CATALOG 22005 – Volume XLVII, No. 5

ARSENIC- Kusa Mine, nr. Bau, Sarawak, Borneo
Rich greyish black botryoidal masses of native arsneic richly scattered and comprising matrix, some with minor stibnite and residual white calcite. The largest are actually quite attractive pieces from this great locality. Sizes from 2cm to superb 10cm museum pieces @ 10.00, 35.00, 60.00, 85.00, and 150.00 each!

ARSENTSUMEBITE- Black Pine Mine, Granite Co., Montana
Small but colorful chartreuse-green micros of arsentsumebite lightly scattered on quartz or in vugs, occasionally with brochantite, mimetite or possibly other phases. Uncommon at the locality, this arsenate analog of tsumebite was further described in the Mineral News article of June, 2012 (the color issue is available @ 6.00 per copy, postpaid). Only a few specimens on hand, most collected in the late 1970s, sizes range from about 1.5cm to 5cm across with a few slightly larger, @ 30.00, 45.00, 75.00, 100.00 and 150.00 each, depending on quality and coverage, not necessarily size.

BELENDORFFITE- Moschellandsberg, Obermoschel, Germany
A fairly rare mineral (Cu7Hg6) found here in the Rheinland-Palantinate type locality, offered as a very tiny grain mounted in a 2.5cm probe mount and accompanied by an SEM backscatter image and quantitative chemistry. The mineral is the dimorph of kolymite and was approved in 1992 but is rarely seen in most systematic collections, occurring only in Germany (here at the type locality) and in the Rudabanya area of Hungary. One only elegantly documented specimen @ 245.00.

CALCITE- San Antonio Mine, Santa Eulalia, Chihuahua, Mexico
From an old hoard of attractive specimens acquired in 1956, these are excellent, white to translucent platy crystals, stubby rhombs and other weird forms intergrown into handsome, cauliflower-like groups of calcite without discernable matrix. Still wrapped in newspaper from the early 1960s when they last went into storage, we recently uncovered a couple of flats of these attractive specimens. We note that most are mildly fluorescent (green) under both SW and LW UV as well, sizes from about 4cm to 12 cm groups, nicely priced at just 10.00, 20.00, 35.00, 50.00 and 75.00 each, depending on size and aesthetics.

COLUSITE with PYRITE- Leonard Mine, Butte, Silver Bow Co., Montana
A pair of monster specimens recently uncovered in the warehouse, comprised of richly scattered metallic colusite intergrown with granular pyrite comprising matrix. Old Cureton specimens with trace quartz as well, comprising these large and typical ore specimens. Sizes are 13x8x7 cm @ 175.00, and a larger 16x9x7cm @ 225.00. Heavy ore material, useful as boat anchors if necessary.

CORUNDUM variety RUBY- Los Archipelago, Guinea
This west African nation, formerly French Guinea, has produced much in the way of diamonds and precious metals, but its outlying islands provide the most interesting species in the syenites and pegmatites. These corundums are rather crudely formed bipyramidal crystals without matrix, dark brownish red in color, some showing basal pinacoids with chatoyant luster, others with crude pyramidal terminations. Sizes range from about 1cm to 2.5cm, priced at just 8.50, 12.50 and 15.00 each. Limit three (3) per customer, please.

DIAMOND- Orange River, Free State, Rep So Africa
Excellent, very clean and clear pale yellow and lustrous flattened diamond macle twins without natrix, showing fine triangular outline in each gemmy stone! Great locality material and ex-David New's diamond inventory, sizes average about 3mm on edge @ just 30.00 each. Excellent micro diamonds with great form!

FERNANDINITE- Sunday Mine, San Miguel Co., Colorado
This rare vanadium mineral occurs as very richly scattered olive green powdery aggregates fully covering matrix, occasionally with other admixed phases. Colorful specimens for a rarity, sizes from about 1.5cm to 6cm @ 12.50, 20.00, 35.00, 50.00 and 75.00 each.

GLAUBERITE- Bertram Siding, Imperial Co., California Sharp flattened crystals of greyish glauberite comprising matrix, these with classic, doubly terminated monoclinic habit so well known for the species. These were collected on November 19, 1961, and were recently uncovered in a neatly wrapped flat, crystals from about 2cm to nearly 4cm across at just 8.50, 12.50 and 15.00 each.

HARADAITE- Gambatesa Mine, Genova, Liguria, Italy
Minute, emerald green crystalline platey aggregates of haradaite that have been hand-separated under a binocular microscope. A rare mineral, available as a tiny matrix-free pure mass in a capsule @ 35.00 each.

HEMATITE (micaceous)- Champion Mine, Marquette Co., Michigan
An interesting occurence of splendant, silvery grey foliated hematite scattered in/on quartz matrix, unusual for its oddly micaceous habit and high luster. Hefty specimens of good size from this classic iron mining district, ranging from about 4cm to heavy 10cm specimens @ just 10.00, 20.00, 35.00 and 55.00 each.

HEMIMORPHITE- Santa Eulalia, Aquiles Serdan, Mexico
Old stock from our early days of buying Mexican material in the 1970s, we have uncovered a flat of attractive, bladed crystals (to 1cm) of glassy, translucent to transparent hemimorphite on limonitic matrix, many with small white dolomite rhombs that help distinguish them from Mapimi material (which is also on hand). Inexpensive and moderately attractive material from 40 years ago, matrix sizes from about 3cm to 6cm across @ 7.50, 15.00, 25.00 and 40.00, depending on quality, and all with good hemimorphite crystals evident!

HENDRICKSITE - Shuster Park, Franklin, Sussex Co., New Jersey
Rich, coppery-brown micaceous masses and aggregates of hendricksite richly scattered in matrix, most associated with yellow-brown andradite and possibly other species. From the type locality of Franklin, these were collected in 1980 from was then Shuster Park, when the Fire Department (across the street) was plowing everything under to level the area, yielding this one-time uncommon sublocality find. Rich specimens and relatively large, sizes from 5cm to 8cm @ 20.00, 30.00, and 45.00 each; a few to 12cm(!!) @ 75.00 each, all exRosenbroek Collection.

HENRYMEYERITE with PRIDERITE- Eveslogchoor Mt., Khibiny, Kola, Russia
A pair of rare minerals, here intimately intergrown in an 4mm analyzed natrolite fragment, embedded and microprobed in a standard 2.5cm mount. The minerals are accompanied by two backscatter SEM images plus the detailed quantitative microprobe data and converted empirical formulae. From one of the most prolific areas in the Khibiny Massif in the Murmansk Oblast, only one superbly documented sample on hand @ 225.00.

HEULANDITE- Teigarhorn, Berufjord, Iceland
An attractive specimen of Icelandic heulandite, originally from the Natural History Museum in Reykjavik, passing through several collections before reaching us some years ago via the John Durkos Collection. The specimen shows numerous heulandite druses under pearly white crystals to 1.5 cm perched on a basalt matrix with a cut base, enabling the specimen to stand upright and display well. A classic locality, attractive, 8x5 cm @ 125.00. One only, with several labels!

JASONSMITHITE (IMA 2019-121)- Foote Lithium Mine, Cleveland Co., North Carolina
This NEW SPECIES occurs as tiny, very pale orange-brown, elongated, glassy micro crystals in vugs in a white quartz/spodumene matrix, occasionally with other species. Formula: Mn2+ZnAl(PO4)4(OH)(H2O)2*3.5H2O - monoclinic, IMA # 2019-121. All are accompanied by a signed Jason Smith label, and most of the higher priced specimens will have multiple arrows highlighting the species. Note: 30x or higher recommended, priced according to coverage, not matrix size, specimens from 1.5cm to 3.5cm @ 500.00, 750.00 and one at 1250.00, among the best of species! Type locality, of course, only five available.

JEPPEITE- Walgidee Hills, Noonkanbah, W.A., Australia
Small black aggregates of this rare species richly scattered in a 2 ml vial. This is from the original descriptive work on the locality, supplied as pure, separated material originally provided by the famous geochemist and textbook author, the late Brian Mason, who also had two minerals named after him during his tenure as curator at both the American Museum of Natural History and at the Smithsonian. A rare oxide mineral from an excellent locality with superb provenance, offered @ just 45.00 per vial of pure material.

JIXIANITE- Anderson-Apache Mine, Hidalgo Co., New Mexico
This rare mineral, described in 1979 from China, occurs here as crimson red, micro druses comprised of minute octahedra scattered on matrix, potentially associated with green cuprotungstite, bromargyrite, brightlyfluorescent scheelite etc. The occurrence was described in the October 2004 issue of Mineral News. Now considered possibly as an ill-defined member of the elsmoreite group of minerals requiring structure work,these are from one of the very few reported localities in the world and he only U.S. locality, all are pedestal mounted specimens in a micro box and make interesting and colorful MMs at just 55.00 each.

KAYROBERTSONITE (IMA 2015-029)- Foote Lithium Mine, Cleveland Co., North Carolina
This relatively new species occurs as somewhat wispy, snow-white needle-like clusters of tinyt micro crystals on matrix, some of the better samples with mangangordonite, both species from the type locality. Formula: [MnAl2(PO4)2(OH2)(H2O)9]*2H2O, triclinic, IMA 2015-029. The mineral, named after the late Kay Robertson, was originally thought to be the Al-analog of strunzite, later determined to be the (OH)-analogue of nordgauite after extensive study. Author's material, of course, specimens from 1.5cm to 3.5cm @ 200.00 and 350.00 each, depending on richness and associations.

LITIODIONITE- Vesuvius, Campania, Italy
A tiny fragment of this rare CuNaKSi4O10 species in a stoppered vial, old material ex-Cureton, once known as lithiodionite and renamed in 2014. Only a few small, very pale blue masses on hand @ 55.00 each.

MAGNESIOCHROMITE- Red Pit Mine, Lancaster Co., Pennsylvania
Black, sunmetallic masses and grains of magnesiochromite are disseminated in a light green antigorite/rock matrix. A well documented PA occurrence for this relatively uncommon spinel group mineral. Generously sized samples from 4cm to 7cm across @ just 15.00, 25.00 and 40.00 each.

NEYITE- BC Mo Mine, Kisault, British Col., Canada
From the type locality for the species, we have a few small specimens of this uncommon Ag-Cu-Pb-Bi-sulfosalt mineral, here as steely-grey, metallic masses scattered in white quartz matrix. Old Cureton material, small fragmnets about 5mm @ 25.00, and a pair of very rich 2.5cm thumbnails @ 125.00 each. List alternates!

PARADAMITE with LEGRANDITE- Ojuela Mine, Mapimi, Durango, Mexico
Excellent golden yellow triclinic crystals of the rare mineral paradamite forming four globular balls on limonitic matrix, associated with superb, glassy flattened sprays of legrandite crystals as well! The specimen was pictured in Mineralogical Record [figure 118, page 80 of V.34 No. 5 (2003)], ex-Marty Zinn, ex-Martin Jenesen Collection. An outstanding thumbnail specimen about 3cm tall @ 3500.00. One only, probably the best I have ever seen!

PYRITE pseudo @ PYRRHOTITE- Hecla Rosebud Mine, Pershing Co., Nevada
Collected in 1997 and 1998, these are excellent, flattened pyrrhotite crystals that have been replaced by pyrite (and to a lesser extent, marcasite), forming attractive and quite distinctive pseudomorphs from this excellent locality. Some appear almost rosette-like, while a few will have tiny white barites perched on the flattened platy crystals. These are from several locations within the mine: 22 Stope, #2 Decline, 42 Stope, 4596 ft level etc, all
precise location in the mine will be supplied with each specimen. Superb thumbnails, ex-Martin Jenesen Collection, XRD-confirmed, all in the 2.5cm size range @ 30.00, 35.00 and 45.00 each, depending on aesthetics and associations.

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. Old material first described in 1922 in American Mineralogist, early work on the specimens showed about 15 different species make up the sands, with approximately 37% residual calcite remaining in these weird crystal groups. The location is now part of a National Natural Landmark and is closed to collecting. Neat specimens from about 4cm to 8cm across @ just 15.00, 25.00, 35.00 and 45.00 each.

ROSSMANITE- Lastovicky, Moravia, Czech Republic
This relatively rare member of the tourmaline group occurs as small, pale tan-pink to nearly clear elongated crystal aggregates, some with minor matrix. Material from one of the authors, this relatively new tourmaline is small but moderately appealing. Formula: [](LiAl2)Al6(Si6O18)(BO3)3(OH)4. Small crystal sections from about 4mm up to 1cm @ 45.00, 75.00 and 125.00 each.

SALEEITE- Lake Boga Quarry, Victoria, Australia
Yellow-green, somewhat flattened tiny (1mm) platy aggregates of this unusual uranium mineral sparsely scattered on granitic matrix. Brightly fluorescent material from an excellent locality acquired about 25 years ago, matrix sizes from 2.5cm to 6cm across @ 20.00, 30.00, 45.00 and 65.00 each.SAMPLEITE- North Parkes Mine, Goonumbla, NSW, Australia From the Endeavour 26 Open Cut at the locality, these are exceptionally bright, electric blue flattened sampleite
aggregates in small sprays to 5mm across scattered on rock matrix. Coverage is light but the material is superb for the species, some of the most colorful we've seen. Marvelous locality material, specimen sizes from 3cm to 6cm across, priced according to richness, at 15.00, 25.00, and 45.00 each. Neat!

SATIMOLITE- Satimola-Salistock, Kazakhstan
Snow-white rounded masses and aggregates of satimolite to several millimeters scattered in clay-polyhalite rock matrix. Holotype material from the author, available as small fragments from 0.5 to 1.2cm @ 40.00, 55.00 and 75.00, or as a few 2cm to 3cm better matrix samples @ 100.00 and 150.00 each.

SCAPOLITE (purple!)- Templeton, Quebec, Canada
Lavender pieces of massive scapolite, the coloring being fairly unusual in this otherwise common mineral. Old Ward's Natural Science stock, rich and solid masses with vibrant color, sizes ranging from 2.5cm to 5cm @ only 10,00, 20.00 and 30.00 each.

SCHLOSSMACHERITE on CERULEITE- Mina El Guanaco, Antofagasta, Chile
Pale green, micro aggregates of rather lean schlossmacherite lightly scattered on excellent, turquoise-blue massive ceruleite matrix, occasionally with minute drusy crystals of mansfieldite as well. Good association pieces from a classic area, sizes range from 1.5cm to 2.5cm @ 20.00, 30.00 each, a few larger to 5cm @ 45.00 and 65.00 each. Attractive for the ceruleite association!

SILVER (Native) etc.- Black Pine Mine, Granite Co., Montana
Native silver confirmed as coming from the Black Pine mine has ever been particularly attractive, typically noted as "seen rarely as paper thin fracture fillings" by Dave Waisman in the Mineralogical Record article back in 1992 (Vol. 23, No. 6). The locality update published in 2012 in Mineral News (Vol. 28, No. 6) also made no mention of additional silver specimens from the locality. However, we have recently acquired an old collection of Black Pine material rich in native silver as well as other species previously unreported from the locality, all to appear in a future issue of Mineral News. This material, collected in 1979-1984, revealed a fair number of native silver samples. True to form, many depict thin, filmy masses of tarnished native silver on matrix, typically with chrysocolla, malachite and other species, as well as a few richer specimens that showed bright, tiny arborescent native silvers on tetrahedrite-group samples and occasionally with other uncommon associations. We have reference samples of differing qualities ranging in size from small TNs to nearly 6cm, priced at just 15.00, 30.00, 50.00, and 75.00, with a few higher as well; please inquire, but don't miss this native element rarity from this complex, mineral-rich locality that is now part of the Montana Environmental Custodial Trust! An article about the silvers appears in the August issue of Mineral News.

TACHARANITE- Jeffrey Mine, Asbestos, Quebec, Canada
Pure white masses of tacharanite well scattered over crystalline pectolite matrix. From an old find, these are quite rich for both species, and sizes range from about 3cm up to nearly 6cm across @ only 20.00, 35.00 and 55.00 each.

TENORITE- Irish Mag Shaft, C&A Mine, Bisbee, Arizona
From the famous Calumet and Arizona Mine in Bisbee, we have obtained a small lot of very old tenorite specimnes. These as pure and solid, black shard-like masses of this copper oxide mineral completely comprising matrix. Similar to Harvard's illustrated specimen on MinDat, these are exceptionally rich, classic
specimens from teh Irish Mag Shaft, ex-A.E. Seaman Mineral Museum, sizes ranging from about 2.5cm to 5cm across @ 10.00, 25.00 and 45.00 each;

THORUTITE- Buckwheat Dump, Franklin, Sussex Co. New Jersey
A rare mineral at Franklin, here as tiny brownish black, somewhat resinous masses and rods sparsely scattered in dolomitic matrix. From an older find, ex-Rumrill collection, specimens mounted in standard TN boxes from 0.5cm to 2cm across @ just 20.00, 35.00 and 50.00 each.

TREMOLITE- ACTINOLITE- Paakkila Mine, Tuusniemi, N. Savonia, Finland
A tall, columnar example of greyish tremolite as flattened, elongated rods, showing associated actinolite that has altered to a fibrous, brownish asbestiform surface, with minor talc and vermiculite at the base of the specimen. Ex-Rosenbroek and originally labelled simply as actinolite due to the fibrous nature of portions of the piece, the specimen is 17x7cm @ 75.00; the best we have seen from this uncommon locality!

VAESITE- Castelluccio di Moscheda, Modena, Italy
This rare nickel sulfide minerals occurs as extremely small (<1mm) black masses sparsely scattered in matrix, some associated with minor millerite sprays, and all specimens with a pinpointing arrow. Collected circa 1980 and recently uncovered in our warehouse, specimens from about 2cm to 4cm across @ 45.00, 60.00 and 85.00, depending on quality.

WULFENITE- Ahumada Mine, Los Lamentos, Chi., Mexico
From the classic finds of the 1960's, we have located an old hoard of superb, wulfenite specimens, here as thick, tabular butterscotch-orange to dark brown tabular crystals either free standing or perched on contrasting white and red-brown matrix. Attractive material no longer available, a wide range of sizes and qualities are on hand, most are neat and inexpensive TN's and miniatures from 1.5cm to 3.5cm samples @ 10.00, 15.00, 20.00 and 30.00 each. We also have a few larger matrix specimens available up to 1250.00, so please inquire!

CATALOG 22004 – Volume XLVII, No. 4

AERINITE- Estopinan, Huesca, Aragon, Spain
Rich blue masses of aerinite well-scattered throughout rock matrix, perhaps from the Soriana Quarry. The blue color of the mineral prompted its use in pigments in many European murals, and Estopinan del Castillo is the type locality for the species! A chemically complex carbonate-bearing silicate, specimens from about 2cm to 3.5 cm @ just 12.50, 20.00 and 35.00 each. Excellent color!

AMBER with INSECTS- Danzig Region, Poland
Rich honey-orange transparent amber pieces, each with a tiny included winged creature! Hand-selected from a large collection, these are lightly polished and quite fascinating, each accompanied by its own color photograph of the included insect! Sizes average 1.5cm to 3cm long, and are only 20.00, 25.00, 30.00 and 40.00 each, depending on size and the quality of the bug and the amber!

APACHITE- Christmas Mine, nr. Hayden, Arizona
Pale greenish blue to blue masses and radiating balls of scattered apachite on typical Christmas Mine smectite matrix, uncouthly with other species such as kinoite, flurapophyllite etc. Generously sized specimens from 2.5cm to 8cm across, most with modest micro potential as well @ 20.00, 35.00, 50.00 each and 95.00 for the largest one. A moderately rare species from this, the type locality. Super!

ARGYRODITE- Santa Rita Mi, Capillitas, Calamarka Argentina
This rare silver-germanium sulfide occurs as black, sooty metallic masses to 6mm scattered om pale pink rhodochrosite veins and in exposed vugs in quartz/sulfide ore matrix. From the La Argentina vein in the mine, commonly grouped as "Capillitas Mines ', extensively studied in 2009. Overall size is a little over 5x4 cm @ 150.00. One only.

BABINGTONITE- Lane Quarry, Westfield, Massachusetts
Interesting black babingtonite crystals and heavily etched aggregates nicely scattered on drusy quartz crystals lining large exposed vugs and seams in matrix. Classic eastern U.S. locality material, quite good, with matrix sizes from 3cm to 8cm @ 20.00, 30.00, 45.00 and 60.00 each depending on size and coverage.

BARITE- Hecla Rosebud Mine, Pershing Co., Nevada
From the second find of very strange barites from this locality! Several years ago, a small batch of white, opaque rhombohedral-appearing barites were found here, and now, some superb, larger crystals! These, too, have the very odd rhombohedral habit, but these are considerably larger (single crystals to nearly 3.5cm on edge!) and are also in attractive, lustrous groups that look more like calcite! A large variety of specimens available: single crystals from about 1.5cm to 3.5cm @ 15.00, 25.00 and 40.00, attractive groups of smaller crystals from 4cm to 7cm overall @ 35.00, 50.00 and 75.00 each. Nice!

BISMUTH- Vilaque River, La Paz Departmnet, Bolivia
Excellent water-worn stream pebbles of nearly pure native bismuth without matrix, these hand-selected for size and quality. Some may have included rare phases (ikunolite has been found, for example) but we have elected not to cut these into polished sections for detailed study, offering them simply as "native bismuth nuggets"! Sizes range from flattened 2.8cm placers up to large, thick nearly 5cm stones @ 40.00, 60.00, 85.00 and 125.00

CHALCOSTIBITE- Rhar el Anz, nr. Casablanca, Morocco
Dark greyish black masses and elongated crystal aggregates of this uncommon sulfosalt with minor matrix, many partially altered to (or pseudomorphed by) azurite and/or malachite. Rich, old specimens, sizes from 1.5cm to 3.5cm @ 30.00, 45.00 and 75.00 each.CINNABAR in CHALCEDONY- Buckskin Mountain, Humboldt Co., Nevada Originally labeled as "Buckskin Peak Mine" in the National District, this material is likely from the area at Buckskin Mountain near the Buckskin National Mine mentioned in Mindat, although the local mineralogy is only listed there under "Buckskin Mountain". NBMG Special Publication 13 lists the "Buckskin Quicksilver Mine" a possible locality, but it, too, is not noted in Mindat. Nonetheless, the material is classic red cinnabar, scattered in a silicified rhyolitic "chalcedony" matrix, certainly useful as reference material and as potential cabochon material as well. Lindgren noted the Buckskin Peak locality in 1915 (USGS Bulletin 601), but he did not find cinnabar as he did not visit the locality in his paper re: the National District. In any case, hefty hand specimens of what is occasionally called "opalite", chunks from 5cm to 12 cm across @ just 10.00, 20.00, 35.00 and 45.00.

FELSOBANYAITE- Clifton Hill, Brighton, Sussex, England
This former one-locality species is found here as chalky white masses richly distributed through a bladed gypsum and clay rock. Rarely offered material from an old locality, available from 2cm to nearly 8cm @ 20.00, 35.00, 50.00 and 85.00 for the largest!

FROODITE etc.- Talnach Cu-Ni deposit, Norilsk, Russia
A superb 1.5cm ore sample in a polished 2.5cm probe mount, accompanied by two SEM backscatter images and full quantitative chemistry for both froodite and soboleveskite, a pair of rare Pd-Bi minerals! This Siberian locality has produced similar assemblages with ten or moree species in a single probe mount, and one can expect silver, pentlandite and other species present in the sample! Don't miss this well-documented rarity @ just 185.00! One only!

GAGARINITE-(Y)- Katugino, Irkutsk Region, Russia
Old material from a Russian museum collection, here as dull rose colored masses scattered in dull quartz matrix, occasionally with massive thomsenolite. Unattractive material but quite good for the species, specimens from about 1.5cm to 3cm across @ 35.00 and 50.00 each; a 5cm sample @ 125.00.

GALENA- Pasminco Mine, Broken Hill, NSW, Australia
A large hand specimen of "stressed" galena, weighing over 4 pounds and presenting as silvery-grey metallic masses in flattened platy aggregates and banded streamers showing no apparent cubic cleavage. The greatly reduced evidence of cleavage is typically due to trace elemental impurities that affect the structure. Minor fluorescent calcite (SW-red) is also present in tiny amounts, the specimen obtained from the mine geologist in 1992. A odd habit for an otherwise common mineral and an excellent example of this very rich occurrence, overall about 10x7x6 cm @ just 55.00. Heavy!

HYDROXYAPOPHYLLITE-(K)- Aris Quarry, Aris, Namibia
Minute, glassy pale yellow crystals of hydroxylapophyllite sparsely scattered in vugs in matrix, better pieces associated with fibrous balls of tupersuatsiaite and possibly other species. Good micro potential, sizes from 2 to 4.5cm @ 25.00, 40.00, and 55.00.

KAMPFITE- Esquire #1 Claim, Rush Creek, California
This moderately NEW SPECIES occurs as pale bluish grey grains and aggregates, typically at the margins of larger sanbornite plates. Approximate formula: Ba6[(Si,Al)O2]8(CO3)2(Cl,O,H2O)2 - hexagonal. Named for Tony Kampf, retired curator at the LA County Museum. Specimen sizes range from about 0.8cm to nearly 4cm @ 45.00, 60.00, 85.00 and 125.00.

KESTERITE- Cligga Mine, St. Agnes, Cornwall, England
Metallic masses of kesterite sparsely scattered in rock matrix, occasionally with other sulfides. Formerly known as "iso-stannite" from this locality, we have a number of interesting matrix specimens, sizes from 1.5cm to nearly 8cm across @ 10.00, 20.00, 35.00, 50.00, 75.00 and 100.00 each, the larger specimens showing some crude crystallization as well.

LINDQUISTITE- Jakobsberg Mine, Varmland, Sweden
Minute black plates of this moderately rare species scattered in and on matrix. A submetallic Pb(Mn,Fe,Mg)Feoxide, priced according to size and richness, matrix pieces from small fragments up to a superb 3cm specimen @ 45.00, 85.00, 150.00 and 200.00 each. Type locality material; please list alternates!

MACFALLITE with ORIENTITE- Manganese Mine, Copper Harbor, Michigan
From the type locality for macfallite, these manganese silicates occur as silky intermixed fibrous aggregates in calcite matrix. Typical specimens contain pinkish brown macfallite, associated with dark reddish brown orientite,often with dull black braunite and more lustrous pyrolusite. An interesting and complex assemblage, sizes from 1.5cm to 5cm @ 15.00, 30.00 and 50.00 each. Old material!

MAGNESIO-FOITITE- Berezovskoye Gold Deposit, Ural, Russia
From this famous locality, we have obtained a small lot of this new and rare member of the tourmaline group, here as pale grayish to greenish blue micro rods and needles to 5mm scattered in seams in matrix. Analytical studies have shown the cores of the rods to be consistently magnesiofoitite, while some of the peripheral rims of the needles quantify as dravite! A neat discovery, matrix sizes from 2cm to 3.5cm @ 35.00, 50.00 and 65.00 ea.

MAGNESIOCHROMITE- Red Pit Mine, Lancaster Co., Pennsylvania
Black, sunmetallic masses and grains of magnesiochromite are disseminated in a light green antigorite/rock matrix. A well documented PA occurrence for this relatively uncommon spinel group mineral. Generously sized samples from 4cm to 7cm across @ just 15.00, 25.00 and 40.00 each.

MAKATITE- Aris Quarry, Aris, Namibia

OSCARKEMPFFITE- 264 level, Colorado Vein, Animas Mi. Bolivia
This exceptionally rare silver mineral was described recently (IMA 2011-029, published in 2016) from old material that had been collected circa 1930. It occurs as small geryish-black, metallic inclusions in tetrahedrite/stannite ore. We offer small, microprobed aggregates embedded in a quartered leucite probe mount @ 450.00. List alternates!

PLUMBOJAROSITE (ARSENIAN)- Lomo de Toro Mine, Zimapan, Mexico
Earthy nodules of very pure yellow-brown arsenian-plumbojarosite richly filling 5cm tall stoppered vials. Old material from many years ago, similar to that used for the intensive study of the thermal decomposition of the mineral published in Canadinan Mineralogist (Vol. 47, No. 3) in 2009, confirming it as the arsenianplumbojarosite variety of the species. Under the SEM, the material is shown to have a minute, platy habit, appearing powdery otherwise. Rarely available today from this rich locality, each 5cm filled vial is just 15.00.

PODLESNOITE - Kirovskii Mine, Khibiny, Kola, Russia
This rare mineral occurs as excellent, water-clear, micro prismatic crystals up to 3mm tall well scattered in radiating groups and clusters nicely perched on matrix. Many are doubly terminated and highly vitreous, often sitting among well formed natrolite crystals, some with minute but perfect clusters of ilmenite as well. Formula: BaCa2(CO3)2F2, orthorhombic, IMA #2006-033. The mineral is also nicely flurescent pinkish orange under SW UV, and is named for Aleksandr Semenovich Podlesnyi (b.1948, now deceased), Russian amateur mineralogist and professional miner. Type locality, of course, for this new structural type (space group Cmcm) remotely related to carbonates of the aragonite group. Well crystallized, fine micro's and fluorescent as well: what could be better for a new species?

List
alternates!

FLUORAPOPHYLLITE-(K)- Jalgaon District, Maharashtra, India
About 20 years ago, we purchased over 14,000lbs of crated zeolites. In the ensuing years, crates were opened, material sold, and we kept a small stash of exceptional pieces for "a rainy day". While the supply of zeolites has not waned significantly, the prices for fine speicmens has skyrocketed. We are offering a few large, decorator-sized specimens of water-clear fluorapophyllite-(K) on minor matrix, all with full coverage, little if any associated species, and just really attractive, glassy show pieces that average from 25cm to 30cm long and half as wide, each for just 495.00 per specimen.

BERYL var: EMERALD w/ SCHEELITE- Dayakou Mi, Malipo, Wenshan, Yunnan, PR Ch
Dark green masses and crude crystals of emerald scattered in matrix, typically consisting of feldspar, quartz and/or dark chloritic rock. Interesting for the locality, we have a few samples averaging 4cm across at just 20.00 each, and a couple showing associations of yellow masses of brightly fluorescent (SW blue-white) scheelite that we recently analyzed at just 25.00 each.

BITUMEN in GEODE- nr. Niota, Hancock Co., Illinois
A quartz geode half with the interior richly coated with tiny black petroleum-like balls. "Bitumen" is used here as a generic name for natural hydrocarbon (petroleum) substances that are virtually solid in form, not unlike asphaltum, crude oil or pitch. The geode half has an apparent repair line running through it, overall about 4.5cm across the opened face at 25.00. List alternates!

BORNITE coating PYRITE- 1400' L, Cole Shaft, Bisbee, Arizona
From material described in the February, 2020 Mineral News article, these are small pyritohedrons fully coated by a thin film of greyish, metallic bornite. Extracted from the 1400' level of the Cole shaft in the distant past, well-formed pyrites from the locality are rarely encountered. Single crystals and groups range from 4mm to 7mm across, all are matrix free and very sharp, and we offer a suite of three different for just 10.00 per lot; we'll even include a copy of the article for those of you who are not Mineral News subscribers!

While there is no lack of Chinese calcite these days, we uncovered a small lot of brilliantly fluorescent (SW and LW, blue-white) calcite specimens that also show good phosphoresence after the UV light source is removed! The crystals are frosty, white rhombs with the crystal edges turned upwards, giving these closely intergrown specimens additional appeal, regardless of the excellent fluorescent response. Only a few on hand, generous sizes about 7cm long, at just 20.00 each.

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.

A few larger available - inquire! One monster @ 750.00

COPPER- nr. Calumet, Houghton Co., Michigan
Crudely crystallized arborescent masses of native copper with little attached matrix, these acquired in Calumet in 1959, well before the great miners’ strike of 1968 that shut down all operations. Examination under the scope occasionally finds minor prehnite, epidote or other unidentified secondary phases tucked among the copper or on its surface. Interesting natural "scuptures", sizes from about 2.5cm to 7cm across @ 15.00, 25.00, 40.00 and 65.00 each. Neat, older specimens!

CUPRONEYITE with COSALITE- Baita (Rezbanya), Nucet, Bihor, Romania

Sizes are typically around 6x4mm @ just
145.00 each. Nice!

DRAVITE (Vanadium-rich!)- Merelani, Arusha, Tanzania
From the original find of colorful, bright green (!!) dravite tourmaline in matrix from this prolific locality. Most of the dravites are transparent and in the 5mm to 15mm size range with excellent color, although none are perfect or particularly well-terminated. All are perched in a complex skarn matrix that often shows much variable fluoresence due to phlogopite (yellow FL), diopside (blue-white FL) and included quartz (green FL) in many samples, along with minute pyrite and other phases. Surprisingly, about 20% of the better samples also show massive yellow native sulfur (!!), also relatively new for Tanzania. Specimens are priced based on overall size and quality of the dravite and its associations, not on ovcerall size, ranging from about 2.5cm up to nearly 5cm @ 50.00, 75.00, 100.00 and 125.00 each.

Tiny micro specimens mounted on adhevsive disks showing the two new minerals @ 275.00 each. Type locality material!

FLUORAPOPHYLLITE-(K)- Jalgaon District, Maharashtra, India
About 15 years ago, we purchased over 14,000lbs of crated zeolites. In the ensuing years, crates were opened, material sold, and we kept a small stash of exceptional pieces for "a rainy day". While the supply of zeolites has not waned significantly, the prices for fine speciens has skyrocketed. We are offering a few large, decorator-sized specimens of water-clear, prismatic fluorapophyllite-(K) crystals on minor matrix, all with full coverage, little if any associated species, and just really attractive show pieces that average from 25cm to 30cm long and half as wide, each for just 495.00 per specimen.

Old material, associated with a variety of other Ba-rich silicates, specimens from 2cm to 4cm @ 15.00, 25.00, and 40.00.

MOORHOUSEITE ps @ BIEBERITE- Fontana Rossa Mine, Corsica, France
This uncommon species occurs as dull pinkish masses sparsely scattered on matrix, here as pseudomorphs after bieberite. Known from about a dozen localities worldwide, we suspect the mineral is somewhat more common but has escaped detection due to its unappealing presentation. Specimens range from about 1cm
to 2cm @ 30.00, 55.00 75.00 each. Ex-Cureton material!

NASTROPHITE- Iron Mine, Kovdor Massif, Kola, Russia

We have a range of singles, priced according to crystal size from 1.5cm @ 150.00, 2.5cm @ 250.00, one complex and intergrown group about 3x3cm @ 350.00, and one exceptional 4x6cm complex single @ 600.00. A classic eastern U.S. locality in Rockbridge County, rarely available in this quality!

QUARTZ variety AMETHYST- Bochovice, Trebic, Vysocina Region, Czech Republic
A rather strange specmen, here as alternating chevrons of white and amethystine quartz forming a dense matrix for a handful of crystallized amethyst points to 3cm, some with smoky edges on transparent faces. The piece is banged up and therefore begs to have its edges polished to display the well-formed chevron
pattern, but it is an interesting specimen without resorting to glitzing it up, acquired from a Czech geologist many years ago. A large and heavy specimen, overall size about 11x8x7 cm @ 60.00. One only!

ANTHOPHYLLITE- Falun, Dalarna, Sweden
Dark greyish, flattened radiating aggregates intimately intergrown and embedded in biotitic, shistose matrix. Better known for its sulfides, the Falun region of Dalarna has produced over 100 different species to date, including seven different type specimens. Represenative samples with typically rich anthophyllite sprays, specimens from about 2.5cm to 10cm across at just 8.00, 15.00, 30.00, 45.00 and 65.00 each, the larger samples quite heavy!

ARAGONITE (Blue!)- Wenshan Mine, Yunnan Province, PR China
Attractive, pale blue botryoids, druses and/or stalactitic aggregates of aragonite comprising matrix, these showing excellent color for the mineral. This area was also the producer of the blue, botryoidal hemimorphite specimens that resembled classic Kelly smithsonite seen some years ago. Very pleasing color and surprisingly inexpensive, specimens average 4cm across at just 10.00 and 15.00 each!

BARITE- Dee North Mine, Elko Co., Nevada
Attractive, pale golden yellow transparent barite crystals to 2cm perched on matrix, most showing excellent, elongated chisel-shaped habits. Attractive and very reasonably priced groups from a 2001 find, sizes range from 2cm TNs to 5cm across @ 10.00, 20.00, 30.00 and 45.00 each, priced according to quality, not size. Quite nice, and featured in Mineralogical Record (Vol. 33 #3) shortly after its discovery!

BARRERITE- Kuiu Island, Alexander Archipelago, Alaska
Platy, white to slightly pinkish spear-shaped orthorhombic crystals and aggregates of the uncommon zeolite barrerite, scattered on matrix, some associated with minor quartz, heulandite and possibly other zeolites. This material is visually similar to stilbite, and microprobe and X-ray work on the material has shown it to be the rare zeolite barrerite, discovered here in 1984. These specimens were originally collected by the former claim holder, Istvan Toth, the major source of all Alaskan barrerite for many years, the locality often attributed to Rocky Pass. Since the borough designations in Alaska are changing, we no longer use "Sitka" as the borough in our labels. Sizes from about 3cm to 8cm across, priced lower than our last offering in 1998, at just @ 15.00, 25.00, 40.00 and 65.00 each, based on quality. Moderately attractive and likely the finest barrerite occurrence in the world!

BOTTINOITE- Dornberg, Ramsbeck, Sauerland, Germany
Pale bluish green micro glassy aggregates of translucent bottinoite sparsely scattered on matrix but showing moderately good tabular trigonal form. This uncommon species (formula: NiSb2(OH)12.6H2O) and locality was noted as best of species in Mineralogical Record back in 1998. Associations include dolomite, chalcopyrite and/or quartz, only a few specimens on hand averaging 2.5cm 65.00 each, less expensive now than in 1994!

These are the last of our good fluorescent (bright yellow-SW) specimens, not lean throwaways! Sizes from 4cm to 7cm across, priced according to amount of esperite present, not overall size, @ 50.00, 75.00, 100.00 . Many from Nick Zipco and other collections acquired in the 1980s and 1990s.

FERRO-FLUORO-PEDRIZITE- Tastyg Pegmatite, Sutlug River, Tuva Russia
From the type locality and type specimen for the species, we have a few tiny single crystal shards of this rare amphibole group mineral, here as thin, bluish-grey aggregates without matrix. Originally described as IMA 2008-070, the mineral has undergone name changes as the amphibole groups have been variously redefined, this species one of the lithium-rich, monoclinic phases. Only several encapsulated crystals to 1mm on hand @ 85.00 each. See our image on www.mindat.org

FERROERICSSONITE (IMA#2010-025)- Esquire #8, Big Creek, Fresno Co., Califor
This moderately rare species occurs as dark reddish brown vitreous, foliated aggregates and striated blades sparsely scattered in quartz matrix, some associated with anandite, gillespite, titantaramellite and possibly other species. Formula: BaFe2Fe3+O(Si2O7)(OH), monoclinic, IMA #2010-025. Author's material from the type locality, specimens range from about 0.8cm to nearly 2cm across, priced according to coverage and size @ 95.00, 125.00 and 155.00 each for the richest.

FLUORAPATITE-CLINOFLUORAPATITE- Siglo Viente Mine, Llallagua, Potosi Bolivi
Small, glassy white elongated aggregates of fluorapatite sparsely scattered on yellowish wavellite matrix, some with minor quartz and/or cassiterite. Minor chemical substitution has demoted this normally hexagonal mineral to lower monoclinic symmetry, hence the "clinofluorapatite" varietal name. This mineral oddity is best seen under both SW and LW UV, as it fluoresces a bright peach color. Specimens range from TNs @ 15.00, 5cm @ 40.00, and a few well-formed, more showy 8cm specimens @ 75.00 each. Only a few of each, so list alternates!

FLUORITE (RED OCTAHEDRONS!!)- Huanggangliang Mine #6,Inner Mongola, PR China
See the special printed flyer accompanying this list! Some of the best are we have are pictured here, although there are others available starting at $1200 to $2000. As featured in August issue of Mineral News, don't miss these; probably the finest specimens China has ever produced, and certainly the best red to pink fluorite in the world, far superior to those of Switzerland and Peru! We can also supply images for serious inquiries, just specify your desired price range..

GALENA- Huanzala Mine, Ancash, Peru
This Peruvian locality is best known for its fluorites, but we recently located several flats of massive galena collected in the early 1970s from the locality. The massive material is unusual because it does not show galena's distinct cleavage very well, the result of trace elemental impurities that affect the prevalence and degree of cleavage in these "structurally stressed" specimens. Our EDS work indicates trace silver is the culprit. Specimens range from 2.5 to 5cm across @ just 5.00, 7.50 and 12.50 each. We can also supply a lot of 10 assorted at a greatly discounted price of just 50.00 per lot!

GREENALITE- La Union, Murcia, Spain
Rich, solid murky green masses of greenalite largely comprising matrix, occasionally with minor siderite and/or galena, and both obvious when present. An unusual member of the kaolinite-serpentine group, these from an excellent European locality. Sizes average about 2.5-3cm @ just 20.00 each, a few considerably larger to 6cm+ @ 75.00 each.

HILAIREITE- Poudrette Quarry, Mont St. Hilaire, Canada
From the type locality for the species, we have several nicely mounted specimens in black micro boxes that show well formed, pale brown to nearly colorless trigonal crystals of this rare mineral. The mineral is typically associated with analcime, natrolite or other phases, and all are fine micros @ 85.00 each. Limited availability!

JUABITE (Portion of Type)- Centennial Eureka Mine, Juab Co., Utah
A portion of the type specimen, collected in 1992 by co-author Martin Jensen and part of the sample X-rayed by Andy Roberts at the Geological Survey of Canada who then described the new mineral. The sample is a tiny, sub-millimeter, deep green crystal in a capsule and mounted in a TN box with Andy Roberts' handwritten label of UKCE-11 that would eventually become the type specimen for juabite. Ex-Martin Jensen collection # MJ7172, @ 1500.00. One only, a unique scientific specimen!

KAWAZULITE w/ HESSITE etc.- Kochbulak Au-Te Deposit, Sughd, Tajikistan
A 2.5cm probe mount, accompanied by a pair of SEM backscatter images and a chemical analysis, shows kawazulite surround by hessite in a quartz-terahedrite matrix, associated with several other species. Interestingly, the locality is often noted as being in Uzbekistan (even in several professional papers), but
mistakenly so because the only access road to the deposit is via Uzbekistan to the NW. The actual deposit is across the border in Tajikistan, but cannot be reached via that country's roads! We believe the sample is unique as the first (and perhaps only) reported occurrence of the species in the deposit. Only one, elegantly documented specimen on hand @ 245.00.

KAZAKOVITE with KAPUSTINITE- Palitra Pegmatite, Kedykverpakhk Mt Russia
This rare species occurs here at this prolific locality as very thin, tiny yellowish brown rims surrounding pods of purplish red kapustinite, itself yet another relatively new species from this superb locality! A rare Na-Mn-Ti silicate, we have just a few specimens on hand, sizes from 2cm and 3.5cm across @ 100.00 and 225.00 each.

KIRCHHOFFITE- Dara-i-Pioz, Tajikistan
This one-locality species is a significant rarity, a cesium-boron silicate, and only one of the two known species to offer this chemical combination. Formula: Cs(BSi2O6), tetragonal, IMA 2009-094, among the rarest of all zeolite group minerals known. Named for Gustav Kirchhoff, co-discoverer of the element cesium. The mineral is a minute inclusion in pectolite, carefully embedded in a 2cm probe mount, accompanied by a SEM backscatter image and X-ray spectra. One only @ 350.00.

KOTULSKITE + UNK Pd-Pb-Te-S etc- Federovo-Pansky Massif, Murmansk, Russia
Commonly known as the Pana Layered Gabbro-Norite Complex, this Kola Peninsula locality has produced a large number of PGM minerals, many quite rare and difficult to obtain. We have a single 2.5cm probe mount with four embedded ore samples, accompanied by 25 pages of analaytical results, including 11 SEM images and analytical data for eleven different sites among the four ore samples. Kotulskite was confirmed in at least 4 analyses, a Pd-bearing gersdorfite in 2, a Pt-Pd-gersdorfite in three more, as well as a telluropalladinite, a PtPd-bearing cobaltite (new for the locality) and an unknown phase (also new) noted as a Pd-Pb-Te-S mineral, as yet not named or described. Full chemistry accompanies each identification, as well as a pinpointing SEM. Only one mount available, superbly documented with numerous pages, at 375.00 for the lot.

LEIFITE with RHODOCHROSITE etc.- Poudrette Quarry, Mont St. Hilaire, Canada
Among the most prolific localities in the world, Mont St. Hilaire has yielded over 400 different species, many found as aesthetic micro crystals. We have several samples of leifite as transparent to white micro crystals scattered on matrix, typically with disk-shaped, dard rhodochrosite, needles of aegirine, occasionally fluorite and even bastnaesite-Ce on our best sample. Specimens rage from about 2cm to 3cm across, priced according to coverage, at 85.00, 125.00 and 175.00 each. For those that want the giant leifite samples, we have two rather extraordinary examples of this fairly rare mineral in lustrous, hemispherical groups that appear as smooth balls on the top surface, but are actually the terminations of densely-packed radiaiing crystals beneath! A great, partial ball as a hemispherical thumbnail about 3cm tall @ 395.00; one larger 4.5x3.5 complex and astounding monster with micro, pink serandite and other potential associations @ 1500.00. List alternates!

MIMETITE etc.- Mapimi, Durango, Mexico
We recently uncovered several flats of Mapimi mimetite, these from the early 1970s and comprised primarily of micro botryoids of yellow to greenish mimetite lightly scattered in/on limonitic matrix, some with transparent calcite, possible wulfenite and potentially other species. Much micro potential here, and quite inexpensive with specimens from about 2.5cm to 9cm across at just 5.00, 10.00, 25.00, and 40.00 each. We will also offer a lot of 10 assorted, discounted down to 100.00 for the lot.

NATROALUNITE-2c- Okumanza Hot Spring, Gunma, Japan
Tiny white masses of this rare mineral, offered here as small powdery aggregates in a capsule. A member of the alunite group, the subject of one of the IMA's bizarre renaming proposals in 2010, eventually named in allusion to its double c-axis structural relationship to natroalunite rather than its original name of minamiite. Type locality material, only a few available @ 20.00 each.

PENKVILKSITE- Jubilee Pegmatite, Lovozero, Kola, Russia
Dull white, somewhat fibrous to platy masses of this rare species sparsely scattered in matrix, occasionally associated with finely crystallized radiating needles of raite and possibly other species. Type locality material obtained from one of the authors (Dr. Khomyakov) many years ago, offered as small fragments in a capsule @ 45.00; a few matrix specimens from 1.5cm to 3cm @ 100.00, 130.00 and 165.00 each.

QUARTZ (Japan Law Twin)- Andilamena, Alaotra-Mangoro, Madagascar
Excellent examples of Japan Law twinned quartz, these as flattened, V-shaped twins with definative striations and complex peripheral terminations. These are from the major find from twenty years ago at the locality. Only a few recently uncovered, all are sharp and average 3cm across @ 55.00 each.

QUARTZ variety CHRYSOPRASE- Malborough, Queensland, Australia
Vivid, lime-green chrsoprase as botroids and exposed seams about 1 cm thick, quality suitable for cutting if so desired! Originally acquired by Forrest Cureton many years ago, we just recently uncovered these in our warehouse. We have cleaned these with a high pressure water gun, removing most overburden, but most specimens tend to have a film of gritty matrix that begs some patient sandblasting that would render these into true gems for the mineral! Specimens range from about 4cm up to 7cm across, attractive and colorful, at just 15.00, 25.00 and 45.00 each. Nice!

RANKAMAITE etc.- Urubu Mine, Itinga, Minas Gerais, Brazil
This rare mineral occurs here as white to pale tan, somewhat fibrous, creamy aggregates richly intergrown in matrix, typically with pink elbaite, cassiterite, and quartz. Thin section work has also disclosed minute associations of simpsonite, thoreaulite and possibly other phases as well in these complex specimens! From a 2010 find and described in an American Mineralogist article a year later, we have a small lot of samples, ranging from about 1cm to nearly 3cm across @ 25.00, 40.00 and 65.00 each; don't miss these!

RANKINITE in LARNITE- Camphouse, Ardnamurchan, Argyll, Scotland
Greyish spurrite rock matrix shows small white masses of included rankinite, often intergrown with massive larnite as well. Classic locality material mentioned briwfly in a 1950 American Mineralogist article, all samples with at least one cut face, sizes ranging from 1cm to nearly 5cm across @ 25.00, 40.00, 65.00, 85.00 each

ROBINSONITE- Male Zelezne, Zilina, Slovakia
Metallic grey robinsonite is abundantly present in these rich, massive samples, comprised of metallic grey, somewhat fibrous robinsonite in matrix. A well-documented locality for this Pb-Sb-sulfide with a wide range of sizes and prices available, from 1.5cm to 5cm @ 20.00, 40.00, 65.00, and 90.00 each

SCHIZOLITE- Kedykverpakhk Mt., Lovozero, Kola, Russia
Found in 2015 at this locality, the mineral occurs as rich aggregates of tiny, coarse colorless prismatic crystals, typically embedded in aegirine nests at the edges of a white natrolite vein. Unlike the pinkish material first described from South Africa, this was the third occurrence for the species, confirmed by Russian mineralogists shortly after publication of IMA 2013-067 that was subsequently redefined in 2018. Specimens range from 2cm to 4cm across @ just 45.00, 75.00 and 100.00 each.

THORIKOSITE- Passa Limani, Lavrion, Attica, Greece
One of the more exotic "slag minerals" from this prolific area, here as minute, pale yellowis micro crystals sparsely scattered in ancient slag vugs, often with other uncommon species associated as well. Type locality material, specimens priced according to quality, not overall size, 1.5cm to nearly 3cm @ 45.00 and 65.00 each.

TOBERMOREITE ps @ WILKEITE- Crestmore Quarry, Riverside Co., California
Small white spherules and minute fibrous pods of tobermoreite occur here as pseudomorphs after "wilkeite" in pale blue calcite and occasionally admixed with jennite or other species. The material varies from lean to exceptionally rich and is priced accordingly, sizes from about 2cm to 7cm @ 12.50, 20.00, 35.00 and 50.00 each. One large and fairly rich sample about 13x9cm @ 125.00.

TOPAZ- Trumbull, Fairfield Co., Connecticut
An old specimen, ex-G. Fred Lincks, likely collected at Long Hill in Old Mine Park long before it became a forbidden collecting site, comprised of waxy fluorite (var: chlorophane, FL red), black magnesio-hornblende, andsmall rod-like crystals and masses of transparent topaz. The property is purported to be the first North American topaz locality, as well as the first mined tungsten deposit in North America. Not a pretty specimen, and mounted on styrofoam as was Linck's custom, but of great historic interest, overall size 7x4x4 cm @ 65.00.

URANOCIRCITE- Malacacheta, Minas Gerais, Brazil
Likely from the Sao Pedro Claim, this colorful and rather attractive specimen shows rich greenish yellow, parallel sheaves of uranocircite crystals scattered about brownish black rock matrix. Moderately hot, and showing good fluorescence as well, the specimen stands 3cm tall by 3.5cm wide at just 85.00. One only!

VANTHOFFITE- Berlepsch Mine, Neu-Stassfurt, Germany
A sodium magnesium sulfate, vanthoffite typically occurs as massive granular material. We have representative specimens, consisting of a few small translucent, nearly white colored grains of vanthoffite packed in a glass stoppered vial, some with possible halite or admixed loweite. Ex-Cureton samples, few available @ 35.00 each

COLLECTIONS
LANGBAN MINERALS- Langban, Filipstad, Varmland, Sweden
This classic locality has produced over 300 different species, with more than 70 type locality minerals within that number! We recently acquired the private collection of the late H. Rosenbroeck, a Dutch mineral dealer who travelled and collected extensively. These Langban specimens were acquired in 1975 and 1976, and have sat for more than 40 years unidentified but most being carefully numbered in his holdings awaiting further study. We admittedly have little time to work on this old Langban material, and we suspect there are many of the common species as well as potential rarities. Sizes range from about 3cm to 6cm across, and we offer lots of 12 Langban specimens for just 125.00 per lot. Buy two lots at the same time, and we will throw in a new copy of the full-color classic Langban book, a 79.00 value, at no extra charge!

GEMS
FACETED DIAMONDS- South Africa
We have a large inventory of both rough and faceted diamonds, and here we offer some interesting lots of small cut stones. Starting with small rounds of transparent, very pale brown hues that average about 1mm each and about 2pts each, we offer a set of five stones for just 30.00 per lot. Moving up to more fancy yellow colors, we have 25 point lots (average 8 to 10 larger stones) at just 95.00 per lot. If you want a half carat (50 points) of these fancy colors in these larger stones, they are here at just 175.00 per lot, 10-12 stones per lot; and finally, we can offer a full 1.50 carat lot, about 50 stones per lot, at just 450.00. These are the last of our faceted yellows!

PETROLOGY SAMPLES
PELE'S HAIR- Hilina Pali Road, Hawaii Co., Hawaii
Perhaps the most unusual of lava formations, these are extremely thin strands of basaltic glass fibers. They typically form as a result of the stretching of molten lava, often carried by wind, and it looks much like tiny strands of golden millerite by comparison. Named for the Hawaiian goddess of volcanoes, extremely brittle and sharp, we have samples richly supplied in capped, 5cm vials @ just 20.00 each. Collected in 1984 by the late Dutch mineral dealer H. Rozenbroek.

BOOKS
We are liquidating a huge mineralogical library, including many old issues and full sets of popular periodicals, with over 150 crates of both modern and older volumes of classic works, coffee table books, a few paleontology works etc. We will list a few interesting titles in each catalog, just to whet your appetite to expand your research library. See below!
Illustrated Guide to Rocks & Minerals by Michael O’Donoghue
This large format, hardcover book includes 192 pages, filled with 140 full color images of excellent specimens, offered here as a classy “coffee-table” book.

CATALOG 21906 – Volume XLVI, No.6

AGRELLITE- Kipawa Complex, Villedieu, Quebec, Canada
Excellent radiating and columnar aggregates of buff colored agrellite richly comprising matrix and showing fine, bright pinkish-red fluorescence under SW UV. Some specimens may show minor red eudialyte, catapleiite (FLgreen) and albite (FL-dull red) as well, making these unusual three-color fluorescent pieces. This newer lot is exJohn L. Baum collection (johnbaumite) of Franklin fame. Type locality material, sizes from 3cm to 8cm @ 10.00, 20.00, 35.00 and 50.00 each.

ALLANITE-(La)- Mochalin Log Valley, Potaniny Mts, Russia
This rare mineral occurs here as small (1mm-3mm) black aggregates in brownish bastnaesite-(La) matrix. Formula: Ca(La,Ce,Ca)Al2Fe2+Fe3+)(SiO4)(Si2O7)O(OH), IMA #2003-065, these from a second locality for the species. Material from this Kyshtym District in the southern Urals has been microprobe-confirmed as teh rarest of the allanites because of its La-domiance. Specimens available as small matrix samples from 3mm to 6mm across @ 55.00, 70.00 and 85.00 each. Only a few!

AUGITE- N of Las Canadas, Tenerife, Canary Islands
Old material collected by famous geologist/mineralogist E.W. Heinrich many years ago, these are sharp, wellformed, black single crystals removed from basalt just north of Las Canadas, near Caldera Junction, Tenerife. Excellent for the species and from an unusual locality, individual crystals range from about 1cm to 1.5cm tall at just 12.50 and 17.50 each. Try a selection of five different showing a variety of habits and sizes at just 45.00 per lot!

BAKHCHISARAITSEVITE- Iron Mine, Kovdor Massif, Kola, Russia
This rare phosphate mineral occurs as tiny, deep yellowish-grey platy aggregates lightly scattered in dolomite matrix, occasionally with minor magnesite as well. Formula: Na2Mg5[(PO4)]4(H2O)6.H2O. IMA approved in 1999, few specimens have reached the market of this type locality material. Sizes average about 2.5cm @ 150.00 each.

BRASSITE- Jachymov, Bohemia, Czech Republic
Representative specimens of brassite, as rich white powdery coatings on matrix, possibly intermixed or otherwise associated with pharmacolite and/or roesslerite. Type locality material, sizes from 1cm to 3.5cm @ 15.00, 25.00 and 40.00 each. Old stuff!

CALCITE- MaNieshan Mine, Hunagshi, Hubei, PR China
From the new find featured in the August, 2019 issue of Mineral News, these as stout, somewhat stunted scalenohedral crystals of brownish calcite completely comprising matrix. Rather attractive and an interesting habit for these iron-rich, included specimens, with individual crystals to 1.5cm and full coverage. Overall sizes from TNs to 5cm @ 10.00, 25.00 and 45.00; a few larger, aesthetic specimens (8cm to 10cm) @ 125.00 and 175.00 each.

CALCITE pseudo @ KUTNOHORITE- N'Chwaning II Mi, Kalahari, N. Cape, Rep So A
This interesting pseudomorph occurs as pale pinkish groups of somewhat rounded crystals and knobs of manganese-rich calcite comprising matrix, replacing needle-like crystals of kutnahorite. The pseudos are also nicely fluorescent (SW UV) red, and make interesting additions to a specialized pseudomorph or fluorescent collection. From a 2001 find at this prolific locality, specimens from about 3cm to nearly 6cm across @ just 15.00, 25.00 and 35.00 each.

CASSITERITE- Wheal Busy, Chancewater, Cornwall, England
Collected from the area surrounding the Black Dog Shaft some years ago, cassiterite occurs here as tiny black micro crystals lightly scattered on a greyish breccia matrix. The deposit was worked for copper in the early 1700's and remained sporadically active until the early 1900s. An excellent, older locality (aka Graet Wheal Busy) yielding specimens with some micro potential, overall sizes from about 2.5cm to 6cm across @ just 5.00, 15.00, and 30.00 each. A bargain!

CLINOCLASE- Majuba Hill, Pershing Co., Nevada
Dark greenish blue, higly lustrous micro crystals and aggregates of clinoclase richly scattered over rock matrix. Classic locality material collected many years ago, matrix sizes from about 2cm to nearly 8cm across @ 8.00, 12.50, 20.00, 35.00, 50.00 and 75.00 each. A few higher - see images on our website in the Photo Gallery section on the website.

DAUBREELITE- Norton County Meteorite, Kansas
This rare species occurs here as microscopic inclusions in the Norton County meteorite, a rare Aubrite type achondrite that fell on February 18, 1948. These are individually microprobed by Bart Cannon in 1987, here as small (4mm) probe mounts, most with a single grain of material. Only a few available from this historic find @ just 100.00 each. We also have a pair of mounts accompanied by full color photographs with tissue overlays that pinpoint the typical association of kamacite, troilite and/or alabandite at 150.00 each. List alternates!

DOVYRENITE- Yoko-Dovrenskiy Massif, Transbaikal, Russia
This rare species occurs as minute, pale pinkish purple masses (not grey as claimed elsewhere - caveat emptor!) very sparsely scattered in matrix. Formula: Ca6Zr(Si2O7)2(OH)4; IMA # 2007-002. We have several small matrix samples, all type locality, of course, each about 3mm tall and requiring some magnification (30x) to discern the species @ 145.00 each.

FLUORNATROMICROLITE- Bennett Quarry, Buckfield, Maine
This relatively rare species was originally described from Brazil, even though found here at an earlier date. Unlike the type locality, these samples are an odd yellowish color, occurring as minute, flattened aggregates sparsely scattered in trilithionite, occasionally with minor cassiterite as well. Matrix sizes range from 2.5cm to 5cm @ 15.00, 30.00 and 45.00 each.

GALENA (Stressed Structure)- Huanzala Mine, Ancash, Peru
This Peruvian locality is best known for its fluorites, but we recently located several flats of massive galena collected in the early 1970s from the locality. The massive material is unusual because it does not show galena's distinct cleavage very well, the result of trace elemental impurities that affect the prevalence and degree of cleavage in these "structurally stressed" specimens. Our EDS work indicates trace silver is the culprit. Specimens
range from 2.5 to 5cm across @ just 5.00, 7.50 and 12.50 each. We can also supply a lot of 10 assorted at a greatly discounted price of just 50.00 per lot!

GARTRELLITE- Black Pine Mine, Granite Co., Montana
Bright yellow-green crusty masses and small botryoids of EDS and XRD-confirmed gartrellite scattered on quartz matrix, occasionally with micro, deep red cuprite sparsely associated. A rare combination and discovered by us (see Mineral News - Vol. 28 # 6, 2012), identification by micro-analytical techniques is needed to differentiate the species from several other, similar-appearing species at the locality. The mineral is rare here, and there are few specimens, some of the better ones offering the excellent micro associations as well! Sizes range from about 1.5cm to nearly 4cm @ 15.00, 25.00, 40.00 and 65.00 each, all with copies of our EDS work, and priced by overall quality, not size. (NOTE: Type locality material, as well as a few other localities, are in stock - inquire!)

GOLD- Riddle Creek Mine, Victoria, Australia
Small samples of well-crystallized native gold acquired over 20 years ago from a small Ballarat museum, each bright crystalline group presented in a black felt-lined round case. These obscure locality gold specimens range from about 7 mm to 10 mm and are priced at 45.00, 65.00 and 85.00 each. Aesthetics count!

GROSSULAR- Nightingale District, Pershing Co., Nevada
From a remarkable find about 10 years ago, wonderful crystal groups of grossular garnet richly comprising matrix! These show excellent reddish brown color with well developed crystals and high luster, perhaps the finest garnets ever found in the state! Our analytical work shows these to be a slightly iron-rich grossular that approaches andradite, but clearly Al-dominant nonetheless. These attractive specimens range from about 2.5cm to nearly 8cm across, priced at just 10.00, 15.00, 25.00, 40.00, 60.00 and 85.00 each, with a few to 100.00. Don't miss these, noted in the 2009 Mineralogical Record's Springfield Show report!!!

HEMIMORPHITE (botryoidal)- 79 Mine, nr. Hayden, Gila Co., Arizona
An uncommon habit for hemimorphite, these 79 Mine samples are pale blue botryoids forming exposed semas and largely comprising matrix. Often mistaken for smithsonite from other localities, these specimens were first acquired in 1968 and therefore preceeded the more well-known material brought out from the third level in the 1970s. Mostly smaller, rich specimens, sizes from about 2cm to 3.5cm @ just 7.50, 10.00 and 15.00 each.HSIANGHUALITE- Xianghualing Mine, Linwu, Hunan, PR China White vitreous masses and tiny aggregates of this rare species scattered in matrix, a Ca-Li-Be silicate-fluoride first desccribed in 1958. One of the rarest of zeolite minerals the samples typically display non-descript granular forms with occasional dodecahedral faces evident. Type locality material (and still only found in the Xianghualing ore field), each sample accompanied by XRD data and an SEM image, sizes average 1cm just 95.00 each, with confirming analytics!

HUMBERSTONITE- Oficina Alemania, Antofagasta, Chile

Excellent tabular to unusual, elongated hemimorphic clusters of transparent to white micro alunite crystals nicely scattered over dense, white kaolinite matrix. Fine older material from the type locality area for the species, some with good micro potential as well. matrix sizes from about 2.5cm to 6cm @ just 10.00, 15.00 and 25.00 each.

AMBLYGONITE- Mt. Rubellite Quarry, Hebron, Maine
Solid, off-white masses of amblygonite comprising matrix, collected in the late 1960s and XRD-confirmed. From one of the few confirmed Maine localities for the species, as much material labeled amblygonite has proved to be montebrasite instead. Specimens range from about 2.5cm to nearly 8cm across at just 10.00, 15.00, 30.00 and 45.00 each.

AMBRINOITE- Signols, Oulx, Val Susa, Torino, Italy
This relative new and rare occurs as brilliant red, micro elongated and flattened aggregates sparsely scattered on white anhydrite matrix, some with minor gypsum, albite or yellow orpiment. From the Cumbe Surde quarry (type locality), a weird hydrated sulfosalt. Formula: [K,(NH4)]2(As,Sb)6(Sb,As)2S13*H2O, triclinic, IMA # 2009-071. Originally found in 1998 and the last of our stock, this is type locality material offered as specimens from about 2cm to 3cm across, all requring magnification and provided with arrows, @ just 65.00 and 85.00 each, depending on quality and size.

ANGLESITE- Monteponi Mine, Iglesias, Sardinia, Italy
An old classic specimen showing about a half dozen anglesite crystals to 1 cm randomly scattered about a massive galena matrix. Most of the somewhat flattened and nicely striated anglesites are transparent on an otherwise rather ugly, grayish black substrate. The piece measures about 8x4cm and is rather heavy, a good representative specimen for this old locality at 350.00. One only!

ARAVAITE with ARIEGILATITE- Hatrurum Basin, Negev, Israel
Two very NEW SPECIES are found together in these small polished sections, the aravaite - Ba2Ca18(SiO4)6(PO4)3(CO3)F3O (IMA 2018-078) - occurring as white crystalline aggregates in massive spurrite, associated with intimately associated colorless, trigonal ariegilatite - BaCa12(SiO4)4(PO4)2F2O - IMA 2016-100. Each 2cm polished sample is accompanied by three SEM images that identify and pinpoint the species in question, with full electron microprobe results for the aravaite. Only a few superbly documented specimens on hand @ 375.00 each.

BARITE- 975' level, Meikle Mine, Elko Co., Nevada
Undoubtably the finest barite specimen occurrence ever found in the U.S., these Meikle barites were collected underground in 1997 in the 3525 stope (20450N, 8450E). They are nicely transparent, pale yellow in color, as excellent, tabular single crystals and groups, all quite attractive and of competition quality. Neatly mounted in standard TN boxes, these choice specimens are offered at 85.00, 125.00, 150.00 and 175.00 each, depending on overall aesthetics and quality. For those interested in larger specimens from other areas in the mine, we have groups to 20cm across @ 3500.00. Please inquire!

BARRERITE- Kuiu Island, Alexander Archipelago, Alaska
Platy, white to slightly pinkish spear-shaped orthorhombic crystals and aggregates of the uncommon zeolite barrerite, scattered on matrix, some associated with minor quartz, heulandite and possibly other zeolites. This material is visually similar to stilbite, and microprobe and X-ray work on the material has shown it to be the rare zeolite barrerite, discovered here in 1984. These specimens were originally collected by the former claim holder, Istvan Toth, the major source of all Alaskan barrerite for many years, the locality often attributed to Rocky Pass. Since the borough designations in Alaska are changing, we no longer use "Sitka" as the borough in our labels. Sizes from about 3cm to 8cm across, priced lower than our last offering in 1998, at just @ 15.00, 25.00, 40.00 and 65.00 each, based on quality. Moderately attractive and likely the finest barrerite occurrence in the world!

BASTNAESITE-(Ce) in FLUORITE- Red Cloud Mine, Lincoln Co., New Mexico
Small masses of micro, tabular tan to brown colored bastnaesite-(Ce), scattered among beige, corroded barite filling small pods and seams in a massive, fluorite-rich matrix. Old material collected more than 25 years ago, requiring some magnification to pick out the sparsely scattered bastnaesite-(Ce) crystals from the surrounding matrix. Specimens range from about 1cm to 3cm @ just 5.00, 10.00 and 15.00 each. Try a special lot of 10 small specimens @ only 40.00 per lot.

BELOMARINAITE & METATHENARDITE- Arsenatnaya Fumerole, Tolbachik, Russia
Russian scientists continue to work on these weird Kamchatka species from the fumeroles of the Tolbachik volcano, this one forming extraordinary, flattened skeletal aggregates of clear to white belomarinaite, typically made cloudy on most samples by included metathenardite (IMA 2015-102). Both species are new for the locality (see our image on Mindat.org), with the new species formula noted as KNa(SO4) - trigonal - IMA 2017-69a, a new member of the aphthitalite group from the second world locality for the species. Specimens are very thin, tabular and range from about 1.5cm to 3cm across @ 150.00, 175.00 and 225.00 for the best ones, depending on size and form, and quite large for a new species! Samples carefully mounted in a plastic box for protection.

CALCITE variety "Cave Calcite"- near Ash Fork, Yavapai Co., Arizona
Attractive, "cave formation" calcite, showing tubular stalactitic masses, botryoids and similar weird forms attractively displayed in these older specimens. Acquired circa 1967, these white to tan oddities may be from the caves in adjacent Coconino County, with Ash Fork being the nearest settlement. The specimens are reminiscent of the "flos ferri" habit seen in some aragonite formations, and they display well. Overall sizes from 5cm to 10cm across @ 20.00 and 50.00 each. Only a few on hand!

CHENEVIXITE- Cu Stope, Majuba Hill, Pershing Co., Nevada
Pistachio green, richly scattered chenevixite on rhyolitic breccia matrix, surprisingly well scattered on quartz crystals and occasionally associated with other secondary minerals from this prolific locality.

CREEDITE - Dachang Mine, Qunlong, Guizhou, PR China
An excellent group of lavender (!!!) creedite crystals with little matrix, here as spear-shaped, elongated, amethystine crystals to 2cm long, in a riotous group of many gemmy, small ones associated with and adding to the overall aesthetics of the piece. A choice specimen, one only, overall size about 5x4cm @ just 250.00. Nice!

DJURLEITE pseudo @ FOSSIL WOOD- Scholle District, Torrance Co., New Mexico
An unusual and previosuly unreported occurrence of djurleite replacing fossil wood, collected about 25 years ago and only recently surfaced here. This unnamed prospect (coordinates provided with original label) suggests additioanl copper minerals were likely encountered here.

FERVANITE etc.- Jo Dandy Mine, Montrose Co., Colorado
Think bands and circular pods of yellowish brown , somewhat granular-appearing fervanite scattered in matrix, locally associated with goethite, montroseite, gypsum and possibly other minor species such as hewettite as well. An interesting vanadium-rich mineral from the Hummer portal, specimens range in size from about 3cm to 7cm across @ just 12.50, 20.00 and 40.00 each.

FLUORITE on QUARTZ- Huanggangliang Mine, Inner Mongolia, PR China
Known for its superb fluorites with weird quartz combinations, this prolific mine has produced several more outstanding association specimens of these two species. Recently obtained by our agent on site, we offer an excellent specimen showing a pair of diverging translucent quartz crystals, both terminated, respectively 8cm and 9cm long, joined at an angle of about 60 degrees, nicely covered with over a dozen, isolated, transparent fluorite crystals to 1.5cm that are water-clear, and each exhibiting complex and highly modified cubo-octahedral forms! Micro galena and flattened lollingite crystals are evident under the 'scope, as is a tiny 2mm crystal group of scheelite at one edge of the piece, it being brilliantly fluorescent, of course. Overall specimen length is about 14cm across, a fine cabinet specimen, only only @ 575.00.

GAGARINITE-(Y)- Verkhnee Espe Massif, Tarbagatai, Kazakhstan
Pinkish red or somewhat orange colored, coarsely prismatic aggregates of this rare species scattered in quartz pegmatite matrix. Type locality material, named after Yuri Gagarin, the first man in space. There are a numberof obscure smears, pods and masses of other phases associated with these specimens, calling for further study in the lab, no doubt! Type locality material, specimens from 2.5cm up to 5cm across @ 50.00, 85.00 and 125.00.

HALITE- Rhodes Salt Marsh, Esmeralda Co., Nevada
Clusters of translucent white halite crystals showing good cubic forms, intergrown into attractive groups without matrix. A few specimens have individual crystals as large as 1.5cm wide, all quite attractive.

Only four columnar specimens available showing typical tourmaline morphology, the pseudomorphs are typically 5cm to 6cm tall @ 65.00 each. Strange!

MACKAYITE- Mina Candelaria, Moctezuma, Sonora, Mexico
Small masses and smears of dull yellowish green to brownish green mackayite lightly scattered on tough quartz matrix. Reasonably ugly stuff, but the potential for finding other rarities upon trimming makes it all worthwhile. The locality has produced cliffordite, poughite, schmitterite and even minor gold, these specimens ranging from 3.5cm to 8cm across @ just 20.00, 35.00 and 65.00 each.

As featured in the June, 2019 issue of Mineral News, we have a couple of remarkable oxyplumboromeite pseudomorphs after bournonite, the first ever reported! The specimens have been confirmed by both EDS and PXRD. The mineral occurs as deep yellow, prismatic replacements of columnar, orthorhombic single crystals,
the most complete and perfect crystal is 4cm tall and sits on a matrix of drusy quartz (pictured in the aforementioned article and in Mindat.org as well), the sample offered at 1750.00. A larger 8cm tall specimen, also illustrated in the article, is singly terminated and shows sharp prism faces but is largely damaged on the back of the piece, the only other sample available from this unique find, offered @ 1500.00. Great rarities!

PLUMBOGUMMITE w/ MIMETITE etc.- San Rafael Mine, Nye Co., Nevada
An exceptionally large specimen comprised of many hundreds (thousands?) of tiny WHITE hexagonal mimetite crystals richly scattered on both sides of this somewhat flattened matrix piece, accompanied by a rich scattering of greenish plumbogummite on one large face, less so on the other, along with light coverage of micro, transparent to white tabular wulfenite crystals as well! Highly unusual colors for both the mimetite and wulfenite, noted in our 2010 Rocks and Minerals article (Vol. 85, 512-524) on the locality. An interesting association specimen with virtually unlimited micro potential (if you dare to break it up), overall size about 18cm x 18cm @ 175.00. One only in this large cabinet size!

Roweite occurs here as euhedral, pale orange-brown, orthorhombic, spear-shaped, transparent to translucent crystals to 1.5cm on matrix, most associated with white to colorless spears of the rare mineral olshanskyite, making for excellent association specimens of two rare species! Earlier Chinese material was generally in opaque stacked platy aggregates, this new find quite superb by comparison, and also significantly less costly! Specimens range from fine TNs to nearly 3.5cm across, competitively priced at just95.00, 145.00 and 200.00 each, depending on quality and crystal size. Confirmed by EDS and PXRD, we believe these are the BEST of species, being both attractive and in well-formed crystals!

RUTILE var: ILMENORUTILE- Haverstad, IIveland, Aust-Agder, Norway
Old material from a classic locality collected in late 1937, these from a noted European geological museum. The ilmenorutile, formerly considered a species and now relegated to a nibian-rich rutile, occurs as greyish black masses comprising or richly scattered in minor matrix, specimen sizes ranging from about 1cm to nearly 3cm across @ 15.00, 25.00 and 45.00 each, accompanied by copies of the museum labels

JAROSITE- Various Localities, Worldwide
Perhaps the easiest way to build a diverse collection of a specific mineral species, we occasionally offer small lots of a single mineral from many different localities. This time, it is jarosite, occurring as amber to dark brown trigonal micro crystals scattered on matrix, offered as a lot of six different localities (including the type), with specimens ranging from 2.5cm to 5cm across, some with older labels and a wide range of associations, many
with trimming and micro potential as well. Each lot of six is just 75.00, bargain priced!

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, too, at just 10.00 per 5cm vial. The last of this material!

GEM
QUARTZ variety PRASIOLITE- Brazil
One of the more unusual colors in quartz gemstones, prasiolite is a delicate, pale green color, these quite transparent and pleasing. Most Brazilian material has been heat treated, and we have only a few stones available, all in good quality faceted ovals in varying sizes from about 12x8 mm up to 22x10 mm, attractively priced at just 15.00, 25.00 and 40.00 each. In addition, we have a number of larger, free-form faceted stones in exotic shaps and sizes, so please inquire! Very inexpensive for this quality!

FLUORAPATITE var: MANGANAPATITE- Melrose Pegmatite, Stoneham, Maine
From a rather obscure pegmatite on Sugarloaf Mountain in Oxford County, These are typical coarsley crystalline samples of feldspar and muscovite, with small, dark greenish Mn-apatite scattered about, the mineral best obsertved by its luorescent response (orange in SW UV and less so in LW UV). Some samples will show micro almandine and often tiny areas of meta-autunite (also observed via SW UV). Small hand specimesn averaging about 6cm across @ just 25.00 each.

GALENA (Spinel Law Twin)- Buick Mine, Iron Co.,. Missouri
A rare twin for galena, these spinel-law twins present as flattened, tabluar crystals to 2cm across (!!), appearing as thin plates, pseudohexagonal in aspect, similar to Goldschmidt's figure No. 68. Very weird and rarely seen in galena, we have only a few very well-formed thumbnails, these collected underground almost 25 years ago from the 17143 pillar, (150681N-74462E), most with minor sphalerite evident. Perhaps never to be seen again, offered at 275.00 and 350.00 each. List alternates!

GENTHELVITE- Cerro Blanco Tanti, Cordoba, Argentina
An unusual occurrence of pale blue, glassy genthelvite masses and tetragonal aggregates scattered in hematite/chalcocite ore matrix, some with oligoclase and possibly other phases.

Excellent quality for this rarity!

PAULSCHERRERITE- Ruggles Mine, Grafton County, New Hampshire
This uranium-bearing mineral is a major constituent of 'gummite' at both Palermo and Ruggles. These specimens were collected around 1966, and occur as orange waxy masses associated with black uraninite and other phases in a pegmatite matrix. Originally described (as "gummite") by Frondel in 1956 and later studied by Gene Foord, et al., and found to have a uranyl-oxide hydroxyl-hydrate composition (then called "Mineral A"). Subsequent chemical, Raman and XRD study in 2011 confirmed that largely dehydrated schoepite, the mineral paulscherrerite, was a major constituent (with metaschoepite) of the orange-yellow "gummite" at this locality. In sizes from 1.5 cm to 6 cm, @ 20.00, 35.00, 50.00, and 85.00 each. A few monsters from Ruggles, 10 cm to 24 cm long @ 300.00 to 600.00 on hand - please inquire.

Old tiem stuff, relativeluy inexpensive, matrix sizes from about 4cm to 7cm across @ 10.00, 20.00, and 35.00 each, a few larger to 10cm @ 75.00.

VESUVIANITE- Val Chedul, Trentino Alto Adige, Italy
An old specimen, ex-A.E. Seaman Mineral Museum via L.L. Hubbard (1849-1933), labelled simply as "Chedul Glacier". Depending on when it was collected, the area was once part of the Austro-Hungarian Empire, subsequently Tyrol, Austria, now part of Italy, with both German and Italian speaking enclaves. The specimen presents a crudely crystallized pale green vesuvianite aggregate, with a few obvious crystal faces evident with no discernable matrix, but overall an interesting reference piece for the area. The Museum label accompanies this 9x6cm specimen @ just 55.00. 

WULFENITE- Cuchillo Parado, Chihuahua, Mexico
We found a jumbled flat of this material in the warehouse with our Hoxie Street (Bronx, NY) label (circa 1974) and a David New tag, suggesting these were early 1970s vintage specimens. The wulfenite from here is orange to orange-brown, thickly tabular, occasionally with minor calcite rhombs. While there are no killers in the lot, they are representative specimens from a lesser-known wulfenite producer in Mexico, perhaps 45 to 50 years ago. We have hand-selected a few moderately attractive samples from the lot, sizes range from 3cm to 5cm, priced according to quality at just 15.00, 25.00 and 35.00 each. Neat old stuff!

COLLECTIONS
WARDS NATURAL SCIENCE SPECIMENS
We recently uncovered a small lot of old Wards Natural Science mineral specimens, each presented in a 7x7cm cardboard tray, and each individually labeled with a 7x 2.5cm Wards display label. Each label offers the mineral name and locality, as well as the Dana number used by Wards as presented in the 1892 edition of Dana's System of Mineralogy (6th edition). While there are no rarities here, the minerals, trays and labels are interesting historical artifacts, estimated to be about 100 years old since they were assembled. We offer a selection of six (6) different trayed specimens @ just 75.00 per lot. Limited availability!

GEM
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!
PETROLOGY SAMPLE
VOLCANIC BOMB- Mt. Leura, Victoria, Australia
An oddity for your collection: a dark scoria "volcanic bomb" from this uncommon volcanic locality, originally in the collection of Howard Blye (b.1890) of New York City and accompanied by his label. We know little of the man, other than he was a member of the New York Mineralogical Club in the 1950s and 1960s, prior to his death in 1978. The scoria from Mount Leura was notable for prolific, high temperature xenoliths, here obscured by surface weathering in this large, flattened egg-shaped specimen that measures 10x7x5cm, offered at just 75.00. One only!

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!

Micro black cubes and aggregates of murdochite richly scattered on limonitic matrix, occasionally with other secondary copper minerals. Old material, ex-F. Mecke Collection, sizes average about 5cm @ 40.00 each. Nice!

NAKAURIITE- Nakauri Mine, Shinshiro, Aichi Prefecture, Japan
Obviously from the type locality, moderate coverage of this compound copper mineral occurs as pale blue to bluish green thin crusts on serpentine rock. Moderately attractive material, somewhat lean but quite representative for nakauriite, in sizes from 1.5cm to 5cm @ 15.00, 25.00, 40.00 and 55.00 based on size and coverage.

PARABERZELIITE (IMA 2018-001)- Arsenatnaya Fumerole, Kamchatka, Russia
The description and approval of new minerals from the famous Tolbachik Volcano continue, and this one is tiny but quite attractive as glassy, pale sherry-colored monoclinic crystals and aggregates carefully mounted on adhesive disks. Formula: NaCa2Mg2(AsO4)3, monoclinic, IMA #2018-001, a new member of the alluaudite group and dimorph of berzeliite. Magnification will be needed to appreciate these delicately hued micros, and we have only a few of them available @ 165.00 each. Type locality, of course!

PREHENITE- Lower New St., Paterson, Passaic Co. New Jersey
A rather large, lenticular-shaped vug in Watchung basalt that extends over 18 cm in length (!!), exposing a rich, pale green botryoidal mass of prehenite that completely fills the opened pillow matrix. The locality was worked up until the mid-1930s, and this specimen is ex-Dr. G. Sensel, acquired in June, 1966. A handsome specmen, overall size about 22x7cm @ 125.00. One only.

PYRARGYRITE, POLYBASITE etc.- Mina Sirena, Guanajuato, Mexico
Selected from a large lot, we have a good number of grayish metallic pyrargyrite crystals and convoluted knobby aggregates comprising matrix, many showing interesting habits and occasionally associated with native silver or other silver minerals. Analytically confirmed, small but neat TN's that average 1cm to 1.5cm @ 25.00, 35.00 and 45.00 each, depending on quality.

PYROMORPHITE- Bunker Hill Mi, Kellogg, Shoshone Co., Idaho
This famous property operated sporadically from 1886 to 1994, producing a wide range of minerals and various colors of pyromorphite along the way. These samples were acquired circa 1960, long before the modern heyday of collectible specimens came to market. The pyromorphites are in typical, barrel shaped, elongated crystals to 3mm sacattered on rusty quartz/rock matrix, the crystal color a pale greyish green reminiscent of those supplied by the late Ted Morley in the 1950s-1960s when the property was worked by the Bunker Hill Co., prior to the Gulf Resources and Chemical Co. takeover. Decent coverage on these generally small specimens, matirx sizes from about 2.5cm to 4.5cm @ 5.00, 10.00 and 20.00 each, or as smaller samples in lots of five for micromounting @ 12.00 per lot of five. Old stuff!

QUARTZ- Little Devil's Workshop, Gaston Co., North Carolina
An old specimen from the Benjamin Ackerman Collection, originally labeled as "Devil's Works Iron Mine", presented here as a large but crude clear quartz crystal that measures about 12cm long by 6cm across, showing several sharp faces but with multiple areas of abrasion and a few areas of Mn/Fe oxide staining evident as well. The locality is now known as the Mountain Ore Bank Mine. The crystal weighs a little under 2 lbs and is no beauty, but its relatively large size and off-beat locality provide much interest as a result. Size is 12x6x7cm @ 55.00; one only!

QUARTZ with inclusions- Chaiyaphum, Kaset Sombum District, Thailand
An unusual specimen comprised of three major quartz crystals to 4cm intergrown to form a complex stacked group of transparent, weirdly modified habits, admittedly with detachment at the bottom and some damage on some of the complex terminations. Most interesting, however, is under the 'scope which discloses pointed spear-shaped needles of quartz(?) pointing into the core of the specimen, as well as numerous hollow areas, floaters and growth chevrons evident as well at 10x or better. There is mild limonitic staining within the group, also enhancing its appearance at modest magnifications, highlighting some of the staggered growth patterns and voids within the sample. An uncommon locality piece, originally obtained nearly 30 years ago from Mountain Minerals International and residing in the private collection of Scott Williams. Both labels accompany this 5.5x4x3.5cm group @ 65.00. One only!

RHABDOBORITE-(V) IMA #2017-108- Arsenatnaya Fumerole, Kamchatka, Russia
A new and extremely complex mineral from the second scoria cone of the Tolbachik Volcano, here as tiny groups of yellow to pale golden, acicular crystals typically perched on glassy micros of anhydrite, occasioaally with elongated coppery ludwigite, orange berzeliite and possibly other phases. Formula: Mg12(V5+, Mo6+, W6+)1.5O6{[BO3]6-x[(P,As)O4]xF2-x}(x<1) - hexagonal, IMA # 2017-108 and isostructural with the W-dominant new mineral described below. Rich specimens, with excellent micro potential as well, specimen sizes available are either as TNs @ 200.00 each or a few larger, richer specmens to 4cm @ 325.00 each. List alternates!

RHABDOBORITE-(W) IMA #2017-109- Arsenatnaya Fumerole, Kamchatka, Russia
This new species is the tungsten-analog of rhabdoborite-(V) (see above), occurring here as pale beige acicular crystal groups and aggregates scattered on transparent anhydrite micros with berzeliite, ludwigite and possibly other phases. Formula:Mg12(W6+,V5+)1.5O6[{BO3]6-x[P,As)O4xF2-x}(x,1), hexagonal, IMA # 2017-109. Type locality, of course, with good micro potential as well. Size from TNs @ 175.00 to 4cm @ 300.00 each. List alternates!

STILBITE- Paterson, Passaic Co., New Jersey
From several old collections, we have a modest accumulation of typical New Jersey stilbite specimens from this famous locality. The crystals range from 5mm to 2.5cm, and typical zeolite associations may be present. Overall specimen sizes range from about 4cm to 8cm across, and all show good coverage @ just 15.00, 30.00 and 45.00 each.

TOPAZ- nr. Teofilo Otoni, Minas Gerais, Brazil
This is a MONSTER crystal of water-clear topaz, weighing about 6.5 pounds(!!!) and measuring about 12x12x7cm tall!! It was purchased on March 6, 1964 in Teofilo Otoni for gem material, and the specimen shows several excellent terminal faces, a strange "V-shaped" etched face, and a basal pinacoid cleavage, as well as the typical conchoidal fracture where detached from matrix. Expect some bruising on this HUGE gem crystal, a giant specimen, certainly the largets clear topaz we have ever had, offered at 2800.00.

TRIPHYLITE- Pribyslavice, Czech Republic
Massive brownish triphylite, here comprising much of the specimens, also associated with quartz, mica, feldspar and occasionally bluish vivianite, graftonite etc.. in these otherwise unattractive locality specimens collected in 1974. Sizes average about 5cm to 6cm across @ 25.00 and 30.00 each.

TSUMEBITE- Hard Luck Claims, San Bernadino Co. California
This interesting locality, commonly called the Blue Bell Mine, has produced more than 85 different species, many in good micro crystals. We have a small selection of tsumebite specimens from here, most as pleasing, glassy green micro aggregates scattered on matrix, typically with cerussite and a wide range of other associated species. Specimens range from about 2.5cm to 5cm across and are priced according to quality @ 10.00, 20.00 and 35.00 each. Cool stuff!

TUNELLITE- Jenifer Mine, Boron, Kern Co., California
Translucent tabular crystals of pearly tunellite, some with minor ulexite matrix from this famous locality. Very old material for this uncommon strontium-borate mineral, known only from California and Turkey.

URANOPHANE on MONTROSEITE etc.- Opera Box Mine, Montrose Co., Colorado
Tiny, bright yellow balls of uranophane comprised of minute, radiating needles lightly scattered and perched on nearly black montroseite matrix, typically with other species such as rauvite, paramontroseite, coffinite and others. From the first locality outside of Utah to produce magnesiopascoite as well, material from this small operation was featured in our February, 2015 article in Mineral News. Only a few samples on hand, 2cm @ 15.00; 3.5-4cm @ 30.00; a few larger to 7cm @ 55.00 each. Most will have modest micro potential as well.

VANADINITE with CALCITE- San Carlos Mine, Manuel Benavides, Mexico
Old classic material from this Chihuahua locality, these acquired more than 50 years ago in the mid-1960's, showing excellent, bright orange, glassy micro crystals of vanadinite to 3mm tall, very richly scattered over transparent, colorless rhombs of calcite on rock matrix. 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!

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.

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!

CATALOG 21802 – Volume XLV, No.2

ALBITE on ORTHOCLASE (Twins!)- Organ Mts., Dona Ana Co., New Mexico
An small lot of very unusual feldspar specimens, ex-Scott Williams from when he operated out of Oberlin, Kansas. Each specimen has small, white albite crystals (variety pericline) perched on well-crystallized, buff colored orthoclase that shows good Baveno twinning. The pieces are fairly attractive and average about 5cm tall @ 55.00. One excellent sample a little over 6cm showing a rare Manebach twinned orthoclase as well is on hand at 85.00, all likely from the Rock Springs Canyon locality. List alternates!

ALUMOEDTOLLITE (IMA #2017-020)- Arsenatnaya Fumerole, Tolbachik Vol. Russia
Perhaps one of the rarest copper minerals from this prolific Kamchatka Volcano, this NEW SPECIES occurs as extremely tiny, single dark splintered crystals mounted on a 1cm adhesive disk, requiring 30x or more to observe. Formula: K2NaCu5AlO2(AsO4)4, triclinic, IMA # 2017-020. Author's material from the type locality, the mineral is an analogue of edtollite (which see in this list) with Al prevailing among trivalent cations with Al>Fe3+. Only a few on hand @ 195.00 each.

ANALCIME with STILBITE- Skookumchuck Dam, Thurston Co., Washington
Translucent to transparent trapezeohedra of analcime from 4mm to 7mm across are well-scattered on Eocene basalt, typically with small, bladed stilbite crystals and occasionally with lesser thomsonite or other zeolite phases. Old material from one of the late Rudy Tschernich's finds in the 1970s near Bucoda. Specimens range from about 3.5cm to 5cm across @ just 10.00, 17.50 and 25.00, priced according to quality, not size.

ANATOLYITE (IMA #2016-040)- Arsenatnaya Fumerole, Tolbachik Vol. Russia
New species continue to be described from the second scoria cone of the Northern breakthrough of this famous Kamchatka fissure eruption. Anatolyite occurs as tiny clusters of slightly pinkish crystals with white potassic feldspar, here as minute samples under 1mm mounted on 1cm adhesive disks. Formula:
Na6(Ca,Na)(Mg,Fe3+)3Al(AsO4)6, trigonal, IMA #2016-040. Type locality and author's material, will require 15x or more to appreciate their delicate color, named for Russian mathematician and crystallographer Anatoly Kapitonovich Boldyrev (1883-1946) of the Leningrad Mining Institute. Only a few tiny samples available @ 165.00 each. List alternates!

ANDRADITE- Coatsgate Quarry, nr. Moffat, Scotland
From a find in 1994, we have a single specimen of highly adamantine garnet in rich, micro crystals scattered across one surface. Under the scope, the garnet shows is transparent and colorless at the surface, with greenish-brown cores that give the sample its color. Rather interesting and unusual, only one specimen on hand, about 5x3cm @ 45.00.

ANDRADITE variety MELANITE- 1 mile S of Gem Mine, San Benito Co. California
From old Cureton holdings, a small lot of black andradite crystals forming densely intergrown druses nicely covering matrix, many with micro potential for this Ti-rich andradite garnet. Specimens show good luster and are reasonably attractive, specimens from 3cm to 5cm across @ 15.00, 30.00 and 55.00 each. Nice!

ARAGONITE (Blue!)- Wenshan Mine, Yunnan Province, PR China
Attractive, pale blue botryoids and stalactitic aggregates of aragonite comprising matrix, these showing excellent color for the mineral. This area was also the producer of the blue, botryoidal hemimorphite specimens that resembled classic Kelly smithsonite seen some years ago. Very pleasing color and surprisingly inexpensive, specimens average 4cm across at just 10.00 and 15.00 each, depending on degree of crystallization!

BITIKLEITE-SnAl- Lakargi Mt., Kabardino-Balkaria, Russia
This exceptioonally rare garnet group species is a NEW GARNET structure mineral, but lacking silica! It occurs as microscopic yellow aggregates in ~1cm polished sections of cuspidine and etttringite with other phases. Formula: Ca3SbSnAl3O12, IMA #2009-052. The sample is mounted in an epoxy probe mount and is
accompanied by a color macro photograph as well as three SEM images pinpointing and identifying all associations (up to 8 have been found already!), as well as a full quantitative chemical analysis! Only one available @ 395.00 each!

BOULANGERITE with QUARTZ- Pribram, Bohemia, Czech Republic
An interesting specimen comprised of numerous small quartz crystal points forming a convoluted bed on thin matrix, invested in several spots by tiny, dark grey, micro fibrous boulangerite tucked into nooks and crannies among the quartz. The piece is ex-Czech National Museum and is accompanied by their label. A moderately attractive specimen with an area of apparent casts after an unknown mineral, overall size about 10x8cm @ 80.00. One only!

CHALCOPYRITE on SPHALERITE- Baxter Springs, Cherokee Co., Kansas
An old lot of material originally acquired from Tri-State dealer Boodle Lane in 1957, these specimens show small, brightly metallic, wedge-shaped brassy crystals of chalcopyrite well-scattered over rich sphalerite crystals and masses comprising matrix. Tilting the specimens back and forth results in flashes of bright reflection from variably oriented chalcopyrite crystals, but often reveals deep red-brown coloration of the brilliant sphalerite underlaying them. Specimen sizes from about 4cm to 8cm across @ just 10.00, 20.00 and 35.00 each. Great old stuff!

CRANDALLITE- Clay Canyon, nr. Fairfield, Utah
About 20 years ago, we acquired a huge lot of the famous Montgomery-Over crandallite nodules that were likely collected in the 1930's that subsequently yielded so many interesting and new phosphates at the time. Recently uncovered here in the warehouse, and before we start dissecting these samples for more detailed investigation, we will offer unanalyzed samples of rich yellow crandallite that may also yield good micros of other species when broken up and evaluated under the 'scope. Nodule sizes range from about 2cm to 6cm across @ just 8.50, 15.00, 25.00 and 40.00 each. Crandallite is guaranteed, the further search is up to you!

DIAMOND (2.71 carats)- Totiya, Katiola Dept., Ivory Coast
A superb, gemmy dodecahedral diamond crystal without matrix, this one suitable for cutting and with a very subtle yellow color. The crystal weighs 2.71 carats and measures about 7x7mm, and a beige inclusion of unknown composition rests just under the perfectly transparent surface of this wonderfully complex, striated and symetrical crystal! Only one available @ 2350.00, well under 900.00 a carat for gem material!

DIETRICHITE on ZINCOCOPIAPITE- Muzhievo, Beregovo, Transcarpathia, Ukraine
A combination of rare minerals, both newly identified from this Au-Pb-Zn deposit near the Hungarian border. The dietrichite occurs as minute, silky white to colorless fibrous crystals scattered on small lamellar crystals of drusy, bright yellow zincocopiapite. Small but surprisingly rich samples for both of these rarities, sizes from about 1.5cm to 2.5cm @ just 120.00 and 165.00 each, all with modest micro potential as well!

EDTOLLITE (IMA #2016-010)- Arsenatnaya Fumerole, Tolbachik Vol. Russia
This NEW SPCEIES was named for Russian geologist and Artic explorer Eduard Vasilievich Toll (1858-1902) who made significant contributions to the geology and geography of Polar Siberia and islands in the Artic Ocean. The mineral occurs as tiny black aggregates mounted on adhesive disks, and these are readily visible at 10x unlike its Al-analog. Formula: K2NaCu5Fe3+O2(AsO4)4, triclinic, IMA # 2016-010. Author's material from the type locality, only a few on hand @ 225.00 each.

EUREKADUMPITE- Centennial Eureka Mine, Juab Co., Utah
This interesting species occurs as micro, turquoise-blue balls and rosettes sparsely scattered on matrix, comprised of densely stacked and radiating platy aggregates showing pearly luster when opened. Formula:(Cu,Zn)16(TeO3)2(AsO4)3Cl(OH)18*7H2O - monoclinic. Approved IMA #2009-072. As a co-author, I am delighted to offer this new mineral, originally published in both Mineral News and Zapiski Rossiyskogo Mineralogicheskogo Obshchestva! Specimens priced according to coverage and quality of micro potential, matrix sizes ranging from about 2cm up to 5cm across @ 25.00, 40.00, 55.00, 75.00, 100.00 and 150.00 each.

FERRIHOLLANDITE- Mt. Sorharas, Ultevis, Lappland, Sweden
Excellent specimens from one of the best localities for this recently redefined barium bearing mineral. Ferrihollandite occurs here as small crystal prisms, sprays, and elongated crystalline cleavages, all richly distributed throught quartz matrix, possibly associated with piemontite or other phases. 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!

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, apple-green 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.

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.

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.

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.

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. Most samples will have good micro potential as well, and specimen sizes range from about 2cm to nearly 5cm across @ 35.00, 50.00 and 65.00 each, depending on coverage.

CLINOZOISITE- Ward Mine, White Pine Co., Nevada
As featured in the September, 2017 issue of Mineral News, this is the first confirmed clinozoisite to be found at this prolific locality. The mineral occurs as pink micro crystals lying flat on a pale grey, cherty matrix. Coverage is relatively lean but obvious, and some have modest micro potential. XRD data is supplied with each sample, and matrix sizes are commensurate with coverage, ranging from about 2cm to 8cm across @ 8.50, 15.00, 30.00 and 45.00 each.

DARAPSKITE- Pampa del Toro, Antofagasta, Chile

DIAMOND - Macle Twin- Oranjemund, Orange River, Namibia
After combing through our extensive inventory of diamond crystals, we have located several gemmy, transparent white macle twins from this prolific area that borders South Africa. These transparent crystals have the shape of an equilateral triangle, rather flat in aspect, but all quite clean and gemmy. Good examples of these interesting crystallographic habits include one of each of the following: 0.81 cts 7x6x2mm @ 480.00; 1.16 cts 8x6x2mm @ 600.00; 1.43 cts 8x6x3mm @ 745.00. List alternates!

ECLOGITE- Newberry, Newberry County, South Carolina
Yes, its a rock, not a mineral, but what a rock! Eclogites are often quite striking in appearance and useful indicators for some diamond occurrences as they represent high-pressure, densely metamorphosed mafic igneous source rocks from mantle depths. These show richly scattered red garnet grains, omphacitic
pyroxene, darker amphiboles and possibly other phases. Specimens from this relatively unexploited locality make superior thin sections and polished sections as well, or you can just study their complexity in hand specimens or under the 'scope! Sizes range from about 3cm to 7cm across, very reasonably offered at just 10.00, 20.00, 30.00 and 45.00 each.

EPIDIDYMITE w/ SERANDITE- Mont St. Hilaire, Quebec, Canada
Somewhat blocky, pseudohexagonal opaque white crystals of this uncommon beryllium mineral to 6mm nicely perched on matrix, the rear of the specimen showing bright pinkish, translucent crystals of serandite covering about 75% of the back of the piece!

adhered and unobtrusive flexible base @ 175.00. One only!

FLUORITE- Fluorite Ridge, nr. Deming, Luna Co. New Mexico
An old E. W. Heinrich specimen and accompanied by his label, comprised of massive, color-zoned fluorite that ranges from the predominant sea-green to white to red-brown included areas, all quite vitreous and showing interesting fluorescent color zones under LW and SW UV as well. The piece weights just over four
(4) pounds(!!) and measures a hefty 12x9x9 cm @ just 45.00.

GALENA- Sullivan Mine, Kimberley, B.C., Canada
Fine-grained, massive galena with admixed sphalerite and pyrhottite result in an odd, banded metallic ore sample in these rich specimens. Old material, acquired with the unrealized thought of preparing neat polished sections, we offer specimens from 5cm to 7cm @ just 15.00 and 20.00 each. Heavy!

GANOMALITE- Jacobsberg Mine, Varmland, Sweden
Exceptionally rich granular white aggregates of ganomalite intergrown with brilliantly fluorescent (redorange) calcite comprising matrix, most with minor dispersed biotite and possibly other species.

KOGARKOITE- Mt. Princeton Hot Spring, Chaffee Co., Colorado
This uncommon species occurs as minute crystal aggregates and relatively pure cellular masses to 0.5mm intergrown in epsomite matrix, offered as crude fragments in a capsule. The material was once mistakenly identified as schairerite, but subsequent XRD work showed it to be this rare Na-F-sulfate mineral. Originally obtained from Adolf Pabst (pabstite) via Forrest Cureton, only a few available @ just 25.00 each.

LEADHILLITE w/ CALEDONITE- Mammoth-St Anthony Mine, Tiger, Arizona
Rich, pale blue masses of leadhillite comprising about half of this rich specimen, also associated with richly scattered, glassy micro cerussite, paralaurionite and possibly other phases, including an area of intense green micro caledonites! There appear to be other unknowns in this vuggy sample, but we don't have the heart to break it up for further analytical work. A neat, representative leadhillite with moderately good color, overall size about 5x4cm @ 250.00. One only!

LEVANTITE (IMA #2017-010)- Har Parsa, Hatrurim Basin, Negev, Israel

We stumbled across a flat of hand-polished Brazilian agate slices recently, these imported some years ago before the craze to dye everything began. These are choice slices with a range of excellent banding, colors and patterns, polished on both sides and ranging from 8cm to 10cm across. Old stuff in an ideal size, offered as mini collections of three different at just 25.00 per lot. Limit two per customer, please; all suitable for framing, and seen elsewhere at three times our price!
UNITED KINGDOM PHARMACOSIDERITE- Various Mines in the United Kingdom An interesting lot of six (6) mounted micromount specimens of pharmacosiderite, each from a different mine in the UK, the majority from various Cornwall localities. The tiny cubic crystals range from green to brown, and it is an unusual offer due to the diversity of localities in the lot. The collection of six different locality specimens is just 35.00 for the lot!
GEM
ANDALUSITE- Brazil
A highly unusual gemstone, here as excellent, sherry colored 6x4mm ovals that are nicely faceted and are eye-clean gems! While these are likely from one of the Bahia mines, we are uncertain of the exact locality beyond Brazil. Rarely offered in this quality and clarity, these well-cut ovals are just 30.00 each. Limit two per customer, please!
