevada
Bright yellowish green flattened radiating platy aggregates of volborthite to 1mm sparely scattered on rock matrix, these often with pale green, fibrous malacite and occasionally brochantite or other species. From an old stock of this uncommon copper-vanadium species from Lyon County with moderate coverage and some decent micro potential as well, SEM-verified, matrix sizes from small TNs to nearly 10cm across @ only 10.00, 20.00, 35.00 and 55.00 each. Nice under the scope!

WODGINITE- Qgnevka Deposit, Kalba Range, Kazakhstan
Rich, black splendant masses of submetallic wodginite largely comprising matrix, these obtained many years ago from a Russian Museum. Some specimens may show very small relict simpsonite or other phases, but these were offered to us as superb examples of wodginite before the locality subsequently became the type locality for lithiowodginite and lithiotantalite. Only two samples available, about 6cm across @ 200.00 each.

YOFORTIERITE w/ POLYLITHIONITE- Mont Saint Hilaire, Quebec, Canada
From the original 1960's find, yofortierite occurs as pinkish hair-like fibers intergrown with flaky polylithionite, with    smaller amounts of other minerals, but often with rather large, globular analcime crystals as well. Fairly rich, colorful and well mixed material from a classic locality, many with micro potential as well. Sizes from 1.5cm to nearly 6cm @ just 20.00, 35.00 and 60.00 each.

ZERAVSHANITE- Dara-I-Pioz, Alaiskii Range, Tadjikistan
Another rare species from this prolific area, here as minute grains mounted in a 2cm probe mount, accompanied by an SEM backscatter image and X-ray spectra. IMA #2003-034, a new Cs-Zr silicate and a new structural type! Formula: Cs4Na2Zr3Si18O45*2H2O; author's material from the type locality, a few available @ 145.00 each.

ZEUNERITE-METAZEUNERITE- Majuba Hill, Pershing Co., Nevada
From an old hoard, fairly good specimens of small, flattened radiating plates of medium green zeunerite/metazeunerite sparsely scattered in exposed seams on matrix. The sprays extend to 6mm across, and they are highly lustrous against the dull, grayish rock matrix, these likely collected many years ago from the base    of the Copper Stope where the mineral was once found. Only a few specimens on hand, sizes ranging from about 2cm to 6cm, priced according to quality @ 15.00, 30.00 and 45.00 each, some with good micro potential as well!

Originally labelled in an old collection as "danaite", a cobalt-rich variety of arsenopyrite, we analyzed the piece and found no significant cobalt present. From an obscure and unrecorded locality, complete with our original chemical analysis, specimen size about 7x5cm @ just 50.00 (the cost of our analytical work!) with a former collection label of unknown origin. One only!

AUGELITE- Machacamarca Mine, Potosi, Bolivia
Excellent colorless, tarnsparent to translucent crystals of augelite to 5mm well scattered on rock matrix, occasionally with minor pyrite, barite or other species. The locality was the first to produce crystallized augelite in the world, later surpassed by Yukon material for "best in the world". We have a few old matrix specimens that average about 9x5cm with multiple crystals scattered about at just 85.00 each. List alternates!

AZURITE in GRANITE- Mount Godwin-Austen (K2), Baltistan, Pakistan
An unusual geological occurrence of flattened, circular azurite masses in pale grey granite, collected from a small area on K2, the second highest mountain in the world! Known as the "Savage Mountain" due to the difficulty and high death rate among climbing attempts, here is one locality few of us will ever visit in the Northern Areas of Pakistan. Some of this material has shown up in the past as crudely polished pieces, this is the first uncut specimen material we have been able to secure. Only a few samples available, sizes average 5 to 6cm across at just 25.00 each. Great locality material!

BISMOCLITE- Falcacci Stope, Rio Marina, Elba, Italy
This uncommon bismuth oxy-chloride occurs in these specimens as white, pearly to greasy micro platelets richly scattered on matrix, often associated with minute magnetite and/or relict pyrite. From the type locality for riomarinaite, we acquired these samples more than 30 years ago and have just recently rediscovered them in an old Dover, NJ crate. Small fragments in a capsule @ 15.00, matrix specimens from 1cm to 2cm across @ 25.00 and 40.00 each, one 4.5cm sample @ 125.00. List alternates!

CHRISTOFSCHAFERITE-(Ce)- Wingertsberg, nr. Mendig, Eifel, Germany
The rare mineral was IMA-approved (2011-107) several years ago, but little has found its way into collector hands. We recently obtained from one of the authors a few tiny crystals from the holotype material, each offered here as a black single micro aggregate in a 2cm vial! A rare mineral, the Mn2+ dominant member of the chevkinite group. Only a few available @ 110.00 each.

CORUNDUM variety RUBY- Kidal Region, Mali
Crude hexagonal crystals of opaque, pinkish corundum without matrix, these appearing slightly rounded and surface abraded. This is apparently a new find, and the locality remains somewhat of a mystery although nepheline syenites and related minerals are known from this obscure region. We have a small lot of single crystals ranging in size from about 2cm to 3cm tall, most with obvious prism faces and pinacoid terminations @ just 10.00, 15.00 and 20.00 each, depending on quality.

DIAMOND- Tshikapa, Kasai Province, Dem Rep Congo
From a old hoard of interesting diamond rough when DRC was still Zaire, we offer a small lot of seven (7) different diamond crystals packaged in a 2cm screw-top vial. Each lot will contain a range of hues, typically white to greenish, the vast majority showing usual cube habits. Crystals will range from about 1.5mm to 2mm across, total lot weight usually under 0.5 carats at just 30.00 per lot! Neat samples for micromounting or jewelry work, limit 3 lots per order, please! Domestic shipments only.

FERROSTRUNZITE- Marlton, Burlington Co., New Jersey
This largely undocumented (thus far) locality apparently produced a number of interesting phosphates, with the ferrostrunzite forming excellent radiating micro crystals and sprays tucked in exposed seams and vugs in brown, hardened mud-like matrix. Soon to be featured in a Mineral News article (currently being written by yours truly), these will make superb micros! Ex-Julius Weber material (and likely collected by the late Frank Leans over 35 years ago), specimens from about 2cm to nearly 5cm across @ just 7.50, 15.00 and 30.00 each. Excellent stuff!

FLUORAPOPHYLLITE over KINOITE- Christmas Mine, nr Hayden, Gila Co. Arizona
Unusually coarse crystals for the locality, hand culled from a large lot, these are sharp colorless crystals to several mm's, almost cubic in habit, covering deep blue kinoite and richly coating these matrix specimens. All will make excellent and colorful micromounts, from 2cm to nearly 5cm @ only 10.00, 20.00 and 35.00 each. Neat!

GOWERITE- nr Ryan, Furnace Creek, Death Valley, California
Rich coverage of this borate mineral on matrix! Gowerite is found as radiating tufts, to 0.5cm, of translucent microcrystals with moderate to thick coverage on at least one side of the matrix. Micro potential on this material, likely from the Corkscrew Canyon Mine, now impossible to obtain from this locality since its elevation to National Park status. Sizes from 3cm to 6cm @ 20.00, 40.00, 60.00, and 80.00 each.

HYDROZINCITE- Ojuela Mine, Mapimi, Durango, Mexico
Delicate, minute white sprays of micro crystals of hydrozincite richly scattered on gossan matrix. Old material from the late 1970's with good micro potential and brillaint, blue-white fluorescence as well, occasionally with hemimorphite or other phases! Matrix sizes from 1.5cm to 5cm @ 5.00, 10.00, 20.00 and 35.00 each, a few to 8x5cm @ 55.00 each.

IDAITE- Gruvberget, Kiruna Region, Lappland, Sweden
Rich metallic masses of idaite nicely scattered in rock matrix, most intergrown with other sulfides and with secondary copper minerals. Old material obtained from Hans Wilke many years ago, and mentioned in his book of Swedish mineralogy. Interesting locality material, sizes from 1.5cm to 4cm @ 25.00, 40.00 and 65.00 each.

ISOFERROPLATINUM (crystal!)- Konder, Ayan Maya, Far Eastern Reg., Russia
From a more recent find of CRYSTALS offered as native platinum, we have a nice selection of specimens averaging 3m to 5mm across, each showing slightly water-worn cubic faces. Each sample is accompanied by a copy of our chemical analysis, all showing these are actually isoferroplatinum. Others are charging up to $900 per gram(!!) for crystallized samples, we offer ANALYZED specimens at about half that price, at only 95.00, 125.00 and 150.00 each, all with documentation!

LAHNSTEINITE (IMA 2012-002)- Dornberg Mine, Ramsbeck, Germany
This relatively NEW SPECIES occurs as colorless to cloudy white triclinic crystals scattered on the surface of sphalerite-rich, Pb-Sb-S ore matrix. Formula: Zn4(SO4)(OH)6*3H2O - triclinic – IMA #2012-002. This is the second German locality for the species, provided by one of the authors. only a few small (1cm)
specimens with rich micro potential @ 185.00 each.

LITHIOPHORITE- Queen City Mn Mine, Nye Co., Nevada
Non-descript but exceptionally rich black masses of ugly lithiophorite comprising matrix, here with small amounts of fluorescent gibbsite as well. Recently featured in Mineral News, Vol. 33 (2017) No. 2 issue, andfrom one of only a few localities for the species in Nevada. Specimens range in size from about 3cm to 8cm across @ 7.50, 15.00 and 25.00 each. One 13cm specimen @ 55.00. List alternates!

MAGNETITE- nr. Bangassou, Mbomou Prefecture, Cent Afr Republic
Sharp, single octahedrons of well-formed magnetite without matrix, these averaging about 2.5cm tall! As expected, they are magnetic and show only a light rusty patina over the crystal faces. The original source for these excellent octahedral crystals has long been disputed, and a locality in Mindat refers to "Ilogo Prefecture", which does not exist in the Central African Republic! With only two small (and now defunct) known iron mining areas in the country, the locality is likely here in this SE area of the country, bordering on the Mbomou River and the Democratic Republic of the Congo. Well formed crystals, matrix-free, at just 15.00 each.

MALACHITE- Kolwezi, Katanga Copper Crescent, Dem Rep Congo
We have gathered a large selection of our better malachite specimens obtained over the years from this prolific district, here as both acicular, somewhat fibrous malachite, as well as rich botryoidal malachite, both habits that are appealing, sit well, and are excellent display specimens. These are MINERAL specimens, not polished pieces, and a wealth of sizes and habits are on hand from 5cm up to 12cm across, priced competitively at just 15.00, 30.00, 45.00, 75.00, 100.00 and 125.00 each. All are attractive, and a few higher are available, inquire!

MARGAROSANITE, CALCITE etc.- Jacobsberg, Nordmark Dist., Varmland, Sweden
A rather ugly rock comprised of densely packed biotitic mica and other phases, showing a non-descript patch of nicely fluorescent (SW blue-white) margarosanite plume about 3x2cm, with a similarly sized calcite (SW red-orange) mass perched at the opposite end of the piece. There are other crusty white phases on the same surface as well, but none are fluorescent. One specimen only, size about 6x6cm @ 125.00.

METAVARISCITE w/ VARISCITE- Lucin Hill, Box Elder Co., Utah
Excellent micro crystals of tabular to elongated transparent to pale green metavariscite crystals nicely scattered in seams with green variscite. Some crystals are nearly equant and show interesting twinning, and all have superb micro potential. Matrix sizes from 1.5cm to 4.5cm @ 7.50, 15.00, 25.00 and 45.00 each. Great stuff from an old locality, collected circa 1985!!

MUSCOVITE- Balch Farm, nr. Lyme, Grafton Co., New Hampshire
A rich and quite nice muscovite specimen comprised of thick, tabular muscovite plates to 3cm across forming a complex, intergrown group that shows only the divergent mica plates, but likely surrounding a hidden pegmatite core as evidenced by the surprisingly heavy weight of the specimen. With over 250 micabearing localities documented in Grafton County, this one is NOT among them, collected in September, 1945 by H.C. Moore and accompanied by his handwritten label. Overall specimen size is a hefty 8x5cm hand specimen @ 45.00. One only from this obscure, heretofore unknown locality of some 70+ years ago!

NONTRONITE with HEDENBERGITE- North Wilson Pit, Union Carbide Mine, Arkansas
This normally unappealing clay mineral occurs here at this Garland County property as rich, pistachio-green to yellowish crusts nicely covering a calcite-bearing carbonatite rock matrix that is rich in tiny, brownish black hedenbergite pyroxene crystals and masses. Old material recently uncovered here, specimens with good coverage for a normally ugly mineral, sizes from about 3.5cm to 8cm across at just 10.00, 20.00, 30.00 and 45.00 each.

NORDSTRANDITE- Poudrette Quarry, Mont St. Hilaire, Canada
The mineral occurs here as extremely small colorless to greyish-white radiating crystalline aggregates in tiny balls very sparsely scattered on feldspar matrix. We located a few older specimens in the Sole Collection, most in the 2cm-3cm size range at just 25.00 and 35.00 each.

NORRISHITE- Hoskins Mine, Grenfell, N.S.W., Australia
Black micaceous masses of this relatively new species scattered in/on matrix. A rare Mn-end member micagroup mineral obtained more than fifteen years ago from the type locality, sizes from 1cm to 4cm @ 20.00, 35.00, 50.00 and 65.00 each, depending on overall size and coverage.

OLIVENITE- Centennial Eureka Mine, Juab Co., Utah
Dark green, brilliant glassy olivenite micro crystals perched in vugs and on matrix, occasionally with malachite, chenevixite and possibly other species. There are two distinct habits, one long and slender, generally with pale green color (excellent micros!), and stouter, much darker green crystals. Good micro potential on these neat specimens, sizes from 1.5cm to 3cm @ only 5.00, 7.50 and 10.00 each.PYROXMANGITE- Conselheiro Lafaiete, Minas Gerais, Brazil
Rich, deeply hued, opaque pink-red masses and cleavages comprising matrix. Attractive, colorful material, originally identified as rhodonite but subsequently X-rayed and confirmed as the more uncommon species pyroxmangite! First obtained in 1995, we recently uncovered a small lot of this material, likely from the Morro da Mina property but not the gemmy, transparent rhodonite also found here. Matrix sizes from 2.5cm to 5.5cm @ just 15.00, 30.00 and 45.00 each.

QUARTZ variety CHALCEDONY- Unspecified Locality in Madagascar
Weird, globular to mammillary botryoids of translucent white chalcedony forming oddly-shaped clusters and "ear like" specimens, typically with little or no associated matrix. A mineralogical curiosity, specimens averaging 4cm to 5cm across at just 15.00 each. Strange!

SANTACLARAITE- Pennsylvania Mine, Santa Clara Co., California
Pink to tan masses of santaclaraite richly scattered in/on rock matrix. From the type locality Pennsylvania Mine that lies just east of Mt. Hamilton. Originally from very old Cureton stock supplied by Richrd Erd, the USGS mineralogist who described the mineral. Specimens range from 2.5cm to 6cm @ 15.00, 30.00, and 45.00 each; a fine and rich 8cm specimen @ 75.00.

SIBIRSKITE in PROBERTITE- Anatolia, Turkey
A single specimen of this rare species, here as intimately associated with crystalline probertite forming a 1cm TN. Likely from the Sankaya Boron Deposit near Kirka, the sample is ex-Br. Juan Salvador Collection, only only, @ 160.00.

SOBOLEVSKITE- Oktjabrskij, Talnach, Noril'sk, Russia
A 2.5cm probe mount containing a well documented ore sample from this prolific PGM locality. The specimen consists of minutely scattered sobolveskite in galena, accompanied by six (6) photomicrographs of X-ray maps pinpointing the element coverage throughout the sample. Specimen is about 1.2cm across in a 2.5cm probe mount @ 175.00. One only!

SPADAITE- Palos Verdes Hills, Los Angeles Co, California
An hydrous magnesium silicate mineral, spadaite occurs as light brown fibrous masses on matrix. Resembling a pale chocolate colored asbestos, the enigmatic and still questionable spadaite species apparently formed as a secondary mineral, developing substantial masses on one side of the Miocene sediment matrix. Likely from the Livingston Quarry at this locality and collected many years ago, sizes from 3cm to 6cm @ 35.00, 50.00, and 75.00 each, or smaller peices in a capsule @ 15.00. One huge 11cm specimen @ 175.00.

SPODUMENE variety KUNZITE- Gilgit-Baltistan, Pakistan
Before you get excited, these are NOT the gem kunzites from the region (we have those, too) but rather hefty, opaque spodumenes with a pronounced pinkish hue that show excellent fluorescence under both LW and SW UV, with the LW response (pinkish-orange) the better of the two! The specimens all show crude
crystal faces as well, but we were only able to secure of few of these fluorescent oddities, averaging about 5.5cm tall and up to 4cm wide at just 25.00 each. Limit one per order, please!

STILLWELLITE-(Ce)- Castellaccio di Petrignano, Latium, Italy
Very tiny, pale pink transparent crystals of stillwellite-(Ce) very sparsely scattered and perched in vugs among crystalline sanidine matrix. Typical associations include magnetite and occasionally other species, these from the 1977 discovery at this Vetralla locality. Specimens average 2.5-3cm @ 40.00 each, all with a pinpointing arrow.

THOREAULITE- Bakeanoe Ta-Deposit, E. Kalba Range Kazakhstan
This moderately rare tin mineral occurs here as thin, somewhat tabular yellow-brown platelets without matrix. A single plate just under 1mm across, most with some micro potential, packaged in a capsule @ only 35.00 each.

TINZENITE- Falotta, nr. Tinzen, Grisons, Switzerland
Dark, nearly black braunite and white barite comprise the matrix of these rather lean samples, here showing pinkish orange tinzenite lightly scattered in isolated areas of the specimens. One of several known localities in the Albula Valley near the type locality, specimens range from 2.5cm to nearly 4cm @ 35.00 and 50.00 each. Only a few on hand!

TYROLITE- Gold Chain Mine, Mammoth, Juab Co., Utah
Fine radiating micro aggregates and flattened crystal sprays of rich, greenish blue tyrolite nicely scattered in vugs and exposed seams on quartz-rich matrix. Some of the finest we've seen from the locality, these are 2cm to 4cm specimens, very reasonably priced @ just 10.00, 20.00 and 30.00 each, depending on quality and overall size/coverage. Good micro potential on better pieces!

WOLLASTONITE- Estrella Mts., Maricopa Co., Arizona
Radial aggregates of shimmering white wollastonite crystals are abundantly present throughout a greywhite, metamorphosed limestone matrix. Fluorescent bluish white in dull red matrix under SW UV. Reasonably attractive, sizes are from 2.5cm to 5cm @ 5.00, 10.00 and 15.00 each. Old material!

COLLECTION
PALERMO THUMBNAILS - Palermo Mines, Grafton Co., New Hampshire
Specimens from the collections of Dr. Michael Swanson, these are twenty (20) mounted specimens from
various Palermo collecting trips, some dating back to as early as 1960 and as late as the early 1980s. A
marvelous snapshot of the prolific phosphate discoveries of the time, there is modest duplication but a
wealth of classic Palermo species in the lot. Collection of 20 specimens mounted in labeled thumbnail sized
boxes at 175.00 per lot of twenty specimens.
EQUIPMENT
DIGITAL SCALE: 500g Capacity
We acquired a small lot of digital scales recently, testing them against our fairly expensive lab scales with
great success! These measure in grams(g), ounces(oz), troy ounces(ozt), hundred weight(dwt) and carats
(ct), with a 500 g capacity (or equivalent), accurate to 0.1g. The units run on 2 AAA batteries (supplied) and
are compact (10x6.5cm) devices you may find useful for weighing small specimens, cabochons, cut stones

CATALOG 21702 – Volume XLIV, No.2

AKERMANITE- Oka, Quebec, Canada
This uncommon Ca-rich Mg-silicate occurs widely in small amounts, here as greyish white to slightly yellowish aggregates lightly scattered in intruded alkaline rock matrix. Not much to look at, but older material ex-Canadian Geological Survey, a few samples from about 2.5cm to 5cm across @ 20.00 and 45.00 each; one extraordinarily large specimen sporting two drill holes from an old exploratory mining venture, about 12x10cm @ 150.00. List alternates!

AZURITE- Bisbee, Cochise Co., Arizona
Selected from numerous collections in our warehouse, we offer a modest range of classic Bisbee azurites obtained over the years, many pre-1950, some from museums, dealers and private collections. Typically small, dark blue druses, crystals and botryoidal crystalline knobs of azurite richly scattered on matrix, some with minor green malachite, all with micro potential and all with rich coverage. Specimens priced according to quality, sizes 2.5cm to 4cm @ just 20.00, 30.00, 50.00, 75.00 and 100.00 each. Old, classic material!

BARITE with PYRITE- Rosiclaire, Hardin Co., Illinois
An unusual combination of white to transparent platy barite crystals to 5mm well-scattered on greyish micro dolomites, also showing very rare (for the district) micro pyrite druses richly spread over the samples. Excellent TN-sized samples with good micro potential as well, the pyrite so rare from the Rosiclare district that images on Mindat are sorely lacking! Speicmens from about 2cm to 2.5cm @ 10.00 and 15.00 each.

BERYL variety EMERALD- Itabira, Minas Gerais, Brazil
Yes, emeralds can be ugly, and these are the ones! Dull green masses of poorly crystallized emerald generously fill these nondescript specimens, largely comprised of the green to greyish-green beryl and a dark mica (phlogopite?). While the color is distinctive, these are rather opaque and offer no serious gem potential nor sharp crystal faces. From the Iron Quadrangle, specimens average 4cm to 5cm long @ just 10.00 each!

CALCIOMURMANITE (IMA 2014-103)- Mt. Pyalkimpor, Lovozero, Kola, Russia
This NEW SPECIES occurs as pale pinkish tan micaceous plates to several millimeters wide, scattered in nepheline-rich lujavrite rock matrix, typically with fine-grained potassic feldspar, aegirine etc. Formula: (Na,[])2Ca(Ti,Mg,Nb)4[Si2O7]2O2()H,O)2(H2O4) - triclinic, IMA #2014-103. This locality is approximately 1km from the type where the species was found on an old museum sample. Fairly rich specimens, sizes from 2cm to 3cm across and priced according to size and coverage @ 150.00 and 195.00 each.

CALCITE pseudo @ FOSSIL CLAM- Azanarusawa, Chiba Pref., Honshu, Japan
Weirdly fluorescent (SW and LW bluish white) and briefly phosphorescent (pale green) translucent to white calcite has completely replaced the upper surface of a fossil clam shell. The underside of the shell is a mix of caliche-like shell fragments mixed with granular aggregates of numerous unidentifed mineral grains. A unique occurrence, with Japanese label, size about 5cm across @ 55.00. List alternates!

CLINOCHLORE var: KAMMERERITE- Kop Daglari, Erzurum, E. Anatolia, Turkey
One of the more handsome examples of this chromian clinochlore that we've had, these samples show numerous, deep magenta colored crystals to 5mm on the better samples nicely scattered over one surface of rock matrix, most showing a good triangular outline and raised slightly from matrix. Old and very colorful material from the 1970's, specimens from 3cm to nearly 6cm @ 50.00, 75.00, 100.00, 125.00 and 150.00 ea

COVELLITE- Lily Mine, Pisco Prov., Ica Dept., Peru
From the locality better known for its "Andean Opal", we have a small lot of rather rich, dense, massive blueblack metallic covellite, intergrown with minor pyrite, quartz and possibly other phases. The material is quiteheavy and takes an excellent polish, sold for lapiday use starting at $100 a pound! Our samples are rough chunks from 4cm to 11cm across, certain to turns your hands black when handling, offered at just 20.00, 35.00, 50.00 and 75.00 each. A few specimens with one cut face and lightly buff polished, 5cm to 9cm across the face @ 30.00, 55.00 and 80.00 each

DESCLOIZITE- Overland Mine, White Pine Co., Nevada
From a uncommon locality in Nevada, we have an interesting lot of attractive, red to orange-red descloizite, here as thin crusts of minute botryoidal knobs richly scattered on matrix, some with a paler yellow-orange color but still analytically confirmed as descloizite. Attractive specimens under the scope as well, the locality is one of many old and obscure mining prospects listed in the County Recorder's records, but not mentioned in any mineralogical or geological reference we can find! Heyite has been reported in the area as pseudomorphs after descloizite, but we found little or no iron in any of our analyses. Colorful specimens, very reasonably priced and featured in Mineral News (September, 2012), sizes from about 3cm to 7cm @ 7.50, 10.00, 20.00 and 30.00; a few larger, 10cm to 15cm long @ 50.00, 65.00 and 80.00 each, all with a copy of an analysis!

DIAMOND- Zimi Region, Western Area, Sierra Leone
Best known for its brilliant yellow diamonds, the Zimi region was once rich in excellent, highly productive diamond deposits, but production has largely moved to eastern parts of the country. We recently uncovered some old (ex-David New) crystals in the inventory, offered here as pale amber-brown, highly striated cubic crystals without matrix. Under the scope, these show remarkably complex morphology. Sizes include: 4x4x3mm (0.62 cts) @ 90.00; 5x4x3mm (0.80 cts) @ 120.00. List alternates!

DIOPTASE on MALACHITE etc.- Tsumeb, Namibia
An old specimen comprised of a half dozen small (2mm) deep green dioptase crystals perched on one edge of large, cauliflower-like, velverty botryoidal malachite specimen, also with a few small greysih whilte dolomites and a partial 1.5 cm fragment of a wulfenite crystal sitting in the middle of the specimen. Ignoring the dioptase and wulfenite, this is an otherwise excellent Tsumeb malachite brought out circa 1980, the associations making it especially desirable, overall measuring a hefty 8.5cm across @ just 200.00. Nice!

FERRI-FLUORO-LEAKEITE- Flora Mt., Lovozero, Kola Peninsula, Russia
A new locality for this complex amphibole species, here as short prismatic black crystals to a few millimeters long, lightly scattered in fenite matrix, largely comprised of quartz and alkali feldspar, occasionally with trace beige colored narsarsukite as well.

FRAIPONTITE- Silver Bill Mine, Cochise Co., Arizona
This uncommon mineral occurs here as pale blue masses and streamers running through matrix, most associated with micro hemimorphite, calcite and occasionally altered galena as well. Moderately colorful material collected over 25 years ago, ex-Cureton specimens from 2.5cm to nearly 9cm across @ 10.00,
20.00, 35.00 and 55.00 each.

GIBBSITE with LITHIOPHORITE- Queen City Mn Prospect, Nye Co., Nevada
Opaque, off-white cherty masses of gibbsite are the primary matrix mineral in these decidedly ugly specimens, with black lithiophorite appearing as spots and small masses scattered about the gibbsite. Recently described in Mineral News (2017, Vol. 33, #2), the material is weakly fluorescent (SW - green),
perhaps it's only redeeming characteristic other than it represents one of the few reported occurrence of lithiophorite in the state, and the only Nye County occurrence of gibbsite! Likely one of the ugliest (but still interesting) mineral combinations of all time, offered here in sizes from 3cm to 7cm @ just 7.50, 15.00 and 25.00 each.

GOSLARITE- Grube Rammelsberg, Goslar, Harz, Germany
Goslarite from this excellent old type locality occurs as nearly pure friable, tan opaque and somewhat powdery masses comprising matrix. Offered as a generously filled capsule @ 12.50, or as solid masses from 1cm to 3cm @ 25.00, 40.00, and 55.00 each.

GOUDEYITE- Majuba Hill, Pershing County, Nevada
Bright to pale green coatings and micro-botryoidal crusts of this rare aluminum copper arsenate, found in the 'Copper Stope' of this prolific Nevada locality. Collected by Forrest Cureton many years ago, most have good micro potential and are associated with other arsenates. Priced according to size and quality, from 2cm to 5cm @ 15.00, 25.00, 40.00, and 65.00 each.

GRAFTONITE etc.- Rice Quarry, Groton, Grafton Co., New HampshireRed-brown crystalline masses of graftonite are embedded and intimately associated with altered triphylite and occasionally bluish vivianite, richly comprising matrix in this old and rich phosphate assemblage. Collected over 40 years ago, excellent locality specimens, sizes from about 2.5cm to 4cm @ 15.00, 20.00 and 30.00 each.

GROSSULAR variety HESSONITE- Jeffrey Mine, Asbestos, Quebec, Canada
Recently uncovered in the warehouse: an old lot of transparent, pale orange to cinnamon colored grossular garnets (variety "hessonite")scattered on matrix, collected in 1972 by the late Russell Buckingham! Still wrapped in local newspapers, these are small (largest xl to 1cm), complex and generally flattened and somewhat crude dodecahedral and trapezeohedral crystalline aggregates on rock matrix, occasionally with minor diopside or other species. Specimens range in size from about 3cm to 12cm across, with coverage light to fair on larger matrix samples. While not the killers this mine once produced, they are representative of the variety and typical of field collected specimens of the time. Priced according to quality/size @ 10.00, 20.00, 30.00, 40.00 and 55.00 each.

HEMIMORPHITE- Sterling Hill, Ogdensburg, Sussex Co New Jersey
An interesting miniature comprised of white, botryoidal hemimorphite completely covering thin rock matrix, with evidence of concentric banding seen from the side of the specimen. The underside shows many micro crystals that are considerably more transparent than the opaque surface botryoidal mass, and the surface is mildly fluorescent under both SW and LW. Size about 5.5x3cm @ 45.00. One only.

HYDROCERUSSITE- Mendip Hills, Somerset, England
Off-white crystalline masses of hydrocerussite are richly scattered with white calcite (easily distinguished by FL-red SW UV) and blackish brown manganese minerals composed primarily of crednerite in these rich specimens from the classic Higher Pitts location. Old material, ex-Cureton, sizes from 2cm to 6cm @ 15.00, 25.00, 40.00 and 55.00 each.

JARLITE- Ivigtut, Arsuk Fjord, Greenland
Jarlite is one of several strontium bearing fluoride minerals first noted from this unusual and prolific pegmatite. Jarlite occurs here at the type locality as greysih crystalline to vuggy masses, associated with fluorite, and possibly containing areas of drusy jarlite as well. Old material, sizes from 3cm to nearly 6cm @ 30.00, 45.00, and 65.00.

LAURELITE- Grand Reef Mine, Laurel Canyon, Arizona
Minute, elongated clear rod-like crystals of this rare species packaged in a gelatin capsule with associated galena, anglesite etc. Lustrous micro crystals and aggregates to a couple of millimeters long, and missing from many reference collections!. Type locality material collected about 25 years ago; good micro potential, @ only 35.00 per capsule of material.

LIMONITE pseudo @ PYRITE- Marion Co., Kentucky
From a small box of old Ward's material, these are typical limonitic pseudos after pyrite, all matrix-free and crystal forms ranging from pyritohedrons and cubes to weirdly elongated rectangular crystals.

LITHIOTANTITE w/ THOREAULITE- Ognevka Deposit, Kalba Range, Kazakhstan
A surprising find from the type locality for the species, here as unusually large (to 1mm) colorless and highly lustrous grains intimately associated with bright yellow, glassy thoreaulite and occasionally with dark brownish cassiterite as well. Small samples to a several millimeters across but excellent for type locality specimens, only a few on hand @ 125.00 each.

LIZARDITE pseudo @ ENSTATITE- Kennack, Lizard, Cornwall, England
Small platy aggregates of "bastite" to a few millimeters across, richly scattered in dark martrix. These are lizardite pseudomorphs after enstatite, and many older labels simply called them "bastite" or "enstatite" or even "bronzite". From the TYPE LOCALITY for lizardite, classic stuff obtained many years ago, only a few specimens on hand, sizes ranging from about 2cm to 4.5cm @ 15.00, 25.00 and 40.00 each.

MAGADIITE w/ SILHYDRITE etc.- Trinite Mine, Trinity Co., California

This is type locality material for silhydrite, sometimes designated as near Watson Creek, specimen sizes from 1.5cm to 5cm @ 20.00, 35.00, 50.00 and 65.00 each. A rare assemblage!

MAGNESIOHATERTITE (IMA 2016-078- Arsenatnaya Fumerole, Tolbachik, Russia Another NEW SPECIES from this Kamchatka volcano, here as minute, dark blue-grey crystals intergrown into tiny aggregates and groups without matrix. Formula: (Na,Ca)2Ca(Mg,Fe3+)2(AsO4)3 - monoclinic, IMA approved #2016-078, the Mg>Fe analog of hatertite. A skilled photomicrographer would likely get an excellent image of these tiny crystal groups, but barely 1mm across is beyond our limited photo capability! Tiny samples, mounted on adhesive disks @ 175.00 each. List alternates!

NABALAMPROPHYLLITE- Kovdor Massif, Kola, Russia
Repeat of a sellout: this NEW SPECIES occurs as small, yellowish brown prismatic aggregates scattered in matrix, typically with minor feldspar, lorenzenite and possibly other phases.

Good examples of isolated cubes shot through ore-bearing rock, not especially attractive but inexpensively offered for specimens from 5cm to 10cm across @ only 10.00, 25.00 and 40.00 each. Heavy stuff and will likely require larger priority box postage.

QUARTZ with INCLUSIONS- Sichuan Province, PR China
A recently acquired small lot of well formed singly terminated, transparent quartz crystals, all showing inscrutable inclusions of an unknown black, somewhat wispy, material, some appearing rod-like when travelling along an internal fracture plane. We have seen similar material from both Leshan and Liangshan Prefectures in Sichuan, variously labelled as bitumen, hematite or graphite, with a hydrocarbon being the most likely candidate for the inclusion ID. Interesting crystals, averaging 6cm-7cm tall at just 20.00 each.

QUARTZ-AMETHYST "Grape Agate"- Mamuju, Sulawesi Barat Province, Indonesia
We have been able to secure a few more of these fascinating specimens from last year's discovery of these extraordinarily attractive specimens that have been called chalcedony as well as "grape agate". These are actually tiny radiating amethyst crystals forming wonderful balls and botryoids of pale purple color completely scattered on and about the samples, looking much like small bunches of miniature grapes (and hence, the name)! Quite attractive and a unique habit from an obscure locality, specimens range from about 6cm to 9cm across with varying heights and depths, priced very reasonably at just 35.00, 50.00, 65.00 and 85.00 each. Nice stuff!

SENEKEVICHITE- Dara-i-Pioz, Tien Shan Mtn., Tajikistan
This exceptionally rare species occurs as micro aggregates in fluorite/quartz matrix, some with minor neptunite, leucosphenite or possibly other phases. A relatively new cesium mineral, formula: CsKNaCa2TiO[Si7O18(OH)], IMA-approved over 10 years ago (2004-017) but rarely available since. The cesium analog of tinaksite, type locality material from the author, offered as small microprobed samples in a 1.8cm mount, accompanied by an SEM image and full quantitative chemical analysis @ 225.00. List alternates!

SPHALERITE var: SCHALENBLENDE- Pine Point, Northwest Territories, Canada

An out-of-the way locality just south of Great Slave Lake with many small prospect pits within its underlying Mississippi Valley-type lead-zinc deposit. Polished face size about 10x9 cm @ just 75.00. One only!

STRACZEKITE- Union Carbide Mine, Wilson Springs, Arkansas
Greenish-black micro crystals and platy aggregates of straczekite scattered on cherty matrix. An unusual species from this prolific locality, some associated with minor yellow metatyuyamunite. Type locality material from the North Wilson Pit, sizes from 1.5cm to 5cm @ 15.00, 25.00, 35.00, 50.00 depending on size and coverage. Rarely seen on the market today!

TANEYAMALITE- Taneyama Mine, Toyo, Kumamoto Pref., Japan
Specimens from the type locality (!!) obtained over 30 years ago from a Japanese scientist, offered here as dark, greenish brown to nearly black somewhat wavy and vitreous fibrous aggregates sparsely scattered in seams in an iron-rich, metamorphosed chert matrix. The mineral is the Mn-analog of howieite, and legitimate specimens from the type locality are rarely available. Only a few specimens on hand, as small 2+cm TNs @ 35.00; or as considerably larger ore chunks to 6cm @ 125.00 each.

VICANITE -(Ce)- Vico Complex, Tre Croci, Vetralla, Italy
Minute euhedral yellowish-green crystals of this rare mineral sparsely scattered in vuggy sanidine matrix, occasionally covered by or with pale brown micaceous blades of tadzhikite-(Y) and possibly other rare species. A rarely offered Ca-Ce-Th arsenate, these with micro potential. Each specimen is arrowed, sizes from 2cm to nearly 4cm @ 35.00, 45.00 and 55.00 each, depending on quality.

Formula: Ba8(Ba3Li2[])Be24P24O96*32H2O, cubic, IMA # 2015-034. Named by the senior author for the late William and Anne Cook, avid systematic collectors and micromounters. The crystals are quite small (0.2mm) and will require at least 20x, but they are lustrous and well-formed micros! Small matrix samples to a few millimeters in a micro box, priced according to the number and/or quality of crystals, @ 60.00, 90.00 and 125.00 each.

SYNTHETIC "ORANGE SAPPHIRE"- Lab Grown Quartz from China
We recently acquired a fairly robust lot of wonderfully large, laser-cut faceted ovals, purported to be synthetic sapphire. A few quick tests suggests these are actually lab-grown quartz, admittedly of a fine, orange padparadscha color, but closely resembling fine citrine. While the real padparadscha sells for over $2000 a carat, we will blow these out at about 1.50 a carat, with nicely cut, perfectly clean faceted ovals ranging in size from about 18x13mm to monster 28x22mm (about 20 carats to nearly 40 carats) at 30.00, 45.00, 50.00 and 60.00 each. Impressive, but still synthetic! Order by price, please!

Originally ex-Kiril Spiroff (1901-1981, the mineral namee for spiroffite) and donated to the Michigan College of Mines where he became curator after Seaman's death in 1938. His early career was as a mining engineer in the West before returning to Michigan. The locality label, specifying "Hidden Treasure Gulch" is unrecorded in Mindat, and the Elliston area is covered with numerous claims and old mines (Big Dick, Golden Anchor, Evening Star etc.). A superficially ugly rock, overall size about 6x4cm @ 55.00. For the connoisseur of Montana locality minerals, the piece has some historic provenance as well!

TURQUOISE (Crystals!)- Bishop Mine, Lynch Station, Virginia
From the classic locality for crystallized turquoise, we have a small selection of excellent mounted specimens, all showing fine, blue, wedge-shaped micro crystals on quartz/schist matrix. The Bishop Mine was the first reported locality for crystals of turquoise, and this Campbell County site remains today as one of the finest occurrences of the mineral despite being worked out long ago. Specimens to 1.5cm in standard micro boxes, priced according to coverage and quality @ just 25.00. 35.00 and 45.00 each. The last of our stock with limited availability!

VESUVIANITE- nr. Blue Bird Mine, Mineral Co., Nevada
From a new find at an unnamed prospect near the Blue Bird Mine, we have a good selection of small, pistachio green vesuvianite crystals richly lining exposed seams and cavities, most carefully etched out of calcite and therefore showing good prism faces and terminations, most samples with full surface coverage as well.

BOOK
PORTFOLIOS of MINERAL- PHOTOGRAPHS - Parts 1 & 2
These two mineral portfolios were produced about 15 years ago by the same people who now publish the
fine, glossy Mineralogical Almanac magazine in Russia. Each portfolio contains 12 different color mineral
photographs (yes, actual glossy photographs!) as generously sized 15x15cm (about 6 inches by 6 inches)
images, carefully mounted on heavy, slate-grey stock and contained in a matching slate-grey folder. Each
mineral is identified on the back of the mounted image in both Russian and English. Set #1, "The Creative
Earth" has a dozen different aesthetic specimens on generally dark backrounds, while Set #2,"On Planet
Earth" offers a dozen attractive samples superimposed on natural backgrounds such as fields, lakes,
mountains etc., certainly more nature-oriented than the first set. We have very limited quantities of each set,
with #1 (minerals only) offered @ $35.00/portfolio, and #2 (minerals + nature) @ $25.00 per portfolio of 12
different; order early and get both for just $55.00. Real photographs suitable for framing!

An uncommon intrusive rock type, this carbonatite was collected by famous geologist/mineralogist E.W.
Heinrich and is accompanied by his label. Often containing minerals that are unusual in igneous rocks, the
specimen is a hefty 13x6 cm and shows odd, dull, brick-red sphalerite richly scattered in the carbonatite,
with a few small areas of fluorescent calcite evident as well under both LW and SW UV. Small dendrites of
unknown composition are also present, and this petrological curosity is just 55.00, with Heinrich's label.

Our latest list, the last for this year, has a number of new species, as well as our usual assortment of rarities, old classics and interesting locality pieces. Also, this list continues the unveiling of long-held petrology specimens from E.W. Heinrich and others, and for those of you interested in such samples, note that, like minerals, they are offered on a first-come, first-served basis, FOB our warehouse.

ANDALUSITE var: CHIASTOLITE- Sangping Mine, Xixia, Henan, PR China
These are sliced and polished (one face) cross sections of andalusite crystals (variety chiastolite) showing typical cross patterns due to carbon inclusions so well known in this variety. Only a few on hand, slices from about 2.5cm to 3.5cm across at just 15.00 and 20.00 each.

ARSENATROTITANITE (2016-015)- Arsenatnaya Fumerole, Tolbachik, Russia
Another NEW SPECIES from this famous Kmachatka volcano, these from the second scoria cone of the northern breakthrough fissure eruption. The mineral occurs as minute (<1mm) single red distorted crystals and clusters, each individually mounted on an adhesive pad. Formula: NaTi(AsO4)O, monclinic, IMA #2106-015. Type locality material, a new member of the tilasite-durangite group and isostructural with titanite, named for its composition. Very little material available @ 125.00 each. List alternates!

AZURITE - Gold Quarry Mine, Eureka Co., Nevada
Nice micro crystals and druses of azurite, from the same material often described as"the best known" from Nevada. These are sharp translucent deep blue to 1-2mm crystals, usually associated with malachite and occasionally other copper minerals, with over 110 different species recorded from this prolific mine! Good micro material as well, matrix sizes from 2cm to 5cm @ only 7.50, 12.50, 20.00 and 30.00 each, with midpriced TNs generally the best coverage.

BADALOVITE (2016-053)- Arsenatnaya Fumerole, Tolbachik, Russia

Formula: Na2Mg2Fe3+(AsO4)4, monoclini, IMA #2016-053, the first of several new members of the alluaudite group from this Kmachatka volcano. The mineral is named for Stepan Tigranovich Badalov (1919-2014), professor at the Abdullaev Institute of Geology & Geophysics in Tashkent at the UIzbekistan Academy of Sciences. Nice vuggy matrix specimens averaging 2.5cm @ 175.00 each, all with modest micro potential as well!

BARITE- Onderra Mine, Kaokoveld Plateau, Namibia
From the early find about ten years ago, these are small, transparent, yellowish, glassy barite crystals with little or no matrix, these averaging about 1 cm tall and supplied in clear micro boxes. Moderately attractive small TNs with good form and color for the princely sum of 7.50 each. Limit three per order, please.

BETEKHTINITE- Dzhezkazgan, Karagandy Province, Kazakhstan
A superb miniature of this rare Cu-Fe-Pb-sulfide, here as grayish black, elongated crystalline aggregates showing good separation and aesthetically presented in a complex group with little matrix. The piece is exUniversity of Arizona (#14182) and is accompanied by their black on transparent display label. Well formed, moderately attractive for a typically ugly mineral, a 4cm group @ 225.00. One only!

BURBANKITE with SODALITE etc.- Cerro Sapo, Cochabamba Dept., Bolivia
Small pinkish micro druses and crusts of burbankite lightly scattered on matrix, typically with pale blue masses of sodalite, pale green to grey ankerite and massive, sugary barite. From one of the very few alkaline provinces in the Andes, burbankite is one of the unusual minerals found among the 50+ species
known from the locality. Specimens range from about 3cm to 5cm at just 20.00, 35.00 and 50.00 each.

CALAMAITE (2016-036)- Alcaparrosa Mi, Calama, Antofagasta, Chile

Formula: Na2TiO(SO4)2*2H2O, orthorhombic, IMA #2016-036. The mineral is named for this, the type locality, Calama commune in which the mine is situated.
Only a few specimens on hand, averaing in the 2-2.5cm size range @ 195.00 each.

CLAUDETITE- Allchar, Roszdan, Macedonia
Minute, white micro elongated, crystalline aggregates of this uncommon mineral, lightly scattered on matrix and occasionally with minor realgar. The mineral, one of more than 50 known from this classic locality, is a dimorph of arsenolite and occurs in fewer than 20 countries worldwide. Modest micro potential and only a few available, sizes average about 3cm across @ 55.00. One superb and very rich specimen about 4x4cm @ 125.00. List alternates!

COPPER (w/ Drill Hole)- Keeweenaw Peninsula, Michigan
An unusual, sculpture-like display specimen from an undocumented locality in Michigan's Copper Country, ex-Buckingham Collection. The specimen has a dense rock base about 13x10 cm with a large native copper-impregnated rock mass about 10x10cm protruding and extending upward from the base. The copper shows one complete and one partial drill bit impression from a miner's 4cm diameter drill, the impression piercing directly into the copper and leaving a stepped rotary pattern and a small central nipple in the copper mass! A marvelous mining artifact specimen that has not be cleaned (which would likely improve appearance greatly!), weighing about 6 pounds and measuring about 14x13x13cm @ 275.00. One only!

DAVIDITE-(Y) in TITANITE- Quijotoa Mts, nr, Covered Wells, Arizona
An old batch of davidite-(Y) specimens, originally from famous mineralogist Richard Gaines (gainesite) and each sample accompanied by a copy of his label. The mineral occurs here as dark brown to nearly black masses and pods lightly scattered in massive titanite/rock matrix, subsequently identified in Cureton labels as originating from the Pandora Prospect which is by the Papago Indian Reservation in Pima County, close to the Linda Lee Claims. Only a few samples available, sizes from 1.5cm to 4.5cm @ 15.00, 30.00 and 55.00 each, with a large 7.5cm sample @ 95.00. List alternates!

FLUORITE- Cumberland, England
An exceptionally large (and old!) specimen, comprised of several, well formed, large cubic crystals to 8cm on edge (!!) densely intergrown over the entire sample and perched on a thin rock matrix. The specimen shows pale purple to clear areas under ordinary light, and extraordinary and brilliant blue-white fluorescence under both SW and LW UV, with the latter being very striking. Unlike many U.S. fluorites, UK specimens often show good transparency as this one does, and the piece is ex-A.E. Seaman Museum and E.W. Heinrich, famous geologist and one of the Museum's great benefactors. The piece shows many cleaved edges on the cube faces and a typical assortment of dings throughout, but that all disappears under the intended UV display specimen that it is. Overall museum-size sample about 23x16x13 cm, weighing nearly 15 pounds (!!) of solid, cubic fluorite, only one available @ 1500.00. Wow!

FLUORITE on BARITE- Danville, Boyle Co., Kentucky
Delicate, pale purple cubes to nearly 1cm are nicely scattered over numerous spikes of white, needle-like barite, perched on limestone matrix. A rather attractive specimen in which the fluorite shows interesting color-zoned edges on the cube faces. Likely from the Caldwell Quarry but not labeled as such, a neat specimen from this old Kentucky fluorspar district. A relatively flat specimen, overall size about 9x7cm @ 65.00. One only!

HEULANDITE-Ca with CELADONITE- Nasik, Maharashtra, India
A large specimen of GREEN heulandite, here as well formed crystals to 1.5cm richly scattered over the entire surface of the specimen, overlaying broadlaths of flattened stilbite sitting under a thin chalcedony layer. The murky green color of the unusual heulandite is caused by inclusions of celadonite, and it does not detract from the moderately vitreous luster of the heulandite. Hefty and quite attractive with an uncommon color, overall about 12x9cm @ just 65.00.

HUREAULITE in TAVORITE- Bull Moose Mine, Custer Co., South Dakota
Small pods of micro-crystalized hureaulite entrapped in dark green masses of tavorite matrix, occasionally with other phosphates and minor micro potential as well. The Bull Moose is a very well-known but surprisingly small deposit, consisting of workings about 25 x 10 feet in total. Only a few old specimens on hand, sizes from about 2.5cm to 5cm @ just 10.00, 20.00 and 35.00 each.

KINGSMOUNTITE (TL)- Foote Mine, Kings Mountain, North Carolina
This uncommon phosphate occurs here at the type locality as tiny, white radiaiting crystals lightly scattered on matrix, typically with nearly black birnessite and/or mitridatite. Kingsmountite is the ferroan analog of montgomeryite and was first foun din 1968 but not described until more than 10 years later. Modest micro potential, specimens from about 1.5cm to nearly 3cm @ 20.00 and 40.00 each.

KOROBITSYNITE (TL)- Umbozero Mine, Alluaiv, Lovozero, Russia
Small translucent greyish-white bladed crystals of this rare species scattered on matrix, some with epitaxial needles of nearly transparent elpidite crystals, aegirine and albite as well. Korobitsynite is the Ti-analog of nenadkeichite, and these are type locality specimens as well! Sizes from about 1.5cm to nearly 4cm @ 45.00, 75.00, 100.00 and 150.00 each for the best samples.

KOTOITE (TL)- Hol Kol Mine, Suan-gun, North Korea
Minute transparent to translucent aggregates of this rare borate sitting with small pods of white, somewhat fibrous szaibelyite sparsely scattered in dense, greyish dolomitic matrix. Type locality from a rarely offered locality, only a few small 1.5cm specimens available @ 75.00 each. List alternates!

LAVENITE- Laven Island, nr. Stokkoya, Norway
Small yellowish-brown grains of lavenite sparsely scattered in nepheline/barkevikite/aegirine matrix from this type locality. Not attractive but classic nonetheless. Sizes average 2cm to 5cm @ 10.00, 20.00 and 35.00 each. A few larger, ex-E.W. Heinrich, to 9cm @ 75.00 each.

LAZULITE in QUARTZITE- Graves Mt., Lincoln Co., Georgia
Classic locality material showing crude crystals of lazulite to 1cm on the better pieces lightly scattered in sandy, granular quartzite matrix. A fairly large selection available from this old locality, specimens not as pretty as they sound and priced according to size and quality from about 2cm to 7cm across @ just 10.00, 20.00, 35.00 and 55.00 each.

LIMONITE-MALACHITE STALACTITE- Dragon Mine, Tintic, Utah
An old and obscure specimen, ex-Michigan College of Mines, labelled simply as "Limonite - Dragon Mine, Tintic, Utah". The sample is actually a solid "finger" of warty limonite/goethite forming the outer surface of a stalactitic mass, the core comprised of excellent, needle-like fibers of malachite forming around the internal, hollow core of the stalactitic rod and radiating inward toward the remaining tubular void. It would appear that this was once a stactite/stalagmite, subsequently encrusted, then the core replaced and filled with later forming malachite. A unique specimen, malachite unreported from any of the four "Dragon Mine" localities in Utah, overall size about 6cm long and a tapered 1.5cm wide @ 75.00, with the malachite exposed at both ends. One only!

MICROCLINE- Morefield Mine, Amelia Co., Virginia
Dull beige massive microcline comprising matrix, occasionally with minor quartz or rarely with small black masses of unanalyzed columbite-tantalite phases. Not attractive but modest reference samples from this historic locality, specimens from about 2.5cm to 9cm across @ just 4.00, 7.50, 15.00 and 25.00 each.

MOSANDRITE- Laven Island, Langesundfjord, Norway
Several dark amber-brown, prismatic crystals of this rare-earth bearing silicate occur in a complex, coarsegrained nepheline syenite matrix. The crystals only occasionally show faces (prism) since they are exposed in cross section (both longitudinally, and as sharp, diamond-shaped sections normal to the c-axis) along the rock's fracture surfaces. Several other interesting, crystalline species occur in this material, including zircon and others. Specimens primarily ex-E.W. Heinrich, sizes range from about 2.5cm to 8cm across @ 20.00, 35.00, 55.00 and 70.00 each.

PARSETTENSITE- Foote Mine, Cleaveland Co., North Carolina
Old material collected many years ago and informally called “unknown #2”, consisting of richly scattered bronze-brown radiating spherules and frothy , platy aggregates of micro parsettensite well scattered in vugs on white albite matrix, the smaller samples sometimes underlying pink rhodochrosite. Attractive micro material from this prolific locality, with odd-ball associations possible with careful study. Matrix specimens from about 1.5cm to nearly 5cm @ 15.00, 30.00 and 50.00 each.

PHILIPSBURGITE (TL)- Black Pine Mine, nr. Philipsburg, Montana
Recently uncovered in our warehouse, a flat of excellent, emerald-green micro crystals of philipsburgite scattered over quartz matrix, typically showing finely bladed micro crystals and rosettes! The crystals are typically overgrown with minute quartz druses, making colorful, pale green vitreous balls, sometimes associated with pale green duftite, malachite etc. Matrix sizes from 2cm to 6cm @ 15.00, 25.00, 45.00, 65.00 and 100.00 each for the most aesthetic. Superb type-locality material, and all with micro potential, too.

PROBERTITE- Borax Open Pit, Boron, Kern Co., California
From the 1987 find from Extension 18, these are sharp, slender elongated probertite CRYSTALS and radiating, divergent aggregates comprising matrix. Most specimens show rounded, warty terminations and are from the finest US occurrence ever reported for the species. Many show dull yellowish orange FLresponse under SW UV. Specimen sizes from about 2.5cm up to 6cm specimens, priced at 10.00, 25.00, 45.00 and 60.00 each. Excellent with decent display potential as well!

QUARTZ var: POLYCHROME JASPER- Sofia Region, Mahajanga Province, Madagascar
Very attractive, polished end-cuts of this excellent, banded and colorful jasper, a cryptocrystalline variety of quartz. Predominant colors are typically gentle shades of rusty brown and tan, with occasional splashes of greys, greens etc. Expertly cut and polished faces average about 7x5cm on each specimen, only a few available at just 20.00 each.

QUARTZ-AMETHYST "Grape Agate"- Mamuju, Sulawesi Barat Province, Indonesia
From the recent find of these extraordinarily attractive specimens that have been called chalcedony as well as "grape agate", these are actually tiny radiating amethyst crystals forming wonderful balls and botryoids of pale purple color completely scattered on and about the samples, looking much like small bunches of miniature grapes (and hence, the name)! Quite attractive and a unique habit from an obscure locality, specimens range from about 6cm to 8cm across with varying heights and depths, priced very reasonably at just 35.00, 50.00 and 65.00 each. Nice stuff!

ROMANECHITE- Fourth Payday Mine, Sierra Co., New Mexico
A new locality for the species, located within the Burnt Cabin Flat area of the Taylor Peak quadrangle in Sierra County. The original find of the specimens was thought to be botryoidal cassiterite because of its very high density and rich luster, but XRD and EDS confirmed romanechite as the species, here as rich, black botryoids of nearly pure material. Moderately attractive for a black species, we have a modest selection of solid and very heavy botryoidal samples ranging from about 3cm to 8cm across at just 10.00, 20.00, 35.00 and 55.00 each. Neat!

SHIMAZAKIITE (IMA #2010-085a)- Fuka Mine, Bitchu-cho, Okayama Pref, Japan
This rare mineral occurs here at this prolific locality as nearly pure, greyish white masses comprising matrix, rarely associated with extremely small, pale violet henmilite or possibly other species scattered in matrix. A relatively new anhydrous calcium borate, IMA #2010-085, type locality, of course. Only a few small specimens on hand, averaging about 1cm across at just 45.00 each. Rich!

TOURMALINE (var: Indicolite)- Paris, Oxford Co., Maine
An old specimen, ex-Michigan Mining College and originally donated by the rather famous L.L. Hubbard (b. 1849) to the school, here as a pair of pencil-thick, translucent to opaque blue crystal sections, the thicker one about 3cm long, the thinner somewhat longer one on the bottom of piece about 4cm long, each entrenched in greyish massive quartz with flakes of silvery muscovite also present. A classic Maine tourmaline, likely elbaite but perhaps foitite, often called "indicolite" based on color alone. Overall specimen size about 5.5x5cm @ 85.00. One only!

TRIDYMITE- nr. Black Rock, Millard Co., Utah
Minute druses of vitreous tridymite lightly scattered on lithophysal rhyolite, forming unusual concentric banded material from this obscure locality. This is the material featured in the February, 2016 issue of Mineral News that had been XRD confirmed some years earlier, and it is the first reported occurrence of the mineral in Millard County. Specimens range from about 5cm to nealry 10cm across at 25.00, 40.00, 65.00 and 90.00 each, depending on coverage.

TRIPHYLITE- Grafton, Grafton Co., New Hampshire
Very old material, collected by L.L. Hubbard (1849-1933) and ex-Michigan Mining College, here as coarse crystalline masses admixed with typical granitic pegmatite matrix showing greenish brown to bluish (from incipient vivianite alteration) color richly comprising these old specimens. Sizes from about 2cm to nearly 8cm across @ 7.50, 15.00, 30.00 and 55.00 each. Old stuff!

URANINITE- Shinkolobwe, Shaba, (Zaire) Dem Rep Congo
A fairly hot, mass of black uraninite scattered in rock matrix, here with minor secondary minerals evident, including dull greenish metatorbernite and sparse curite. Very old material from this famous Congo locality, ex-Cleveland Museum of Natural History, a rather flat specimen about size about 5 x 3 cm @ 185.00.

VONSENITE- Burguillos del Cerro, Extremadura, Spain
Widespread in small amounts, vonsonite occurs in this Spanish locality as rock forming, nearly pure schistlike aggregates of indistinct prismatic crystals. Dense, interesting ferrous ferric boron oxide material with a high luster, in sizes ranging from 2cm to 8cm @ 10.00 and 15.00 for the smaller samples, then 45.00 and 60.00 each for the larger.

WAVELLITE etc.- Lucin, Box Elder Co., Utah
From the famous minyulite find (see Mineral News, April, 2012 issue), these are superb, transparent and colorless glassy micro sprays of wavellite well scattered on matrix, typically as overgrowths and associations with more silky, needle-like sprays and balls of minyulite, occasionally with other phosphate species as well. Selected from a large lot of material, these are quite spectacular under the 'scope, with overall matrix sizes from about 2cm to 6cm across @ 10.00, 20.00, 35.00 and 50.00 each, depending on coverage and associations.

ZINCOBRADACZEKITE (2015-041)- Yadovitaya Fumerole, Tolbachik, Russia
Yet another NEW SPECIES from this Kamchatka volcano, here as tiny blue to bluish grey tabular to irregular micro grains on an altered basalt scoria, occasionally with hematite, K-feldspar etc. Formula: NaZn2Cu2(AsO4)3, monoclinic, IMA # 2105-041. This interesting phase is a new member of the alluaudite
group Nd the Zn-Cu ordered analogue of bradaczekite, all specimens with arrows and perched on vuggy matrix averaging 2cm across @ 165.00 each. Only a few!

BOOKS
WALKS and TALKS in the GEOLOGICAL FIELD- by Alexander Winchell (1886)
One of Professor Winchell's best known works, the "Walks and Talks in the Geological Field" was written to bring concepts and theories of geological sciences to the casual reader, "starting with observations at their front door" and proceeding into mines, metallic ore formation, the fossil record etc.. Over 325 pages, first edition hardcover, moderately good condition for its age @ just 25.00!

COLLECTIONS

AZOTIC TREATED QUARTZ - Brazil
Ever since the first appearance of "aqua aura" many years ago, there has been considerable interest (and several scams as well) in weirdly colored quartz crystals often sold as completely natural. While the crystals themselves are, indeed, natural quartz crystals, the vibrant colors available today are the result of a molecular deposition treatment first employed years ago by vaporizing gold (and now other substances) to impart color to otherwise colorless, transparent crystals. We recently acquired a rather large collection of these specimens, all as individual quartz crystals, all singly terminated, and averaging 5 cm to 6 cm tall. Colors include blues, greens, yellows, reds etc., and it appears these were originally intended as pendants, as they have a tiny, 1mm hole drilled through the non-terminated end, suitable for lacing a small wire through the crystal so that it would hang "point down" from a necklace. We offer a lot of five (5) different colored crystals at just 45.00 per lot. Orders for multiple lots welcomed: 2 lots (10 xls) for 85.00; 5 lots (25 xls) for 195.00! Crazy stuff!

GEMS
ZOISITE variety TANZANITE- Merelani Hills, nr. Arusha, Tanzania
Quickly becoming one of the most popular gemstones, we have a small lot of pale purplish blue zoisite var: tanzanites in nicely cut ovals, all eye clean and quite nice! Although you'd expect to pay up to $250 per carat in this size and quality range, we offer a low flat price for stones in the 0.70 to 1.10 carat range, @ just 70.00, 95.00, and 110.00 per stone. Larger, darker (and considerably more expensive) faceted stones available, as are good single crystals without matrix - enquire!

PETROLOGY SAMPLE
CROCIDOLITE - Bechuanaland, Botswana
A striking E.W. Heinrich specimen, museum-sized and quite impressive, comprised of densely packed fibrous blue riebeckite (variety crocidolite), an asbestiform mineral commonly referred to as blue asbestos, here as the major component of an altered metamorphic rock. The mineral is present in thick, stacked, wavy bands up to 2cm tall and completely running through the entire 15 pound (!!) sample. Heinrich's label indicates the locality as "Bechuanaland, South Africa", suggesting it was collected long before Bechuanaland became the Republic of Botswana in 1966, when it was still a protectorate under Great
Britain administration. The specimen is a monster-sized example, about 26x15x9 cm, the largest I have ever encountered, @ 300.00 plus shipping. Purported to be among the nastiest asbestiform minerals. Don't eat or breathe this one!

CATALOG 21607 – Volume XLIII, No.7

ANALCIME- Mont St. Hilaire, Quebec, Canada
We have a pair of excellent MSH analcimes, each showing well-formed, white trapeziohedral crystals of good size. The first is a 2.5cm single crystal perched in the center of an 8x6cm complex, etched greyish white crystal of microcline that shows a small (<1cm) orange serandite fragment at one edge, priced at 175.00. The second is a group of somewhat larger (to 3cm) analcime crystals intergrown into a 6.5x4cm group, with a 7mm well-terminated, redish black mangan-neptunite crystal protruding from the base, accompanied by platy polylithionite, small natrolite crystals and other attractive micro minerals as well! This one deserves greater study at only 250.00.

ANGLESITE- San Rafael Mine, Nye Co., Nevada
Small thumbnails from this prolific locality showing weird pods of greyish-white banded anglesite as banded rims replacing altered galena in matrix. Best viewed under the 'scope, these will typically show micro quartz, cerussite or possibly other species associated with these strange-appearing specimens. Only a few available @ 8.50 each.

ANILITE- Painesdale, Houghton Co., Michigan
From the 2009 find, the first analytically confirmed occurrence for the species in Michigan, we have a good selection of brilliant, metallic greyish blue to nearly black splendant aggregates and masses of anilite in seams in white quartz matrix, many with malachite and possibly other secondary copper minerals very richly scattered. XRD data on unground material shows trace admixed chalcocite but otherwise nearly pure anilite at this new surface find!!! Perhaps the richest material ever encountered for the species, the first confirmed for the state, specimens from about 3cm to monster 15cm specimens @ 20.00, 30.00, 45.00, 60.00, 75.00, 100.00, and 150.00 each. Extremely heavy! WOW!

BECQUERELITE, URANINITE etc.- Shinkolobwe, Katanga (Zaire) Dem Rep Congo
A very dense and heavy black uraninite specimen showing a number of secondary uranium minerals scattered abouts its surface, the most interesting an excellent patch of yellow laths and sprays of excellent becquerelite crystals, accompanied by minor needles of uranotile, dull greenish powdery metatorbernite, curite and possibly others. Exceptionally hot sample, ex-Al McGuinness (mcguinnessite) specimen, size about 6x3.5cm @ 495.00. One only!

BERYL- Helen Beryl Mine, Custer Co., South Dakota
A large but rather ugly cabinet specimen showing a 3.5cm pale greenish beryl mass perched at the edge of a hefty pegmatite matrix, here with a larger (6cm diameter), non-descript beryl mass embedded in obvious muscovite, quartz and feldspar matrix, along with black dendritic oxides and apparently other admixed phases revealed by spotty, preferential creamy-yellow fluorescent response under LW UV. Ex-E.W. Heinrich, and his label indicates "core margin replacement unit", likely collected by him in the 1940s. Overall size is about 12x9x9cm @ 65.00. One only!

CASSITERITE- Golconda Mine, Governador Valadares, Brazil
A small lot of pristine, vitreous black cassiterite crystal groups with little or no matrix, these thumbnails showing very sharp faces and high luster! Only a few available, old Luis Menezes material from years ago, sizes averaging about 1.5cm @ just 15.00 each. Nice!

CAVANSITE on STILLBITE- Wagholi, Maharashtra State, India
A nice lot of exquisite, electric blue cavansite in radiating crystal sprays and groups nicely isolated and perched on white stillbite crystals. Attractive specimens at less than half of what others have charged for these excellent specimens. All good quality, priced according to size, coverage, completeness and asthetics, from 2.5cm to 5x3cm @ only 30.00, 45.00, 70.00, and 100.00, a few very dense, compact balls of very deep color on 7cm matrix @ 150.00 each. Beautiful pieces!

CHALCOCITE- Flambeau Mine, Rusk Co., Wisconsin
Interesting, dark greyish blue metallic aggregates and crude crystals of chalcocite completely comprising matrix, these from the well known find of some years ago, now defunct. Someday these may rival Bristol, Connecticut specimens in pricing, but for now are still quite reasonable, with 2.5cm TN's at just 15.00 to 35.00 each, and a few larger samples to 5cm @ 50.00 to 100.00 each, depending on qulaity. Get 'em while you can..

COLEMANITE- Boraxo Pit, Death Valley, Inyo Co., California
Attractive, short prismatic monoclinic spear-shaped crystals of colemanite full covering matrix, all showing excellent form in radiating and up-standing groups. These are transparent to translucent and have a subtle, pleasing greyishwhite color. Quite exceptional when compared to the more typical blocky white specimens, these are very aesthetic and yet reasonably priced, sizes from about 2.5cm to 10cm across @ 8.00, 15.00, 25.00, 40.00 and 55.00. A few larger available - inquire!

COPPER with MALACHITE, CALCITE- Bound Brook, Somerset Co., New Jersey
A smallish hand specimen showing thin, seam-filling native copper well scattered through matrix, and with superficial green malachite, chrysocolla, and possibly dark, copper-sulfide phases as well. The piece is ex-H.E. Moore, and a handwritten note attached to his label indicates" Found in the brook opposite the quarry" and is dated October, 1946! One small saw cut face shows the dendritic patter of the native copper as well, and the overall size is about 6.5 x 4.5 cm @ just 35.00, with old labels.

MAGNESIO-HORNBLENDE- Sterling Hill, Ogdensburg, Sussex Co New Jersey
Agonizing over amphibole identifications is a painful process. We uncovered a old, small lot of nearly black, densely aggregated amphibole from Sterling, most intergrown with small patches of fluorescent calcite, occasionally with trace willemite. It took four analyses, literature comparisons with Palache, Dunn and Klein et al to determine that it is closest to magnesio-hornblende based on our analytical work. Specimens range from 2.5cm to 6cm across, priced at 15.00, 25.00, 40.00 and 55.00, each accompanied by a copy of an X-ray spectra and a copy of our comparative worksheet against edenite, pargasite etc...I hate amphiboles and rapidly changing IMA nomenclature for the group!

Interesting quartz crystal sections and faceted gemstones with tiny spines and radiating balls of pinkish red macfallite nicely scattered along a plane in the sample, some also with minute black crystals of braunite. Obtained twenty years ago from the late Carlos Barbosa, a strange and uncommon inclusion, either as quartz crystal sections of 1.5-3.5cm @ 25.00, 35.00 and 50.00 each, or as various faceted gem stones averaging 6mm to 8mm @ 45.00 and 65.00 each.

MAGNETITE- Tilly Foster Mi, Brewster, Putnam Co., New York
A monster specimen comprised of a single black mass of magnetite, extracted from this famous iron mine by the late G.Fred Lincks. The piece weighs roughly nine (9) pounds (!!) and measures about 16x9x8 cm @ 95.00. Expect extra shipping; magnetic and ugly, but a great, historical locality piece from an inaccessible, long-forbidden property.


MINYULITE- Lucin, Box Elder Co., Utah
This is the excellent material described in the April, 2012 Mineral News article. The specimens show fine, needlelike white tufts and spiney crystal groups of minyulite perched on matrix and in seams, some groups reaching 1.5cm or more in diameter! Perhaps the finest minyulite specimens ever encountered, these are rich and fairly attractive for a normally tiny species, mildly fluorescent, some with ferrian variscite, wavellite, carbonatefluorapatite, crandallite replacing fluellite and possibly other species! Specimens range in size from about 2cm to 8cm across, very reasonably priced at just 10.00, 20.00, 35.00, 50.00 and 85.00 each. Superb, and likely "best of species" material! A few monster specimens available - inquire!

NABAPHITE- Kukisvumchorr Mt., Khibiny, Kola Peninsula, Russia
Dull white massive material for this extremely rare species sparsely scattered on matrix. Only a few small samples on hand, typically averaging about 5mm across @ 135.00 each. Only a few, so please list alternate selections!

NCHWANINGITE- N'Chwaning Mine, Kalahari Mn Field, Rep. So. Africa
This rare species, a hydrous Mn-silicate, occurs as minute, slender transparent colorless crystals on quartz, some groups having a pale brownish cast. A few superb micro balls of radiating crystals, overall sizes are tiny, averaging <1mm @ 125.00 and 150.00 each. Excellent micro material!

ORPIMENT- Palomo Mine, Castrovirreyna, Peru
Excellent, deep orange to yellow-orange micro crystals and botryoids of orpiment nicely covering matrix, many with micro red realgar crystals and/or barite. Not your typical, flakey material, common sulfides here include potential sphalerite, seligmanite and others, and the mine is the type locality for the orpiment dimorph anorpiment as well, described in 2011. Colorful and attractive specimens, sizes ranging from about 5cm to 7cm across @ just 35.00 and 55.00 each. Only a few on hand!

PAOLOVITE with NIGGLIITE- Oktyabr Mine, Norilsk, Siberia, Russia
Small metallic masses that have been microprobed to confirm identification, each accompanied by a SEM backscatter image as well as the X-ray sectra for both paolovite and accompanying niggliite. A rare combination of palladium-tin and platinum-tin species, only one available at 250.00.

RINGWOODITE- Tenham Station, S. Gregory, Queensland, Australia
This very rare mineral has been found almost exclusively in meteorites or as minute inclusions in diamonds, and then only by careful microprobe study. We have an elegantly documented sample consisting of a 1cm polished square containing a minute (<1mm) thin sectioned sample from the type locality, the Tenham Meteorite, a hypersthene-olivene chondrite (L6, S4). The meteorite fell in the Spring of 1879, and our microprobed sample is accompanied by a color SEM image as well as full chemical composition. Associations in the sample include plagioclase, as well as kamacite and troilite. First come-first served @ 375.00; list alternates!

SARTORITE- Lengenbach Quarry, Binnental, Valais, Switzerland
Good quality samples of this rarely offered material, type locality of course! Sartorite occurs as steel grey to bluish tarnished platy to foliated masses in white, sugary dolomite matrix, some occasionally with associated red realgar. Specimens from 1cm to 4cm @ 20.00, 35.00, 50.00 and 75.00 each.

SEARLESITE- Cave Springs Borax Deposit, Esmeralda Co., Nevada
This uncommon species occurs as minute, transparent to translucent glassy aggregates and micro crystals sparsely scattered in seams in pale boraciferous marl matrix. Excellent for the locality as desccribed by Foshag in American Mineralogist in 1934 (Vol. 19, pg 268-74), specimens range from 2cm to nearly 5cm @ 20.00, 35.00, 50.00 and 75.00 each, depending on coverage and size.

SILVER- Crown Reserve Mine, Coleman Twp, Ontario, Canada
A significant example of native silver from this locality, here as numerous streamers and dendrites richly scattered in an uncommon pink calcite matrix, including minor nickeline and skutterudite, likely with trace acanthite as well. This large specimen has one face cut flat to expose the dendrites, and it is accompanied by a handwritten letter from one Arrian Parcher in Cobalt to John Durkos, the former specimen owner, in 1970. The letter describes the beds of slate greywacke that yielded the specimen and attests to the rarity of pink calcite as a host for the native silver. A monsterous beast, weighing over 7 pounds (!!!) and measuring about 23x11cm on its face, offered at 425.00. The piece would likely take a good sanding and polishing if so inclined.

TARANAKITE- Super Cave, Cervantes, W.A., Australia
Dull white, small nodular masses of this uncommon mineral scattered in loose quano-soil matrix. Decidedly ugly stuff but from an unusual locality, available in 2cm capsules @ 20.00 each, or in 4cm glass vials @ 45.00 each.


TENNANTITE with GALENA- Dos de Mayo Province, Huanaco, Peru
Tiny, metallic greyish black micro aggregates of tennantite intergrown with unusual, brilliant druses of galena richly comprising matrix, most with platy white barite and/or small beige rhombs of siderite and/or crude sphalerite. Interesting and moderately handsome specimens, sizes average about 7cm across at just 35.00 each. Only a few !

URANOPILITE with COFFINITE etc.- Atlas #9 Mine, Tidwell Draw, Emery Co. Utah
Collected over 20 years ago from this obscure locality, these specimens are comprised of bright yellow uranopilite (fluorescent green under SW UV) associated with coffinite, slightly darker yellow tyuyamunite and disseminated uraninite, with other phases possible. The stratified matrix is moderately radioactive, as expected, as are much of the uranium/vanadium deposits in the area. Specimens range from 2cm to 6cm @ 10.00, 20.00 and 35.00 each; one considerable larger 12x7cm sample @ 75.00.

VOLKOVSKITE- Boulby Mine, North Yorkshire, England
This rare borate mineral is a member of the veatchite group, and it is found at only a handful of localities worldwide. This specimen is a very thin, transparent crystalline platelet about 2x1cm in cross-section with a bare trace of pinkish hilgardite (?) providing a hint of color. Only one specimen available @ 125.00. List alternates!

WINDHOEKITE- Aris Quarry, Windhoek District, Namibia
This relatively new mineral occurs here at the type locality as excellent, micro needles in radiating sprays perched in vugs in rock matrix, all with a golden brown hue and very attractive under the scope. We analyzed a large number of tuperssuatsiate samples we had in stock (all visually indistinguishable from this species!) and found only five (5) specimens that were this new, Ca-dominant member. Every numbered sample will have its own individual analysis included, and the specimens average about 3cm across at 200.00 each. Limit one per customer, please, and if you plan to get one elsewhere, be sure it is a specimen with the actual chemical analysis, as there is no apparent difference in X-Ray pattern or physical appearance between this species and the apparently more common tuperssuatsiatite! Caveat emptor!

GEMS
TOPAZ - "Swiss Blue" Brazil
Excellent, faceted Brazilian topaz in an unusual 10mm heart shape, these are heat treated to yield a superb "Swiss Blue" color that is the most desireable of topaz hues. Well-cut, gemmy and fully transparent and eye-clean stones average over 4 carats each @ just 30.00 per stone, or a matched pair at 55.00. Very attractive!

BERYL (Red: variety "Bixbite")- Violet Claims, Millard Co., Utah
A superb single crystal of classy red beryl, here as a well formed, 2cm tall bright, pinkish red single crystal showing a perfect pinacoid termination, a smaller crystal perched on that pinacoid, and sharp hexagonal prism faces that are lightly encrusted with greyish-white rhyolite.The top of the crystal is quite gemmy, and we have made no further effort to remove the rhyolite from thr prism faces. Excellent sample, this one quite large for the variety, at 950.00. A few small crystals available, sizes from about 6mm to 9mm tall @ 125.00 and 150.00 each. Excellent color!

BRUCITE- Asbest, Ural, Russia
An excellent specimen comprised of thick bands of white, chatoyant brucite about 8mm thick running through the entire length of this 5cm specimen. A classic locality for the species, only one available, @ 75.00.

CALCITE- Logansport, Cass Co., Indiana
Pale, slightly yellowish hued calcite single crystals, most with little or no matrix, all showing excellent trigonal terminations atop rather stout prismatic crystal forms. The diaphaneity on these ranges from transparent to translucent, and the color is attractively subtle. From an old lot, ex-A.E. Seaman Mineral Museum, sizes range from about 2x2cm to 4cm across @ just 6.00, 10.00 and 15.00 each.

CALCITE on STILBITE- Los Mochis, Sinaloa, Mexico
A handful of these from the Jean Hamill collection recently came to light in our warehouse, and they are wonderfully hued, amber-brown translucent to transparent rhombic crystals to 1.5cm nicely perched on druses of micro white stilbite, the latter mineral never reported on Mindat from this location before. The locality was originally labeled as "Ciruela", a non-existent town, but subsequent labels indicate "Los Mochis" as the location, lying just to the NE of Rio de Culiacan, the only reported occurrence (Salinas, 1923) of stilbite in Sinaloa. It is likely that the original find is somewhere between these two towns along the Sinaloan coast. Only a couple of attractive specimens on hand, most in the 6cm size range at just 40.00 each. See Mindat images for color!

CHEGEMITE- Lakargi Mt., Upper Chegem Caldera, Russia
This relatively new mineral was described from this, the type locality, in 2008, and occurs as abundant pink, transparent grains to several millimeters scattered in a greenish-white matrix of calcium hydrosilicates. Found in Xenolith No. 1 in this Northern Caucasus deposit, we have only a few small TNs available @ 95.00 each. List alternates!

CHENEVIXITE- Wheal Gorland, St. Day, Cornwall, England
Old specimens comprised of dull yellowish green crusts of chenevixite richly scattered over most of the surface of these fairly ugly matrix specimens.

CHLORAPATITE- Odegardensverk, Bjordam, Telemark, Norway
Massive crystalline cleavages of chlorapatite scattered in matrix, occasionally associated with talc, enstatite etc, although having a decidedly non-apatite appearance. The color of the nearly pure material ranges from pale olivegreen to white to pale pink, and has a greasy to dull luster on some, almost vitreous on others. In sizes from 2 cm to 5 cm priced at 20.00, 35.00 and 45.00 each, depending on size.

CROCOITE- Berezovsk, Sverdlovsk, Ural Mts., Russia
From ancient stock in our warehouse, a few representative examples of type locality crocoite, here as small, deep orange-red crystalline masses lightly scattered in flattened sprays and aggregates on massive quartz-rich matrix. Recently featured in Mineralogical Record, these are not killer cabinet specimens at unreachable prices, but rather typical mine-run examples from this classic deposit rarely available today. Specimens average about 4cm across @
just 55.00 each. Old stuff!

CUSPIDINE- San Vito Quarry, Vesuvius, Italy
A great combination of nice micromount and fluoresecent material, cuspidine is found as 1 mm-sized beige chisel to spear shaped distinct, beige microcrystal clusters, scattered in a vuggy vesuvianite matrix and associated with other fluorescent and non-fluorescent minerals such as humite, phlogopite etc. The type locality for cuspidine is the nearby Mt. Somma section of Mt. Vesuvius. In matrix sizes from 2.5cm to 5cm @ 20.00, 45.00, and 60.00.

DIAMOND- Paragua Region, Bolivar Province, Venezuela

EITELITE- Westvaco Mine, Sweetwater Co., Wyoming
This rare Na-Mg carbonate occurs here as somewhat columnar, waxy aggregates of pale yellow-brown color largely comprising matrix, apparently from a single seam within this prolific Green River formation locality, best known for its loughlinte and shortite specimens (yes, we have those as well). Sizes average about 3cm tall @ 75.00 each. Only a few available!

GADOLINITE-(Y)- Iveland, Aust-Agder, Norway
Rich, brownish black greasy to vitreous masses of this rare-earth species richly comprising matrix, numerous pieces filling a 4.5cm stoppered glass vial. Old material that was recently analyzed in our lab, each vial complete with a copy of our analysis (SiO2 distorted due to lack of beryllium detection by EDS) that shows a surprisingly high dysprosium content @ just 20.00 per vial.

GIRDITE- Grand Central Mine, Tombstone, Arizona
Dull white masses of this rare tellurate sparsely scattered on matrix, these original obtained from the author, Dr. Sid WIlliams, shortly after its description. Only a few small specimens on hand, typically 1cm to 1.5cm @ 75.00 and 100.00 each, depending on coverage.

GRAESERITE- Gorb, Lercheltini, Binntal, Wallis, Switzerland
This rare arsenite mineral occurs here at the type locality as extremely small, black rod-like needles sparsely scattered in a well-crystallized mica-rich gneiss. In 2006, yours truly co-authored the description from the only other known locality in the world for this mineral (see Mineral News, Vol. 22, no. 9 - 2006), at Sterling Hill in New Jersey. Only a couple of type locality specimens available, matrix sizes averaging about 5cm long @ 125.00 each.

HALLOYSITE- Concan Mine, Uvalde Co., Texas
Your basic non-descript but representative mineral, and one of four hydrous aluminum silicate polymorphs, halloysite occurs here as chalky to powdery white to tan masses richly scattered in/on matrix. Perfect for the systematic collection, halloysite can be had in sizes from 2cm to 3.5cm @ 15.00, 20.00 and 25.00 each. Off-beat locality!

HAUYNE- Valle Biachella, Scarofano, Roma, Italy
Greyish to pale blue crystals and aggregates of hauyne richly spread in greenish pyroxene matrix. Nicely FLUORESCENT pale orange-pink (LW best), from 2cm to 4.5cm @ 15.00, 25.00, 35.00, 45.00 each.

HENMILITE- Fuka, Okayama Prefecture, Japan Deep blue grains of this rare copper borate to 0.2mm dispersed in white calcite matrix with various calc-silicates, most typically with pentahydroboroite, these from the type (and only!) locality. Specimens are small, ranging up to
0.5cm matrix samples @ 65.00 each.

HOWLITE on ANHYDRITE- Bras D'Or Lake, Iona, Nova Scotia, Canada
From the finest (and perhaps only) occurrence of truly well crystallized howlite in the world, these are small groups of this unique anhydrous Ca-B-silicate found as greyish to pale brown radiating crystal groups to 2cm across perched on massive anhydrite matrix. The individual monoclinic spears are the finest of the species which is normally found primarily as massive or chalky botryoids. A rare occurrence, specimens ranging from 3cm to 7cm across, typically with one group and only rarely as multiples. priced according to quality, not size, @ 45.00, 65.00, 95.00 and 125.00 each for the best.

LAUMONTITE variety LEONHARDITE- Pine Creek Mine, nr Bishop, Inyo Co. Califo

OPAL- Mintabie, South Australia, Australia
Handsome matrix specimens consisting of dense, white Ordovician sandstone with veins or exposed surface seams of firey, white-based opal, showing blue, orange, yellow and green flashes. The material is also nicely fluorescent (LW:UV-blue white) and shows an uncommon and long-lasting phosphorescence as well. Specimens range from reference pieces to rich, gemmy exposures, overall sizes from about 7x6cm to 17x8cm, priced at 45.00, 75.00, 100.00, 150.00, 200.00 and 300.00 each, depending on size and firey opal exposure. Free with each specimen: a copy of the April, 2015 Mineral News article that more fully described the locality and acquisition of these interesting specimens!

PECTOLITE- Paterson, Passaic Co., New Jersey
A rather appealing, baseball-sized specimen of radiating white pectolite, delicately exposed as a broad seam of nicely terminated crystals that are capped by a secondary (?) overgrowth of slightly greyish pectolite, making for an attractive and contrasting combination. A little rock matrix surrounds two sides of the piece, and it measures about 7x6x6cm and displays from several directions. An old and fairly attractive sample, collected circa 1950 and ex-H.E. Moore Collection @ 125.00. One only!

PERETAITE- Pereta Mine, Grosseto, Tuscany, Italy
Fine microcrystals of this secondary antimony mineral! Peretaite is found as transparent to almost opaque elongated and flattened lath-like microcrystals in altering stibnite, associated with sulfur microcrystals and dull red metastibnite, kermesite etc. Each specimen contains as least one area of nicely formed crystals, available as 2cm to 5cm matrix specimens @ 20.00, 35.00 and 55.00 each. Good micro stuff!

PERITE- nr. Benson, Cochise Co., Arizona
Extemely small, bright yellow masses and filmy aggregates of this unusual mineral sparsely scattered on the surface of copper-bearing quartz, some with minor chrysocolla. Magnification required to see the tiny aggegates, overall matrix sizes from 2.5cm to 7cm @ 20.00, 35.00, 50.00, 75.00 and 95.00 each, based on size and coverage. Lean and ugly stuff!

PHOSPHOHEDYPHANE- Coeur d'Alene Dist., Shoshone Co., Idaho
These are rather stange looking hopper crystals of tan to brown phosphohedyphane, collected in the 1960s by Ted Morley of Piedmont Minerals. At the time, these were known as “polyspaherite", believed to be a calcian pyromorphite. Work on similar Chilean material led to the new species description in 2005 by Kampf et al. Sadly, the mine these came from was never revealed, and whether these are pseudos after pyromorphite or just cavernous, crystallized phosphohedyphane is unknown. A typical specimen was pictured in the June, 2016 issue of Mineral News, and we have a few TNs and small groups from 1.5 cm to nearly 5cm @ 15.00, 25.00, 45.00 and 55.00 each.

PREHNITE- Paterson, Passaic Co., New Jersey
A fairly large selection of older specimens, many from a small university collection recently obtained. Colors of these prehnite specimens ranges from pale green to murky, darker material, habits typically botryoidal but also as thickly intergrown, small wedge-like aggregates from the 1930s nicely covering matrix. Recently featured in Mineralogical Record, we have a good selection of these classic samples, sizes from TNs to 10cm @ just 5.00, 10.00, 20.00, 35.00 and 55.00 each.

PUMPELLYITE-(Mg):CHLORASTROLITE- Isle Royale, Keeweenaw Co., Michigan
This uncommon pumpellyite group mineral is Mg-dominant and is often found as rounded, amigduloidal fillings, often showing a spider web pattern in the chlorastrolite variety that was discovered here in 1847, later described by Palache et al in 1925 and redefined by the IMA in 1973. We offer a 2cm stoppered glass vial containing over a half dozen rounded amygdules at just 12.50 per vial. Limit 2 vials per order, please.

QUARTZ- Aiguille D'Arves, Savoie,Rhone-Alpes France
Transparent quartz crystals to 1.5cm nicely perched on matrix of smaller quartz crystals, all nicely terminated and occasionally with a pale yellowish iron staining.

RHODOCHROSITE- American Tunnel, nr. Silverton, Colorado
A recently uncovered older lot of pale pink rhodochrosite, here as rhombic crystals nicely intergrown and occasionally perched on quartz/sulfide ore matrix. Attractive small specimens, sizes from about 1.2cm to nearly 3cm @ 10.00, 15.00 and 20.00 each. One exceptionally large cleavage specimen showing solid rhombohedral form, ex-University of Arizona and accompanied by their label, a solid 5.5 x 4 cm crystal specimen @ 300.00. List alternates.

SCHOEPITE ps @ RUTHERFORDINE- Musonoi Open Pit, Shaba,(Zaire) Dem Rep Congo
Complex and colorful specimens: bright yellow,spear-shaped micro crystals and groups of schoepite occur here largely as pseudomorphs after tan aggregates of rutherfordine. Associations vary but often include other colorful uranium minerals typical of the locality (uranophane, cuprosklodowsite etc.) with significant amounts of malachite, hematite, and digenitic rock on most specimens. Attractive specimens with terrific micro potential, these are priced
according to coveage and aesthetics more than size, with specimens from 2.5cm to 5.5cm @ 55.00, 75.00, 100.00, and 125.00 each. Uncommon pseudomorphs that are moderately hot as well, and easily visible but really superb under the scope!

SEGNITITE- Gold Hill, Tooele Co., Utah
From the only confirmed occurrence of the species at this prolific mine, this material was collected from a single pocket in the Glory Hole over 20 years ago and has recently been XRD and EDS confirmed (see May, 2016 issue of Mineral News). The mineral occurs as greenish yellow, somewhat earthy crusts richly scattered in/on micro boxwork structures, typically associated with minor scorodite and quartz. A unique find, only the second for the state of Utah, specimens from TNs to 6cm @ 10.00, 25.00 and 45.00 each. Not pretty, but certainly interesting!

SMITHSONITE- Kelly Mine, Magdalena, Socorro Co., New Mexico
Most mineral collectors know of the superb, blue-green botryoidal smithsonites from this famous locality that command incredibly high prices,, but these are NOT those smithsonites! Rather, they are a delicate greyish to very pale bluish hue, presented as thin botryoids on matrix, some with small black splotches of manganese oxides or light overcoatings of mildly fluorescent calcite. Interesting old material, collected circa 1958 and offered as representative specimens from about 2cm to 5cm across @ just 7.50, 15.00 and 25.00 each.

SYNCHYSITE-(Y) (DOVERITE)- Scrub Oak Mine, nr. Dover, Morris Co New Jersey
Dark brick red masses of synchesite-y speckle a matrix of dark greyish black magnetite ore on these massive granular samples from the type locality. Originally called "doverite" due to the Mine Hill Borough's proximity to the adjacent town of Dover. Collected by your's truly over 30 years ago while residing there! Sizes from 1cm to 5cm @ 8.50, 15.00, 25.00, and 40.00. A few larger samples available to 8cm @ 65.00. Impossible to find this type locality
material today!

TURQUOISE- Zhilandy, Maikain Deposit, Kazakhstan
From the 2006 find, these are exceptionally attractive nodules of bright blue turquoise, some showing attractive dark brown rims and a variety of spider-webbed color bands and circles of various shades of blue. These have been neatly sliced and are professionally polished nodule halves with rough exteriors on one side and beautiful blue turquoise on the other! From a fairly obscure locality, these colorful nodules range from about 2cm to 3.5cm across, priced according to aesthetics and size @ 40.00, 50.00 and 60.00 each.

VAUQUELINITE with CROCOITE- Berezovsk, Sverdlovsk, Ural Mtns. Russia
This interesting specimen consists of a 3.5 cm wide, milky white quartz vein which bears numerous, deep orange, often crude crocoite aggregates (to 1cm) on the vein quartz. The rare Pb-Cu chromate-phosphate species vauquelinite also occurs in direct association with the crocoite, here as two different forms, the first and most noticeable being bright yellowish green concentric crusts and mammilary encrustations, the second form is as exceedingly minute greenish-black crystals that form a druse on the outermost surface of the mammillary vauquelinite in an open space with a tiny but well-terminated small crocoite crystal. This is the type locality and a Dana classic locality for both crocoite and vauquelinite, recently featured in Mineralogical Record, giving added appeal to this piece. Specimen size is about 6x5x4 cm cm @ 150.00.

YAROSHEVSKITE (IMA 2012-003)- Yadovitaya Fumerole, Tolbachik, Kam. Russia
We have been able to obtain a few more of these extremely rare specimens, collected by the authors from this type locality volcano! The mineral occurs as minute, lustrous black prismatic crystal aggregates delicately perched on bright green euchlorine, occasionally with altered chalcocyanite. Formula: Cu9O2(VO4)4Cl2 - triclinic. Small matrix specimens a few millimeters across @ 150.00 each. List alternates!

ZINCITE with FRANKLINITE- Franklin, Sussex Co., New Jersey
A very dense and heavy hand specimen comprised of deep red zincite richly scattered among small, countless black franklinite octahedra and rounded aggregstes. What makes the specimen of great interest is the H.E. Moore label that accompanies it, indicating that Moore collected it from the area where ore was loaded on barges on Raccoon Island. A quick review of the literature indicates that iron ore was commonly transported on Lake Hopatcong (the location of Raccoon Island) as early as the 1860s when the Ogden Mine Railroad was constructed. Certainly an interesting find for Moore of a Franklin specimen apparently found far from home, reflecting on the mining and transportation history of the area! The specimen measures a very heavy 6x5cm @ 40.00.

GEMS
LEMON CITRINE- Brazil
These are well-faceted, eye-clean gemstones of a pale yellow color, nothing like the deep orange, heat-treated material commonly seen in the mineral trade. We have a modest lot of a few hundred carats of these lightly hued gems, and most stones are ovals with a few other occasional shapes, and these gems broadly average about 10 carats each. We would like to move these quickly, so we are offering a 50 carat lot for just 45.00 per lot, or 100 carats for just 85.00, less than a buck a carat!! Limit of two lots per order, please.

ALLOPHANE- Juanita Mine, Socorro Co., New Mexico
Attractive, pale blue botryoids of allophane richly scattered on matrix, occasionally with white, bladed calcite, barite
or possibly other minerals. Old material, collected in 1958 at this well-known Magdalena District locality, with rich
coverage and color, specimens from about 2.5cm to 5cm across @ just 7.50, 12.50 and 20.00 each.

ANAPAITE- Prats-Sampsor, Lerida, Spain
This phosphate mineral is found as drusy micro crystals lining vugs in Miocene concretions. Each nodular matrix is
internally hollow, and has been broken roughly in half to reveal the olive-green, nearly transparent sharp
microcrystals of anapaite covering the inner surface. Excellent mounting material as well as hand specimens,
matrix halves from 3cm to 5cm @ 20.00, 35.00, and 45.00 each. Classic!

ANDERSONITE- Slick Rock, San Miguel Co., Colorado
BRILLIANTLY GREEN FLUORESCENT material, nicest we've seen in some time, these andersonite samples were
sold to us by a Colorado dealer some years ago as the new mineral CEJKAITE. Our chemical analysis confirms a
consistent and distinct calcium peak (hence, andersonite, not cejakite), proving once again that anyone can take a
ride buying rare minerals, even your's truly! Fine fluorescent samples with good micro potential, each including a
copy of our analysis completed in years past, sizes from 2.5cm to nearly 6cm @ 12.50, 20.00 and 35.00 each.

ANDRADITE- Stanley Butte, Graham County, Arizona
From an old find many years ago, we have a small lot of excellent, oddly colored greenish andradite garnets to 1cm
or more, most closely intergrown and showing fine dodecahedral faces in these colorful specimens. Old material
collected many years ago. Overall sizes range from about 2.5cm to 6cm @ 7.50, 15.00, and 25.00. A few
significantly larger speimens, 10cm to 20cm @ 50.00, 75.00 and 100.00 each. Big but sometimes ugly monsters!

BADDELEYITE with CORUNDUM- Bear Trap Claim, Gallatin Co., Montana

showing a perfect pinacoid termination, a smaller crystal perched on that pinacoid, and sharp hexagonal prism
faces that are lightly encrusted with greyish-white rhyolite.The top of the crystal is quite gemmy, and we have made
no further effort to remove the rhyolite from thr prism faces. Excellent sample, this one quite large for the variety, at
950.00. A few small crystals available - inquire.

BRUCITE- Jeffery Mine, Asbestos, Quebec, Canada
Long, pale green fibers of XRD-confirmed brucite without matrix, these extracted from a large seam. The mattered
fibers from thick rods and range from 5cm to 30 cm long, all matrix free, and are offered at just 10.00 to 65.00
depending on overall fiber length. All sizes available!

GALENA- Obira Mine, Oita, Kyushu Region, Japan
From an unusual and rarely offered locality, we have a few reference specimens of cubic galena, here as small
aggregates and crystals perched in sphalerite-rich ore matrix. There are likely other phases here (over 50 are
known from this copper-zinc-tin deposit), but lack of material makes further analytical work difficult to justify.
Specimens each have a Japanese-character label and range from 3.5cm to 4cm @ just 15.00 each. List
alternates!

GEARKSUTITE in PACHNOLITE- St. Peter's Dome, El Paso Co., Colorado

vugs in massive pachnolite-bearing matrix. Old material from many years ago, specimens range from about 2cm to
nearly 5cm across @ 20.00, 35.00 and 55.00 each depnding on size and coverage.

GEOCRONITE- Kilbrecken Mine, County Claire, Ireland
Grey metallic masses of this sulfosalt scattered in matrix, most associated with minor sphalerite. Named for the
Greek words for antimony and lead, these are rather ugly samples from an old Dana locality. Sizes from about 2 cm
to 5 cm at 15.00, 30.00, and 50.00 each.

GMELINITE-Na- Prospect Park, Passaic Co., New Jersey
Old material, collected circa 1940, comprised of translucent pinkish crystals nicely scattered on matrix, with some of
the better specimens associated with white datolite and possibly other phases. From the Howard Moore Collection,
samples range from about 3.5cm to 7cm across @ 20.00, 45.00 and 75.00 each. Colorful!
GRANDIDIERITE- Andrahomana, Madagascar

have seen variously labeled as "Vohibola", "Andrahomana" or "Mobetsu" as to the precise locality, these all fairly
old specimens collected about forty years ago. Specimens range from about 1.5cm to nearly 3.5cm @ 25.00, 40.00
and 60.00 each. Limited availability!

HECTORITE- near Hector, San Bernardino Co., California
Pure, porcelaneous-like sectile masses of off-white hectorite, without matrix. These substantial specimens are from
the namesake locality, and of course are representative of this clay forming mineral, a Na-dominant smectite. In
sizes from 1cm to 4.5cm, nicely priced at 15.00, 30.00, and 50.00 each. Pure available material @ $6.00 per gram.

From a small find on Valentine's Day in 1992 in a marble quarry at this uncommon locality, we have several TNsized
specimens showing interesting micros of dark green malachite, habits ranging from small botryoids to more
crystalline sprays on matrix. Certainly an uncommon eastern U.S. locality and from an older find, these are selected
samples primarily suitable for micromounting, with matrix sizes from about 1.5cm to 2.5cm @ just 7.50 each, or as
bonus lots of four (4) for just 20.00 per lot! Get 'em while you can!

MEIERITE (IMA 2014-039)- Gun Claim, Wilson Lake, Yukon Terr., Canada

quartz/hedenbergite matrix, often with dull red gillespite evident as well. Formula: Ba44Si66Al30O192Cl25(OH)33 -
isometric, IMA #2014-039. Type locality, of course, specimens average 2.5-3cm @ 125.00 each. Only a few
available; list alternates!

MILLERITE- Demoliaki Mine, Laurion, Attica Pen. Greece
Tiny, elongated needles of brassy millerite very sparsely scattered on minute, rhombohedral dolomite crystals in
exposed vugs in rock matrix. Some of the needles show alteration to an unspecified green phase, perhaps
honessite, or jamborite or ?. A rare mineral for Greece, and specimens range from about 2.5cm to 5cm across,
but are priced based on quality and aesthetics of the millerite groups under the 'scope, from tiny singles to
divergent crystal sprays at 25.00, 40.00 and 55.00 each.

NACRITE with CASSITERITE, QUARTZ- Huanuni Mine, Oruro Dept., Bolivia
Nacrite occurs here as very tiny, pearly white platy aggregates sparsely scattered among excellent, brilliant black
cassiterite crystals that are richly scattered over transparent, small quartz crystals. From the same locality as my
namesake mineral, certainly more enticing for the cassiterite, these are nonetheless quite brilliant and attractive
specimens, overall sizes about 6x3.5cm @ 65.00 each. Only a few available!

PARADOCRASITE- Moctezuma, Sonora, Mexico
Minute silvery masses of this extremely rare species richly scattered in duller grey stibarsen matrix. Confirmed by
both X-Ray and microprobe, we have just a few of these very rare specimens, sizes from 3mm to 6mm across @
45.00, 75.00, and 125.00 each. List alternates!

PECTOLITE variety LARIMAR- Los Checheses, Barahona Province, Dominican Repu
From a large lot of material collected in 1976 at the locality by well-known gem expert Joel Arem, we have
reference specimens of this strange material, here as pale blue masses and fibrous, radiaiting veinlets of copperrich
pectolite lightly scattered in a rather ugly, greyish and punky limestone matrix. We've analyzed the material (it
is, indeed, pectolite), and even polished a few samples for ourselves (they improve dramatically with cutting and
polishing), but these are essentially weird geological reference pieces of this unique material known only from this
locality, sizes from about 2cm to about 5cm @ just 10.00, 15.00, 25.00 and 40.00 each.

POLYLITHIONITE- Mont St. Hilaire, Quebec, Canada
A representative sample comprised of numerous tabular crystals of silvery white polylithionite, aesthetically
intergrown and comprising matrix. A good display piece and well-crystallized specimen, overall about 3.5m @
75.00, or a few smaller TN/micro samples to 1.5cm on hand at 25.00 each.
PURPURITE- Usakos, Karibib, Erongo Region, Namibia
These are very colorful specimens of this Mn/Fe phosphate mineral, here as bright magenta/purple masses
covering the surface of non-descript brownish-green phosphate matrix. Fairly rich unanalyzed material, specimens
average about 3.5cm @ just 12.50 each. A bargain!

SERPIERITE- Jackrabbit Mine, Lyon Co., Nevada
Featured in the May, 2015 issue of Mineral News, we have a small selection of bright blue, micro laths of serpierite
lightly scattered on matrix. Uncommon at this relatively obscure locality, fewer than a dozen samples of this
interesting copper mineral were found. Colorful and with modest micro potential as well, matrix specimens from
3cm to 6cm @ 10.00, 20.00 and 30.00 each, priced according to quality and not necessarily size.

SWINEFORDITE- Foote Mine, Kings Mt., Cleveland Co North Carolina
Decidedly ugly stuff, swinefordite occurs here as dull, dark greenish waxy masses scattered on the surface of rock
matrix. Type locality material collected many years ago from this prolific mine. An uncommon member of the
smectite group, specimens from 2cm to 5cm @ 15.00, 25.00, 40.00 and 60.00 each.

TINSLEYITE- Cerro Mejillones, Antofagasta Prov., Chile

ranging from about 2cm to 3cm across @ 75.00 and 100.00 each. List alternates!

TOOELEITE- U.S. Mine, Gold Hill, Tooele Co., Utah
This rare mineral occurs here at the type locality as tiny orange crusts and radiating aggregates sparsely scattered
on arsenopyrite/scorodite assemblages. Recently uncovered in an old parcel from Dr. Sidney Williams who first
described the species with Fabien Cesbron in 1990, we have only a few samples available, priced according to
coverage, with matrix sizes ranging from about 1.5cm to 5cm across @ 75.00, 100.00, 150.00 and 200.00 each.
List alternates!

Limited availability!

VANOXITE with METASCHODERITE- Van Nev San Claim, Eureka Co., Nevada
A pair of rather ugly minerals, here with black, fine-grained vanoxite lightly scattered in/on grey rock matrix, most
specimens associated with minor, pale yellow metaschoderite, this being the type locality for the latter phase. An
interesting assemblage from a well-documented locality, specmens from about 2cm to 4cm @ 20.00, 30.00 and
45.00 each.

WULFENITE- Mianning, Sichuan Province, PR China
An interesting locality for wulfenite, these occurring as rich, bright orange micro crystals in stout, truncated
pyramids and nearly equant crystals very nicely scattered over matrix, many with micro bladed barites as well!
Exceptional micro potential from this new find, all quite colorful and attractive! Specimen sizes range from about
3.5cm to 5.5cm @ 20.00, 30.00, 40.00 and 50.00 each. Don't miss these, as they were some of the first wulfenites
coming from China in the late 1990s!

YUKSPORITE- Mt. Yukspor, Khibiny, Kola, Russia
Pink fibrous masses of this unusual species richly scattered in matrix, associated with minor white pectolite,
microcline and occasional aegirine, all accompanied by copies of a Czech National Museum label. Type locality,
matrix sizes from 1.5cm to 4cm @ only 10.00, 20.00 and 35.00.
BOOK

MOONSTONE- Sri Lanka
Excellent transparent to translucent moonstone cabochons, all showing sharp and distinctive shiller effects
commonly called adularescence. Mineralogically, these are predominantly orthoclase with admixed albite, and the
alternating layers of the two feldspars are responsible for the light interference and shimmer seen in this material.
We have a variety of shapes and sizes, most either rounds or ovals that are all well-polished, and the stones
range from about 5 carats to 12 carats in weight. We offer these only in lots of 10 stone assortments, typically
weighing about 70 carats per lot, for just 30.00 per lot, a steal at less than 50 cents a carat!! Limit no more than

Neat specimens with many micro crystals evident, sizesfrom 2cm TNs to 7cm hand specimens @ just 5.00. 10.00 and 20.00 each.

CLINOCHLORE etc.- Bull Run Quarry, Loudoun Co., Virginia
Small green aggregates of analytically confirmed clinochlore nicely scattered in vuggy white albite matrix, typically with several other associated minerals in micro crystals. The locality boasts over 30 different species, and these are quite nice under the 'scope. Rich specimens in the 2cm size range at just 7.50 each, including a copy of our analysis, and if you are an avid micromounter who likes to hunt through rich material, we can offer a lot of twenty (20) samples in the 1-2cm size range for just 55.00 per lot of 20 specimens! What a deal!

CONICHALCITE- nr. Imlay Canyon, Pershing Co., Nevada
Apple green dustings of this prolific copper mineral lightly scattered on massive milky quartz from this unnamed prospect near Imlay Canyon. While not a rare or exciting mineral, These show some decent color and modest micromo potential and are from a reasonably obscure deposit. Specimens are 2.5cm to 3cm across @ just 5.00 and 7.50 each, depending on coverage.

DEVILLINE in GYPSUM- Bou Bekker, Toussit, Jerada Prov., Morocco
Attractive, pale blue masses of devilline richly coated and contained within transparent, water-clear gypsum balls, offering a vitreous luster in good contrast to beige dolomitic matrix. Previously noted as malachite or rosasite by others, we have sacrificed a sample and analytically confirmed these as devilline, and a copy of our EDS spectra is included with each sample. Specimens average 5cm across @ 55.00 each. Quite attractive!!

DIAMOND (1.34 cts)- Tshikapa, Kasai Province, Dem Rep Congo
This rich alluvial deposit along the Tshikapa river has produced many interesting diamond crystals over the years, this one being a bright yellow, frosted, translucent cube about 5mm on edge, showing fine luster and color, with many face steps contributing to the apparent high luster of the crystal. Only one available, 1.34 carats, @ 135.00.

DIOSKOURIITE (IMA 2015-106)- Arsenatnaya fumerole, Tolbachik, Kam Russia
This NEW SPECIES occurs as minute, single grey grains mounted on 1cm stubs. Formula: CaCu4Cl6(OH)4*4H2O - monoclinic 0 IMA # 2015-106. The mineral has intergrowths of its unnamed, orthorhombic polytype, and its name is cleverly derived from Greek mythology for Dioskouri, the inseparable twin brothers. Type locality material, of course, tiny mounted samples @ 120.00 each. Limited availability!

FILIPSTADITE- Jacobsberg, Filipstad, Varmland, Sweden
From a recent discovery, we have several cross-section slices of microporbe-verified material in which the filipstadite occurs as black submicroscopic overgrowths intimately associated with jacobsite, hausmannite and possibly other species. Formerly known from only a single specimen @ Langban, slices from 1.5 to 7cm across @ 45.00, 75.00, 100.00 and 150.00 each.

FLUORAPATITE- Imilchil, Er Rachidia Province, Morocco

GOLD: SPECIAL OFFERING
We have a number of outstanding native gold specimens from three different localities in Brazil. The explosion of recent gold mining operations there has brought many fine specimens to market, and specimens commanding up to $500 a gram (!!) were seen in Tucson this year. Our prices are considerably lower, still not inexpensive, but all are quite solid, moderately crystallized and very impressive. Pictures of a few of our available specimens are available; all are first-come, first served, FOB our warehouse.

HEDENBERGITE- South Mountain, Oywhee Co., Idaho
Rich, dark brownish radiating aggregates and bundled masses of hedenbergite crystals comprising matrix, occasionally with minor magnetite. Described from this area in the late 1920's, these samples were collected circa 1960 and were recently uncovered once again in our warehouse! Specimen sizes range from 3cm to 8cm across @ 8.50, 15.00, 25.00 and 40.00 each. A few monster-sized museum samples from 12cm to 20cm(!!!) or more, from 75.00 to 200.00 each!

KAERSUTITE- near Hoover Dam, Mojave Co., Arizona
One of the few titanium bearing amphibole minerals, kaersutite occurs as greenish black glassy crystals frozen in camptonite rock matrix, with occasional prism faces evident. Reasonably priced specimens with moderate coverage, 3cm to nearly 8cm @ 15.00, 20.00, 30.00 and 45.00 each.

LARNITE in SPURRITE- Camphouse, Ardnamurchan, Scotland
From across the Irish sea from the type locality, larnite occurs here as grey intergrowths in lighter grey massive spurrite. Not much too look at, but most specimen have at least one saw-cut face to reveal the minerals present. Representative for the locality, sizes from 0.5cm to 4cm @ 20.00, 35.00, 50.00, and 75.00 each.

METATHENARDITE (IMA 2015-102)- Glavnaya Tenoritovaya, Tolbachik, Km Russia
Another NEW SPECIES from this famous volcano, here as very tiny greyish grains <1mm mounted on 1cm stubs. Formula: Na2SO4, hexagonal, IMA #2015-102. The mineral is named for its dimorphous relationship with thenardite, and also giving credit to Lacroix who named this then- hypothetical, presumably hexagonal mineral in 1905. We have only a few samples of this rarity on hand @ 95.00 each. List alternates!

MOHNITE (IMA #2014-101)- Punta de Lobos, Iquiqui, Tarapaca, Chile
This NEW SPECIES was found here in 2010, prior to its eventual discovery and description from the nearby type locality at Pabellon de Pica. These are nearly pure, pale tan-brown monomineralic aggregates of the species, formula: (NH4)K2Na(SO4)2, trigonal, IMA #2104-101. The mineral is the ammonium analog of
aphthitalite. A small supply available in very rich specimens, sizes from about 2cm to 4cm across @ just 45.00 and 85.00 each, depending on size.

NATROLALUNITE- Sugarloaf Butte, La Paz Co., Arizona
From one of the only reported Arizona localities, we have a few specimens of relatively pure, dense natroalunite comprising matrix. These are a typical dull white color and quite solid, sizes from about 2cm up to 5cm across @ 15.00, 25.00 and 45.00 each.

PARAMONTROSEITE- Paradox Valley, Montrose Co., Colorado
A rather ugly mineral, paramontroseite occurs as dull, black coatings and masses, typically forming the altered surfaces of montroseite-rich specimens. The type locality is within the Paradox Valley, but we do not know if these samples came from the precise prospect that yielded the type material in 1955. Rich specimens recently uncovered in our warehouse, sizes from about 2.5cm to 6cm across @ just 15.00, 25.00, and 45.00 each.

QUARTZ- Flowery Lode, Constock, Storey Co., Nevada
From the famous gold-producing Constock District, we've uncovered a small lot of transparent quartz crystal groups on matrix, with individual crystals ranging from druses to 2cm tall richly scattered on massive quartz. Some of the larger specimens show a second generation of tiny spine-like crystals emerging from the bases of larger crystals, while others show small veinlets and mases of unidentified grey metallic sulfides. Specimens from about 2.5cm to 7cm across @ just 5.00, 10.00, 20.00 and 30.00 each.

RHODOCHROSITE- Foote Mine, Kings Mtn, Cleveland Co. North Carolina
From an old stash of material, we have a few smll samples of pale pink rhodochrosite from this prolific locality, here as minute rhombs and slightly elongated and rounded aggregates over quartz matrix. An interesting locality for the species, all with modest micro potential as well, sizes average 1cm to perhaps 1.5cm priced according to quality @ just 7.50 and 10.00 each.

SCHAFARZIKITE- Buce della Vena Mine, Tuscany, Italy
Another in a series of iron antimony minerals from this locality, schafarzikite occurs as black masses scattered on and in a limestone matrix, likely associated with and nearly indistinguishable from versiliaite and apuanite, save for the slightly more intense black color. Available as 2cm or 6cm pieces @ 30.00 and 65.00 each.

SCHEELITE- Crater Island Dist., Box Elder Co., Utah
Last year, we offered powellite specimens from this locality, their identity based largely on the typical yellow fluorescence observed. However, we have recently completed analytical work on several of these samples, and the majority are, in fact, chemically tungsten-dominant and therefore scheelite, not powellite! Hence, change those lables! Anyone interested in the samples, we still have a few left, as described here: We have a large lot of nicely fluorescent (yellowish, best in SW, less in MW and LW UV) scheelite from the northern end of the Taylor Occurrence, here as small but richly scattered spotty aggregates typical of the "stary night" appearance of the mineral. The mineral is in a skarn that sometimes shows superficial chalcedony (FL SW green), and there is minor calcite evident as well. These range in size from modest 5cm specimens to very heavy 15+cm monsters @ just 10.00, 25.00, 50.00, 75.00 and 100.00 each, depending on size and coverage.

SERANDITE on CATAPLEITE pseudo- Mont St. Hilaire, Quebec, Canada
Delicate, salmon-pink triclinic crystals of serandite nicely scattered over strange, dodecahedral-appearing reticulated catapleite pseudomorphs after a eudialyte mineral. These small but attractive specimens are mounted on leucite bases and may disclose other MSH-associated minerals as well, the underlying euhedral crystals resembling Goldschmidt's illustrations (#s 11 and 13) for eudialyte. Choice specimens, overal 1cm to 5cm @ 35.00, 50.00, 65.00, 75.00, 85.00 and 125.00 each, depending on quality. Attractive and curious material!

THORIANITE- Balangoda, Ratnapura District, Sri Lanka
We recently uncovered a small lot of thorianite, here as small crude crystals and rounded aggregates without matrix, ex-A.E. Foote and collected in 1905. From the type locality for the species (!), we have a few small samples from 2mm to nearly 5mm across @ 10.00, 15.00, 25.00 and 35.00 each, depending on overall size.

TINNUNCULITE (IMA 2015-021a)- Mt. Rasvumchorr, Khibiny, Kola, Russia

This organic mineral's formula is: C5H4N4O3*2H2O - monoclinic, IMA # 2015-021a. This is the first natural occurrence of a previously discovered, semi-anthropogenic material found in the excrement of the kestrel bird (Falco tinnunculite) that was altered by the hot gases of the burning coal dumps at Kopeisk in the southern Urals. Single mounted grains @ 80.00 each. Only a few available!

TOPAZ with QUARTZ- Schneckenstein, Kielberg, Saxony, Germany
This old and well known locality is famous for its topaz specimens, perched on a cliff in a quartz greisen, now closed to collecting. This old piece is ex-Czech National Museum and comes with their label, showing a somewhat tabular, small clear topaz about 7mm perched at one edge of a crystallized, quartz-filled vug, with smaller, lesser topaz evident as well. Not an extravagent specimen, but from a classic locality with the Museum label, size about 5x5 cm @ 85.00.

TURQUOISE- Shiyan Prefecture, Hubei Province, PR China
From a small find last year, these are bright blue, nodular masses of turquoise comprising matrix. All show moderately good color in these cauliflower-like masses that average just over 2cm across @ a very modest 30.00 each. Only a few available; please list alternates!

UVITE - Brumado Mine, Bahia, Brazil
Frosted pale green to glassy, deep green single crystals of uvite tourmaline without matrix. Most of these are somewhat flattened, hexagonal-outlined crystals without matrix. Neat specimens, sizes from 0.8 to 1.5cm @ just 10.00 and 15.00 each, originally obtained years ago from Dick Gaines and likely the (OH) dominant endmember of the series.

VASILSEVERGINITE (IMA 2015-083)- Arsenatnaya fumerole, Tolbachik, Kam Russi
This NEW SPECIES occurs as aggregates of bright green, tiny crystals on a friable, altered basaltic breccia. Formula: Cu9O4(AsO4)2(SO4)2 - monoclinic, IMA # 2105-083.

Author's type locality material, of course, from the second scoria cone of this prolific Kamchatka volcano, specimens about 1mm across in a protective capsule @ 125.00 each. Only a few on hand; list alternates!

VIVIANITE pseudo var: MULLICITE- Mullica Hill, Gloucester Co., New Jersey
This well-known occurrence shows elongated, finger-like structures comprised of conglomerated, brownish-red, pebble-rich masses wrapped around and covering rod-like structuers of fossil belemnites that have been completely replaced by dark, greenish-black radiating vivianite, appearing as cores within the finger structures, occasionally with hollow centers. Interesting pseudomorphs from an old locality, specimens average about 4cm
tall @ just 15.00 each, a few slightly larger @ 20.00.

WHITMOREITE etc.- Palermo Mine, North Groton, New Hampshire
Small micro crystals of golden yellow to brown, transparent radiaitng clusters of whitmoreite sparsely scattered on matrix, typically with siderite and a variety of phosphates, potentially including strunzite, laueite, jahnsite, messelite etc. From a recently acquired micromount collection, all of these are suitable for viewing under the 'scope and are already mounted in a standard micromount box. Matrix sizes average about 1.5cm @ just 12.50 each, with a few slightly larger specimens @ 25.00 and 40.00 each.

YODERITE in TALC- Mautia Hill, Kongwa, Dodoma Region, Tanganyika
Dark bluish black prismatic aggregates of yoderite richly scattered in a pinkish, schistose matrix with minor admixed talc and quartz. When first described, the locality was considered lying within the Central Province of Tanganika, now Tanzania. A moderately rare species, with a copy of an H. Yoder-signed label, sizes range from 1.5cm to 6cm across @ 15.00, 25.00, 45.00, 60.00 and 85.00 each. Type locality, of course!

CATALOG 21602 – Volume XLIII, No. 2

Our latest list has a number of new species, as well as our usual assortment of rarities, old classics and interesting
locality pieces. As always, specimens are available on a first-come, first-served basis, FOB our warehouse.

ALFREDOPETROVITE (IMA 2015-026)- El Dragon Mine, Potosi Dept., Bolivia
This NEW SPECIES occurs as minute, greyish white balls and aggregates lightly scattered on matrix, typically with light blue chalcomenite and occasionally white felsobanyaite. Underlying metallic matrix is subordinate, consisting of massive krutaite and possibly other selenides. Formula: Al2(Se4+O3)3*6H2O - hexagonal, IAM #2015-026. Type locality, of course, appropriately named for our good friend and former Excalibur assistant, Alfredo Petrov. Specimens average about 1cm across @ just 55.00 each.

ASPHALTUM with COFFINITE- Dysart #1 Mine, Ambrosia Lake, New Mexico
This McKinley Co., location (aka Rio de Oro Mine) was extensively studied by H.C. Granger in the early 1960s, dividing the mineralogy of this deposit into two distinct categories, these samples apparently from the prefault zones of the deposit. The matrix is a loosely packed sandstone (Westwater Canyon Member within the Morrison Formation) and hosts minute, black hydrocarbon chelate masses (asphaltum) containing extremely fine grained coffinite, with many other reported vanadates and secondary uranium minerals occurring primarily in the post-fault zone of the deposit. These are really ugly specimens, some with minor white kaolinite, mildly radioactive, but interesting nonetheless. Samples range from about 5cm to 9cm across, at just 15.00, 25.00 and 45.00 each.

AZURITE with MALACHITE- Sepon Mine, Savannakhet Province, Laos
From a highly unusual locality, these are fairly attractive specimens comprised of deep blue azurite in brilliant, tiny crystals and druses richly lining fully exposed seams and surfaces, virtually all with deep green, somewhat fibrous malachite as well. Colorful specimens and a classic association from a rarely-available country, sizes range from about 4cm to 5.5cm @ just 45.00 and 55.00 each. Only a few on hand!

BERMANITE etc.- White Elephant Mine, Custer Co., South Dakota
Dark reddish brown druses of bermanite nicely filling vugs in phosphate-rich matrix, most associated with minor robertsite, leucophosphite and possibly other species. From an old stash of one of Bill Roberts' former grad students, most have modest micro potential and range from 2cm to 3+cm across @ 20.00 and 35.00 each. Nice!

CALAVERITE- Cresson Mine, Cripple Creek, Colorado
Bright, silvery white metallic aggregates of this interesting gold telluride very sparsely scattered in rock matrix, some with micro purple fluorite, pyrite and/or needle quartz, potentially with other tellurides. Classic locality material but not high grade stuff, matrix sizes from 2cm to 5cm @ 15.00, 35.00 and 55.00 each.

DACHIARDITE-Ca- nr. Zvezdel, Momchilgrad District, Bulgaria
This small locality has produced several interesting species in the past, and these dachiardite-Ca samples occur as colorless to white radiating clusters embedded in crude andesitic matrix, occasionally with minor agate and/or lamellar clinoptilolite-Ca. Recent studies have found several other zeolites new for the locality (see elsewhere in this list), and these are microprobe-confirmed samples, only a few on hand, averaging 2.5cm across @ 60.00 each.

DACHIARDITE-Na- nr. Zvezdel, Momchilgrad District, Bulgaria
A new mineral for this off-beat locality, the first reported occurrence for the Na-dominant diachiardite in Bulgaria, these from microprobe-confirmed material. The mineral appears as small, colorless to slightly yellowish radiating hemispherical sprays of flattened crystals embedded in agate, occasionally with clinoptilolite-Ca. Specimens average a little over 2cm across @ 95.00 each. Only a few on hand!

EUXENITE-(Y)- Sahamandrevo, Antananarivo Province Madagascar
A squat, euhedral crytsal of euxenite-(Y) without matrix, showing typical, tan surface coating over dark brown, glassy REE core. The crystal is accompanied by an original Tuthill label, an active mineral dealer circa 1929 to perhaps 1956. The crystal is about 3.5cm wide and 2cm tall from a neat locality, offered at just 85.00 with Tuthill's original label.

FAIRFIELDITE- Cigana Mine, Galileia, M.G., Brazil
Excellent stacked plates and rosettes of greyish, glassy micro fairfieldite crystals and groups scattered on matrix, typically associated with white albite, quartz and/or muscovite. Fine micro potential, overall sizes from 2cm to 3cm across @ 20.00, 30.00, and 40.00 each. One 4x3.5cm specimen @ 55.00. Super!

FERRIERITE-K- nr. Zvezdel, Momchilgrad District, Bulgaria
A new locality for this rare zeolite, the first find in the world outside of either California or Japan! Microprobed samples showing tiny, slightly yellowish rosettes comprised of radiating, flattened crystal aggregates to a few millimeters, occasionally with somewhat flattened clinoptilolite-Ca at the boundaries of greyish agate and andesitic tuff. Only a few specimen available from this zeolite-rich locality, and the first reported occurrence of the species here, sizes average about 2cm across @ 75.00 each. List alternates!

FIZELYITE- nr Velardena Shaft, Santa Eulalia, Mexico
This uncommon mineral occurs here as tiny, dull greyish black masses intergrown with plagionite in blackish brown limonitic matrix. These were from the 1987 find in the West Camp area of Santa Eulalia, ex-Megaw and Cureton material. Ugly stuff but from an unusual occurrence, specimens from 2cm to nearly 6cm @ 15.00, 25.00 and 40.00.

FLUOBORITE- New Method Mine, San Bernadino Co., California
This uncommon mineral occurs here as rich, pale creamy masses largely comprising matrix, typically as lightly fluorescent (SW UV-yellowish cream) chunks, occasionally with minor purple fluorite seams that show a pale greenish fluorescence as well due to minute UO2-mineral inclusions. From an old and prolific locality, specimens from about 2.5cm to 10cm across @ 8.50, 12.50, 20.00, 35.00 and 45.00 each.

GAZEEVITE- Jabel Harmun, Judea Mts., Palestine
This NEW SPECIES occurs as minute, white grains in larnite/brownmillerite-rich matrix, often with a wide range of rare associations that are all identified in teh accompanying SEM images for each sample. Formula: BaCa6(SiO4)2(SO4)2O, trigonal, IMA #2015-037. Two samples, about 1cm+ in epoxy mounts, elegantly
documented with two color photos, two SEM images, and microprobe data for each, HOLOTYPE samples @ 325.00 each. See next listing!

GAZEEVITE- Negev Desert, W Slope of Har Parsa, Israel
Confirmed at this CO-TYPE locality by the same authors who described it from Palestine, the mineral occurs here in a similar assemblage to the type locality, and it is similarly well-documented with a pair of color images and two SEM images as well, also with a range of specified associations. Formula: BaCa6(SiO4)2(SO4)2O - trigonal, IMA # 2015-037. Each 1cm sample is epoxy mounted and offered at just 295.00 each.

GERMANITE- Inexco No. 1 Mine, Jamestown Dist., Colorado
Massive ore specimens, ex-Gene Foord (foordite) Collection and accompanied by copy of his label. The pieces are dense, dark metallic showing typical iridescent colors of purple-golden-blue over most of the surface. A few to 2cm with a photocopy of Gene's label @ 75.00 each.

HILLESHEIMITE (IMA 2011-080)- Graulay, Hillesheim, Eifel, Germany
A very rare mineral from its type locality, originally described in 2011 but virtually none made its way to the market. The mineral occurs as micro, pale yellowish lamellae, often with yellow sprays of columnar, altered gotzenite and other species in cavities of alkaline basalt. Author's studied (and probed) material, only three available, averaging 2cm across @ 195.00 each, with pinpointing arrows.

JAROSITE w/ SULFUR, CINNABAR- Steamboat Springs, Washoe Co., Nevada
An unusual occurrence of small, pale orange-brown micro crystals of jarosite lightly scattered on white silaceous sinter matrix, typically with bright yellow native sulfur, pale red druses of cinnabar and occasionally micro pyrite as well. Interesting association specimens with modest micro potential, TNs @ 8.50 each. One large hand specimen about 8x7cm @ 55.00.

KALIOPHILITE- Pollena Q., Mt.Somma, Vesuvius, Italy
Nice looking material, kaliophilite occurs as opaque tan to white acicular to prismatic aggregates and microcrystals scattered in vugs in rock, some associated with glassy meionite crystals. Too large for micromounts as is but can be trimmed, these are uncommon, type locality specimens from 3cm to nearly 8cm across @ 25.00, 35.00, 50.00 and 65.00 each.

KTENASITE- 79 Mine, nr, Hayden, Gila Co., Arizona
Excellent, bluish green masses and crusts of this uncommon species richly scattered on matrix. From the mid-1970's find on the 31 stope at this prolific locality, we have an old lot of specimens, generous sizes from 4cm to nearly 7cm @ just 15.00, 30.00 and 45.00 each.

LEMMLINITE-K w/ VINOGRADOVITE- Koashva Open Pit, Khibiny, Kola, Russia
Little material has appeared sisnce our original offering from this rare mineral in 1998, here from the type locality. A small but interesting new discovery shows tiny orange to orange-yellow crystals of this typically colorless phase, all in excellent euhedral micros, associated with natrolite and nicely fluorescent fibrous vinogradovite and potentially other rare minerals. Colorful for the species, fine micro potential with excellent associations, specimens average about 2.5cm @ 125.00 each. Only a few available, all quite fine!

LEPIDOLITE- Aracuai, Minas Gerais, Brazil
Well crystallized, relatively large plates of "lepidolite" mica, all showing pleasing lavender color typical of the mineral. Although now mineralogically considered an undifferentiated member within the polylithionite-trilithionite series, the lepidolite name is forever locked in the minds of collectors and petrologists, regardless of its official status mineralogically. Typically in small, scaly groups, we have a few very thin but otherwise solid plates of modest size, averaging 3cm to 4cm across @ 10.00 each, with bulk lots at $0.65 per gram (50g minimum), or as extraordinary, thick, solid plates to 9cm across and weighing 340g to 370g each @ 200.00 each! Only a few available!

LOBANOVITE (IMA 2015-15B)- Kirovski Mine, Khibiny, Kola, Russia
This newly named and approved species is the result of a detailed study of the formerly invalid "magnesiumastrophyllite" from this Mt. Kukisvumchorr locality, now designated as the type locality for the species. It occurs as excellent bronze-colored lamellae in pegmatitic matrix, typically with richly fibrous, green aegirine, potassic feldspar and/or minor sphalerite. Rich samples averaging about 3cm across @ just 45.00 each!

LOELLINGITE- Callington, Cornwall, England
Grey metallic crystalline masses of this iron arsenide occur in a quartz matrix. Representative material for loellingite from a great locality, the last of the material; we have stocked for many years, sizes from 2.5cm to nearly 6cm @ 15.00, 25.00 and 45.00 each.

LUETHEITE- Patagonia, Santa Cruz Co., Arizona
Pale green to blue-green, vitreous masses and aggregates of this unusual mineral sparsely scattered in/on rhyolite matrix, occasionally with minor chenevixite. Type locality material from the original find, matrix sizes from 2cm to 6cm @ 20.00, 40.00 and 55.00 each.

MANGANONEPTUNITE on pseudomorph- Mont St. Hilaire, Quebec, Canada
Deep red, glassy micro crystals and aggregates of manganoneptunite isolated on the faces of weird, euhedral catapleiite pseudomorphs after a eudialyte ggroup mineral, occasionally associated with other species as well. These are excellent for micros and small TNs, quite attractive, and most mounted on transparent leucite bases. The underlying reticulated pseudomorphs are unique and interesting as well, resembling Goldschmidt's illustrations #11 and 13 for eudialyte. Specimens range from about 1cm to 1.5cm tall and are priced based on coverage and associations, priced at 35.00, 50.00, 85.00 and 125.00 each. Very fine!

MESSELITE etc.- White Elephant Mine, Custer Co., South Dakota

MIXITE variety CALCIAN MIXITE- Gold Hill Mine, Tooele Co., Utah
Minute radiating balls of pale green calcian-rich mixite scattered over quartz-rich matrix, occasionally with cornwallite, conichalcite or admixed chrysocolla in seams in matrix. An odd variety of teh species with excellent micro potential. Several on hand, 2.5cm to nearly 7cm across @ 17.50, 35.00 and 55.00 each.

NAMBULITE- Gozaisho Mi, Iwaki, Fukushima Pref. Japan
This unusual species occurs as dull orange-brown masses sparsely scattered in dense, blackish brown manganese ore matrix, occasionally with other admixed species. Excellent locality material, sizes from about 1.5cm to 3cm @ 20.00, 45.00, and 65.00 each.

PENFIELDITE with BOLEITE- Casucha Mine, Sierra Gorda, Chile
Micro elongated crystals and masses of greyish white penfieldite scattered in vugs in matrix, most associated with dark blue boleite aggregates and possibly other minerals, most typically on corroded cores of galena in rock. Good micro potential on these as well, specimens from about 2.5cm to 8cm across @ 15.00, 25.00, 45.00, 75.00 and 100.00 each. Excellent!

PLUMBOGUMMITE pseudo @ PYROMORPHITE- Yangshuo Mine, Guilin Prov, Guangxi, PR China
Very fine, pale greenish-blue plumbogummite replacing hexagonal, hoppered single crystals of pyromorphite, these without discernable matrix and most standing about 2.5cm tall. There has been much discussion about the locality of this latest find, and some have been labeled as Daoping, also in Guilin Province, but the vast majority of experts suggest the Yangshuo Mine is correct. An interesting replacement pseudomorph retaining the pyromorphite habit,
actually moderately attractive, only a few specimens available @ 60.00 each.

PSEUDOMALACHITE- Chambishi, Copperbelt Province, Zambia
An old specimen, with A.E. Seaman Mineral Museum label identifying this previously unreported species at the locality with the predecessor "Northern Rhodesia" name, placing the origin of the sample sometime between 1911 when the country was formed and 1964 when it became Zambia. The sample shows massive quartz and a vein of sedimentary rock with numerous seams and exposed pockets of deep blue-green pseudomalachite apparently overlaying chrysocolla as well. Moderately colorful and an interesting locality with good provenance, specimen is about 6x5cm @ 55.00. One only!

QUARTZ (Faden Habit)- Tole, Wana, South Waziristan, Pakistan
Excellent, elongated tabular groups of water-clear quartz forming classic faden crystals with multiple and complex terminations throughout, all radiating from a central "spine". These show disjointed growth, typical of the faden pattern. Fine specimens, very attractive, handsome samples from about 6cm to 8cm tall @ just 45.00 and 55.00 each.

RHODOCHROSITE with PYRITE- Oppu Mine, Naka-Tsuharu-gun, Aomori, Japan
A small lot of excellent material from this classic locality was recently uncovered here, these as pale pink botryoids of rhodochrosite comprising matrix, all nicely sprinkled with complex and somewhat rounded, small pyritohedral crystals of brilliant pyrite. Relatively flat specimens range in size from about 5cm to 7.5cm @ 45.00, 75.00 and 100.00 each.

SIDERITE- Allevard, Isere, Rhone-Alpes, France
An old and rather attractive specimen for the mineral, here as tan to pale brown rhombs to 1.3cm richly scattered and intergrown, comprising a dense and heavy matrix with small, water-clear quartz crystals sparsely scattered about. A old A.E. Seaman Museum specimen from a great European locality, overall size about 10x6 cm @ 75.00, with their old cardboard display label.

STAROVAITE with LAMMERITE- Yadovitaya Fumerole, Tolbachik, Kam. Russia
From a new find at the type loclaity for the species, starovaite occurs here as extremely tiny, somewhat prismatic pale yellowish green to brownish crystals in aggregates sparsely scattered on scoria matrix, often associated with darker green, glassy lammerite as well. From the second scoria cone of the northern breach of the main fracture of this well-studied Kamchatka volcano, this is a rare K-Cu-O vanadate, from the only known locality in the world for the species. Matrix specimens about 4cm across @ 175.00 each; only five available!

STIBNITE- Hillgrove, Sandon Co., NSW, Australia
Recently uncovered in our warehouse, a small lot of slightly twisted and bent, elongated crystals and aggregates of silvery metallic stibnite, these primarily without matrix and showing rich, convoluted habit typical of the area. Primarily an old gold mining district, the region was discovered circa 1887 and was know for antimony and minor tungsten production as well. Only a few, moderately attractive specimens on hand, sizes from about 3cm to 5cm long at just 30.00 and 55.00 each. Nice!

STRASHIMIRITE etc.- Jackrabbit Mine, Lyon Co., Nevada
As featured in thd May, 2015 issue of Mineral News, strashimirite occurs here as pale greenish, somewhat fuzzy aggregates scattered on matrix, occasionally with minor brochantite, aurichalcite or other species. We have a very few specimens from this relatively obscure locality, specimens from about 2cm to 4cm across @ just 10.00, 15.00 and 25.00 each.

TOSUDITE in KAOLINITE- Takatama Mine, Fukushima Pref., Japan
Masses of the clay mineral tosudite are available once again! This is dusty, ochre-colored material admixed with kaolinite from the type locality for this species, not much to look at but from the classic location. Capsules filled with small fragments @ 15.00 each; small matrix specimens from 1cm to 2cm @ 25.00 and 40.00 each.

TRILITHIONITE- Dobra Voda Pegmatite, Moravia, Czech Republic
Rich pink platy crystalline masses of trilithionite in a pegmatite matrix. Moderately attractive material, occasionally associated with crude, tiny pink tourmaline in some samples. Some of the nicest lithium-rich mica we've seen from eastern Europe. In sizes from 2.5cm to 6cm, a bargain at just 8.00, 15.00, and 25.00 each.

URANOPYROCHLORE- MacDonald Mi, Hastings Co., Ontario, Canada
Dark brown, vitreous to greasy patches of a mildly radioactive pyrochlore group mineral are richly scattered in feldspar, occasionally with orange-hued calcite as well, with potential for zircon and several other radioactive phases, too. We struggled with a proper name for this material, going back to analyses published as early as 1961, later in 1977 and still later from similarly named minerals! The IMA nomenclature changes of 2010 discredited
"uranpyrochlore" suggested "uranopyrochlore" as a name but not a species, and hinted that the material might be oxycalciopyrochlore (already seen elsewhere as hydroxycalciopyrochlore -maybe) or others. Without a detailed structural analysis, all is guesswork, it seems. So we are listing these rich samples as "uranopyrochlore" as the 2010 Atencio paper suggested, even though the name is not an accepted species! Confused? In any case, we have several decent samples, sizes from about 2.5cm to 6cm across @ just 15.00, 30.00 and 45.00 each. There is a hot 9cm Univ of Delaware sample @ 150.00, and also a monster 17x12cm boat anchor purchased back in 1961 @ 225.00. Take your pick!

VANADINITE- Touissit, Oujda, Morocco
Warm grey-green vanadinite crystals project from all sides of the matrix. These are resinous, hexagonal barrels, some are zoned and display white tips. Reasonably attractive, old material from more than 20 years ago, sizes from 3cm to 5cm @ 15.00, 25.00, 35.00.

COLLECTIONS

Positively identified from only a few localities, this occurrence is quite rich, with matrix specimens having one side completely covered by asbolan. Offered as a few admixed grains in a capsule @ 12.50, or as a matrix piece in sandstone, 1cm to 2cm @ 25.00 and 45.00 each.

BERTHIERITE- Pribram, Bohemia, Czech Republic
A large and old specimen, comprised of densely aggregated grayish masses completely comprising matrix. An old A.E. Foote label (#119) is attached to the back of the piece, and it is also accompanied by a Dr. P.A. Foster (1889-1968) personal label suggesting a 1943 acquisition from Wards. The piece is rich and from a classic locality, overall size about 8x6cm at just 85.00, with old labels.

BERYL- South Alstead, Cheshire Co., New Hampshire
From one of the many beryl-rich areas of New Hampshire, these crude beryls were collected by E.W. Heinrich and recently uncovered in our warehouse. Colors range from yellowish to pale blue and all are essentially opaque, the better samples showing some crystal faces but otherwise massive in habit. Old stuff,
good reference samples from about 2.5cm to 6cm, priced according to quality @ 7.50, 15.00 and 30.00 each.

CALCITE- Red Dome Mine, Chillagoe, Queensland Australia
A superb, gemmy calcite crystal, near floater in its complex terminations and lack of matrix, showing many convoluted faces, twin lines and high luster rarely seen in other calcite localities! We have had two of these in the last 15 years, and this one is a very fine and complex crystal about 4.5cm tall @ just 75.00. A gem!

CARLETONITE- Mont St Hilaire, Quebec, Canada
While we have many small samples of this attractive blue mineral, we recently acquired a pair of surprisingly large (for the species) specimens from this prolific locality. Each sample stands about 4cm tall (!!!) and is comprised of attractive, well-crystallized carletonite crystals and aggregates nicely intergrown, some with vitreous faces reaching more than 2cm across! Highly unusual, from the 2001 find and originally priced by our source at 850.00, we offer these extraordinary examples at a discounted price of just 600.00 each. Don't miss these!

CHLORMAYENITE & MAGNESIOFERRITE- Kopeisk, Chlyabinsk, S. Urals, Russia
This uncommon mineral was originally approved in 2010 as the mineral brearleyite. In a long list of redefinitions and discreditations in 2013, it became the mineral chlormayenite and was confirmed from six different countries. This occurrence is bright yellowish white, granular aggregates richly covering the
surface of black, micro crystallized magnesioferrite matrix. An interesting association, specimens average just over 1.5cm @ 95.00 each, well below similar material from elsewhere!

DIOPTASE with PLANCHEITE- Reneville, Kindanba District, Congo
An old specimen obtained many years ago from Dr. Paul Sainfeld (sainfeldite) in an exchnage with the Ecole Superieure des Mines in Paris, the original label (supplied) in Sainfeld's own hand suggests this is "bisbeeite with dioptase", but modern studies have shown it to be pale blue plancheite. The associated
dioptase has excellent, deep green color and glassy luster but is not well crystallized, instead acting as a a fine accent color for the richly scattered blue plancheite that covers most of the specimen. A one-of-a-kind older piece with excellent provenance with its somewhat tattered but historic label, size about 8x5cm @ 250.00. Attractive!

EMMONSITE- Moctezuma Mine, Sonora, Mexico
Thin botryoidal encrustations and smears of bright green emmonsite sparsely scattered on quartz breccia matrix of these samples. A moderately uncommon species from a prolific locality for tellurium-rich phases. Overall sizes about from 2cm to 4.5cm @ 30.00, 45.00 and 60.00 each.

COLLECTION
San Rafael Mine, Nye Co., Nevada
We have many specimens on hand from our research work on this locality that resulted in the publication of the Rocks and Minerals article in 2010 that we happily co-authored. While the stock lasts, we offer a lot of ten (10) specimens from the locality, with sizes ranging from 2.5cm to 4cm across, most with good micro crystals from a wide range of species. The locality has produced nearly 70 different minerals, and we are certain you will find some interesting species such as wulfenite, mimetite, segnitite, adamite and others. You can expect some duplication in each lot of ten (10) specimens, but you can't beat our price of just 75.00 per lot, and we'll even throw in a signed color copy of our article at no extra charge!

EQUIPMENT
LOUPES: 10x and 20x (with LED)
We once sold good Russian loupes for many years, watching the prices rise from as little as $8.00 up to $26.00 in our last shipment. Although a good product, the prices rose far outside what we felt was reasonable, and we have stocked two alternative loupes for collectors for the last five years with pleasing results and stable pricing:
10x Magnification Loupe with 21 mm field of view, polished metal housing with double lens, screw
assembly and hanging loop, with see-through plastic box case @ just 10.00 each. Great for the price!
20x Magnification Loupe with 18 mm with built in high intensity LED light (battery included!). The strong
light source (with on/off switch) solves the lighting issues present with most higher magnification loupes, and
these also have a full metal housing, screw assembly, hanging loop plus battery removal tool and seethrough plastic box case @ just $20.00 each. A super deal, and a very useful field and laboratory tool that makes a great gift, too!

GEMS
CHRYSOPRASE- Brazil
This variety of chalcedony is gem-quality, emerald-green in color and superbly eye-clean, the color due to minute amounts of nickel silicate inclusions. Uncommonly clean stones, offered here as 6x4mm calibrated cabochons at just 7.50 for a matched pair, or 15.00 per lot of 5 stones. Don't miss these!
FACET ROUGH ASSORTMENT- Various Localities Worldwide
Among the gem and mineral mining areas of the world, it is not uncommon that glassy, clean material is isolated for its potential as faceting rough rather than as specimens, since a cut stone always brings substantially more that the mere mineral itself. We have a number of mixed lots of facet rough on hand,
most of it typically amethyst, citrine, topaz, garnet etc. in mixed varieties and assorted sizes from about 1 to 40 carats. We've lumped these into 500 carat lots, offering them at just 49.00 a lot, less than ten cents a carat!

It is a rich, densely aggregated mass of galena, devoid of single crystals but exceptionally heavy, with a small matrix exposure at one edge that shows a micro cerussite crystal in an exposed limonitic pocket. The piece is ex-Michigan College of Mines with an 1897-1927 vintage label that still uses the old "Galenite" name for the species. A good historic piece from a fairly old and obscure mine, overall about 10x6 cm @ 75.00. One only!

GEORGEITE- Carr Boyd Mine, W.A., Australia
This uncommon copper carbonate occurs as pale blue, thinly scattered masses on weathered tremolite/rock matrix, often with minor chalconatronite, malachite, or brochantite and occasionally other secondary phases. Author's material obtained more than thirty-five years ago. If your name is George, know anyone named George, or just wish to have a mineral named thusly, this is your opportunity. Specimens from about 2cm to nearly 5cm @ @ 25.00, 35.00, 50.00, 75.00 and 100.00 each, depending on coverage, not size.

GERSTLEYITE- Baker Mine, Boron, Kern Co., California
Once prolific and now quite uncommon, gerstleyite occurs as minute, deep red aggregates on a greyish-green clay, typically with elongated probertite, tincalconite and possibly other borates in association. The matrix is quite friable breaks down easily, resulting in very few larger specimens. We can offer a small but rich fragment in a capsule @ 20.00, and one 5x5cm matrix specimen @ 120.00. Type locality material, of course!

HARMOTOME- Bellsgrove, Strontian, Scotland
Small transparent to translucent twinned crystals of harmotome nicely scattered on matrix. A classic area for the species, some specimens potentially yielding some large micro's as well. Old material, matrix sizes from about 2cm to 5cm @ 8.50, 15.00, 30.00 and 45.00 each; one 9x6cm excellent sample @ 75.00.

HYDROXYLWAGNERITE- Vallone Giba, Cuneo, Piemonte, Italy
This relatively uncommon species occurs as small, somewhat creamy-beige to yellowish colored masses and aggregates sparsely scattered in a highly micaceous quartzite matrix, occasionally with tiny pyrope masses as well. Formula: Mg2(PO4)(OH)-monoclinic. Originally approved in 2004 and from here, the TYPE locality, also more properly noted as "Brossasco, Vallone Giba, Varaita Valley" in the Dora-Maira massif. Specimens from about 2.5cm to nearly 5cm @ just 30.00, 45.00 and 60.00 each.


IODARGYRITE with CERUSSITE etc- Kintore Opencut, Broken Hill, NSW, Australia
Small, somewhat brownish micro crystals and aggregates of iodargyrite sparsely scattered and surrounded by flat black botryoids of Mn-oxides, with later white, elongated cerussite micros well-scattered throughout the specimen. An interesting association piece from a well-known locality, specimen size about 5x4.5 cm @ 85.00.

KLYUCHEVSKITE- Arsenatnaya Fumerole, Tolbachik, Russia
Another rare species from this famous Kamchatka volcano, here as minute, dark green prismatic to elongated/acicular crystals reaching up to 1mm on very minor matrix. The mineral is typically associated with bright green euchlorine, and it is considerably more rare than its isostructural counterpart, alumoklyuchevskite. Only a few tiny samples on hand @ 135.00 each.

MAGNESIO-FOIITE- Tsitondronig, Fianarantsoa Prov., Madagascar
Quite remarkable, highly lustrous black magnesio-foitite tourmaline crystals without matrix, each showing excellent, sharp and convoluted faces throughout, actually dark brown when viewed under strong backlighting. These are apparent floater crystals from the 2013 find at the locality, only four excellent crystals on hand, all rather swat and averaging about 3.5cm wide at just 55.00 each. Excellent for a moderately uncommon tourmaline!

MANGANITE- Minas Gerais, Brazil
We recently uncovered four very old specimens, each ex- Michigan College of Mines and each labelled as "Minas Geraes" as the only locality information. The label types suggest the samples are circa 1897-1926 vintage, and the manganite occurs as tiny, elongated black crystals and aggregates that are highly lustrous and richly scatted in exposed seams and vugs in a somewhat botryoidal Mn-rich black matrix. Fairly heavy and dense, sizes average 6cm across @ just 35.00 each.

POWELLITE (FL)- Crater Island Dist., Box Elder Co., Utah
We have a large lot of nicely fluorescent (yellowish, best in SW, less in MW and LW UV) powellite from the northern end of the Taylor Occurrence, here as small but richly scattered spotty aggregates typical of the "stary night" appearance of the mineral. The mineral is in a skarn that sometimes shows superficial chalcedony (FL SW green), and there is minor calcite evident as well. These range in size from modest 5cm specimens to very heavy 15+cm monsters @ just 10.00, 25.00, 50.00, 75.00 and 100.00 each, depending on size and coverage.

RAUVITE with MONTROSEITE- Opera Box Mine, Montrose Co., Colorado
Highly lustrous, minute balls and tiny aggregates of black rauvite scattered in granular montroseite matrix, occasionally with other lesser secondary uranium and/or vanadium minerals evident in some specimens. A relatively uncommon mineral that begs for more study, specimens range from about 2.5cm to 5cm specimens @ 15.00, 30.00 and 55.00, with a couple to nearly 8cm @ 95.00 each. List alternates!

SERANDITE w/ EPIDIDYMITE etc- Mont St. Hilaire, Quebec, Canada
An outstanding example of the species, here as a large, orange-pink central serandite crystal about 2cm on edge, with several smaller groups on the top and side of the major crystal, also showing several white, tabular crystals of epididymite, smaller analcime, a few druses of red mangan-neptunite, all over a core of a brownish catapleiite pseudomorph after a eudialyte group mineral! A very fancy "toenail" specimen about 2.5cm x 2.5cm @ just 200.00. One only!

SODALITE- Itaju do Colonia, Bahia, Brazil
From one of the uncommon nepheline syenites in this otherwise prolific mineral producing area, we have a few deep blue, massive sodalite specimens comprising matrix, some with minor white spiderwebs of calcite and potentially other species. Probably cutable, but not our thing, specimens average about 4cm across at just 5.00 each from this neat locality.

SOGDIANITE pseudo @ ZEKTZERITE- Washington Pass, Okanogan Co., Washington
Pale pink crystalline aggregates of brightly fluorescent sogdianite scattered in microcline/arfvedsonite matrix, these as apparent pseudomorphs after zektzerite. An uncommon mineral from an excellent locality for the species, overall sizes from about 2cm to nearly 5cm across @ 45.00, 65.00, 90.00 and 125.00 each.

STISTAITE- Ekiaidai Stream, Syrdar'ya, Uzbekistan
A minute, single black grain about 400um across of this extremely rare species offered in a 1.5cm probe mount, accompanied by an SEM image and X-ray spectra plus full quantitative chemistry. The data sheet was signed by Dr. N, Rudashevsky (rudashevskyite) over 30 years ago, noted as type locality with a general locality designation of "NW Kyrgystan" when Russian scientists were still required to obscure strategic mineral localities, subsequently
relvealed several years later by Pekov to be at the cross-border locality in Uzbekistan. From the type locality for this tin-antimony mineral, well documented by a fmaous mineralogist, only one available at 185.00.

TATARINOVITE (IMA #2015-055)- Bazhenovskoe Deposit, Asbest, Ural, Russia
This NEW SPECIES was discovered in the Southern Open Pit of this large chrysotile deposit, here as small but fairly rich, sugary granular aggregates and imperfect crystals, typically with minor orange-pink grossular and/or greyish diopside. Formula: Ca3Al(SO4)[B(OH)4](OH)6*12H2O - hexagonal, IMA # 2015-055. A new member of the ettringite group, specimens from about 1cm to 1.5cm @ 165.00 and 195.00 each, depending on size/coverage. Only a few available, type locality material, of course!

TRONA- Tronox Mine, Sweetwater Co., Wyoming
Large, relatively clean masses of solid trona comprising matrix, these from the #17 Bed, No. 8 Shaft of the FMC/Tronox Mine, with several showing columnar, oriented aggregates as well. The material shows zoned yellow fluorescence under both LW and SW UV, and specimens range in size from about 4cm to 12 across @ 15.00, 40.00 and 65.00 each. Rich!

VALLERIITE- Pima Mine, Pima Co., Arizona
Dark bronzy masses of this odd sulfide-hydroxide mineral are fairly well distributed as thin exsolution plates and films in these specimens. Valleriite, iron sulfide magnesium hydroxide, occurs here as platy masses intermixed with magnetite in rock, likely of hydrothermal origin. Good representation for this unusual mineral, although not very photogenic, sizes from 2cm to nearly 5cm at just 15.00, 30.00, and 45.00 each.

WAVELLITE- Mauldin Mtn., Montgomery Co., Arkansas
Pale green drusy wavellite richly scattered over dark grayish rock matrix, these collected in the mid-1970s or earlier and just recently uncovered in our warehouse. Some of the mid-sized specimens show globular concentric bands, while others are rich carpets of microcrystalline wavellite. Specimens range from about 2.5cm to nearly 8cm across @ just 5.00, 10.00, 20.00 and 35.00 each. Moderately colorful due to contrasting matrix!

WILLEMITE (Slickenside)- Sterling Hill, Ogdensburg, Sussex Co New Jersey
Slickensided ore specimens of red-brown willemite show typical, pearly luster across the large slickensided faces, but these samples also show thin, straight-line streamers of brightly fluorescent willemite, the morphology under SW UV suggesting the otherwise granular willemite was literally dragged across the sample as a result of friction during its movement along the fault. Interesting stuff, specimens from about 8cm to 11cm across @ just 55.00 each.

BOOK
The Microscope- by Jabez Hodd (1883)
A hardcover copy of this classic work, here ex-library and in sad shape, cover and several pages damaged or torn, with loose binding. Were it not a famous work donated by a well-known doctor, it probably would have been completely discarded, as was done by the Springfield (MA) Library in 1944, later to reside in the collection of G.Fred Lincks. The hardcover book in modest condition, when it can found, sells for more than $200 because to the color illustrations and over 750 pages of history, construction and application of the world-changing device, the microscope. Originally owned by Dr. C.P. Hooker, a physician who received much notariety in the 1890s as a result of cerebral surgeries published as notes in the American Journal of the Medical Sciences. Among the most important and popular works pertaining to the microscope, a rare hardcopy in poor condition, offered at just 60.00 for the adventurous book binder and collector.

GEM
QUARTZ var. LEMON CITRINE- Brazil
It has become a near-standard procedure in the gem trade to treat stones by heating, molecular deposition or other means. These large stones are no exception, showing a fairly bright, yellow to yellow-green hue due to heat treatment, available in various shapes and sizes from ovals to pears and others. Stone sizes are fairly large, ranging from about 8 cts to 23 cts each at just 2.00 per carat! We'll try to match your preferred weight and shape, but please suggest alternative shapes within a range of weights, if possible!
