AFGHANITE- Casa Colina Q., Pitigliano, Tuscany, Italy
Afghanite occurs as clear to almost opaque, colorless to white blocky small but sharp crystals scattered in a vuggy matrix. An interesting cancrinite group mineral from this locality collected about 10 years ago, each specimen will probably yield several nice afghanite micros, and these show an obvious fluorescent response under both SW and LW, too! Matrix sizes from about 2cm to nearly 5cm @ 20.00, 30.00, and 45.00 each.

ANALCIME- Chimney Rock Quarry, Somerset Co., New Jersey
Interesting specimens, ex-H. Moore Collection, brought out over 40 years ago in July, 1976 from this prolific deposit in Bridgewater Township. The specimens are partial hemispherical trapezeohedra about 2.5cm across, all showing open cores filled with tiny natrolite needles and crusts. The opaque white faces of the crystals are fairly sharp, some with tiny drusy overcoatings, and all are good representations of the species. Only a few available from this find @ just 20.00 each.

ANHYDRITE in HALITE- Stassfurt, Saxony-Anhalt, Germany

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

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

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

HEDYPHANE in CALCITE (FL)- Vrancice, nr. Pribram, Bohemia, Czech Republic
Dull tan to brownish masses of hedypahne to a few millimeters sparsely scattered in matrix, overwhelmed by the brilliantly fluorescent (redish orange SW UV) calcite embedded in the matrix.

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

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

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

MCGUINNESSITE- Chalk Mountain, Churchill Co., Nevada

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

AFMITE- Bachman Mine, Hellertown, Pennsylvania
Pearly white radiating platelets of this uncommon and relatively new phosphate lightly scattered on cherty limonitic matrix, occasionally with tan crandallite or possibly other species. The mineral was named for the Association Francaise de Mineralogie (AFM) by Kampf et al in 2010, and structurally confirmed from this U.S. locality in 2012. Only a few specimens available averaging 4cm to 5cm and priced according to richness and coverage @ 40.00, 60.00 and 75.00 each.

ALLANITE-(Ce)- nr. Reno, Washoe County, Nevada
Nicely formed crystal sections of the rare earth mineral allanite-Ce are offered here as free standing with little or no matrix, all with good prism faces. These are black, occasionally with trace feldspar and with typical dull luster, and most show several good faces. Collected over 30 years ago from a small prospect about 12 miles north of Reno, priced according to crystal quality and size, overall 1-2.5cm @ 20.00, 30.00 and 40.00 each.

ARSENOPYRITE with HEMATITE- Paguk Mine, nr. Taegon, South Korea
This sample sports a thick, jagged mass of aresenopyrite protruding from one end of a hematite-rich matrix that shows minor ore banding in rock matrix. Originally labelled in an old collection as "danaite", a cobalt-rich variety of arsenopyrite, we analyzed the piece and found no significant cobalt present. From an obscure and unrecorded locality, complete with our original chemical analysis, specimen size about 7x5cm @ just 50.00 (the cost of our analytical work!) with a former collection label of unknown origin. One only!

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

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

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

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

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

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

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

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

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

HYDROZINCITE- Ojuela Mine, Mapimi, Durango, Mexico

Matrix sizes from 1.5cm to 5cm @ 5.00, 10.00, 20.00 and 35.00 each, a few to 8x5cm @ 55.00 each.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

TINZENITE- Falotta, nr. Tinzen, Grisons, Switzerland
Dark, nearly black braunite and white barite comprise the matrix of these rather lean samples, here showing pinkish orange tinzenite lightly scattered in isolated areas of the specimens.

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

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

CALCIOMURMANITE (IMA 2014-103)- Mt. Pyalkimpor, Lovozero, Kola, Russia

The material is quiteheavy and takes an excellent polish, sold for lapiday use starting at $100 a pound! Our samples are rough chunks from 4cm to 11cm across, certain to turns your hands black when handling, offered at just 20.00, 35.00, 50.00 and 75.00 each. A few specimens with one cut face and lightly buff polished, 5cm to 9cm across the face @ 30.00, 55.00 and 80.00 each

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

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

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

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

20.00, 35.00 and 55.00 each.

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

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

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

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

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

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

Small but vibrantly colored, electric blue crystalline hauyne, crudely crystallized and extracted from pumice matrix, typical specimen size averaging about 4mm across of pure material and showing some faces as well. Excellent, gemmy color @ just 12.00 each from this Eifel locality.

HUBEITE - Daye Mine, Huang Si, Hubei Province PR China
This uncommon species occurs as attractive, well formed, glassy brown, micro prismatic crystals to 6mm richly scattered on matrix, sometimes intergrown on and about calcite crystals etc. Formula: Ca2Mn2+Fe3+SiO4(OH)(H2O)2. Very interesting specimens from the type locality, generous sizes averaging 9cm across @ just 150.00 each. A few with elongated pink inesite crystals @ 200.00 each, the latter very attractive and quite superb!

JAHNSITE-(CaMnMn)- Bull Moose Mine, Custer Co., South Dakota
Excellent micro crystals of the (CaMnMn) member of the jahnsite series, here as tiny, yellowish green glassy crystals perched in vugs in massive primary phosphate-rich matrix. EDS work on these oddly-colored micro crystals repeatedly showed the Mn:Fe ratio near 1:1 to 3:2, with low Mg present as well. All samples witharrows and accompanied by a copy of our analytical work! Although small, these are well formed and make for excellent micros with a wide variety of secondary phosphate associations, with overall matrix sizes ranging from about 1.5cm to 4cm across @ 20.00, 30.00, and 45.00. Nice!

KOBELLITE- Nello Teer Q., Raleigh, Wake Co., North Carolina
This relatively small locality has produced about two dozen species, most from early workings of the quarry prior to 1970 that were subsequently analyzed by modern methods. The kobellite occurs as rich, silvery-grey metallic masses richly scattered on matrix and potentially intergrown with other uncommon sulfosalts. Formula: Pb22Cu4(Bi,Sb)30S69, the Bi-analog of the rare mineral tintinaite. More commonly known from Sweden, these are, by far, the best U.S. occurrence for the mineral we have ever seen. Specimens range in size from 3.5cm to 7cm @ just 25.00, 40.00 and 55.00 each, and one monster sample with a saw-cut base measuring 20x9cm @ 200.00!

LUNEBURGITE- Mejillones, Antofagasta, Chile
Nearly pure white masses of this rare phosphate comprising matrix. From one of the few described localities for the species, we offer these as small fragments about 1mm across @ 40.00 each, first obtained in 1992 from this locality. Only a few on hand!

MAHNERTITE- Cap Garonne Mine, Le Pradet, Var, France
Superb, colorful, bright blue micro crystals and groups of this uncommon, complex copper arsenate mineral richly scattered on matrix, all providing good micro potential as well. From the type locality for the species, we have just one small sample just under 1cm in size @ 150.00. Excellent, but one only!

MALACHITE- Nevada Scheelite Mine, Mineral Co., Nevada
A newly reported mineral for the locality, malachite occurs here as small, radiating felted masses and micro acicular crystals scattered on the surface of a vuggy, limonitic quartz matrix. Other species may be present, and this material, collected at the 200 ft. level some time ago, deserves additional study. Only a few TNs available, all with micro potential, @ just 10.00 each.

METARAUCHITE- Eduard Mine, Jachymov, Bohemia, Czech Republic
Collected from the Schweitzer Vein at this, the type locality for the species, metarauchite occurs as dull yellowish green crusts well-scattered over dehydrated clay-like matrix, also filling apparent expansion cracks in the matrix as well. A rare, hydrated nickel-uranium arsenate, nicely fluorescent, only one 2cm TN available, ex-Vajdak, @ 395.00. List alternates.

NATROCHALCITE- Chuquicamata, Antofagasta Prov., Chile
Excellent apple-green aggregates of this uncommon mineral lightly scattered over matrix. These are older specimens, occasionally with other minor associations, classic material from TNs to 4cm across @ 20.00, 35.00 and 55.00 each.

PICROPHARMACOLITE, REALGAR etc- White Caps Mine, Manhattan, Nye Co. Nevada
An exceptional lot of rich, handsome specimens from this prolific mine, the picropharmacolite occurs as tiny, white spiny balls of acicular crystals to severall millimeters across, well-scattered on matrix, typically over a pale orange-red druse of realgar and occasionally with transparent gypsum, yellow sulfur and/or white globular pharmacolite. A new mineral for the locality, SEM/EDS verified, and with great micro potential as well. Overall matrix sizes range from about 3cm to 8cm across @ just 15.00, 25.00, 40.00, 65.00 and 100.00 each. Superb!

SCAPOLITE variety WERNERITE- Newtown, Fairfield Co., Connecticut

The piece is ex-Michigan College of Mines and is accompanied by three old labels from the school. A classic U.S. locality for this marialite-meionite mid-member, not fluorescent, overall size about 6x5cm @ 45.00. One only.

SMITHSONITE (Dry Bone Ore)- McCay Tract, Shullsburg, Lafayette C Wisconsin
Discovered in the mid-1800s, the Shullsburg area had numerous lead-zinc deposits that were exploited for more than a hundred years. This specimen is ex-G.A. Koenig (1844-1913) and Michigan Mining College, comprised of brownish, weathered "dry bone ore" smithsonite, accompanied by two old labels identifying the origional collecting site as "McCay's Tract", apparently one of the many obscure deposits worked more than a century ago. Substantial and old but decidedly ugly, overall about 15x9 cm, an historic piece @ just 75.00.SULFUR- Steamboat Springs, Washoe Co., Nevada Rich, bright yellow crystals and druses of native sulfur fully covering silaceous sinter matrix. Ols and colorful material as recently described in the January, 2017 issue of Mineral News, most with good micro potential as well, and all quite reasonable in sizes from 3cm to nearly 8cm @ 8.50, 15.00, 25.00 and 35.00 each.

TARBUTTITE- Skorpion Mine, Rosh Pinah, Karas, Namibia
Excellent, densely aggregated small crystalline aggregates and triclinic groups of transparent to pale green tarbuttite forming seams and exposed fields of this uncommon anhydrous zinc phosphate on matrix. An uncommon color, habit and occurrence for the mineral that was discovered about 10 years ago (and offered at outrageous prices!), we have a few representative 5cm specimens on hand @ just 55.00 each.

TORRECILLSDITE (IMA 2013-112)- Torrecillas Mine, Salar Grande, Chile
This relatively NEW SPECIES occurs here as extremely small, colorless aggregates of high luster sparsely scattered on grayish white anhydrite/gypsum matrix, potentially with white tamarugite and other phases present. Formula: Na(As,Sb)3+4O6Cl, orthorhombic, IMA # 2013-112. Type locality material, but otherwise
difficult to differentiate, specimens average about 2cm across @ 55.00 each. List alternates!

TOURMALINE etc.- Elliston, Powell Co., Montana
Numerous tiny black crystals of a vitreous tourmaline group mineral are lightly scattered in several areas of this old specimen, best seen under low magnification. Minor quartz and other unidentified phases are present as well and deserve further study. Originally ex-Kiril Spiroff (1901-1981, the mineral namee for spiroffite) and donated to the Michigan College of Mines where he became curator after Seaman's death in 1938. His early career was as a mining engineer in the West before returning to Michigan. The locality label, specifying "Hidden Treasure Gulch" is unrecorded in Mindat, and the Elliston area is covered with numerous claims and old mines (Big Dick, Golden Anchor, Evening Star etc.). A superficially ugly rock, overall size about 6x4cm @ 55.00. For the connoisseur of Montana locality minerals, the piece has some historic provenance as well!

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

VESUVIANITE- nr. Blue Bird Mine, Mineral Co., Nevada
From a new find at an unnamed prospect near the Blue Bird Mine, we have a good selection of small, pistachio green vesuvianite crystals richly lining exposed seams and cavities, most carefully etched out of calcite and therefore showing good prism faces and terminations, most samples with full surface coverage as well. Recently featured in a Mineral News article, these specimens range from about 2.5cm to 8cm across, priced very reasonably at just 7.50, 15.00, 25.00 and 45.00 each, a few better to 75.00. Nice stuff for Nevada!

VOLKOVSKITE- Boulby Mine, North Yorkshire, England
This rare borate mineral is a member of the veatchite group, and it is found at only a handful of localities worldwide. These specimens are thin, transparent crystalline platelets and cleavages up to 2x1cm in crosssection with a bare trace of pinkish hilgardite (?) providing a hint of color. Only a few specimens available, sizes from about 1cm to 2cm long @ 45.00, 85.00 and 125.00 each. List alternates!

XENOTIME-(Y)- Novo Horizonte, Bahia, Brazil

ZALESIITE- Gold Hill Mine, Tooele Co., Utah
Although we have offered this relatively uncommon species before, this is from the confirmed locality find
(see Mineral News, Vol 21 #8), with the mineral occurring as pale yellowish green acicular crystals and sprays perched on a garnet skarn matrix. Good micro material selected from a larger lot, with specimen sizes averaging about 1.5-2cm temporarily mounted in clear topped micro boxes at just 20.00 each, occasionally with minor conichalcite. Only a few available!

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

FORSTERITE var. PERIDOT- San Carlos, Gila Co., Arizona
A small but select lot of excellent, yellow-green forsterite variety peridot cut as faceted octagons from this
well-known Arizona locality. These are eye clean, well-cut 7x5mm octagons, competitively priced at just
10.00 per stone, or a lot of 5 for just 40.00. If you want a large variety of shapes, we can offer an excellent
buy of 20 faceted peridots in assorted shapes for just 125.00, with about 20 cts as the average total carat
weight for each lot. A real bargain in these large lots - don't miss them

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