CATALOG 22206 – Volume 49, No. 6

ACANTHITE on NATIVE SILVER- Hongda Mine, Lingqui, Shanxi, PR China
An exceptional specimen comprised of thick, curved native silver masses and "ramshorns", all fully encrusted with
rich, metallic greyish black acanthite crystals. While individual acanthites are quite small, the specimen presents nicely and measures 8.5 x 6 x 3 cm, weighing a hefty 250 g! The small cabinet specimen is priced (take a deep breathe!) at 3500.00. Needless to say, one only!

BATISITE- Murunskii Massif, Aldan Shield, Russia
Dark brown flattened crystals and aggregates of this moderately rare mineral forms somewhat flattened crystals
scattered on white feldspar matrix, typically with black magnesio-arfvedsonite ggregates as well. Superb for the
species, sizes from 2.5cm to 5cm across @ 45.00, 75.00 and 125.00 each.

BERYL variety EMERALD- Little Switzerland, Mitchell Co., North Carolina
Small, bright green emeralds, typically as partial crystals or aggregates, lightly scattered in quartz matrix and
associated with prolific, thin crystals of black (schorl) tourmaline. There are numerous prospects in the area, some attributed simply to "Spruce Pine", and these are Ex-Florence Mecke Collection who was active from the 1930s to late 1960s. Specimens average about 4cm across @ 50.00 each.

CHEROKEEITE (IMA2022-016)- Redmond Mine, Haywood Co., North Carolina
A recently approved NEW SPECIES from this prolific locality, presented here in several habits, either as tiny crystals with wedge-shaped terminations, more typically as spherical masses of complex intergrowths. Color is typically colorless to grey, but has also been confirmed in pale blue or pale pink bladed crystals as well.
Formula:[Pb2Zn(OH)4](SO4) - monoclinic - IMA # 2022- 016). Author's material from the type locality, Small TNs to
a few 3cm samples, all with arrows, @ 100.00, 150.00, 250.00, 300.00 and 400.00 each, depending on quality and associations.

CLINOZOISITE- Hunting Hill Quarry, Rockville, Maryland
From an uncommon eastern U.S. locality, we have uncovered several well-crystallized specimens of rod-like, pale,
yellowish-green crystals of clinozoisite well scattered on matrix. Excellent matrix specimens with good coverage and crystals to 1cm tall, often with minor, calcite. Habits are clearly elongated, with matrix sizes from 3cm to 6cm across @ 25.00, 35.00 and 45.00 each, each supplied with a copy of our EDS analysis completed in 2011.

CUPRIAN DESCLOIZITE- Whale Mine, Goodsprings Dis, Clark C Nevada
From material collected years ago, we have a few specimens of black, micro-crystallized flattened spears of
orthorhombic copper-rich descloizite (an anhydrous lead-zinc vanadate) scattered on matrix. Originally supplied to us as mottramite, our analytical work (copy supplied) shows that these are actually Zn-dominant descloizite with a high, but subordinate, Cu content. Quite good for micromounting and TNs, the locality was last mined circa 1943. Fairly obscure locality, specimens from about 2cm to 5cm across @ just 12.50, 20.000 and 25.00 each.

DATOLITE- Westfield, Hampden Co., Massachusetts
Clear to pale green crystals of datolite richly scattered or comprising matrix. A classic eastern U.S. locality, these
collected many years ago by G. Fred Lincks. Overall group sizes from 3cm to 6cm @ 15.00, 25.00, 45.00 & 65.00. A few larger to 12cm @ 125.00; inquire!

DYPINGITE- Brosso Mine, Turin, Piedmont, Italy
We recently uncovered some fairly large specimens of older material that are richly covered in white balls of dypingite. In cross section, the tiny balls show a pearly, radiating cross section, and these would supply numerous excellent micromounts if trimmed. One old label suggests these were collected at the 375 meter level, but it does not specifiy which side (Salvere or Fortune) of the mine. Rich specimens, sizes from about 5cm to 10cm across @ 25.00, 50.00 and 75.00 each depending on size/coverage.

FINESCREEKITE (IMA2022-030)- Redmond Mine, Haywood Co., North Carolina
Another NEW SPECIES from this small but prolific locality, here as minute, rounded colorless to very pale yellowish
stacked plates on altered sulfide matrix. Highly lustrous twins are typical, Formula [Pb4(OH)4](S2O3)2 - orthorhombic - IMA2022-030. Author's material from the type locality, small TNs with arrows at 250.00, 375.00 and one @ 450.00, depending on quality and associations. Very limited supply!

FLUORO-RICHTERITE- Wilberforce, Haliburton Co., Ont., Canada
Thick, columnar crystal sections of this interesting and complex amphibole without matrix, surprisingly lareg and
relatively pure material collected in the distant past from an old University collection. The specimens show excellent, elogated prism faces and are otherwise unterminated, crystal section lengths from 3cm to 5cm tall at just 15.00 and 25.00 each.

GIACOVAZZOITE (IMA2018-165)- Monte Arsiccio Mine, Tuscany, Italy
This relatively NEW SPECIES occurs here as minute, orange-brown crystalline aggregates and tiny, barrel-shaped
prismatic crystals sparsely scattered in a punky, sulfate-rich matrix. Formula: K5Fe3+3O(SO4)6*10H2O, monoclinic, IMA2018-165. Type locality material, TN sizes to 2.5cm across @ 125.00 each, some with modest micro potential.

HEULANDITE-Ca- Prospect Park, Passaic Co., New Jersey
An old-time specimen from the H.E. Moore Collection, acquired by him in 1950 from this once-prolific locality. The
specimen is comprised of thousands of heulandite-Ca crystals that range from 2mm to 4mm long, richly comprising a vuggy and convoluted cabinet specimen. A few small (5-7mm) honey-colored stilbite-Ca crystals are lightly perched on the pearly heulandite-Ca sample as well, and overall size is a generous 10x7 cm @ just 48.00. One only!

HOGTUVAITE- Bordvedaga, Hogtuva, Rana, Norway
Dark grey to nearly black needles and flattened sprays of hogtuvaite (1-2cm in length) pierce a whitish matrix of
phenakite-gneiss that also bears some biotite and possibly other phases. Rich specimens from the type locality for the species, 2.5cm to large 11cm specimens @ 20.00, 40.00, 65.00 and 95.00 each. Rich!

HUTCHINSONITE w/ ORPIMENT etc.- Quiruvilca Mine, La Libertad, Peru
Some old-time material from the late 1970s comprised of small (to 4mm) metallic crystals of reddish black hutinsonite nicely scattered with deep orange orpiment the latter as tiny crystallized masses fully covering one surface of these handsome matrix specimens, some with small, clear tabular barite crystals etc. Great micro potential as well, two sizes on hand from 5cm to 10cm across @ 85.00 and 175.00 each

ILMAJOKITE-(Ce)- Yubileinaya Pegmatite, Mt. Karasurt, Russia
A rare mineral from the Lovozero Massif, discovered in the early 1970's and has never been found anywhere else in the world since! Reported to be the third-most complex structure among all known mineral species, this pale yellowish material is very sparsely scattered on matrix, typically with white natrolite and occasionally with red eudialyte and possibly other species on the "larger" specimens. Not much to look at, small fragments in a capsule @ 45.00; a couple of matrix specimens: 1.2cm @ 125.00, 2.5cm @ 200.00 each. Very limited availability.!

KYANITE- Tunnel Pegmatite, Rabun Co., Georgia
An unusual locality specimen, comprised of a crude, single kyanite crystal that is dark blue but iron-stained, collected by E.W. Heinrich. The locality is not listed in Mindat and likely is representative of the kyanite-rich, Laurel Creek Complex area. Only two crystals on hand, about 5cm x 1.5cm @ 40.00 each.

MAGGANASITE (IMA2021-112)- Arsenatnaya Fumerole, Tolbachik, Russia
Another NEW SPECIES from this well-known Kamchatka volcano, here as very small (to 0.5mm) of reddish brown to
golden brown crude prismatic crystals on brown scoria matrix. Formula: CuFe3+O(AsO4)3 - triclinic, IMA2021-
112. Some of the better specimens are associated with green lammerite or rarely, yellowish paralammerite, and most typically have minor black hematite, white sanidine and colorless, micro prismatic langbeinite as well, Author's material, sizes from 1.5cm to 2.5cm @ 150.00 and 200.00 each.

MALACHITE pseudo @ AZURITE- Sir Dominick Mine, Arkaroola, S.A., Australia
Dark green malachite richly covers these samples, here as wedge shaped to radiating lath like pseudomorphs after azurite crystals. This material was described in a 1980 article in Mineralogical Record (Vol. 11 No. 2, sadly in black and white). Colorful stuff with moderately good psuedomorphic azurite habit, overall sizes from 2cm to 4cm across @ 15.00, 25.00 and 40.00 each. Relatively inexpensive and neat stuff!

MOLYBDENITE- Knabenheiem nr. Flekkefiord, Norway
Old material from this famous Dana locality, collected by Dr. E. Wm. Heinrich many years ago prior to his subsequent editorship of American Mineralogist! Small greyish plates of molybdendite are well scattered in matrix, some with micro potential as well, with specimen sizes from about 2.5cm to 6cm @ 10.00, 20.00 and 35.00 each. Photocopy of Heinrich label accompanies each sample!

NOONKANBAHITE- Tausonitovaya Gorka, Murunskii Massif, Russia
This rare species occurs as yellowish brown lamellar crystals to several mm across, scattered in a greenish aegirine-kalsilite rock matrix. This old name was retained and recent structural studies from this (the type) locality revealed its unique nature as a new species. Formula: BaKNaTi2(Si4O12)O2 - orthorhombic, IMA #2009-059. The Ba-analog of shcherbakovite and the K-analog of batisite. Specimens range from about 2cm to 5cm across @ 75.00, 100.00 and 175.00 for the richest, all depending on size and coverage.

PARSETTENSITE- Parsettens Alp, Oberhalbstein, Switzerland
From the Grisons Canton type locality for both parsettensite and associated tinzenite and sursassite, parsettensite occurs as scattered reddish-brown to brown masses in quartz, typically with minor hematite or orange brown crystalline tinzenite. Good quality specimens, sizes from 2cm to 7cm at 35.00, 65.00, 90.00 and 125.00 each, most obtained years ago from the Natural History Museum in Bern. List alternates.

PICKERINGITE (Zn-Co Rich)- Chocolate Drop Mine, San Juan Co., Utah
Exceptionally attractive, bright pink intergrowths of elongated, fibrous pickeringite comprising entire specimens. Each sample is accompanied by a copy of our analytical work, the confirming X-ray spectra shows minor Zn and Co (likely responsible for the great color!) in these samples. Erroneously sold elsewhere as wupatkiite (its not!), and the lead article in the September, 2022 Mineral News provides additional details. Delicate material, carefully packaged to withstand the USPS, in specimen sizes from 2cm to 7cm across @ 25.00, 50.00, 75.00 and 100.00 each, depending on quality and size. Wonderful for the species!

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

REINHARDBRAUNSITE- Bellerberg, Rheinland-Palatinate, Germany
This uncommon member of the humite group occurs as very small pinkish masses scattered in matrix, typically
associated with brownmillerite or possibly other phases. Once called calciochondrodite, the species was named about 40 years ago to honor Reinhard Brauns, a famous mineralogist in the late 1800's to early 1900's. Specimens range from about 1cm up to nearly 3cm @ 30.00, 45.00 and 65.00 each. Limit one per order, please.

ROSICKYITE- Pacific Drill Hole, Ventura Co., California
Sharp, yellow transparent micro crystals of rosickyite richly scattered over the surface of a brown shale matrix. Old
stuff and good micro material as well, these from a drill core in the Pacific Ocean extracted off the coast of Ventura County. Sizes from 1.5 to nearly 3cm @ 10.00, 17.50 and 30.00 each.

SARKINITE- Harstigen, Varmland, Sweden
A single specimen comprised of typical manganese ore material, showing very tiny, drusy crystals of pinkish sarkinite on an exposed fracture surface, associated with rather ugly, brownish caryopilite as well. An old speimen, size about 7x5cm @ 85.00, type locality material!

SURSASSITE- Strategic Mine, Woodstock, N.B., Canada
This uncommon mineral occurs here as orange-brown, somewhat fibrous masses in thin seams running through dense, dark brown manganese ore matrix. From the only known Canadian locality, specimens are moderately rich and quite obvious, sizes from 2.5cm to 4.5cm @ 20.00, 30.00 and 45.00 each.

TAKEDAITE- Fuka, Bicchu-cho, Okayama Pref., Japan
This relatively new mineral, a calcium borate, [Ca3B2O6] occurs as greyish white dense aggregates of minute grains, often with intermixed calcite and an unidentified minor borate mineral impurity, comprising matrix. From the type locality for the species in the underground workings, suprisingly large, analyzed (XRD/IRS) specimens from about 1.4cm to 3.5cm specimens @ 35.00, 55.00 and 80.00 each; remarkable 6cm specimens @ 150.00 each. Only a few available!

TALC- Huntley Mine, Lodi District, Nye Co. Nevada
Slick, pearly white, greasy masses of richly scattered talc largely comprising these interesting locality specimens.
Smaller samples are relatively clean, while the larger ones often have altered feldspar matrix associated. Specimens range from about 2.5cm to 7cm across @ 10.00, 20.00 and 35.00 each. Slippery stuff from an obscure locality; pure material suitable for analytical standards @ $0.50 per gram.!

TENORITE- Algomah Mine, nr Mass, Ontonagon Co. Michigan
Black masses of tenorite scattered in brownish-red, copper ore rock matrix, most specimens with apparent malachite and possibly other secondary copper minerals. Last producing circa 1914, material from this old property has yielded some interesting cutting material, micros etc. Specimens range from about 2cm-4cm @ just 8.00, 12.50, and 20.00 each; a few to nearly 6cm across @ 40.00 each.

VANDENBRANDEITE- Musonoi Extension, Katanga(Shaba), Dem Rep Congo
A selection of half a dozen excellent vandenbrandeite specimens, most from the Vandall King uranium collection, here showing well formed, dark greenish black vandenbrandeite crystals to several millimeters isolated and in small groups on uranium-rich, digenite ore matrix, occasionally associated with other uranium minerals such as kasolite, soddyite, cuprosklodowskite etc.. Fine for the species from this prolific (formerly Zaire) locality, some with good micro potential as well, specimens from 2cm to 5cm priced according to quality @ 50.00, 75.00, 100.00 and 150.00 each.

VILLIAUMITE- Khibiny Massif, Murmnask Oblast, Kola, Russia
Another excellent crystallized example from the Jensen thumbnail collection (#5370), here as a very dark red, blocky sample of pure villiaumite without matrix. Likely from the Koashva Open Pit, the specimen was acquired in 2004 and measures 3cm tall @ just 125.00. A monster 6.5x5x4 cm specimen at 450.00 also on hand. One of each only.

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, @ 30.00, 45.00 and 65.00 each. Excellent for the price!

WULFENITE etc.- Blue Bell Mine, Zzyzx, San Bernadino California
This prolific mine had been worked since 1885, and it currently boasts over 100 different minerals including five type species. We have several flats of assorted material collected there in 2008, and we have set aside a handful of micro wulfenite specimens from that lot. The crystals are very small, platy yellow to slightly orange in color, generally lean on matrix surface and potentially associated with other phases. Fairly ugly in hand specimens, but worthwhile searching under the 'scope! Specimens range from about 4cm to 7cm @ just 7.50, 12.50 and 20.00 each. Cheap!

WURTZITE- Merelani, Arusha, Tanzania
From the 2012 find, these are deep red to red-brown, somewhat tabular aggregates and cleavages of X-ray confirmed wurtzite, the dimorph of sphalerite. These are matrix-free, pure and solid, and are highly unusual for the locality, and the first (and only!) confirmed find of the mineral in Tanzania! XRD data shows that these are the 4H polytype of the mineral! Sizes are small but pure with a wonderful red dark color, ranging from about 5mm to nearly 15mm across @ 20.00, 40.00, 60.00 and 95.00 each. Exceptional find from ten years ago!

ZINCOCHENITE (IMA2022-025)- Redmond Mine, Haywood Co., North Carolina
This NEW SPECIES is the Zn-analog of chenite, occurring here at the type locality as minute, very pale blue to
colorless tabular crystals in tight groups on matrix. Formula: Pb4Zn(OH)6(SO4)2 - triclinic, IMA2022-025, author's
material. Small specimens with arrows, ranging from about 1cm to 1.5cm priced according to quality at 150.00 and 200.00 each. Only a few available!

CATALOG 22205 – Volume 49, No. 5

ACANTHITE pseudo @ PYRARGYRITE- Guanajuato Municipality, Guanajuato, Mexico
Likely from the famous San Juan de Rayas Mine, this excellent thumbnail shows elongated prisims of acanthite pseudos after pyrargyrite on a chalcopyrite coated Ag-sulfide matrix, beautifully presented and once given as a gift from Willard Perkins, famous as the inventor of the "perky box", presented to Scott Williams in 1986. A fine quality specimen, mounted in a "perky box", of course, @ 150.00.

ALMANDINE var: PYRALMANDINE- Fazenda Rodolita, Peixe, Tocantins, Brazil
Crude rounded crystals and masses of deep red garnet without matrix. Our EDS work shsows it is primarily almandine, but with a minor pyrope composition. Some call this "rhodolite", but it is more properly "pyralmandine" in composition. The chunks were intended as faceting material, and the crude masses range from about 100 carats to 200 carats each (2cm to 3cm), with the larger ones showing some occasional rounded, crystal faces. Cheap enough to tumble or try your hand at faceting, specimens are only 5.00, 7.50 and 10.00 each, or get a small lot of 1000 carats (5-7 samples) for just 25.00 per lot. Interesting locality material, SEM analysis included!

ANTHOINITE- Nyababingo Mine, Kigali, Rwanda
This rare tungsten mineral occurds here as dull, brownish aggregates on matrix, color typically imparted by minor Fe-content. First reported from the locality about 15 years ago, little of the material has reached the specimen market. We have one small sample on hand, overall nearly 1cm across with good coverage @ 85.00. List alternates!

APJOHNITE- 20th Century Mine, Nye Co., Nevada
An unusual specimen locality and species, the mine located SW of Urania Peak in the Cactus Range. The mineral
is a pearly, yellowish elongated, aggregated mass about 3cm tall and otherwise matrix-free. Ex-Jensen Collection,
noted as identification done at the Nevada Bureau of Mines & Geology about 25 years ago, a nicely mounted and
fairly attractive thumbnail for the species @ 75.00. One only.

ARAGONITE (multiple generation)- Stevenson-Bennett Mine, Dona Ana Co. New M
Found carefully wrapped in an old King Edward cigar box (the cigars were 6 cents each at the time!), we recently
uncovered a small lot of interesting aragonite specimens from this old U.S. locality, here as somewhat pearly white botryoids with an additional generation of spikey, transparent aragonite needles nicely perched over them and on thin matrix. The samples are mildly fluorescent under both SW (green) and LW (yellow) UV. The locality was first discovered in the 1870s, and it has a long & rich specimen history as well. Only a few samples on hand, these ranging from about 2.5cm to 4cm across @ just 7.50, 15.00 and 25.00 each. Moderately attractive, too!

ARAGONITE/CALCITE SEPTARIAN- Betsiboka Region, Madagascar
Unusual septarian nodules containing dark brownish calcite crystal druses filling voids and seams in an aragonite-rich matrix. These specimens have been native-cobbed, shaped and polished to resemble smooth egg-like structures, locally marketed as "Dragon's Eggs". Interesting specimens, sizes from about 6cm to 12cm tall @ 50.00, 80.00, 125.00 and 200.00 each. A few larger, to 20cm @ 350.00. Interesting decorator items with a mineral theme!

BARITE with SULFUR- Tarnobrzeg, Subcarpathian Volvodeship, Poland
Moderately attractive, tan to greyish white bladed barite crystals fully covering or comprising matrix, typically with
small masses of bright yellow native sulfur. A well-known locality, we obtained these in early 1989, and just recent
uncovered here once again. Specimens are well-crystallized and range from about 4cm to 6cm across, priced at
20.00, 30.00 and 40.00 each, depending on quality and size.

BIXBYITE-(Mn)- Thomas Range, Juab Co., Utah
Sharp crystals of adamantine, black bixbyite-(Mn), most sitting on a greyish rhyolite matrixix. From the type locality
for the Mn-dominant species, individual crystals range from about 3mm to nearly 6mm across(!!) some with minor
octahedral modifications, and occasionally with minor topaz evident as well. Matrix specimens range from about
2cm to 5cm across, priced according to quality, size and associations @ just 15.00, 25.00 and 45.00 each. Only a
few larger crystals available!

CALCITE (Cobaltoan)- Kolwezi, Lualaba, DR Congo
Attractive, small bright pink to darker pink vitreous crystals richly scattered as colorful druses on dolomitic rock
matrix. Our analytical work shows that the material has a moderately high Mg content, thus leaning towards the
border between cobaltoan dolomite and cobaltoan calcite. Pretty material, some with tiny malachite masses, sizes from about 2.5cm to nearly 7cm across @ 10.00, 20.00, 35.00 and 55.00 each.

CERUSSITE- Daoping Mine, Guangxi Zhuang, PR China
From a recent find, these are thick, reticulated groups of flattened cerussite crystals forming oddly-shaped rosettes and smaller, elongated blades with little or no matrix. Interesting and moderately unusual for the larger samples, specimens range from white TNs @ 35.00, to larger 3cm to 4.5cm @ 75.00, 100.00 and 150.00 each.

CORONADITE- Broken Hill, New South Wales, Australia
Rather ugly stuff, composed of brownish black masses of coronadite richly scattered in hard and brittle limonitic
matrix, typically admixed with other, similarly ugly, oxide phases. Collected by Forrest Cureton many years ago
during one of his Australian journeys, we have a small selection of fairly rich (but very ugly) samples from 2.5cm to
nearly 10cm across @ just 12.50, 25.00, 40.00, 55.00 and 75.00 each.

CORUNDUM w/ “Smaragdite Amphibole”- Buck Creek, Clay Co., North Carolina
Small red splashes of corundum variety ruby lightly scattered in dense, medium green admixed amphibole
(smaragdite) matrix. Some have called this zoisite (incorrectly, despite its resemblance to Tanzanian material), but
XRD confirms it as an amphibole, with EDS suggesting a possible iron-deficient, potassic-chloropargasite or
edenitic composition instead! Rather than spend our short lives figuring out amphibole nomenclature, we'll just
provide copies of the analytical details and dump it on you, free with each specimen that measures 3cm to 5cm
across @ just 20.00, 25.00 and 35.00 each.

EDWARDSITE- Tsumeb, Oshikoto Region, Namibia
This rare copper-cadmium sulfate mineral occurs here as very tiny, pale blue crystalline aggregates sparsely
scattered on germanite/chalcocite ore matrix. First discovered at Broken Hill (NSW),it only recently has been
confirmed from Tsumeb, bringing the locality's species count to an astounding 340 minerals! Only one specimen
available, about 1cm across with modest micro potential as well @ 245.00.

ERIONITE-K- Chase Creek, nr. Falkland, B.C., Canada
Microscopic prismatic crystals of white erionite-K line elliptical vesicles in dark tan to black matrix. Overall
appearance attractive due to contrasting color of the stretched bubbles, some with good micro potential. Sizes from 2.5cm to nearly 4cm @ 15.00, 25.00 and 40.00 each.

FERRIERITE-Mg- Kamloops Lake, British Columbia, Canada
The most common end-member composition of this zeolite mineral, ferrierite-(Mg) occurs as colorless to slightly orange-hued, micro divergent radial aggregates lining an opal-like chalcedony matrix. These range from more-or less solid pieces to odd looking convoluted vuggy masses, all with good micro potential, and from the type locality
for the species. Well formed and passably attractive, in sizes from small micros as crystallized rims on chalcedony
to 7mm @ 10.00, to more solid masses of 2cm up to 4cm across @ 35.00, 55.00 and 75.00 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.

FLUORITE- Xianghualing Ore field, Linwu, Hunan, PR China
China continues to produce varied specimens of multi-colored fluorite from this famous ore field. Our latest
shipment had a small, hand-picked assortment of sea-blue chunks, many with a slightly greenish cast and typically overlaying pale purple material as well. These are quite transparent and superb when back-lit, and one can expect to see a range different shades in virtually every specimen! These are not particularly well-crystallized specimens, but crystal faces are evident throughout each sample. Sizes range from about 4.5cm to 7cm across @ 75.00 and 150.00 each, one larger 12x7cm sample @ 395.00.

FLUORITE with GALENA, SIDERITE- Derbyshire, England, United Kingdom
A marvelous, old cabinet specimen, ex-Robert Hesse Collection (1894-1984, assistant curator at the Academy of
Natural Sciences in Philadelphia) and obtained by him in a trade with the University of Pennsylvania in 1941! Later
acquired by Dick Hauck and sold to Dr. Eugene Sensel (1911-2000) prior to his death. The specimen shows sharp, colorless to pale yellowish cubic fluorite crystals to 2cm richly scattered across the entire top of this large specimen, rimmed by platy aggregates of pale brown siderite with small galena crystals protruding from the siderite. Brilliantly fluorescent, of course, and a classic example from a locality. Overall 13x8x6 cm @ just 650.00 and likely worth considerably more today!

GOETHITE ps @ ANKERITE on QUARTZ- Aiguille D'Arves, Savoie, France
Dark brownish balls to 5mm of goethite pseudomorphing groups of ankerite globules nicely scattered over
transparent quartz crystals and groups. An unusual locality and pseudomorph, matrix sizes from 2.5cm to 7cm @
10.00, 20.00, 35.00 and 45.00 each.

GOLD- Fraser River, nr.Lytton, B.C., Canada
Small placer nuggets of native gold, collected circa 1951, and recently found in an old collection in our warehouse. The village of Lytton was completed destroyed by a wildfire in June, 2021. The specimens are leafy or typically flattened and somewhat rounded, and our EDS work (copy supplied) shows 3% to 4% silver as well. Sizes about 3mm to 5mm across @ just 35.00 to 50.00 each. Old stuff!

HAYWOODITE (IMA 2021-115)- Redmond Mine, Haywood Co., North Carolina

shaped prisms sparsely scattered on galena-ricj matrix. Formula: [Pb(H2O)10][Zn12(OH)20(H2O0(SO4)3] - triclinic, IMA 2021-115. Author's material from teh type locality, with a wide range of associated rare species on the better specimens, small fragments to TNs priced according to coverage and associations @ 200.00, 280.00 and one superb sample @ 450.00. List alternates!

IMOGOLITE- Fukaiwa, Nanuma-shi, Tochigi Pref., Japan
Each specimen of this rarity is comprised of beige to tan masses of altered, pumice-like imogolite comprising matrix from this unusual locality. Dull luster and aesthetically challenged (ie. ugly!), pieces are contained in capsules and are from 2mm to 4mm across @ 20.00, 30.00, and 40.00 each depending on size.

JUANITAITE- Gold Hill Mine, Tooele Co., Utah
This relatively rare species occurs as small, yellow-green micro rosettes and druses sparsely scattered in vugs and exposed seams on matrix, some associated with needle-like blue connellite, or fine tyrolite, or occasionally other species. Most of this material was collected on the 150 level over 25 years ago and was subsequently named for its discoverer, the late Juanita Curtis. Modest micro potential as well, matrix sizes from about 2cm to nearly 6cm @ just 40.00, 65.00, 85.00 and 100.00 each, depending on quality/size.

JUANITE with CEBOLLITE- Iron Hill, Gunnison Co., Colorado
From the type locality for both species, acquired from Forrest Cureton in 1987, each of these rarities occur as white to pale greenish submicroscopic, fibrous aggregates sparsely scattered in uncompahgrite rock, typically with melilite, perovskite, pyroxenes and other ugly species. Both are difficult to distinguish or observe unless a thin section is prepared, and both are grandfathered but questionable species today. Specimens from about 1.5cm to 4cm across @ 20.00, 35.00 and 50.00 each. Limited stock!

KLEBERITE- Konigshain-Wiederau, Saxony, Germnay
A moderately rare mineral with only four known localities, of which all are considered cotypes for the species. It
occurs in alluvial sands as minute red-brown to brown grains, an apparent alteration product of ilmenite. First
published in 1960 but not IMA approved until 2012 after further study. Ex-Cureton material, a few tiny grains in a
vial @ 25.00 each.

LEIGHTONITE- Chuquicamata, Chile
Pale blue to blue-green aggregates of this rare species occurring as seams or patches running through matrix or
as nicely exposed, rich crystalline aggregates protruding from rock, occasionally with minor atacamite. Old material no longer available on the market, lean material in matrix sizes from 2.5cm to 5cm @ 15.00, 25.00, and 35.00 each; also superbly rich samples from 3cm to 7cm @ 50.00, 75.00, 125.00, 250.00, and 375.00 depending on quality and degree of crystallization.

LEONARDSENITE- Valvassera Mine, Varese, Lombardy, Italy
A moderately rare halide that often escapes detection, leonardsenite occurs here as very tiny, white pseudo-
octahedral crystals scattered on matrix. Approved in 2011, the mineral was first described from Iceland, but this locality is the most recently described with crystallized samples. Only one 2.5cm specimen available @ 275.00. List
alternates!

MADEIRAITE (IMA2021-077) - Terra do Baptista, Madeira Island, Portugal
This new species occurs as minute, slender and elongated yellow crystals in vugs in analcime-rich, gabbro matrix.
Formula: Na2Ca2Fe2Zr2(Si2O7)2O2F2 - monoclinic, IMA 2021-077. A new member of the wohlerite group, and possibly the Fe-analog of lavenite. A small TN specimen about 1.5cm across with our arrow @ 295.00 with decent
micro potential as well. List alternates!

MAGNANELLIITE (IMA2019-010) - Monte Arsiccio Mine, Tuscany, Italy
This new species occurs as micro, yellow to yellowish orange vitreous crystals in vugs, typically associated with
alum-(K) and possibly other species. From the type locality which has produced nine other new minerals, these are moderately attractive under the 'scope. Formula: K3Fe3+2(SO4)4(OH)(H2O)2, monoclinic, IMA2019-010. Only a few 2.5cm specimens on hand @ 95.00 each. List alternates!

MCGOVERNITE- Sterling Mine, Ogdensburg, New Jersey
A manganese silicate arsenate, mcgovernite occurs as brassy submetallic micaceous flakes and aggregates scattered on exposed seams of typical franklinite-willemite-zincite-calcite ore material. Small but relatively rich specimens, 1cm to 3.5cm @ only 20.00, 35.00, and 55.00 each, depending on coverage and size, and one superb, rich 12x8cm cabinet specimen @ 295.00. List alternates!

PEKOVITE- Dara-i-Pioz, Alaiskii range, Tadjikistan
This rare species occurs as minute colorless grains in matrix, these in prepared 2cm probe mounts and accompanied by at least one SEM image and an X-ray spectra. The formula: SrB2Si2O8, the Sr-analog of danburite and maleevite, named for prolific Russian mineralogist and author Igor V. Pekov. IMA2003-035, type locality material and author's studied specimens, only a few available @ 155.00 each.

PHARMACOSIDERITE- Copper Stope, Majuba Hill, Pershing Co., Nevada
From the an old hoard, we have a few rather fine pharmacosiderite specimens that show excellent micro green cubes of the mineral nicely scattered in exposed seams and vugs. All are quite attractive under the 'scope, and some of the better samples may be associated with other species as well. We have only a few of these, all with good micro potential, sizes from 2cm to 6cm @ 10.00, 25.00 and 45.00 each, depending on quality and size.

QUARTZ (Smoky), MICROCLINE etc- Hurricane Mt., N. Conway, Carroll Co New Ha
Coarse granitic matrix comprised primarily of microcline, quartz and minor mica shows small, terminated smoky quartz crystals to 1 cm lightly scattered over typically crystallized feldspar. Collected in 1965, the material has occasionally yielded micro zircons, astrophyllite, assorted amphiboles and other species upon trimming. Specimens range from about 3cm to 7cm across at just 5.00, 12.50 and 20.00 each, all with small terminated smokies.

QUARTZ var: AMETHYST- Guanajuato Municiality, Gto., Mexico
airly large specimens of delicate, amethystine-hued quartz in small crystals and druses fully covering one surface of
these older, silica-rich matrix specimens. Originally in the stock of Hamel Mining & Minerals circa 1970s vintage, and recently unearthed here, these are colorful but not spectacular, overall sizes average 10 cm across @ just 20.00 each, cheaper than the more common Brazilian material.

QUARTZ w/ TOURMALINE inclusions- Jenipapo Distrist, Itinga, M.G., Brazil
Unusual, fine-grained massive blue quartz comprising matrix. The bluish color is teh result of minute tourmaline
inclusions (we believe olenite rather than elbaite), but we are unable to properly quantify or differentiate the two via
EDS alone. A tough and durable material, likely suitable for lapidary work, and the very tiny crystals can often be
seen under 40x magnification. Specimens from small 2.5cm pieces to chunky 8cm hand samples at just 7.50, 20.00
and 40.00 each.

SCOLECITE- Arkaroola, Flinders Ranges, S.A., Australia
A small lot of white, elongated fibrous scolecite, closely packed and intergrown in matrix, occasionally with minor
stilbite. This material was originally labelled as pectolite (which it absolutely resembles), and it laid unnocticed in
our warehouse for decades. We recently ran a quick EDS analysis and confirmed that it is, indeed, scolecite, and in
an interesting pectolite-like habit. Specimens from 2.5cm to 5cm across @ just 10.00, 20.00 and 35.00, each
accompanied by a copy of our analytical work. Neat locality material!

SELENIUM- Homestake Mine, Ambrosia Lake Dist. New Mexico
Native selenium occurs as dull greyish, somewhat fibrous masses scattered in and on sandstone matrix. From one of the more prolific localities in the Poison Springs area, we have matrix specimens from about 2cm to nearly 5cm
across @ 35.00, 45.00, 60.00 and 75.00 each, priced according to richness, not size.

SILLIMANITE w/ GARNET in GNEISS- Deep River, Middlesex Co., Connecticut
A very old specimen, ex-Michigan College of Mines (1897-1927) from this obscure locality. here as a gneissic hand
specimen with tiny garnets and minute, greyish, elongated or convoluted sillimanite sparsely scattered throughout.
Two old labels accompany the piece, otherwise ugly, 8x6cm @ 55.00. One only! Mindat does not list sillimanite from the locality, and we can see why!

SULFUR in DRILL CORE- Freeport Sulfur Co., South Island, New Zealand
An old and rather beat up large-diameter drill core section, measuring about 11cm (~4+ inches) across, showing
thick masses of yellow sulfur veins running through a greyish, argillaceous matrix. A painted label on one edge
specifies "Freeport Sulfur Co. Lake..." "Misc Core" dating the specimen circa 1912-1971. The Taupo geothermal
area on NW South Island is the likely source(?) of the specimen, and an unidentified label with the specimen cited
"Nelson, New Zealand" as the locality. Nelson is a large city NE of the Taupo fields and is probably a label of convenience, not the actual locality for the sulfur-rich drill core. Freeport Sulfur eventually became part of the mega-
miner, Freeport-McMoran that gobbled up Phelps-Dodge and others. In any case, an interesting if rather ugly core section, about 11x10x4 cm @ 55.00. One only.

TINCALCONITE pseudo @ BORAX- New Pit, Boron, Kern Co., California
Old material supplied many years ago by mine manager Jim Minette, these are solid white masses of tincalconite that have replaced borax, some better samples showing borax morphology as well. Specimens are quite pure, sizes ranging from 1.5cm to nearly 5cm across @ 10.00, 20.00, 35.00 and 45.00 each, depending on quality.

TREMOLITE with CHRYSOTILE- Easton, Northampton Co., Pennsylvania
Greyish white, somewhat brittle tremolite comprising matrix, typically with intergrown, fibrous chrysotile. These samples are likely from the Chestnut Hill area to the north of Easton, and specimens are typically stiff, elongated
aggregates from 2.5cm to 7cm long @ just 7.50, 15.00 and 25.00 each.

TURQUOISE- Los Cerrillos, Santa Fe Co., New Mexico
Wonderful "robin's-egg blue" massive turquoise nicely comprising matrix, typically with little or no trachyte rock matrix from this classic locality. These are from small opened nodules, revealing their pleasing color. Ex-Michigan College of Mines material, specimens measure from 1.5cm to 2.5cm across @ just 12.50 and 20.00 each. Difficult to get the real "stuff" these days.

VANADINITE (ex-Stilwell)- Unspecifed locality, Arizona
An historically interesting specimen that shows small, multiple barrel-shaped crystals of deep red vanadinite on matrix. At the bottom of the piece is a small adhered label from L.W.. Stilwell, a mineral dealer in Deadwood, Dakota Territory circa 1883-1889. The specimen is ex-J.T. Reeder (1857-1937) purchasing agent for the Osceloa and Tamarack copper mines who stored his collection in a windowless brick addition to his dining room, secured by a bank vault door! The collection later came to the A.E. Seaman Museum (their label included), and this old specimen with fine provenance measures 5 cm across @ 55.00. One only!

WENDWILSONITE- Aghbar, Zagora Prov., Draa-Tafilalet Morocco
Attractive, deep red-purple, stout crystals to 4mm of wendwilsonite richly scattered in an exposed seam in matrix,
Excellent coverage and a copy of our confirming analytical work is included. The Mg-analog of roselite, gemmy and
colorful, overall sizes about 3.5cm to 4cm across @ 350.00. Excellent, confirmed material!

XOCOMECATLITE with MCALPINEITE- Centennial Eureka Mine, Juab Co., Utah
Excellent, micro green balls of this uncommon species, beautified scattered on clear quartz druses in an exposed seam in matrix, accompanied by thin films of yellowish-green mcalpineite. Ex-Jensen collection, from the material XRD confirmed by Andy Roberts used in the description of mcalpineite found here. Only one excellent TN available with fine micro potential, overall size about 2.5cm tall @ 395.00.

ZANAZZIITE- Lavra da Ihla, Itinga, Minas Gerais Brazil
This unusual phosphate occurs as greyish-green balls to several millimeters perched on matrix, typically associated
with well-formed micro eosphorite crystals and occasionally other species such as wardite, collinsite etc. Type locality material with modest micro potential as well, overall sizes from 1.8cm to nearly 3cm @ just 30.00, 45.00 and 60.00 each, all ex-Luis Menezes.

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 crystals extend to 6mm across, and they are highly lustrous against the dull, greyish rhyolite porphyry matrix, some with associated scorodite as well. These were 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 9cm, priced according to quality @ 15.00, 30.00, 45.00 and 65.00 each, some with good micro potential as well!

CATALOG 22204 – Volume 49, No. 4

AEGIRINE etc.- Laven Island, Langesundfjorden, Norway
This prolific pyroxene occurs here as dark greenish to nearly black elongated crystal sections frozen in
nepheline/feldspar matrix, occasionally with other species present. Much of our material was collected by E.W.
Heinrich, famous geologist and mineralogist who travelled the world. The white matrix often brightly fluorescent (red SW UV), and a copy of Heinrich's label accompanies each specimen. Sizes range from about 4cm to 8cm across at just 10.00, 20.00 and 35.00 each.

ARSENTSUMEBITE- Ten Strike Mine, Klondyke, Graham Co., Arizona
A long story about this find will appear in Mineral News soon. Suffice to say that it is analyzed material (a copy of
our analysis accompanies each sample), and the mineral occurs as micro green botryoids scattered on matrix.
There is modest micro potential here, and the samples are from just the second reported occurrence in Arizona.
Specimen sizes range from about 3cm to 7cm across with varying coverage, priced at just 15.00, 25.00 and
45.00 each.

BOTALLACKITE- Santo Domingo Mine, Tocopilla, Chile
From an older find (2007) in this Antofagasta Province copper locality, botallackite occurs here as pale greenish
blue radiating aggregates and sheaf-like micro crystals sparsely scattered on matrix. Requires some magnification
to appreciate, but these are among the first (?) botallackite specimens confirmed from a South American locality,
and happily, they are not a slag mineral here! Sizes range from 2cm to 4cm @ only 15.00, 25.00 and 40.00 each.

CALCITE- Sampson Mine, St. Andreasberg,Saxony Germany
An excellent TN specimen displaying a sharp, distinctly hexagonal single crystal without matrix with transparent to
translucent clarity. The pinacoid termination is opaque white, and the prism faces are lustrous and sharp, with a
rhombohedral cleavage line evident on two faces. The specimen was originally acquired from Dr. Hail Sarp in 2003
at the Natural History Museum in Geneva, Switzerland, accompanied by a very old label. Ex-Jensen Collection,
attractive, underpriced @ 325.00. One only!

CALCITE in MARBLE- Tate, Pickens Co., Georgia
A couple of old, interior marble samples, one surface fully polished with beveled edges, the reverse side with
adhered labels from "Geo. B. Sickels & Co.", finishers of Georgia Marbles. The company was apparently bought
out in 1916-1917, suggesting the vintage of the pieces. The fairly large samples are ex-E.W. Heinrich, famous
geologist and mineralogist, and they are accompanied by his labels as well. Each polished sample measures
about 19x9x0.7cm @ 35.00 each, and all have a broken corner. Interesting historical artifacts of the Georgia marble industry from Heinrich's extensive collections.

CARYOCHROITE- Umbozero Mine, Alluaiv Mt., Kola, Russia
Another relatively rare species from the Lovozero Massif, here as nearly monomineral masses of this dark brown,
nafertisite-like material, some with long slender embedded elpidite crystals. From the type locality in the Elpiditivoye pegmatite, formula: (Na,Sr)3(Fe3+,Mg)10[Ti2Si12O37](O,OH)9*8H2O.

List alternates!

CHERALITE- Uranium King Mine, Encampment, Wyoming
Nearly pure masses of multicolored buff to dark brown cheralite. This Carbon County occurance is quite different
from the type locality in India, and these are opaque masses of this complex, thorium rich phosphate. Rarely
available, sizes from 1cm to 6cm @ 15.00, 30.00, 50.00, and 75.00.

CHILDRENITE- George & Charlotte Mine, Devon, England
Minute crystals of resinous, brick red childrenite partially coat 4mm quartz crystals on ore specimens from this
Tavistock area mine, the type locality for the species! Excellent older material with modest micro potential as well,
sizes range from about 2cm to 5cm @ 15.00, 30.00 and 45.00 each.

CHLORARGYRITE- Broken Hill, New South Wales, Australia
A dendrititic greyish mass of chlorargyrite from the classic locality! The chlorargyrite forms either solid lattice-works, or small yellowish crystals on coronadite/limonitic matrix, most with typical dark olive green and metallic grey luster. Exceptioanlly rich samples, sizes from 1.5cm to 6cm @ 40.00, 75.00 and 150.00 each. Only a few on hand - list alternates, please!

locality for the species. Old Cureton stock, only a few small samples available from 3mm to 6mm @ 20.00 and
35.00 each, one larger matrix sample 2.5cm @ 125.00.

ELYITE etc.- Redmond Mine, Haywood Co., North Carolina
Pale purple, tiny tufted sprays and fibers of elyite scattered in ore matrix, most associated with white needles of
sidpietersite or tabular bechererite crystals. All samples have arrows pinpointing the micro sprays, overall sizes
averaging about 1.5 cm across @ 100.00, 125.00 and 150.00 each, depending on associations and coverage, all
with modest micro potential as well.

EMELEUSITE- Igdlutalik, Greenland
This rare species occurs as minute transparent to buff colored drusy crystals nicely scattered in matrix. A rare Na-Li-Fe silicate and member of the osumilite group. Classic locality and rarely available fro sale, sizes range from 1cm to 1.5cm @ 55.00 and 75.00 each.

ERYTHRITE- Santa Alicia Mine, Alamos, Sonora, Mexico
Rich magenta needles and tufted sprays of erythrite scattered on matrix in mine run quality. From the classic
Mexican locality, these are nicely sized and potentially make good micros as well. Quite colorful, matrix sizes from
3cm to 5cm @ 10.00, 15.00 and 25.00 each based on coverage/quality.

FASSINAITE- Redmond Mine, Haywood Co., North Carolina
Tiny white to colorless crystal groups and sprays of this rare lead thiosulfate-carbonate mineral perched in exposed vugs on ore matrix. Each specimen is in a 2.5x2cm box with an arrow pinpointing the species, and overall matrix sizes average about 2cm across @ 125.00 each. Only the second known U.S. occurrence for the mineral!

GANTERITE- Isenwegg, Ganter Valley, Valais, Switzerland

specimen, about 1cm across @ 85.00. List alternates!

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 porcelaneous 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 15.00, 25.00 and 40.00 each.

GOETHITE included AMETHYST- Ametista do Sul, Rio Grande do Sul, Brazil
Pale amethyst quartz crysdtals richly covering matrix, these with excellent, micro sprays and tufts of golden to
brown goethite scattered in the transparent quartz. Older material and suitable for trimming and fine micromounts, some of the larger samples with underlying, pale bluish-grey chalcedony, all inexpensively offered in sizes from about 3cm to 7cm across at just 5.00, 10.00 and 15.00 each, depending on inclusion quality and coverage.

HESSITE- Bambollita Mine, Moctezuma, Sonora, Mexico
This uncommon species occurs here as rather finely disseminated greyish grains in white quartz matrix, some
occasionally associated with minor secondary tellurium minerals. Lean specimens but an interesting assemblage
from a well-known deposit, sizes range from about 2cm to nearly 7cm @ 20.00, 35.00, 50.00 and 75.00 each,
depending on coverage.

HETAEROLITE v: HYDROHEATEROLITE- Leadville, Lake Co., Colorado
From an old flat originally supplied by Forrest Cureton many years ago, we have a modest selection of black,
somewhat botryoidal hydrohetaerolite masses richly scattered on matrix, occasionally with aragonite or possibly
other species. The better samples often have a vitreous luster, while most will also have a rather dull, flat black
coating of chalcophanite. Lately considered to be a discredited variety of hetaerolite, there are variations in XRD
results but redefined spinel groupings in 2019 have confirmed its varietal status. Specimens from 2.5cm to 8x5cm
samples are 8.50, 20.00, 35.00 and 55.00 each.

LAZURITE- Cascade Canyon, San Bernadino Co., California
Dark blue masses of granular lapis lazuli bands richly scattered in matrix, typically with tiny specks of pyrite in a
tough, quartzite/limestone matrix. Fairly colorful material, dense chunks about 6cm across @ 35.00 each, or as
large diamond-sawn slabs about 18x12x0.7 cm @ 45.00 each. Limited availability!

LEITEITE- Tsumeb, Otavi, Namibia
Clear, colorless pearly thin cleavage plates and crystalline fibers of this rare Tsumeb mineral, occurring as pure
masses without matrix. Leiteite, from the type locality for the species, is available in 0.5 to 1.5 cm sizes @ 45.00,
75.00 and 125.00 each.

MAGNETITE variety LOADSTONE- Iron Mountain, Iron Co., Utah
Massive magnetite (variety lodestone) that is naturally magnetic occurs here as dark brownish black chunks of ore comprising matrix. Collected by the late Ted Morley in the 1960s, we will even include some iron filings that add some interest to these weird specimens. Sizes from about 3cm to 8cm @ 10.00, 20.00, 30.00 and 45.00 each.
Heavy!

MAHNERTITE- Fenugu Sibiri Mine, Sardinia, Italy
A rare hydrous Na-Cu arsenate-chloride species, here from one of the few confirmed localities. It occurs as excellent, pale blue botryoids well-scattered on matrix, and quite attractive under magnification. Described in 1994 for the late Volker Mahnert of the Swiss Natural; History Museum, only one small (~1cm) micro available @ 145.00.

METAVIVIANITE- Stoneman Camp, Rapid Creek, Y.T., Canada
Deep greenish, tabular aggregates of metavivianite as paramorphs after vivianite, here from a well known and
prolific phosphate mineral locality. The metavivianite occurs as green micaceous nearly pure masses without much matrix, numerous small fragments in a capsule @ 10.00, larger single plates from 1cm to 1.5cm @ 20.00 and 30.00 each. A dimorph of ferrostrunite and isostructural with symplesite.

MUSCOVITE var; DAMOURITE- Halsjoberg, Torsby, Varmland, Sweden
A small lot of these old very old muscovite specimens, noted as the resinous to greasy variety "damourite". All are accompanied by Michigan College of Mines labels, vintage 1897-1927, noted with the former "Horrsjoberg, Wermland" locality, and a few are also with original handwritten Krantz labels with the same designation. Interesting historical locality samples, all relatively ugly, averaging about 5x3 cm @ 25.00 each.

PARATACAMAITE w/ PSEUDOBOLEITE- La Compania Mine, Sierra Gorda, Chile
Interesting micro material consisting of tiny, greenish black paratacamite crystals and aggregates scattered on rock matrix, most with tiny, blue micro crystals and druses of pseudoboleite as well. Both species confirmed in our lab, and copies of X-ray spectra provided. Collected over 15 years ago, matrix sizes range from about 2.5cm to 6cm across at 15.00, 25.00, 45.00 and 65.00 each, depending on coverage and quality.

PYRITE- Merelani Hills, Simanjiro, Manyara, Tanzania
Very unusual single crystals of pyrite showing multiple crystal faces (cube, pyritohedron, octahedron, diploid and/or trapezeohedron and other forms, best described as "pseudo-icosahedral" in habit. Most are matrix-free except for the occasional underlying graphite on some samples, and they are fairly large in size, and all show typical detachments on the underside of each crystal. These range from about 4cm to 5.5cm (!!) single crystals and are very reasonably priced at just 40.00 and 50.00 each depending on quality/size. Very unusual!

PYROLUSITE- Urkut Mine, Csarda Hill, Veszprem, Hungary
Densely packed, rich manganese ore consisting primarily of pyrolusite as minute aggregates and occsionally with black, platy cryptomelane and other Mn-rich species. Uncommonly offered locality specimens in generous sizes averaging about 6cm across at just 20.00 each, collected over 30 years ago.

ROSASITE (NICKELOAN)- Km3 Pit, Lavrion, East Attica, Greece
Some years ago, we dubiously acquired a small lot of "glaukosphaerite" from a German dealer from this prolific
locality. Aware that the species has been largely mis-identified from here, we finally ran the micro green botryoids in our SEM/EDS lab, and as expected, they were confirmed as nickeloan rosasite. So here they are: dark green balls scattered in vugs in matrix, occasionally with micro crystals of smithsonite and/or other species. Decent micro potential if you care to trim these down, specimens from about 3cm to 7cm across at just 10.00, 15.00 and 25.00, each with a copy of our confirming analysis.

ROUAITE on CUPRITE- Tenke Mine, Lualaba, DR Congo
This rare anhydrous copper nitrate species occurs here as minute, delicate bluish crystalline aggregates scattered on deep red cuprite matrix, this sample with green malachite evident as well. Moderately attractive under the microscope, the specimen is 1.7cm long @ 155.00. Only one available.

SCORDARIITE (IMA2019-010)- Monte Arsiccio Mine, Tuscany, Italy
This relatively new species occurs as minute, yellowish to slightly brownish, thin stacked plates, perched in alum-(K) matrix. The mineral has a shape vitreous luster, and other associated species from this prolific locality (70 species, 10 new types) are possible. IMA2019-010, moderately attractive under the 'scope, and all with fine micro potential as well. Sizes average about 2.5cm @ 95.00 each. Limit one per order, please.

SEMSEYITE ps @ PYRRHOTITE etc.- Cavnic (Kapnic), Maramures, Romania
A large and impressive specimen comprised of greyish black, striated semesyite pseudomorphing platy pyrrhotite,
with much crystallized black sphalerite covering the entire specimen. There is minor galena and a central grouping of small white quartz crystals to finish off the piece, and the underside shows some carbonates and thin, very pale pink rhodochrosite bands of little consequence to the overall specimen. Surface size is a generous 15x12 cm @ 350.00. Ex-Dudas Collection. Heavy!

SEPIOLITE variety QUINCYITE- Quincy-sur-Cher, Bourges, France
Very strange, rather stiff but still flexible fibrous masses and curled leathery aggregates of crude, white sepiolite from this classic French locality. Very old material collected many years ago, referenced in Lacroix's Mineralogie de la Francais et de Territoires. Specimens are 1.5cm in a vial @ 10.00, or 5cm to 8cm thick, elongated fibrous masses @ 65.00 and 85.00 each. Very pure, weird stuff!

SIDERITE, MUSCOVITE, RUTILE etc- Rist Mine, Hiddenite, Alexander Co. North
A large cabinet specimen comprised of a 2cm rhombohedral crystal of pale tan, translucent siderite, perched on the edge of a large, scattered grouping of up-standing hexagonal muscovite crystals to 2cm, accompanied by several 1.5cm translucent dolomite crystals, along with minor albite and trace rutile. An attractive mineral group that is an impressive 17cm x 8cm, quite attractive, and just 375.00, its original price when we acquired it over 20 years ago!

STILLWATERITE & MERENSKYITE etc- Fedorovo Pansky Massif, Murmansk, Russia
A remarkably well-documented microprobe study, consisting of four (4) small ore samples, all embedded in a 2.5 cm probe mount. Four (4) different SEM images are provided, each accompanied by one or more detailed microprobe analyses showing both elemental and atomic compositions that confirm stillwaterite, merenskyite, sperrylite and a Pd-rich gersdorffite! One of the last of our comprehensive studies of the Pana layered Habbro-Norite Complex of the Kola Peninsula, only one available @ 450.00.

STURMANITE- N'Chwaning Mines, Kuruman, No. Cape, South Africa
A wonderful cabinet specimen of this uncommon mineral, here as numerous, stout, opaque-yellow hexagonal crystals (the largest 1.5cm long), well scattered on dark, Mn-rich matrix, much of it coated with micro drusy calcite crystals and possibly other species. At one edge, the underlying alteration zone shows dull white micro crystals of an unknown mineral, possibly altered charlesite(?). An interesting and relatively large, older specimen, overall about 16cm x 9cm @ 450.00.

TITANITE- Morafeno, Fianarantsoa Province, Madagascar
An interesting lot of rather large, opaque brown titanite crystals, similar to those seen from Nevada and elsewhere. The crystals are available as individuals or small groups of crystals, singles reaching 5cm on edge, most with minor white matrix and more typically in the 2.5cm size range, and these are rarely complete. All show good prism faces, some interesting twins and intergrowths, most with glassy, minutely pock-marked faces throughout. Interesting specimens, overall sizes from 2cm to 5cm as singles or groups @ 10.00, 20.00, 35.00 and 50.00 depending on quality and size, with singles generally better than groups. Please specify!

TREMOLITE variety HEXAGONITE- nr. Balmat, St. Lawrence Co., New York
Vitreous aggregates and crystal sections of colorful, lilac hexagonite variety of tremolite richly comprising matrix, these collected by G.F. Lincks many years ago. Specimen sizes from 2.5 to 5cm, most relatively flat, @ 7.50, 12.50 and 17.50 each, and all with an attractive, delicate hue. Larger samples up to 16 x 5cm @ 55.00, 65.00 and 75.00 each. Nice!

VANADIOCARPHOLITE- Molinello Mine, Graveglia, Genova, Italy
This rare mineral occurs as minute, beige to golden acicular needle-like crystals perched in thin seams and voids on fossilized wood matrix, typically with pale green volborthite as well. IMA-approved (#2003-055), this is type locality material with good micro potential as well, specimen sizes from 1.2cm to 2cm @ 135.00 each. Only a few available!

WHITLOCKITE- Palermo #1, North Groton, New Hampshire
From one of the early finds at this, the type locality, we have a small lot of rather unappealing, granular white whitlockite scattered in/on matrix comprised largely of quartz and siderite. Specimens range from about 2cm to nearly 6cm across at just 15.00, 25.00 and 45.00 each, a much sought-after type locality phosphate.

ZINKENITE with BERTHIERITE etc.- Sterling Mine, Ogdensburg, Sussex Co New J
A pair of large, greyish calcite masses, each lightly embedded with pale red-orange realgar grains, accompanied by very tiny, thin metallic streamers of elongated berthierite and zinkenite scattered in several areas of each specimen. Occasional platy molybdenite, as well as small masses of arsenopyrite and pyrite, have also been observed in these samples, and the literature reports seligmanite and baumhauerite, which I have not been able to verify as yet. Rare at the locality, sizes from 2.5cm to 6cm @ 45.00, 75.00 and 100.00 each.

A STRANGE THING OR TWO

TEKTITE var: INDOOCHINITE- Khon Kaen Province, Thailand
Weird terrestrial/extraterrestrial natural glass from the prolific tektite belt of the Indochina peninsula that stretches across Southeast Asia. These pitted, dark greenish brown glass nodules appear nearly black, typically with pock-marked exteriors. The two schools of thought about their origin involves either earth material thrust into the atmosphere by large meteorite or asteroid strikes, returning to earth in this melted, flown form, or actual
extraterrestrial projectiles lacking all metal content, some opining that they are lunar in origin. In either case, these oddities are often sold by the gram, but we have a large lot from our meteorite supply days offered here
inexpensively as rounded masses from 2.5 to 3cm @ just 8.50 each, or as odd, elongated, tear-shaped or bar-like
forms to 6cm long @ just 20.00 each.

CATALOG 22203 – Volume 49, No. 3

ALTAITE - Hilltop Mine, Dona Ana Co., New Mexico
This unusual lead-telluride occurs as brilliant metallic streamers scattered through rock matrix, occasionally with
other tellurium minerals. Available as rough matrix samples from 1cm to nearly 6cm across @ 25.00, 45.00, 75.00
and 100.00 each according to coverage; EDS confirmed and copy of analysis supplied!

AZURITE- Peacock Mine, nr. Leadore, Lemhi Co, Idaho
There is much confusion about this obscure locality, not to be confused (and a specimen erroneously pictured from there in Mindat) with a mine of the same name in Adams Co., however. Soon to be featured in an article in Mineral News, we have a small stash of quite fine azurite, either as rich, drusy crystals coating matrix in attractive botryoids, or as striking coatings/replacements of unknown stalactitic precursors. We had two sources for the specimens, both likely collected in the 1950s, as no material has been found on the dumps or elsewhere in many years, perhaps hinting that the locality is actually the nearby Iron Dyke Mine. (However, what is on a dump today does not necessarily reflect what was underground 70 years ago!) Handsome botryoidal specimens averaging about 9x6cm are 200.00 each, and attractive stalactitic specimens range from 6.5cm @ 100.00, and a superb 14x3.5 cm hollow stalactitic piece @ 450.00. Wonderful old stuff; read the story in the next issue of Mineral News!!

BARITE with INCLUSIONS- Regent Mine, Mineral Co., Nevada
Transparent, well-formed, tabular crystals of barite to 1cm nicely scattered on matrix, a few with very sparse, micro inclusions of a fibrous yellow-orange mineral purported to be wakabayashilite. In the past, we have found orpiment, realgar and possibly other species in these included crystals, but we have not destroyed any from this old batch to confirm the literature reports of wakabayashilite which is likely present. Modestly attractive specimens for this common mineral, sizes from TN to nearly 6cm across @ just 7.50, 15.00, 25.00 and 40.00 each.

BISMUTH (Native)- Schneeberg, Saxony, Germany
Old specimens from various collections, going as far back as material acquired from Krantz by the Michigan College of Mines, comprised of dense, massive ore with minute brilliant aggregates of native bismuth well scattered throughout, often associated with nickel-skutterudite masses and possibly minor secondary alterations. A group of representative old classic specimens, sizes from about 3cm to 6cm across @ 15.00, 30.00 and 55.00 each.

CALCITE- Jebel Hafeet, nr. Al Ain, Abu Dhabi, U. A. Emirates
From a highly unusual and never-before reported locality, we have several scalenohedral calcite crystals of
translucent to slightly tan coloration (due to coatings and inclusions), all showing reasonably good crystallographic form. Featured in our Mineral News article in the March, 2022 issue and consequently added to Mindat, singles range from 2cm to 6cm tall @ just 10.00, 20.0-0 and 35.00 each. A few matrix specimens from 8cm across @ 40.00 and 60.00 each. Modest quality but superb locality specimens, likely to never be seen again!

CALOMEL- Cahill Mine, Humboldt Co., Nevada
Like most calomel specimens, these are rather lean, greyish white to slightly yellowish flattened aggregates always associated with minor red cinnabar and occasionally microscopic mercury on matrix. Best located via LW UV fluorescent response, these are old Cureton material collected many years ago, specimens from 2.5 cm to 5cm across @ 35.00, 55.00 and 75.00 each.

CHRYSOBERYL- Carnaiba, nr. Senhor do Bonfim, Brazil
Exceptionally unusual flattened dark greenish-black opaque chrysoberyl sixlings exposed from a dense biotite schist matrix. This is an oddly twinned, matrix free small specimen with several individual crystals to 2cm tall
intergrown on very minor matrix, acquired in 1995 and no longer readily available. These were called alexandrite in the past from this Bahia locality, but in my opinion, the crystals are so dark and opaque that the typical color
change effect of alexandrite is not evident under normally available lighting conditions. Only one good crystal group available, about 2.5 x 2.5cm @ 200.00. List alternates!

CREASEYITE- Mammoth-St. Anthony, nr. Tiger, Arizona
This relative rare species occurs as sparse, pale green crusty aggregates and minutely fibrous masses on matrix,
some associated with punky micro wulfenite and other secondary minerals. From the famous Collins Vein, the
TYPE LOCALITY, specimens range from about 2.5cm to 6cm @ 15.00, 25.00, 40.00 and 55.00 each, depending on quality, some with micro potential as well. Similar material from Gold Point, Esmeralda Co., Nevada is also on hand, at same sizes/prices.

CREEDITE- Aguiles Serdan, Chihuahua, Mexico
Water clear to very pale lilac steeply pyramidal crystals and groups of well formed creedite crystals (2mm to 5mm)
perched on matrix, some associated with minor sphalerite, gypsum etc. Excellent, representative specimens
obtained in 1984 from the West Camp (likely Potosi Mine) of this Santa Eulalia find. Group sizes range from 2cm to
about 5cm @ just 12.50, 20.00, 35.00 and 45.00 each. Old stuff from the famous find, most with good micro
potential as well!

CUBOTHIOPLUMBITE (2021-091)- Redmond Mine, Haywood Co., North Carolina
This NEW SPECIES occurs in vugs of massive galena-chalcopyrite-sphalerite and quartz, often with other
secondary lead minerals. The mineral forms very tiny, pale yellow equant crystals with adamantine luster, formula:
[Pb4(OH)4]Pb(S2O3)3, cubic, IMA # 2021-091, one of several new thiosulfates found at the locality. Author's
material with modest micro potential at high magnification (40x and up), only two small thumbnails on hand @
350.00 each. List alternates!

CUPRITE with CHALCOALUMITE- Lavender Pit, Bisbee, Cochise Co., Arizona
An old specimen, ex-mineral dealer H. Rozenbroek, of a classic, rich cuprite specimen from Bisbee! The cuprite
forms reddish-black crude crystals and aggregates richly comprising much of this heavy specimen, with pale
bluish-green chalcoalumite masses filling many voids in the convoluted surface of the piece. This monster
specimen weighs over a kilo and measures about 11x10x5 cm, low-priced at just 325.00. One only!

DIAMOND- Dudno Region, Lunda Province, Angola
These transparent to translucent octahedral floater crystals of colorless to very pale brown, fully transparent
diamonds come from a great locality. Complete crystals, most having slightly rounded edges and possibly some
etching on the faces under magnification. An uncommon locality that is rarely offered today, sizes from about 2mm to 3mm across for just 20.00 and 25.00 each, or a lot of 3 different crystals for just 65.00.

DIAMOND (FL)- Premier Mine, nr. Pretoria, Guateng, Rep So Africa
Small but perfectly clear, gemmy octahedrons without matrix, most in the 7 to 10 point size range, averaging about 2x2mm in size. While about 20% to 30% of diamonds may show some fluorescence, it is fairly unusual property that is not easily observed in many cases. These are brightly fluorescent (blue white) and were hand-picked many years ago by David New in Antwerp. We have a few on hand from this famous locality at just 30.00 each, limit 2 per order, please.

EDDAVIDITE (IMA 2018-010)- Southwest Mine, Bisbee, Cochise Co., Arizona
We have analyzed a number of old specimens from this locality in our inventory, finding a handful of confirmed
eddavidite samples as micro crystals perched on a gossan matrix, some with trace malachite, minor calcite or other species. The mineral occurs as tiny, very sharp, black cubic crystals well-scattered on matrix, some with octahedral modifications seen under the SEM. Formula: Pb2Cu12O15Br2, isometric, IMA 2018-010, the Br analog of murdochite. Each specimen is accompanied by our confirming Br>Cl analysis, specimens from about 3cm to 9cm across @ 45.00, 75.00, 125.00 and 200.00 each.

ELBAITE var: RUBELLITE- Kamdesh Distist, Nuristan, Afghanistan
Small single crystals of pale pink elbaite (variety rubellite) without matrix, all quite transparent, singly terminated, with good prism faces as well. The color tends to darken slightly closer to the termination. Possibly from the Paprok locality, but this older lot was simply noted as "Kamdesh, Nuristan". Moderately attractive single crystals, sizes range from 1.5 to 2cm @ 30.00 and 35.00 each.

FERRORHODONITE- Broken Hill, N.S.W., Australia
This relatively new species was approved in 2016 and represents the Fe-rich mineral in the rhodonite group. We
have had samples on hand from the type locality for some time, but only recently have we analyzed and confirmed
the Fe content that matches the approved mineral. Specimens are relatively pure cleavages of a pleasing pinkish-
red hue, sizes ranging from about 2cm to 4cm across, all supplied with a copy of our confirming analytical data, at
just 30.00, 45.00 and 65.00 each.

FRANCEVILLITE- Mounana Mine, nr. Franceville, Gabon
From the type locality for teh species, this uncommon uranium mineral occurs as minute platelets and aggregates
well-scattered over matrix, possibly with other, undistinguished radioactive species as well. A modest specimen
representative for the mineral, moderately hot, overall size about 5x3cm @ 225.00. One only.

GOLD- Edie Creek, nr. Wau, Morobe Province, Papua New Guinea
We stumbled across a small lot of small gold specimens among material from Hatfield Goudey's (goudeyite) stock.
The mines here operated extensively in the 1920s and 1930s, dwindling thereafter, and the small, relatively pure
specimens are flattened and alluvial, most averaging 5 to 9 mm in length. and all are matrix free. Great locality stuff at just 40.00 and 65.00 each, and gold values are climbing!

GOYAZITE- Lengenbach Q., Binntal, Valais, Switzerland
Sharp, nearly transparent microcrystals of orange-brown goyazite are scattered on a typical, sugary dolomititic
Lengenbach matrix. Often distinguished by the pinkish-amber to orange color, goyazite may be associated with
barite, sphalerite, rarely dravite, or the usual assortment of sulfides. From the Bern Museum of Natural History, only two specimens available, sizes average 6x4cm @ 150.00 each, both with good micro potential.

HEXATHIOPLUMBITE (2021-092)- Redmond Mine, Haywood Co., North Carolina
Another new thiosulfate mineral from this uncommon locality, here in small TN matrix sizes, as tiny, colorless,
hemimorphic hexagonal prisms with high luster on ore matrix. Formula: [Pb4(OH)4]PbS2O3)3, hexagonal, IMA
2021-092, a dimorph of cubothioplumbite. Authors material, only two small samples available @ 375.00, and one
@ 450.00.

HYDROREDMONDITE (2021-073)- Redmond Mine, Haywood Co., North Carolina
This NEW SPECIES occurs as transparent, adamantine micro druses and prismatic to bladed crystals in vugs
within a granular galena-sphalerite-chalcopyrite ore. Formula: [Pb8O2Zn(OH)6](S2O3)4*2H2O, monoclinic, IMA
2021-073. The mineral is a new structural type, Strunz 7.JA, thiosulfates of Pb). There are 14 other potential new
species at this, the type locality! Author's material, all with arrows and modest micro potential, overall sizes from
1.5cm to 3cm across @ 125.00, 175.00, 250.00 and 325.00, based on quality and associations.

KRENNERITE- Ajax Mine, Cripple Creek, Teller Co Colorado
Masses and occasional micro striated crystal sections of krennerite are moderately distributed through the typical purple fluorite and quartz matrix for which this district is known, now hard to obtain as most of this rich ore material went to the crusher. Not especially rich, but good representative samples from this famous area. Possibly associated with other tellurides and/or pyrite, sizes from 1cm to 4cm @ 25.00, 50.00, 75.00 and 95.00 each, depending on richness.

MALACHITE etc. (polished)- Likasi, Kambove, Haut-Katanga, DR Congo
Our last African shipment contained a good lot of well-polished, somewhat flat, botryoidal malachite specimens.
These are surprisingly attractive, with concentric bands, eyes, convoluted rings etc, all beautifully polished and
occasionally with minor blue chrysocolla in matrix sizes from about 4cm to 8cm across at just 15.00, 25.00, 35.00
and 45.00 each. Colorful and very nice display specimens!

MUSCOVITE crystals!- Hiddenite, Alexander Co., North Carolina
Excellent crystals of elongated, columnar, hexagonal muscovite to 5mm well scattered in groups and comprising
matrix, many showing modest transparency and superb form under the scope! From an old stash of Hamel Mining
& Minerals stock, these are inexpensive TNs and excellent for the species, most wil fine micro potential as well.
Sizes average 2.5cm across at just 7.50 each!

NIKSERGIEVITE- Tekeli Pb-Zn Mine, Almaty Region, Kazakhstan
This relatively rare species occurs as monomineralic grains and platy aggregates averaging about 1mm across,
somewhat pearly white in luster and color. Formula: (Ba,Ca)2Al3(Si,Al)4O10(CO3)(OH)6*nH2O - monoclinic. Author's studied material from the type (and only) locality for the species, IMA #2002-036, only a few boxed grains
available @ 125.00 each.

POUGHITE- Bambollita Mine, Moctezuma, Sonora, Mexico
Dull yellowish to tan masses of this relatively ugly species scattered on matrix, occasionally with other secondary
tellurium minerals. From a recently uncovered old lot, matrix sizes from lower grade 2cm pieces to richer 6cm
pieces @ 25.00, 40.00, 65.00 and 100.00 each, each with a photocopy of Fred Pough's original label. How he
hated the mineral for being so ugly he once told me!

QUARTZ var: Blue Chalcedony- Ngabu Village, Chikwawa, Malawi
From an off-beat locality, we have a few, pale blue chalcedony geode-like formations that have small, drusy quartz
crystals perched in their centers, surrounded by the bluish agate. Fairly attractive and relatively cheap from this
weird locality. Sizes average about 3cm to 5cm across @ just 10.00, 15.00 and 20.00 each. Moderately attractive!

QUARTZ variety JASPER- East Java Province, Indonesia
We recently acquired whole nodules of jasper from this unusual locality, and subsequent slicing and gentle
polishing shows moderately colorful bands of tan, brown, grey, yellow and pinkish hues throughout. We offer matched pairs of lightly polished nodules, ranging in size from about 6x5cm to 8x6cm surfaces, generally weighing from about 300 grams to nearly a kilo per pair, priced at just 25.00, 35.00, 50.00 and 65.00 per matched pair, depending on size and quality!

SANBORNITE- Esquire #1 Mi., Rush Crk, Fresno Co California
Rich, pearly masses of nearly pure, translucent platy sanbornite comprising matrix. Collected over fifty years ago,
these are exceptionally rich specimens, overall sizes ranging from about 2.5cm to 6cm @ just 10.00, 20.00, 45.00
and 65.00 each.

SELENIUM- Desert Peak, Churchill Co., Nevada
Dull, earthy masses of greyish to brownish minute masses of native selenium very sparsely scattered on matrix.
Truly ugly but from an uncommon locality. Ex-Cureton, specimens from about 1.5cm to 3cm across @ 15.00, 30.00
and 45.00 each.

SPESSARTINE- Slagle Mine, Franklin-Sylva District, North Carolina
This Macon County locality consisted of a number of Slagle prospects detailed in the 1968 USGS Professional
Paper 577, contributed to by E.W. Heinrich and others. These garnet specimens were his (copy of label supplied
and our confirming analysis as well), and the samples are being written up in an April, 2022 article in Mineral News. They occur as sharp, dark brown crystal faces and intergrown sections protruding from matrix, and the locality is certainly an old and obscure one, likely collected by Heinrich as part of his survey work for both USGS PP 577 and his own American Mineralogist article (Vol. 50, October, pg 1765). Only three specimens available, sizes from 3.5cm to 4cm across @ 55.00 each, about the cost of our analytical work!

SPHAEROBERTRANDITE- Senigschorr Mt., Lovozero Massif, Russia
This valid species is offered as small spherules and micro disk-shaped radiating clusters within epididymite matrix,
occasionally with micro crystalized epididymite as well! Formula: Be3SiO4(OH)2, monoclinic, P21/C, first described
in 1957 but ruled by the IMA hierarchy as a valid species in 2003. These are neotype specimens, sizes range from
about 2cm to 3cm @ 100.00, 125.00 and 150.00 each, depending on quality. Only a few available!

STIBNITE- Post/Betze Mine, Eureka Co., Nevada
Fine, steely grey elongated needle-like crystals and aggregates of stibnite in vugs and as free-standing groups on
rock, some with platy, transparent barite crystals as well. An interesting find from about 25 years ago, most with
micro potential as well, matrix sizes from 2cm to 7cm @ 10.00, 20.00, 35.00 and 55.00 each.

STICHTITE- Stichtite Hill, Dundas, Zeehan Dist. Tasmania
Rich, deep lilac-purple masses of stichtite generously scattered throughout matrix, most with minor green
serpentine in association. Very colorful, classic material, collected by Forrest Cureton many years ago from the
type locality! Matrix sizes from 2.5cm to 6cm @ 12.50, 20.00, 30.00 and 45.00 each. A few larger - please inquire!

SULFATOREDMONDITE (2021-089)- Redmond Mine, Haywood Co., North Carolina
Yet another NEW SPCIES from this chemically-weird locality, here as tiny wedge-shaped and stout colorless
prisims with adamantine luster in sulfide/quartz matrix. Formula: [Pb8O2Zn(OH)6](SO4)4*6H2O, monoclinic, IMA #
2021-089. Author's material with modest micro potential, occasionally with other secondary species @ 150.00,
200.00 and one @ 300.00.

SYNCHYSITE-(Y) (DOVERITE)- Scrub Oaks Mine, nr Dover, Morris Co New Jersey
Dark brick red masses of synchysite-(y) speckle a matrix of dark greyish black magnetite ore on these massive
granular samples from the type locality. The mineral was originally called "doverite" due to the Mine Hill Borough's
proximity to the adjacent town of Dover. Collected by yours truly over 40 years ago while residing nearby! Sizes
from 2cm to 6cm @ 10.00, 15.00, 30.00, and 45.00. A few larger samples available to 15cm @ 85.00. Impossible to find this type locality material today!

TELLURIUM etc.- Moctezuma, Sonora, Mexico
Silvery-grey masses and tiny platy aggregates of native tellurium scattered in matrix, some with lightly associated
films of chalky tellurite/paratellurite on matrix. At one time, the material was abundant, but availability has declined considerably in recent years. Over 80 different species occur here, including 16 type species, and rarities may be found in unanlayzed matrix samples! Specimens from 2cm to 8cm across @ 20.00, 35.00, 55.00 and 75.00 each, depending on coverage and size.

TOPAZ (>3160 cts)- Dassu, Skardu, Gilgit-Baltistan, Pakistan
A large, pale sherry-colored single crystal of topaz, showing major pyramidal faces and little in the way of prisms,
resulting in a rather squat, chisel-shaped crystal with sharp, excellent modifications! Color deepens from top to
bottom of the crystal, but it is transparent and vitreous throughout, showing contact points on the base and rear of the specimen. It resembles Goldschmidt's topaz diagram No. 207 in general form, and the specimen weighs in
excess of 3160 carats, measuring 7x7x6 cm @ 1250.00. Attractive and gemmy; one only!

TSUMOITE- Sylvanite District, Hidalgo Co., New Mexico
Tiny microscopic silvery grains and submicroscopic inclusions scattered in quartz matrix of this rare bismuth
telluride, originally found here (labelled as "near Hachita") by the late Dr. Sidney Williams. Later, the locality was
listed by Bideaux et al simply as "Sylvanite". Lean specimens with sizes from 1.5cm to 3cm @ 35.00, 50.00 and
75.00 each. List alternates!

VLASOVITE in EUDIALYTE- Kipawa Complex, Villedieu, Quebec, Canada
The last of this significantly fluorescent mineral, occurring as relatively large, tan colored pods to 1.3cm across
scattered in bright pink, attractive eudialyte matrix. The vlasovite shows an excellent cream colored fluorescence
under SW UV, and these representative samples range from 2cm to 3.5cm @ 20.00, 30.00 and 45.00 each. A very
few larger samples in feldspar to 125.00 are on hand; please inquire!

WILLEMITE (xls)- Sterling Hill, Ogdensburg, Sussex Co New Jersey
An old lot of curious willemite crystals, originally obtained from Frank Z. Edwards in 1964. Their color is best
described as greyish brown, pale tan in thin section, and all are brightly fluorescent. The crystal habit is crudely
pyramidal, typically with rounded edges, and just really odd for the mineral. Matrix-free, sizes range from 1.2cm to
2.5cm tall @ just 8.50, 12.50 and 25.00 each, depending on habit and size. Strange stuff!

YARROWITE w/ SPIONKOPITE- Yarrow Creek, Alberta, Canada
Type locality for this species and the associated spionkopite, both copper sulfides, spionkopite and yarrowite occur as intermixed dark blue to black metallic grains thickly scattered through quartzite rock, with secondary copper minerals in evidence. Representative, rare type locality material, from 1.5cm to 5cm @ 25.00, 40.00, 60.00 and 85.00 each, depending on size and coverage.

YAVAPAIITE- United Verde Mi, Jerome, Yavapai Co Arizona
Translucent, pale tan to pinkish, very tiny glassy grains of this unusual species admixed with minor rock in a tiny vial. From the mine fire reported to have begun in 1894, this material was originally supplied by Scott Williams from material he collected in 1941 that also yielded the type specimen. Tiny but a rarely offered, a scarce mineral @ 25.00 per vial.

EMPIRE EXHIBITION- in SOUTH AFRICA of 1936
This booklet was a major information source for our Mineral News article in the February, 2022 issue on this well-
known South Africa exhibition in 1936. Rarely found today, the catalogue was prepared by the Transvall Chamber of Mines and provided much detail about the mining exhibitions, dioramas and major works prepared for the event. We have decided to sell our only copy of this rare booklet (32 pages) we had acquired at auction some time ago, and will include a free copy of the Mineral News issue as well, if requested. Size is a compact 18x12 cm and in fine condition, offered at just 55.00 with any mineral order. Very difficult to find today after 86 years!

CATALOG 22202 – Volume 49, No. 2 

AZURITE- Kambove District, Haut-Katanga, Dem Rep Congo 
We recently uncovered a couple of flats of mine-run azurites from this prolific area. After cleaning, we find that they  are deep blue platy masses largely comprising matrix and forming flattened and radiating aggregates, occasionally  with minor malachite or druses of later(?) azurite as well. You'll have to use your ultrasonic cleaners, water guns  and other devices of mineral torture on these, but they are inexpensive as mine-run stock in sizes from 2cm to 5cm  @ at just 10.00, 15.00 and 25.00 each. 

BADDELEYITE- Pocos de Caldas, Minas Gerais, Brazil 
Unusually large masses of nearly pure massive baddeleyite without matrix, here showing typical greyish to  brownish black color and submetallic luster from this prolific locality. Surprisingly heavy for their size, specimen  sizes range from about 2cm to 5cm @ 25.00, 40.00 and 60.00 each. A few larger samples with crude crystal faces  to 6+cm across, ex-E.W. Heinrich @ with his label @ 125.00!

Highly unusual, tiny microscopic inclusions of this Pb-Cu-Bi-S mineral sparsely scattered in clear to greyish-green  fluorite that has been polished to better identify the elongated needles of friedrichite, some with white coatings of  cerussite and occasional chalcopyrite as well. Identification via XRD and EDS at the Canadian Museum of Nature,  only a few specimens on hand, all with arrows, sizes from about 2.5cm to 4cm @ 45.00 and 75.00 each, depending  on number and/or quality of the friedrichite inclusions. 

GILLULYITE- Barrick Gold Mine, Mercur, Utah 
From the Lulu Cut at the South Mercur Pit at this Tooele Co. locality, gillulyite is a relatively rare described thallium  bearing arsenic sulfide mineral, found as deep red crystalline masses sparsely scattered through barite and often  associated with orpiment. Rare and from the type locality, offered as small fragments in a capsule @ 25.00. 

GLADITE- Albigna Glacier, Grishun, Switzerland 
Small greyish black metallic masses of this rare Pb-Cu-Bi-sulfide scattered in quartz matrix, some with minor biotite  in thin seams and sometimes associated with other phases such as bismutite etc. An uncommon mineral, and  microprobe data shows it to be occasionally Fe-rich as well, available in matrix sizes from about 2cm to nearly 6cm  @ 20.00, 45.00, and 75.00 each. 

GOLD (Native)- Arrowtown, Otago Region, New Zealand

We offer multiple small placer nuggets in a vial @ 50.00 per vial,  or larger crystallized nuggets from 1.2cm to 2.0cm across @ 235.00 and 300.00 each. 

KRAUSKOPFITE- Rush Creek, Fresno County, California 
Pearly white to chalky krauskopfite fills seams and forms scales over tan matrix. Best pieces show flattened  acicular development. These are from the type locality for this species, and sizes range from 1.5cm to 5cm @  10.00, 15.00, 25.00, and 40.00 each, depending on size and coverage. 

KYANITE- Karoi District, Mashonaland West, Zimbabwe 
My first kyanite specimens from here were from Dr. Sainfeld (sainfeldite) at the French School of Mines, when the  country was still known as Rhodesia. The kyanite crystals are dark blue and generally opaque, and the habit is  thick and elongated, and quite solid, unlike much Brazilian material. Terminations are indistinct, and the crystal  sections range from about 4cm to 6cm tall at just 15.00 and 20.00 each. Uncommon locality material! 

LIBETHENITE - Lubietova, (Libethen), Banska Bystrica, Slovakia 
Small but well formed crystals of libethenite, deep olive green and glassy, lie scattered and concentrated primarily  in small vuggy areas with quartz. Collected decades ago by a Czech geologist from the type locality for libethenite,  the locality is now known as the Podlipa Deposit. Old material from this historic locality, some associated with minor  secondary minerals, all with good micro potential as well, sizes from 4cm to 8cm @ 25.00, 45.00, and 65.00 each. 
 
LITIDIONITE etc.- Arsenatnaya fumerole, Tolbachik, Kamchatka, Russia 
Russian scientists continue to describe a wealth of new and unusual species from this prolific Kamchatka volcano.  Litidionite occurs here as minute, very pale blue crusts on scoria, typically with tiny, elongated crystals (!!) of  tenorite, minor sylvite and occasionally unidentified mixtures of copper arsenates. Only the third locality in the world  for this rare species, sizes average 1.5cm to 2cm across @ 125.00 each, all with arrows and modest micro  potential. 

MALACHITE (fibrous)- Mindingi Mine, Haut-Katanga, Dem Rep Congo 
As featured in the December, 2018 issue of Mineral News, we have a modest stock of excellent, fibrous malachite  from this exotic locality. A wide range of cross-hatching, densely packed fibrous malachite crystals typifies this  attractive material, occasionally with heterogenite but generally matrix-free. The radiating needles will often show
modest chatoyancy as well, far more interesting the botryoidal material. Specimens range from about 2.5cm to  nearly 8cm across @ 10.00, 25.00, 55.00, 95.00 and 150.00 each. Attractive! 

MEURIGITE-K- Gold Quarry Mine, Eureka Co., Nevada 
Published as one of the four original localities for the species, meurigite from the co-type Gold Quarry is found as  moderate coverage of pale yellow tufts, spheres, and coatings of acicular microcrystals, associated with fluellite,  etc., and was later classified as meurigite-K. There are many associations at the locality, and these make  interesting micromounting material as well. Sizes from 3cm to 8cm @ 25.00, 45.00, and 65.00 each. 

MEURIGITE-Na- Tom's Phosphate Quarry, Kapunda, S.A., Australia 
This interesting species was described in 2007 and occurs here as hemispheres of micro, needle-like crystals in  yellowish balls nicely scattered on brown gossan matrix, accompanied by numerous other phosphate minerals. IMA  #2007-024, the Na-analog of the earlier described meurigite-K. A small selection of moderately rich samples on  hand, matrix sizes from about 3cm to 6cm across @ 45.00, 60.00 and 85.00 each, depending on coverage, and all  with micro potential as well. 

OBERTIITE- Bellerberg, Eifel Mts., Germany 
This rare mineral occurs here at the type locality as pale pink, thin prismatic micro crystals and/or divergent needle like groups perched on matrix. Excellent micro potential on each sample, some with tridymite and other phases, the  verified species has seen little distribution in the commercial market since its approval in 1998. A moderately  unusual amphibole group member, we have several ex-Horvath Collection specimens of superb quality, matrix  sizes ranging from about 7mm to 1cm @ 95.00 each. 

ODINITSOVITE- Koashva Mt., Khibiny, Kola Pen., Russia 
From the second world occurrence for the species, these are unique, monomineralic pinkish, semi-transparent  grains to 1.5mm without matrix, mounted on adhesive tablets in a clear TN box. Found in a single drill core in 2007,  only a few available at just 55.00 each! 

OSAKAITE-LAHNSTEINITE- Redmond Mine, Haywood Co., North Carolina 
Minute, pale green pseudohexagonal plates of osakaite-lahnsteinite are perched in granular galena-sphalerite  ore; this rare assemblage of anhydrous Zn-sulfate hydrates of osakaite-lahnsteinite is dependent on water content,  ranging from 5H2O (osakaite) to 3H2O (lahnsteinite) at the locality. Their occurrence here is rare, and both species  are visually indistinguishable. Only a few 2cm to 2.5cm specimens are available at 75.00 and 125.00 each. List  alternates! 

PARATOBERMORITE (IMA 2020-100)- Southern Pit, Bazhenovskoe, Asbest, Russia  This NEW SPECIES occurs as tiny, colorless to white prismatic crystals richly scattered on colorless  grossular/prehnite matrix. Unlike other tobermorite-group minerals, these are visible, well terminated crystals!  Formula: Ca4(Al0.5Si0.5)2Si4O16()H)*2H2O*(Ca3H2O), monoclinic, IMA No. 2020-100. Small TNs from the type  locality @ 150.00 each, all with good micro potential as well! 

PARGASITE- Pargas, Southwest Finland, Finalnd 
Old specimens from the type locality for the species, pargasite occurs here as greenish black small crystals frozen  in marble matrix. We have two grades of specimens, either as 4-7cm samples with pargasite shot through matrix @  20.00, 35.00 and 50.00 each, or as superb, old classic material consisting of stout pargasite crystals comprising  matrix, smallest groups with 2cm to 4cm crystals(!!), up to monsters of 8cm matrix specimens! All well-formed, ex E.W. Heinrich material noted as "Simonby, Pargas" sizes range from about 4cm to 8cm @ 150.00 and 225.00  each, depending on crystallization. 

PECTOLITE- Snake Hill, Secaucus, Hudson Co., New Jersey 
An interesting specimen, collected in October, 1977 from the extant cliffs at the time from this Laurel Hill locality.  Pectolite occurs here as broard sprays of white crystals richly scattered in both diabase and metamrphosed  sedimentary matrix, this sample ex-H.E. Moore Collection and moderately attractive for the locality. The pectolite  sprays are up to 5 cm laying flat on matrix, covering about 70% of the surface of this 9x8x4 cm specimen @ 55.00. 

PETROLEUM variety BITUMEN- Cumberland Mine, Smith Co., Tennessee 
Although known from the Elmwood Mine, this is the first (?) reported specimen of natural petroleum/hydrocarbon  (variety bitumen) from the Cumberland Mine. It occurs as small, black, viscous balls to 6mm in an exposed seam of  sphalerite on limestone, with strontian-rich barite at the back of the piece. Professionally trimmed, the specimen  displays well and stands upright (see our image on Mindat.org), with one side view exposing tiny, gemmy, pale  brown sphalerite crystals as well. Only one available, size about 8x6cm @ 150.00. Carefully preserved and  perhaps unique for the Cumberland.

PHILIPSBURGITE (TL)- Black Pine Mine, nr. Philipsburg, Montana 
Recently uncovered in our warehouse, a flat of excellent, emerald-green micro crystals of philipsburgite scattered  over quartz matrix, typically showing finely bladed micro crystals and rosettes! The crystals are typically overgrown  with minute quartz druses, making colorful, pale green vitreous balls, sometimes associated with pale green duftite,  malachite etc. Matrix sizes from 2cm to 6cm @ 15.00, 25.00, 45.00, 65.00 and 100.00 each for the most aesthetic.  Also available: One top specimen, a 7x5cm sample has a full coverage face of deep greenish blue philipsburgite  balls liberally coating quartz @ 450.00, certainly the best we have ever offered! Superb type-locality material, and  all with micro potential as well! 

REDMONDITE (IMA 2021-072)- Redmond Mine, Haywood Co., North Carolina 
This NEW SPECIES occurs as minute, generally colorless equant crystals in vugs within granular galena-sphalerite  ore. Formula: [Pb8O2Zn(OH)6](S2O3)4, monoclinic, IMA 2021-072. There are at least 14 (!!) other potentially new  sulfate and thio-sulfate minerals observed in this assemblage. Author's material, all with arrows and modest micro  potential at higher magnifications, specimens from 1cm to 2.5cm, priced according to quality and/or associations @  125.00, 175.00, 200.00, and 350.00 each. 

RHODONITE- Chimbonila District, Niassa Prov., Mozambique 
Very colorful, deep pinkish-red glassy cleavages and masses of rhodonite comprising matrix! From an unusual  locality rarely offered, these are likely from the Meponda occurrence, which is just across Lake Malawi from the  Malawi border. Attractive and quite pretty, relatively pure specimens from 2cm to 5cm across @ just 10.00, 20.00  and 35.00 each. 

RHODONITE (Slickenside)- Franklin Furnace, Sussex Co. New Jersey 
A old specimen, collected by famous geologist E.W. Heinrich and accompanied by his original label. A specialist in  uraniuim minerals, Heinrich collected worldwide and was likely not completely familiar with Franklin species. His  label suggests that the large, slickensided pink mass of an exposed surface area of 8x6cm could either be  sussexite or rhodonite, here the latter being correct. The ore sample is otherwise granular franklinite and willemite  (quite fluorescent), and the slickensided rhodonite is rather waxy in appearance with spotty calcite overlays and  moderately colorful. Overall specimen size is about 9x7x5 cm @ 65.00. 

SCORZALITE with TOURMALINE- Chandlers Mill, Newport, Sullivan Co., New Hampshire  An interesting specimen from an old locality, also with much confusion regarding its naming. Scorzalite occurs here  as dark blue masses, once thought to be lazulute, lightly scattered in a white pegmatite matrix, showing small  crystals of black tourmaline (assumed to be schorl). The original specimen came from Willard L. Roberts, famous  mineralogist and Professor from the South Dakota School of Mines and for whom the minerals robertsite and  pararobertsite were named. The Roberts label accompanies the piece, and it, too, mis-identifies the scorzalite as  lazulite, and unfortunately uses the "Smith Mine, Chandlers Mills" as the locality. A long and detailed treatise on  Mindat confirms that "Smith Mine: is an incorrect reference (to the landowners' name), as two other Smith mining  operations were active in the area. Overall 8x6cm @ 55.00. 

SELENIUM- Kladno (Schoeller) Mine, Bohemia, Czech Republic 
Old material, here as nearly black powdery aggregates on matrix, collected many years ago when the locality was  known as the Schoeller Mine. Small samples from about 2cm to 4cm across @ 40.00, 60.00 and 85.00 each,  acquired years ago during one of our eastern European trips, and only a few on hand. 

SULVANITE with VOLBORTHITE- Thorpe Hills, Tooele Co., Utah 
This small specimen was collected at a prospect in the western side of Thorpe Hills sometime prior to 1985, likely  from the same area that was identified as only the second U.S. occurrence of sulvanite, a Cu-V-sulfide, in a 1973  American Mineralogist article. The mineral occurs as minute metallic masses lightly scattered in a calcite/dark  carbonaceous limestone marix, locally altering to greenish volborthite when carefully viewed under the 'scope. An  unusual occurrence, now noted as the "South Thorpe Hills copper prospect". The TN )ex-M. Jensen) measures  2.5cm across @ 95.00. One only! 

TRASKITE- Esquire #1 Mine, Rush Creek, California 
Minute reddish brown grains of traskite, sparsely scattered in sanbornite and quartz matrix, occasionally with other  species such as macdonaldite, titantaramellite and others. Old Cureton stock, type locality material, specimens  from about 2.5cm to nearly 6cm across @ 20.00, 35.00, 50.00 and 75.00 each.

TUSCANITE- Sacrofano Caldera, Rome Province, Italy 
Colorless to greyish white micro intergrown lath-like aggregates and isolated rod-like crystals of tuscanite sparsely  scattered in matrix. An interesting species and samples that will yield good micros, rarely offered any longer from  this classic locality. Old stuff, specimens from 2.5cm to 5cm across @ just 15.00, 30.00 and 45.00 each. 

VARISCITE- De Linde Mine, Avant, Arkansas 
Bright, bubbly green balls of variscite richly scattered in seams and on matrix, many with flattened sprays of minor  wavellite. Old, choice material from the early 70's, most with good micro potential, matrix sizes from about 2.5 to  8cm @ 5.00, 8.50, 15.00, 25.00 and 40.00 each. Attractive and colorful stuff! 

WHITEITE-(MnMnMn)- Foote Mine, Kings Mt., Cleveland Co. North Carolina 
Excellent, colorless to pale brown, tiny rod-like crystals in sugary aggregates perched in vugs in pegmatitic matrix.  Recently approved (IMA 2021-049), the mineral is the rarest of the whiteite supergroup. Only a few specimens on  hand from the type locality, all author's material with modest micro potential and occasionally with whiteite- (CaMnMn) and/or mangangordonite, matrix sizes raange from about 1.2cm to 2.5cm @ 150.00, 200.00 and 300.00  each, depending on quality. 

ZIRCON (FL)- Brevig, Telemark, Norway 
An old specimen from the Michigan College of Mines (1897-1926), showing numerous small, brownish tetragonal  crystals frozen in matrix. The mineral displays bright yellowish fluoresence under SW UV, and the locality is  somewhat obscure today, formed in 1838 and later merged with Porsgrunn in 1964. A representative example of  the mineral from this old locality with decent coverage and several unknown associations, size about 5cm @ 55.00  with MMC label.

Our 49th Year

ALMANDINE- Bella Vista claims, Mitkof Island, Alaska
Collected by the claim holder of this interesting locality in the Alexander Archipelago, these are nicely formed,
deep red almandine garnet crystals in dense schist matrix. The crystals (1 cm) are generally smaller than the
Wrangell Island samples, but with quite sharp dodecahedral faces and modifications. Matrix sizes range from
5cm to 6cm @ just 10.00 each. Excellent locality!

AMPHIBOLE variety ASBESTOS- Loudon County, Virginia
A very old "box of asbestos" of fibrous amphibole, ex-Michigan Mining School (1885) and accompanied by their
label, a succeeding one from the Michigan College of Mines (1897) and an early caligraphic label, likely 1870s
vintage of unknown origin. We dated 1870s as we have several other samples of identical handwriting, some
pinpointing 1876 as the acquisition date. The specimen was apparently donated by N.W.N. Noland, a Major in
the Confederate army and graduate of the University of Virginia law school who would later become the general
agent of the Virginia Bureau of Immigration. The material is soft, loose and fibrous, beige in color, and covers
the bottom half of an 11x7x3 cm box. We'll include a copy of Noland's obituary and all the old labels at just
60.00 for this historic lot, locality noted as "Virginia Marble Quarries, Loudon Co., Va.".

Very tiny samples mounted on adhesive stubs @ 150.00 each. List alternates!

CHALCEDONY var: CONDOR AGATE- Andes Mountains, Mendoza Province, Argentina
Perhaps the most beautiful of South American agates, "Condor Agate" shows excellent banding of reds,
browns, yellows and blues in very attractive fortifications and splashes. The actual beds are some 6000 feet
above sea level in a Cretaceous rhyolite, these specimens collected many years ago. We have a small lot of
superb, hand-polished polished nodule halves in which the uncut rough currently brings as much as $100 a pound (!!). Handsome specimens, typically 3.5cm to 6.5cm across @ 35.00, 50.00 and 75.00 each. Great old-
time stuff!

CORUNDUM in ANORTHITE- Barsooka River, Kyschtymsk, Ural, Russia
An old Michigan College of Mines specimen, sporting a rather ugly but large 3.5cm crude greyish-blue to nearly
black corundum crystal of imperfect, nearly equi-dimensional habit, surrounded by white anorhtite in a hard
biotitic matrix. An earlier label suggest mid-1870s acquisition based on others we have seen with identical
handwriting. The current name for the area is Kyshtym, site of a hidden nuclear disaster in 1957 within
Chelyabinsk Oblast that was not revealed until 1980. A large and quite ugly specimen from an obscure locality,
overall size about 10x7x6 cm with three old labels @ 100.00.

ELBAITE ("Watermelon")- Aricanga Mine, Sao Jose de Safira, Brazil
Recently acquired from the mine owner, a modest lot of watermelon tourmaline crystals without matrix, these
showing excellent green color with a core or thick band of pink as well. The crystals are singly terminated and
range from 2cm to 3cm tall, all with excellent color and less expensive than typically seen here in the U.S..
These attractive specimens weigh from about 28 cts to 57 cts. each, offered at 350.00, 400.00. 450.00 and one
at 685.00. List alternates!

FLUORAPOPHYLLITE-(Na)- Molibden Mine, Tyrnyauz, Caucasus, Russia
The most unusual of the fluorapophyllite group, this Na-dominant mineral was found at this new locality in the
late 1980s, but only recently confirmed as the Na member of the group. It occurs as small (2-3mm) colorless
single crystals without matrix, most showing good tetragonal dipyramidal habit. Only a few on hand from this
molybdenum mine in the Baksan Valley @ 95.00 each crystal.

FORSTERITE variety PERIDOT- Sapat, Kohisthan, NW Frontier, Pakistan
Good quality single crystals of apple-green peridot without matrix, all showing good prism faces and a sharp
single termination. Selected from a large lot of cutting material, these are quite fine as thumbnails or some as
cutting rough, sizes from 0.8cm to 2.7cm tall @ only 35.00, 45.00 and 55.00 each.

GAIDONNAYITE- Mont St. Hilaire, Quebec, Canada
Named for the famous Canadian mineralogist, the mineral occurs as rounded to almost blocky microcrystals and
aggregates, varying from translucent pale yellow to gray to nearly opaque, scattered in matrix. Occasionally
exhibits fluorescence as well. Old stuff, type locality of course, most with decent micro potential as well, 1cm to
6cm @ 15.00, 35.00, and 55.00 each.

GENPLESITE- Shaft #1, Oktyabr'sky Mine, Talnakh, Russia
This extremely rare mineral occurs as microscopic, platy colorless laths here at the type locality for the species,
better known for its sulfide assemblages. Formula: Ca3Sn(SO4)(OH)6*3H2O, hexagonal, the only natural tin
sulfate known. It is the Sn-analog of despujoisite and schaurteite, and the Ca-Sn analog of fleischerite. A very
tiny colorless lath in a 2cm vial @ 225.00, and you will need at least 15x to see it! Author's material; list
alternates.

GRIMALDIITE- Yuzhno-Saranovskoe Deposit, Perm Krai, Russia
This deposit near the Laki train station has produced a number of interesting minerals, perhaps best known for
the bright green uvarovite garnets found in the area in the past. Grimaldiite occurs here as tiny, bronze to nearly
black, lustrous lamellar aggregates on matrix, some with micro uvarovite as well. A rare mineral, matrix sizes
from 1.5cm to 2cm @ 145.00, some with modest micro potential under the 'scope as well.

GRUNERITE- Villa Real, Tras os Montes, Portugal
A typical in appearance but less common member of the amphibole group, grunerite occurs as dark green
prismatic crystal aggregates constituting most of these specimens. Each is provided with a copy of our in-house
EDS spectra from 1998 confirming the Fe-Si-O composition of the mineral. Sizes from 2.5cm to 5cm @ 15.00,
30.00 and 45.00 each. Excellent locality material!

HEMATITE-(Scalenohedron!)- Arzanah Island, nr. Abu-Dhabi, Untd Arab Emirate
Very weird habit for hematite, here as small euhedral scalenohedral crystals without matrix, similar in form to
Goldschmidt's illustration No. 33 and modified No. 118. Collected in the early 1980s from this obscure and
unusual locality by a oil worker near the Straits of Hormuz, XRD-confirmed and with no evidence of
pseudomorphing. Very interesting morphology, good micro single crystals from 5mm to 1cm @ 15.00, 20.00 and
25.00 each, with the smaller ones unmounted, the better ones nicely mounted in an MM box. Rare habit and
locality specimens!

LUN'OKITE- Voron'i Tundra, Kola Pen., Murmansk, Russia
Old Cureton materila from the type locality for the species, this rare phosphate occurs as minute, colorless to
white platy aggregates, occasionally with associated mitridatite and/or albite and other phases. Only a few
available as single crystal grains in a vial @ 45.00, or as tiny matrix samples @ 65.00.

METEORITE- Sikhote Alin, Maritime Territory, Russia
From the classic and fabled meteorite fall of February 12, 1947, we have a number of professionally prepared
small meteorites from this gigantic occurrence! A type II AB iron (coarse octahedrite), this is one of the most
famous extraterrestrial artifacts, offered here as black, convoluted metallic masses, ranging in size from 1.5cm
to 2.5cm across @ just 10.00, 15.00 and 20.00 each. These make interesting but inexpensive surprise gifts,
too, so get a bunch!

MOLYBDENITE (Rhenian)- Childs-Adwinkle Mine, Pinal Co., Arizona
From material collected about 35 years ago, we have a modest lot of molybdenite specimens, here as small,
grey metallic plates perched on smaller quartz crystals and rock matrix from this old Copper Creek locality that
was mined in the 1930s. The material was once considered among the highest rhenium-containing
molybdenites (up to 580 ppm) ever found, making for the interesting variety "Rhenian Molybdenite". A few have
sparse, non-descript pale coatings of secondary copper minerals as well. Specimens are generally lean but
sizes range from about 2.5cm to 10cm across @ just 7.50, 15.00, 25.00, 40.00 and 60.00 each.

MOTTRAMITE pseudo @ WULFENITE- Total Wreck Mine, Pima Co., Arizona
Greyish black brittle masses of somewhat iridescent, brilliant micro mottramite crystals richly scattered and
covering matrix, a few occasionally as incrustation pseudomorphous after 1cm or larger wulfenite plates. From
the original find in the 1960's, we have a few specimens without the pseudos but often with colorless calcite
crystals from 2.5cm to 10cm @ 10.00, 25.00, 45.00 and 75.00 each; the incrustation pseudomprphs range from
3cm to nearly 6cm samples @ 40.00, 55.00, and 80.00 each. Decent micro potential on all!

MUSCOVITE (ROSE)- Harding Mine, Taos Co., New Mexico
From the famous locality that produced so many delightful, pink platy muscovite specimens incorrectly labelled
as lepidolite, we have a large selection of samples showing this colorful mica well scattered in white platy albite
(variety clevelandite) matrix, occasionally with minor spodumene or other phases. Much of this was collected by
Ted Morley in the 1950's and 60's, and sizes range from about 2cm up to 10cm, mine-run material reasonably
priced at just 5.00, 10.00, 17.50 and 25.00 each.

OPAL (Gemmy!)- South Wollo Zone, Amhara Region, Ethiopia
Gem quality opal has been coming out of Ethiopia for several years, and you can find tiny bits at mineral shows
for about $8/gram. Often called "Welo" opal, these show some good transparency with associated rich firey
areas as well, rather attractive and competitively priced for larger samples @ roughly $10 per gram (not the
$25/g you will see from cutting rough suppliers for this size!) Specimens ranges from about 2.5cm to 4cm
across (!!), weights from about 9 grams to more than 45 grams, @ 95.00, 150.00, 250.00 and 450.00 each, with
some variation in between. Don't get a tiny bit, get a specimen you can see!

PATYNITE- Patyn Mt., Tashtagol, Kemerovo, Russia
This relatively new species was found about a dozen years ago but only recently IMA-approved (2019-018). It
occurs here as rich, colorless to greyish elongated coarse crystals in this southern Siberian type locality.
Formula: NaKCa4(Si9O23), triclinic, and a new structural type. Rich specimens about 1.5-2cm @ 135.00 each.

PETERSITE-(Y) (TL)- Laurel Hill, Secaucus, Hudson Co., New Jersey
From the discoverer's find in 1981, we have mounted specimens (by Nick Facciolla) from the original material
subsequently described the following year by Peacor and Dunn! These occur as extremely small, yellowish
green micro crystals in tiny groups and small isolated clusters, typically scattered over botryoidal malachite
and/or corroded chalcopyrite. All are in micro boxes and priced according to the number of clusters and quality
of same, matrix typically 4mm to 7mm @ 45.00, 75.00, 100.00 and 125.00 each. Perhaps the last available
world supply of the species from the type locality, but you will need some serious magnification on these!

RAMDOHRITE- Chocaya-Animas Mine, Potosi, Bolivia
Extremely tiny, longitudinally striated prismatic crystals of this rare mineral embedded in pyrite/stannite masses,
occasionally with tetrahedrite-freibergite group series phases as well, ex-Alfredo Petrov. Small masses
scattered in a vial @ 45.00 each - fun to hunt for micros!

SCHORL- Bierman Pegmatite, Bethel, Connecticut
An old specimen, ex-Cilen Collection via the Franklin Mineral Museum, here as elongated black tourmaline
(schorl) crystals to 6cm long frozen in micaceous rock matrix. One edge has a small, reattached crystal, but the
largest ones are intact and form much of the specimen. Both labels included, overall size about 8x6cm @
75.00. A wonderful locality piece but one only available!

SELENIUM- 400 level, Vulcan Mine, Gunnison Co. Colorado
Relatively pure, greyish black powdery masses of selenium originally harvested from the 400 level of the mine in
1925! Known more for tellurides, the material is ex-David New and may be from assay concentrates rather than
in-situ collected sample, a generous supply in 2cm glass vial @ 45.00 each.

SILVER- Rochester Mine, Pershing Co., Nevada
Minute flattened platelets and streamers of bright native silver sparsely scattered in white, cherty kaolinite-like
matrix, or as micro, nearly black wirey masses on iron-stained drusy quartz. From an obscure locality, we have
a few modest specimens from 1.5cm to 2.5cm @ 10.00, 15.00 and 20.00 each. Ugly stuff, some with decent
micro potential and from an uncommon locality, collected about 25 years ago!

SMITHSONITE w/ "CALAMINE"- Masua, Inglesias, Sardinia, Italy
A weird old specimen from one of the classic European localities! A strange, convoluted mass with numerous
exposed seams and voids offering brownish, botryoidal smithsonite, along with small crystalline groups of
hemimorphite crystals. Ex-A.E. Seaman Museum, and accompanied by their old cardboard display label, easily
considered a classic "dry bone" ore specimen that measures a hefty 11x7x6cm @ 85.00. One only!

TOPAZ- nr. Dassu, Shigar, Gilgit-Baltistan, Pakistan
A superb single crystal without matrix, show a perfect pinacoid termination and gem quality transparency, all
with an fine, champagne colored hue throughout. Prism faces are also excellent, as are all the well-developed
vicinal faces completely surrounding the crystal. Acquired in 2005 for $1K, this gem-quality crystal stands 2.5cm
tall and 1.7cm wide, offered at just 1250.00. One only!

UKLONSKOVITE- Cetine Mine, Siena, Italy
From one of the few known localities for the species, this secondary sulfate mineral occurs as colorless to white
prismatic minute crystals on matrix. Uklonskovite may be associated with other rare sulfates and tufts of white
gypsum crystals. Obtained from the late Dr. Giancarlo Brizzi (brizziite) some years ago, we have a few
capsules at 20.00 each, or matrix specimens from 1cm to 4cm @ 25.00, 35.00, and 50.00.

VEENITE- Taylor Pit, Madoc, Ontario, Canada
Micro silvery grey crystalline aggregates of this rare species sparsely scattered in/on marble matrix. Collected
in 1966 by Steacy and Moyd (steacyite, moydite), we offer pure crystallized specimens from 1mm to 4mm
individually x-rayed and probed in 1cm probe mounts @ 40.00 and 60.00 each, or as matrix specimens from
1cm to 5cm @ 45.00, 65.00, 85.00 and 125.00 each. Rare, and from the type locality!

WHITLOCKITE- Tip Top Mine, Custer Co., South Dakota
Minute vitreous micro crystals of whitlockite scattered over quartz matrix, some with minor carbonate-
hydroxylapatite as well. From one of the classic localities for the species, old material from Bill Roberts' time at the School of Mines, coverage will range from lean to very rich, all reflected in the price. Overall matrix sizes run
from about 2cm to 5cm across @ 25.00, 45.00, and 75.00 each, depending on coverage.

WULFENITE- Fourth of July Tunnel, Eureka Co., Nevada
From the many sub-localities noted at Prospect Ridge, we happily add an uncommon listing for wulfenite, here as tiny, very thin, water-clear to gossan-encrusted tabular crystals well-scattered on limonitic matrix, largely un-
reported from the area. Excellent micro potential on these, and matrix sizes range from about 2cm to 5cm across @ 10.00, 20.00 and 30.00 each, with a few larger: please inquire. Not pretty without the 'scope!

YTTROTANTALITE-(Y)- Hoeydalen, Toerdal, Telemark, Norway
This rare mineral occurs here small, as dark brown, glassy aggregates and partial crystals, lightly scattered in
thin seams and pods in white albite matrix. Unusual stuff found in 2009, specimen sizes ranging from about 3cm
to 4cm @ 45.00 and 60.00 each.

YUGAWARALITE- Wolf Point, Colwitz Co. Washington
Collected in 2002 by the late Rudy Tschernich (tschernichite) from the Mount Saint Helens tree farm at the
200/237 Road quarry, these are TN sized specimens showing good micro crystals of colorless, somewhat
tabular and elongated crystals of this uncommon zeolite perched in vugs in brownish basalt matrix. Excellent
micromount potential, these select specimens average about 2cm across @ just 20.00 each.

ZARATITE- Lord Brassy Mine, Tasmania, Australia
Bright green crystalline encrustations of zaratite on serpentinite matrix. Nice examples of this colorful nickel
carbonate from a classic locality, in sizes from 2cm to 6cm at 10.00, 15.00, 25.00, and 40.00, acquired many
years ago during Forrest Cureton’s excursion to Australia and Borneo.

COLLECTIONS
ASSORTED MINERALS – Various Localities
These lots are from an exceptionally large collection of mainly eastern U.S. minerals with occasionally other
localities that had resided in a N.Y. university holding for some time. We need room to for new arrivals and are
blowing out the collection in lots of twenty (20) specimens for just 125.00 per lot plus shipping. Prolific localities
are represented, with no exact duplication in each collection, and no specimen smaller than about 4cm, some
up to 6cm or more overall. Expect mostly common minerals, often ugly, but many collected in the 1940s, 1950s
and later, all individually labeled. Each lot of 20 is just 125.00 plus shipping, and we will try to provide NO
duplication among multiple lots purchased at the same time! A fast and economical way to build a reference
collection!
FOSSIL COLLECTION- Pierre Shale, Pennington Co., South Dakota
We stumbled across a box load of these interesting fossils, but confess to being deficient in paleo knowledge
beyond some very basic identifications. These are from the Upper Cretaceous, probably ~65 million years old,
and they represent a range of ammonites, bacculites, scaphites and possibly others, all presenting as pearly
white to nearly black, lustrous and often slightly iridescent specimens in and out of matrix. The locality is near
Box Elder Creek, better known to mineral collectors for its excellent brown barites, and we wish to move these
quickly. Hence, the following offer: four fossil specimens in generous sizes averaging 4cm to 8cm across @ just
50.00 per lot, with precise ID work up to you. Note: Our shipping minimum on these lots will run 16.00 or more
due to size/weight of the specimens!

EPHEMERA
Mining Stocks- Syndicate Mines Company - Oklahoma
We have a couple of cancelled stock certificates from this Tri-State company, all issued in 1906-1907, elaborate
gold-hued border with excellent vignette of miners working underground with mine candles. Expect some
tattered edges, but these are interesting and can be matted and framed. Limit one per customer, please, at
15.00 each. A few unissued as well, same vignette and price. Please specify if you have a preference.
GEMS & ART
CHAROITE w/ TINAKSITE EGG- Chara/Tokko Rivers, Murunskii Massif Russia
A unique display item, a wonderful, deep lilac charoite egg nearly 6cm tall, showing excellent, silky chatoyancy,
with a few small areas of honey-colored tinaksite inclusions, as well as minor quartz and black aegirine. Only
one available, about 135 grams, at just 200.00, with antique brass stand included.
OPAL MOSAIC CABOCHONS - Australia
Excellent, fire opal inlay in black base matrix, artistically presenting a superb butterfly mosaic. Calibrated at a
standard 18x13mm, these make interesting works of art using precious Australian opal, nicely presented in a
glass-topped Bates box. Only a few available @ 30.00 each. Pretty stuff!

LITERATURE/BOOKS
We will try to offer a modest selection of titles from our extensive book inventory with each mineral list. Virtually
all of those listed here are new copies. We present author, title, brief description, year of publication, type of
cover (soft-SC, hard-HC, spiral bound

CATALOG 22106 – Volume XLVIII, No. 6

ACANTHITE on FLUORITE- Moldava, Teplice District, Czech Republic
Old material collected many years ago by a Czech geologist, comprised primarily of massive fluorite with lesser
calcite and quartz, upon which small, grey-black aggregates of metallic acanthite are scattered, some with
decent micro potential as well. Some secondary copper arsenate minerals occasionally present as well,
specimens average 6 cm across @ just 45.00 each. Limit one per customer, please.

ALUM-(Na)- Vulcano, Lipari Isl., Sicily, Italy
Old Cureton stock comprised of tiny colorless to white, glassy aggregates sparsely scattered in a 3cm corked
glass vial. Ugly stuff but rarely offered at just 15.00 per vial.

AMBER- Jambi Province, Sumatra, Indonesia
An off-beat locality for this relatively young amber, typically just 20 to 30 million years old, here as dark brown to
orange-brown masses comprising matrix, many still showing elongated inclusions of replace, pale colored wood
texture. We have not found any insects yet, but the material is certainly interesting and brilliantly fluorescent
(blue-white, LW and SW UV) as well. Size range from 2.5cm to 6cm across @ just 10.00, 20.00, and 35.00
each. Neat stuff!

BARITE- Cartersville, Bartow Co.,Georgia
An old lot of greyish barite crystals in typical "spearpoints" on little matrix. A label in the flat indicated
"Centerville, Georgia", but by comparison to other specimens in our inventory, it was clear these were from the
Cartersville Mining District. Vintage is probably 1960s or 1970s, and the crystals are somewhat flat, opaque, but
in decent upstanding groups that make for good reference specimens. Most specimens have 1cm to 2.5 cm crude crystals, overall in the 4cm to 5 cm matrix size range at just 20.00 each, one exceptional, large group, ex-
Mecke Collection, about (x6cm with crystals to 5cm tall @ 95.00. One only of the latter!

BAYLDONITE- Loman Mine, Mineral Co., Nevada
Micro, medium green botryoids of vitreous bayldonite sparsely scattered on matrix, typically with dull, earthy
yellowish masses of a Pb-Sb-oxide that is likely oxyplumboromeite or a similar phase. An obscure locality near
the former Simon Mine in the Bell Mining District, specimens from about 2cm to 4cm @ 8.50, 12.50 and 20.00
each, some with micro potential as well.

CALCITE- Tonglushan Mine, Daye, Hubei, China
Featured in the September 2021 issue of Mineral News, we have an excellent selection of what we consider
among the finest calcite examples China has produced to date. Specimens show large (to 9cm) scalenohedral,
slightly lavender-hued crystals on matrix, some doubkly terminated, or wildly striated, deliciously transparent
equant contact twinned crystals to 7cm, excluding matrix! All are undamaged and very aesthetic, high-end
specimens, sizes from 6cm to 10cm across, not cheap, at 600.00 to 2500.00 each! Check out the article for
images, and specific inquiries invited.

CHALCEDONY pseudo @ ARAGONITE- Rancho Coyamito, Sierra del Gallego Mexico
Among the most famous of Chihuahua agates, the Coyamitos rarely show elongated "bars" of aragonite that
have been replaced by the chalcedony, displaying "fingers" that reach into the agate core. Depending on how
the agates are cut, they can appear as occasional "eyes" as well. We have several very colorful, expertly
polished, end-cut nodular specimens showing the pseudomorphs, sizes from about 7cm wide to 11cm wide @
just 75.00, 100.00 and 125.00 each, others selling these for $150 to $2500! If you prefer smaller, finely banded Coyamitos without the pseudos, we have many polished nodular halves, most with deep red, brown, grey and/or white concentric banding and occasional quartz centers, very attractive and very reasonable for this quality of complete halves, sizes from about 2.5cm to 4.5cm across @ just 15.00, 25.00 and 40.00 each, very far below the $100 to $500 prices elsewhere! Wonderful old stuff, and we can even supply an assortment of five polished halves for just 100.00!

CHALCEDONY pseudo @ RHIZOLITHS- Central Java, Indonesia
Weird stuff, here as stalactitic fingers of chalcedony, all with hollow centers often purported to be pseudomorphs
after fossil bamboo wood. Colors tend to be pale cream to light brownish, and these are lightly tumbled polished,
most showing interesting external ridges and forms with varying sizes of the columnar central voids. We've seen
them offered simply as "stalactites", as well as pseudos after fossil bamboo, but they are likely after earlier
cores of iron oxide rhizoliths. These range from about 2.5cm to 6cm in length with varying thickness and weight,
specimens priced at 30.00, 40.00, 50.00 and 75.00 each.

CLINOBISVANITE- Linka Mine, Lander Co., Nevada
This uncommon bismuth vanadate occurs here a brightly colored yellowish orange masses scattered on rock
matrix, occasionally with other secondary bismuth minerals. Both chemically and structurally confirmed, we have
a modest supply of specimens from about 2cm up to nearly 4.5cm across @ 15.00, 25.00, 45.00 and 65.00
each, depending on richness.

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 are on hand, the best one illustrated in the October, 2021 issue of Mineral
News, a gemmy 1.43 cts, 8x6x3mm @ 745.00. Also one smaller: 0.81 cts 7x6x2mm @ 480.00

DOMEYKITE variety MOHAWKITE- Mohawk Mine, Keeweenaw Co., Michigan
Mohawkite is a complex mixture of copper arsenides that are primarily domeykite, algodonite, rarely paxite and
As-rich copper that form rich metallic masses in exceptionally dense matrix specimens, occasionally with
potential rammerlsbergite and other phases. Rarities such as jeankempite and others have not (yet) been
confirmed in the few specimens we have studied, but "hope springs eternal." Small but heavy specimens first
acquired prior to 1959, ranging from about 2cm to 5cm across @ just 10.00, 20.00 and 35.00 each from this
classic locality for which the mixture assemblage was named.

DUMORTIERITE in QUARTZ xls- Vaca Morta Quarry, Boquira, Bahia, Brazil
Excellent, bright blue needles and sparys of dumortierite included in transparent, terminated quartz crystals.
Specimens range from 1cm mounted micros to 2.5cm thumbnails, all with fine color and crystal form. An
interesting and uncommon inclusion, these first hitting the market in 2015 and now disappearing. Mounted 1cm
micros @ 30.00 and 35.00 each, thumbnails @ 35.00 and 45.00 each, all depending on aesthetics. Pretty stuff,
and one source claims these are blue dravite crystals, but we are sticking with dumoretierite!

FLUORLUANSHIWEIITE IMA 2019-053- Shuk-Byul Peg. Sangilen Uppland,Tuva Russi
This NEW SPECIES presnts as rich, pale pink to lavender micaceous platy lamellar aggregates on greyish
quartz matrix. Formula: KLiAl1.5(Si3.5Al0.5)O10F2 - monoclinic, a new member of the mica group, IMA #2019-
053, the fluorine analogue of luanshiweiite. Second world occurrence, rich specimens average 2.5cm across @
95.00 each.

FORMANITE-(Y)- Cooglegone, Western Australia, Australia
This rather non-descript mineral occurs here as dull brownish masses richly scattered in and comprising matrix.
Very old material from the original find at the type locality, specimens average about 2-3mm @ 25.00 each. Rare!

GEARKSUTITE- Skunk Mine, Jamestown D, Boulder Co. Colorado
A obscure locality not present in Mindat, gearksutite occurs here as dull, greyish-white masses lightly scattered
in an argillaceous granodiorite matrix. We acquired these sometime prior to 1980, and just stumbled across
them here in the warehouse. Distressingly unappealing but interesting nonetheless for the locality, sizes from
1cm to 5cm @ just 7.50, 15.00 and 30.00 each. If someone has a very old edition of Minerals of Colorado,
perhaps it can be found therein, but the modern hardcover notes several mines in the Jamestown District, but
not this one!!

GEDRITE- Skisshyttan, Dalarna, Sweden
From a well known locality for the species, gedrite occurs here as black, radiaiting aggregates well-scattered in
matrix. The material is known for the metavulcanite rock matrix, reported to be 1.7 billion years old! Specimens
range in size from 2cm to 6cm across at just 10.00, 20.00, 35.00 and 50.00 each, all with relatively good
coverage.

GISMONDINE-Ca- Osa Quarry, Roma, Italy
White to colorless gismondine-Ca crystals (1-3mm), some occurring with tiny spheres of phillipsite in small but
attractive specimens. These have had some great micro potential due to the potential presence of ludwigite and
aschcroftine found in some examples after trimming (but not found in these, unfortunately)! Specimens from
2cm to 4cm @ 20.00, 30.00 and 45.00.

HELVITE- Discovery Gulch, Sierra Co., New Mexico
Dark brownish, glassy crystalline aggregates and masses of richly scattered helvite in matrix from this well
known Iron Mountain No. 2 District. Once cited as "far more abundant here than in any other locality so far
reported in America" when discovered in 1941; we have a few old specimens likely collected from the 1942
USGS excavations, ranging in size from about 2cm to nearly 6cm across @ 15.00, 25.00, 45.00, and 60.00,
priced according to richness.

KAERSUTITE- near Hoover Dam, Mojave Co., Arizona
One of the few titanium bearing amphibole minerals, kaersutite occurs as greenish black glassy crystals frozen
in camptonite rock matrix, with occasional prism faces evident. First described from the area around 1950,
these are reasonably priced specimens with moderate coverage, 3cm to nearly 6cm @ 15.00, 20.00, 30.00 and
45.00 each.

KELLYITE w/ ALLEGHANYITE- Bald Knob, nr. Sparta, Alleghany Co North Carolin
Moderately rare, tiny yellow-brown micro platelets of kellyite, variously admixed with pinkish alleghanyite,
sonolite, and galaxite as typical assocaitions. Author's material and type locality for both kellyite and
alleghanyite, lean but quite good for the species, samples measuring 1.5cm to 3.5cm @ 20.00, 30.00, and 45.00
each.

LAURIONITE- Pacha Limani area, Lavrion, Attika, Greece
Excellent millimeter or smaller sized crysals of laurionite, colorless and transparent, as individuals and groups in
vugs in the ancient slag this locality is famous for. Good micro material, and may be associated with phosgenite,
aragonite etc. In matrix sizes from 2.5cm to early 4cm @ 35.00, 55.00, and 75.00 each, depending on quality.

MAGNESIOFERRITE- Langban, Varmland, Sweden

STEPHANITE with POLYBASITE- Champion Mine, Deer Lodge Co., Montana
From an old locality, we offered these more than 20 years ago and promptly lost them in our old warehouse in
New York. Recently relocated, these had been analytically confirmed, although still quite ugly as thin metallic
grey intergrowths and disseminated masses of these two unusual silver-antimony sulfides in a quartz-rich
matrix, occasionally with pyrite and possibly other phases. Matrix sizes from about 2.5cm to 6cm across @
20.00, 35.00 and 50.00 each, priced according to richness, not necessarily overall size.

VUONNEMITE- Poudrette Q., Mont St. Hilaire, Que. Canada
This uncommon mineral occurs here as tiny, pale yellowish crystals and aggregates sparsely scttered in matrix,
occasionally with steenstrupine or possibly other species. Old material from the Van Velthuizen find of the 1980s
at this prolific locality, all specimens with arrows, overall sizes from about 2.5cm to 6cm @ 30.00, 55.00 and

GEMS

CAT'S EYE CABOCHONS- Manmade
The fiber optics industry has spawned many interesting artifacts, and these cat's eye (aka "fiber eye")
cabochons are an outgrowth of the technology. All are precision cut 25x18 mm ovals, and they were produced
in variety of attractive, translucent colors, each showing excellent chatoyancy in the form of a longitudinal line.
We have seen these for silly prices passed off as genuine stones, but we offer a set of six different colors for
just 25.00 a set! Kinda cool....

ELBAITE TOURMALINE- Minas Gerais, Brazil
A wonderful selection of deep green, fully transparent faceted tourmaline, these primarily in free-form elongated
baguette shapes, varying in size from about 8x2mm to 12x4mm, weighing from about 0.5 carats to 1.3 carats
each. We have assembled a few choice lots of 8 stones, averaging a little over 6 carats in total weight, at just
55.00 per lot - less than 10.00 per carat!

RUBELLITE TOURMALINE- Minas Gerais, Brazil

CATALOG 22105 – Volume XLVIII, No. 5

ARSENOPYRITE with QUARTZ etc.- Noche Buena, Zacatecas, Mexico
From material obtained in the late 1960s, largely comprised of silvery-grey wedge-shaped crystals of
arsenopyrite to 5mm or more, well scattered on matrix. The most common association is micro, elongated
quartz crystals, occasionally minor pyrite and/or other sulfides. Specimens from 3cm to 7cm across @ just
10.00, 20.00, 30.00 and 45.00 each. Neat old stuff, ex-Cureton.

ATACAMITE- Mina La Farola. Atacama, Chile
Old specimens obtained from Al McGuinnessite and others many years ago, presented here as attractive, dark
green rod-like micro crystals of this interesting copper mineral perched on matrix, occasionally associated with
other copper minerals. While we have the species from many other localities in Australia and elsewhere, few
compare to these in richness and coverage, many with good micro potential as well! Analytically confirmed
(copy supplied), and SEM studies have found microscopic dioptase, pseudomalachite and others. Specimens
range from about 2.5cm to 7cm @ 15.00, 30.00, and 45.00 each.

AVOGADRITE- Mt. Vesuvius (eruption of 1926), Italy
This extremely rare volcanic sublimate, a boron fluoride mineral, avogadrite occurs as powdery orange-yellow
opaque masses with minor matrix. Type locality, of course, from the 1926 eruption, offered as small grains @
55.00 each.

BOULANGERITE- Noche Buena, Zacatecas, Mexico
Slender, steely-grey needle-like crystals and hairs of boulangerite on matrix, occasionally with minor pyrite.
These are ex- A.E. Seaman Mineral Museum stock, early 1970's vintage often sold as jamesonite, but XRD
work by John White on material from this specific locality determined most of it is, indeed, boulangerite. RIch
specimens, sizes from about 2.5cm to 6cm across @ 15.00, 25.00 and 40.00 each; one rather flat, fully covered
12x8cm specimen @ 95.00. List alternates!

CAYSICHITE-(Y)- Ploskaya Mt., Keivy, Kola Peninsula Russia
This uncommon mineral occurs here as minute, snow white spherulitic pods in yellowish to violet grey yttrian
fluorite, often with albite and occasionally minor amazonite and quartz. An interesting assemblage from this
2004 discovery, specimens from about 1.8cm up to nearly 4cm across @ 25.00, 35.00 and 50.00 each.

CHALCOPYRITE etc.- International Nckel Co., Sudbury, Ontario, Canada
This heavy ore specmen was collected in 1977 by Dutch mineral dealer Henrik Rozenbroek during a trip to the
International Nickel Co. Mines (after 1976 known as INCO) in Sudbury. At the time, numerous mines were
worked by the comapny in and about Sudbury, one of the largest nickel fields in the world. This specimen
obviously contains several lesser sulfide minerals, measures a very stout 10 x 8 x 7 cm and weighs nearly 4 lbs,
classic ore sample from the district @ just 85.00. One only.

CINNABAR in OPAL- Glass Buttes, Lake Co., Oregon
Interesting samples of massive, cream to grey hued opal with orange-red inclusions of cinnbar scattered
throughout the opal. Colorful material, these samples were collected nearly 40 years ago in this remote area,
and specimens range from 2.5cm to nearly 7cm across at just 7.50, 15.00, 25.00 and 40.00 each.

COPPER on PREHNITE- Nipigon Bay, Lake Superior
An old Michigan College of Mines specimen, originally provided by A.E. Foote and with a tiny partial Foote label
attached. This is an obvious water-worn cobble with exposed seams and a large 4x3 cm vug of very pale green
botryoidal and crystallized prehnite upon which tiny native copper crystals and specks can be seen under
magnification, and likely datolite present as well. I immediately assumed this was a Michigan piece, only to see
that Nipingon Bay is on the northern shore of Lake Superior opposite the Upper Peninsula, and very close to
Isle Royale, actually situated within the Canadian portion of Lake. A great curiosity, the piece is likely prior to 1927 when the College changed names. A hefty specimen, size about 9x9x4 cm with two old MCM labels @
100.00. One only!

DURANGITE- Unnamed Prospect, Sierra Co., New Mexico
Orange micro crystals of durangite are liberally scattered throughout a matrix which also shows micro crystals of
reddish brown cassiterite, black hematite, and possibly other species. Good micro potential on the better pieces
from this Taylor Creek Tin Mining District locality, matrix sizes from 2cm to 5cm @ 20.00, 35.00 and 50.00 to
5cm or so, then 6cm - 8cm @ 75.00, 100.00 and 125.00 for the larger, richer specimens.

DYMKOVITE- Belorechenskoye, Northern Caucasus, Russia
This rare species occurs as minute (~0.5mm) yellow grains and crusty aggregates on dolomite, presented here
as tiny mounts on 1.25cm adhesive disks. A weird uranyl-arsenite, formula: Ni(UO2)2(As3+O3)2*7H2O,
monoclinic. Dymkovite is the Ni-dominant analog of seelite and is named in honor of Russian mineralogist Yuriy
Maksimovich Dymkov (b. 1926), specialist in uranium mineralogy. Exceedingly rare, type locality material, of
course, IMA #2010-087, only two available @ 145.00 each.

EPISTILBITE- Kosmos, Lewis Co., Washington
A moderately unusual zeolite, epistilbite occurs here as white, translucent mm-sized sharp blocky crystal
groupings in small vugs scattered in basalt, possibly associated with other zeolites. Old material, ex-Rudy
Tschnerich. Nice micro material, overall sizes are 1cm and 4.5cm @ 15.00 and 45.00 each.

ERDITE- Coyote Peak, Humboldt Co., California
Coyote Peak is a mineralogically unique occurrence of unusual sulfide minerals, erdite being a hydrated sodium
iron sulfide. Erdite is found as minute, sparse dark red-brown to coppery-red masses and aggregates scattered
through rock matrix, associated with pyrrhotite and other sulfides, and likely to include many of the other rarities
known from the locality! Named for the late Dick Erd, USGS mineralogist, we have only a few samples, portions
of the co-type specimens, in sizes from 2.5cm to 6cm @ 75.00, 125.00, 175.00 and 250.00.. The very last of this
material; list alternates!

ERIONITE- Ash Meadows Dep., Shoshone, Inyo Co. California
An older specimen, ex-A.E. Seaman Mineral Museum, presented as rather chalky, beige erionite (cation
undetermined) completely comprising matrix. The locality is rather obscure, extracted from the USGS Minerals
Resources system of 2005. The material appears identical to that of the Eastgate deposit across the border in
Churchill County, Nevada. Specimens from both localities on hand, average about 4cm across @ 30.00 each.

FLUORITE on QUARTZ (REPAIRED)- Dongshan Mine, Chenzhou, Hunan Prov. PR China
A tasty morsel of a high quality thumbnail, here as a completely transparent, very slightly green 1cm fluorite
cube grown into and on top of the tip of a nicely terminated, stubby 2.5cm quartz point. Although not evident, we
believe this specimen has been expertly repaired have labelled it as such. A very handsome combination of
early (1986) Chinese material, ex-Jensen Collection #3243, overall 3.5x2cm @ 200.00.

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

GRICEITE- Mont St. Hilaire, Quebec, Canada
This uncommon lithium fluoride occurs as minute, milky white micro crystals scattered in/on matrix, typically
associated with quartz, steenstrupine, eudialyte etc. rock matrix. Obtained in 1987 from one of the authors, we
have a number of good specimens on hand, sizes ranging from about 2cm up to large 9cm samples @ 45.00,
60.00, 95.00 and 150.00 each.

IRIDIUM var: RUTHENOSMIRIDIUM- Trinity River, Trinity Co., California
A small, flattened, silvery placer grain from the well-known PGM placer deposits of the Trinity River. The grain
has been analyzed and has a confirmed Ir-Os-Ru composition with lesser Fe present, typical for the locality.
Once its own species, ruthenosmiridium is now considered an Ru-rich variety of native iridium. Our EDS
analysis accompanies the 1.5 mm specimen @ 95.00.

KASOLITE- Penn Haven Jct, Jim Thorpe, Carbon Co., Pennsylvamia
Dull yellowish to orange-yellow filmy crusts of this uncommon uranium mineral sparsely scattered on dark graywacke sandstone conglomerate matrix. Collected in the early 1970s from the west shore of the Lehigh River, uranium deposits in the area have been known as early as 1874 and were eventually surveyed by the USGS for the Atomic Energy Commission in 1954 during the blossoming "nuclear age". While far from attractive, these are interesting locality pieces that are only mildly hot, with sizes ranging from 2.5cm to 4cm @
15.00, 25.00 and 40.00 each.

LONDONITE- nr. Mt. Bity, Antandrokomby, Madagascar
This rare mineral occurs as pale yellow, dodecahedral single crystals without matrix, the cesium-analog of
rhodizite. We have only a handful of analytically confirmed specimens, each accompanied by its own EDS
analysis with X-ray spectra, showing Cs>K dominance! After analyzing many, many samples, this is it! If you
purchased a "londonite" without an analysis, we'll bet you have a rhodizite instead, as these are visually
indistinguishable phases! Crystals range from about 3mm to 6mm across @ 95.00, 115.00 and 125.00 each
depending on size. Note: These are individually analyzed samples with corresponding EDS data for Cs:K
proportions!

MELANOPHLOGITE- Mt. Hamilton, Santa Clara Co., California
An enigmatic silica polymorph, melanophlogite is reported to be cubic SiO2 containing essential hydrocarbons.
We have a few samples of melanophlogite as very tiny, crude crystals, associated with opalescent botryoids and
crusts of chalcedony, often with miniscule overgrowths of melanophlogite on metamorphosed serpentine rock
matrix. Featured in Mineralogical Record (Vol. 33 #3), these are mostly water clear, extremely small cubic
crystals, also fluorescent (LW UV) yellow as well, specimens from 2.5cm to 4cm @ 20. 30.00 and 45.00 each.

NEPHELINE etc.- Egan Chute, Dungannon Twp., Ontario, Canada
Rather nondescript, greyish white nepheline masses largely comprising matrix, occasionally with minor "biotite".
Collected by E.W. Heinrich, some of the specimens show a small and dull, scattered orange fluorescence under
LW UV, likely from included sodalite or other phase. Specimens range from 2cm to 4.5cm @ just 5.00, 10.00
and 20.00 each; a few larger to 8+cm @ 45.00 each.

OSMIUM var: IRIDOSMINE- Trinity River, Trinity Co., California
Another analyzed placer nugget from this prolific PGM locality, here confirmed as an Os-Ir-Ru phase with Fe
detected as well, formerly known as the species iridosmine, the name now relegated to native osmium with
significant, but lesser, iridium present. The 1.5 mm specimen is accompanied by our EDS analytical work as
well @ 100.00.

PARASTERRYITE etc.- Pollone Mine, Lucca, Tuscany, Italy
This rare silver-lead-antimony sulfosalt occurs here at its type locality as minute, slender, metallic, orhtorhombic
needle-like crystals in white, dolomitic matrix. Under maginfication, the micro crystals are longitudinally striated,
whereas the more common sterryite (monoclinic and very similar structurally and chemically with a bit of copper
in its composition) found in these specimens is more typically flattened and without striations. Specimens
average about 4cm across @ just 75.00 each.

PECTOLITE variety LARIMAR- Los Checheses, Barahona Province, Dominican Republic
From a large lot of material collected in 1976 at the locality by well-known gem expert Joel Arem, we have
reference specimens of this strange material, here as pale blue masses and fibrous, radiaiting veinlets of
copper-rich pectolite lightly scattered in a rather ugly, greyish and punky limestone matrix. We've analyzed the
material (it is, indeed, pectolite), and even polished a few samples for ourselves (they improve dramatically with
cutting and polishing), but these are essentially weird geological reference pieces of this unique material known
only from this locality, either with a polished window or not, sizes from about 2cm to about 4.5cm @ just 15.00,
25.00 and 45.00 each.

SEAMANITE- Chicagon Mine, Iron Co., Michigan
Type locality material for this rather rare species, here as tiny, slender orthorhombic crystals without matrix. The
crystals tend to have a very pale rose to yellowish hue but are completely transparent and quite sharp, and
these will be a challenge for micromounters! Sizes average about 3 mm long @ only 25.00 each! Limit: 4/order.

SODALITE- Itaju do Colonia, Bahia, Brazil
From one of the uncommon nepheline syenites in this otherwise prolific mineral producing area, we have a few
deep blue, massive sodalite specimens comprising matrix, some with minor white spiderwebs of calcite and
potentially other species. Likely from the Hiassu farm, probably cutable due to its color and superior luster, but
not our thing. Specimens 2.5cm to 10cm across at just 5.00, 10.00, 20.00 and 35.00 each from this neat locality.

STILBITE-(Ca) etc.- Christmas Mine, nr. Hayden, Gila Co, Arizona
Small but excellent flattened sprays and radiating groups of salmon- colored stilbite well scattered on
hydrothermally altered diorite matrix, typically in exposed seams associated with an apophyllite group mineral
[likely hydroxylapophyllite-(K)], transparent calcite micros etc. None of the usual copper silicate phases are
present in this material, and the stilbite has been analytically confirmed in our lab, with EDS spectra provided
with each specimen, matrix sizes from about 4cm to 8cm @ just 20.00, 35.00 and 55.00 each. See our image in
Mindat.org, with reasonably good micro potential throughout!

SULFUR on GYPSUM- Djebel Chemsi, East of Gafsa, Tunisia
A great locality specimen comprised of massive patches of pale yellowish native sulfur scattered in and on white
gypsum matrix, perhaps with some pale tan anhydrite intergrowths as well. From an old collection, a single
specimen, quite flat, about 12x8cm @ 55.00. Only one unique sample from this otherwise barren region!

VESZELYITE etc.- Dongchuan District, Kunming, Yunnan, PR China
As featured in the August, 2021 issue of Mineral News, we have a small lot of hand-picked speicmens from this
2020 find. These are small, exceptionally attractive brilliant blue, crystallized specimens, typically in TN to 4cm
miniature sizes, all yielding superb micros and larger, vitreous, electric blue crystal sheaves to half a centimeter
or more on matrix, often with malachite, chrysocolla or other phases. A copy of analytical work accompanies
each sample! Specimens priced according to quality, not size, at 250.00, 400.00, 500.00, 650.00, 750.00,
1000.00 and 1500.00. Also on hand: two 9cm divergent quartz crystal groups, nicely terminated, with small
scattering of micro crystals @ 800.00, and a few matrix specimens with analyzed theisite in the 4cm range @
500.00. See the Mineral News article or our website for a few images!

VUORELAINENITE- Satra Mine, Finspang, Sweden
Submicroscopic greyish black inclusions of this rare species scattered in alabandite, sphalerite and pyrrhotite
ore matrix. Type locality material, the mineral was discovered on old specimens in 1980, as mining ceased here
in 1919. A wide range of unusual species in association can be expected, but all would require additional
analytical work. Matrix specimens from 2cm to 4cm @ 45.00 and 75.00 each.

VYSOTSKITE- Noril'sk, Krasnoyarsk Krai, Russia
Old Cureton stock of this uncommon palladium-nickel sulfide, recently uncovered here in the warehouse. The
mineral was named for Nikolai Konstantinovich Vysotskii (1864-1932) who discover the Noril'sk deposit. The
mineral occurs as submicroscopic, silvery white blebs in dark, Pt-ore from this famous deposit, originally
confirmed as (Pd,Ni)S by Cannon Microprobe in 1982, and offered here as small amounts of the rich, crushed
Pt-ore in a vial @ just 45.00 each. Please list alternates!

CATALOG 22104 – Volume XLVIII, No. 4

ALMANDINE- Stikine River, Wrangell Island, Alaska
Wrangell garnets seem to have been around forever, and this lot was purchased in 1958. Collected at the mouth
of the Stikine River, these show the typical euherdal garnet crystals perched in shistose matrix, most with
dodecahedral forms and occasionally modified by others. There are better garnets in the world, but these are a
collection classic widely distributed, with crystals ranging from 1cm to 2cm across, all embedded in matrix and
often less than perfect condition. Specimens range from about 4cm to 7cm across, priced inexpensively at just
10.00, 15.00 and 25.00 each, according to overall size and quality.

ARSENOPYRITE etc.- Ackerman Mine, Marmora Twp., Ontario Canada
A rather large and quite ugly ore specimen from this older gold mine in Hastings County, collected in 1982 by H.
Rozenbroek during his travels in Canada. Most samples from the locality have been etched to unveil good
arsenopyrite crystals, but this is unetched, rich fine-grained ore with intergrown pyrite and minor quartz and dolomite that shows at least one 5mm elongated arsenopyrite crystal embedded in the gangue silico-
carbonates, begging to be etched out. A heavy specimen in excess of 7 pounds (!!) and measuring 14x10x6 cm @ just 45.00. One only!

AUTUNITE- nr Honggiao, Pingjiang Co., Hunan, PR China
Exceptionally attractive radiating fans of brilliant yellowish green autunite without matrix, certainly the finest ever
found in China and equal to very best of old Daybreak Mine material from years ago. Pictured in the July, 2021
issue of Mineral News, these are likely from the mines of the Nanjingqiao Uranium Deposit, although our source
only specified "from mines near the village of Hongqiao" in Pingjiang County. Extremely hot, brilliantly
fluorescent, matrix-free specimens, very attractive, average about 5cm across @ 400.00 each. One large matrix
specimen with about 75% coverage of platy crystals to 1 cm rather than radiaiting fans (I prefer the latter), size
about 10x6cm @ 750.00. List alternates!

AXINITE-(Mn)- Dalnegorsk, Primorsky Krai, Russia
A superb crystal group comprised of several, highly lustrous dark brown terminated crystals of axinite-(Mn)
intergrown into an attractive group! Acquired in 1996 from the September Mine during the early days of
Dalnegorsk's marketing of outstanding minerals, this is ex-Jensen Collection #4939 and an extremely fine,
glassy specimen about 3.5cm tall @ 325.00. Most excellent!

BRANDTITE- Sterling Mine, Ogdensburg, New Jersey
Minute transparent to translucent micro crystals or lath-like aggregates of brandtite very sparsely scattered on
typical black willemite ore matrix, occasionally with minor magnetite. Priced according to overall quality, matrix
sizes from 3cm to 8cm across @ 25.00, 40.00, 60.00, and 75.00 each, a few larger, inquire.

CHALCOCITE, BORNITE, PYRITE- Butte, Silver Bow Co., Montana
An old E.W. Heinrich (heinrichite) specimen, accompanied by his somewhat tattered Univerity of Michigan label,
here as a massive ore specimen. The chalcocite is massive, with bl;ue iridescent bornite throughout, and pyrite
forms a 5cm long vein about 5mm wide running through one part of this hefty specimen. Overall size about
10x6x5 cm weighing a couple of pounds, at 55.00. One only!

DUSSERTITE- Tecoma, Elko Co., Nevada
Dussertite occurs as greenish earthy coatings in these relatively rich specimens. One of the more unusual
members of the crandallite group of minerals, dussertite being the barium arsenate analogue. These rather
unattractive specimens are in sizes from 1cm to 6cm @ 15.00, 25.00, 35.00, 50.00, and 75.00 each, depending
on size and coverage.

EDINGTONITE- Ice River, British Columbia, Canada
Stout opaque white crystals of edingtonite are richly scattered over calcite and rock, some with nice calcite
crystals as well. One of the less common zeolites, these edingtonite specimens have sharp, well formed crystals up to several mm's long, many with good micro potential as well. Overall sizes average 2cm to 4cm @ 15.00, 25.00, and 40.00 each.

EPISTILBITE- Su Marralzu Q., Osilo, Sardinia, Italy
Old Cureton material acquired many years ago, here as small white to slightly pinkish radiating crystal groups in
vugs in tough, basaltic matrix. Interesting reference material, many with decent micro potential as well, matrix
sizes from about 2cm to 5cm across @ 12.50, 20.00, 35.00 and 45.00 each, depending on quality, not size.

ERSHOVITE- Tsentral'nyi Mi, Rasvumchorr, Kola, Russia
A rare mineral at this Khibiny massif locality, here quite different than the type material in that it is yellow-orange
in color and comprised of easily discernable masses comprised of distorted, radial fibrous spherules in pods
averaging 0.5cm across, typically perched in voids among potassic feldspar, aegirine, sodalite etc. Only a few
specimens from this occurrence on hand, sizes range from about 3cm to 5cm @ only 75.00, 100.00 and 125.00
each, about half the price of the material from 25 years ago!

FERROSAPONITE- Levoberezhye Deposit, Evenkiya, Russia
This relatively new species from the Tunguska River area in Siberia occurs as tiny greenish brown balls
(0.2mm) included in Iceland spar calcite, easily visible with modest magnification. Formula:
Ca0.3(Fe2+,Mg,Fe3+)3(Si,Al)4O10(OH)2*4H2O. Wispy mordendite or tiny pyrites are occasionally present as
inclusions as well. Author's material, type-locality specimen sizes from about 1.3cm to 2.5cm @ 75.00, 100.00
and 125.00 each.

FLUORAPATITE- South Burgess, Leeds, Ontario, Canada
An old A.E. Foote specimen, comprised of dense, dark greyish blue massive fluorapatite without discernable
matrix. The Foote label is attached to the base of the specimen, and it is also accompanied by a Michigan
College of Mines label (circa 1897-1926) as well as an A.E. Seaman Museum label. The specimen measures a
hefty 9x7x5 cm @ 65.00. One only, rich enough to slab and cab if you dared..!

GOETHITE- Signal (Hill) Point, Staten Island, New York
An old specimen, ex-F. Mecke Collection, and surprisingly attractive for the species. The specimen is a
relatively large,slab-like habit of elongated stalactitic brown and black "cave-like" formations completely covering
one surface. An excellent but rather obscure New York City locality near the well known "Grymes Hill" location
known for its quartz and goethite specimens, and this sample aka "Signal Hill", too. One large and attractive old
specimen about 16 x 12 cm @ 125.00. List alternates!

HELLANDITE-(Y)- Evans-Lou Mine, nr. Wakefield, Que, Canada
Massive, dull tanish yellow to occasionally greenish hellandite-(Y) scattered in/on matrix. From the type locality
for the species, these rather non-descript specimens range from about 1cm up to 4cm across @ 15.00, 30.00
and 50.00 each.

KALIBORITE- Deposit #99, Inder Boron Deposit, Kazakhstan
A rarely offered species from this now abandoned underground prospect mine, offered here in two different
habits: small, greyish crystals of 1.3cm or more with little or no matrix, up to 2.5cm, all showing several sharp
faces but quite opaque @ 40.00 and 65.00 each; or as nearly clear, nicely transparent larger crystal fragments
but with less distinctive morphology that average 2.5cm across @ 50.00 each.

KALSILITE- San Venanzo Q., Terni, Umbria, Italy
From an older find, kalsilite occurs here as micro white prismatic crystals in vuggy matrix, typically associated
with bronze phologopite, melilite and occasionally fluorapatite and other species as well. Good micro potential,
specimen sizes range from about 3cm to 6cm across @ just 25.00, 35.00 and 55.00 each.

LAZULITE- 6mi NW of Jacksonville, Jackson Co. Oregon
Old material collected in the 1950s at the headwaters of Galls Creek and Jackson Creek, about 6 miles NW of
Jacksonville, our location is significantly more precise than previously listed elsewhere! The specimens show
rich pods of deep blue lazulite masses well scattered in granular quartz matrix, along with bladed muscovite and
trace sulfides. Specimens range in size from flattened 3.5cm specimens to hefty 7cm chunky samples @ just
10.00, 20.00 and 35.00, with a couple of the largest & richest @ 45.00 each.

MAGHEMITE- Gara Djebilet, Algeria
Old material that is dull greyish black to brownish and fine-grained, offered as small matrix samples. An
uncommon locality for eh species, specimens from 2.5cm to nearly 4cm across @ 20.00, 30.00 and 45.00 each,
or as small (4-5mm polished samples in probe mounts @ 65.00 each.

METAURANOCIRCITE- Annie Creek, Lawrence Co., South Dakota
Old Cureton stock originally acquired from Bill Roberts at the SD School of Mines decades ago, here as
yellowish green aggregates and crude platy crystals, typically associated with meta-autunite crystals on matrix.
Nice fluorescent, and a copy of our confirming EDS spectra fro both species is included. Specimens from 1.5cm
to 5cm across @ 15.00, 25.00, 45.00 and 65.00 each, one 13x4x4 speicmens @ 150.00. List alternates!

OPAL-CT- Sidi Lakhdar, Mostaganem Province, Algeria
Odd, somewhat porous beige material completely comprising matrix, typically considered as diatomaceous
earth comprised of opal-CT, implying a cristobalite/tridymite composition. Unusual locality material, ex-A.E.
Seaman Mineral Museum, light-weight specimens about 3cm across @ 20.00 each, with copy of their label.

PIZGRISCHITE- Piz Grisch, Val Ferrera, Graubunden Switzerland
This very rare species occurs as elongated, greyish metallic flattened crystalline aggregates nicely scattered in
matrix, the better specimens with some micro potential as well. Formula: Cu17Bi17S35, monoclinic. IMA #2001-
002. Type locality material from this very difficult to access Alpine locality, and the only locality in the world for
this rariety, eaven 20 years after its discovery! Only a few samples available, sizes from about 1.5cm to 2.5cm
@ 200.00, 250.00 and 300.00 each. First come, first served!

QUARTZ with Inclusions- Sichuan Province, P.R. China
Single crystals of transparent quartz without matrix, most in typical elongated habits and averaging 7 cm tall, all
showing unknown, black inclusions, ranging from numerous dots to filmy internal phantoms. Perhaps
hydrocarbons, Mn-oxides or minute sulfide/sulfosalts, but we have found none at the surface of the crystals that
would enable us to analyze them. Only a few on hand @ 25.00 each.

QUEITITE pseudo @ ALAMOSITE- Lucky Ccss Mine, nr. Tombstone, Arizona
This uncommon mineral occurs here as white spherulitic masses and crusts in and on matrix, apparently as
pseudomorphs after earlier formed alamosite. Old material, specimens range from tiny fragments in a capsule
@ 45.00 to 1cm matrix pieces @ 60.00 each.Limited availability!

QUENSTEDTITE w/ ROMERITE etc.- Mejillones, Antofagasta, Chile
This rare species occurs here as small but excellent violet, glassy aggregates and minute crystals intergrown in
widespread, golden brown romerite, yellow copiapite, a micro, pale blue glassy Cu-sulfate that is NOT krohnkite,
as well as other sulfates. A rather attractive assemblage of colorful and interesting species, these from a find
about 10 years ago. XRD and EDS confirmed, specimens range from about 2.5cm to nearly 6cm across @
30.00, 50.00 and 75.00 each. Attractive assemblage under the scope!

RUIZITE on SUGILITE- Wessels Mine, Kalahari Mn Field, Rep So Africa
Extremely small, glassy brown vitreous crystals of ruizite sparsely scattered on sugary sugilite matrix. These are
small but excellent for the species in the unexpectedly and relatively large crystallized habit! Small matrix pieces
average 2mm to 3mm across @ 35.00 each. Strictly micro material, but interesting under the scope!

RUTILE- Champion Mine, Mono Co., California
Sharp, lustrous single crystals and small groups of deep red-brown rutile, either as floaters or as single crystals
and small groups nicely perched on minor pyrophyllite-rich, buff-colored matrix. Old, classic stuff from many
years ago, we recently located a large lot of good quality mounted thumbnail specimens with crystal sizes
ranging from 0.6cm to 1.7cm across, all in standard TN boxes priced at only 15.00, 25.00, and 35.00 each. Nice!

SCAPOLITE- Puy de Dome, Auvergne-Rhone-Alps, France
This prolific area of France has produced over 225 different minerals, but with scant mention of the scapolite
group or its species members marialite or meionite. We have a couple of old A.E. Seaman Museum samples,
labeled simply as "Scapolite - Puy de Dome" by now-retired curator Dr. George Robinson. They occur as thin
(1mm wide) crystals to 1.5cm long embedded in matrix,certainly interesting for this old locality and worthy of
further research, we think. Specimen sizes average 10x6 cm @ just 40.00 each, only a couple, so list alternates!

SHANNONITE- Tonopah-Belmont Mine, Maricopa Co., Arizona
Fleshy-tan colored masses of this uncommon lead oxy-carboante mineral nicely scattered on rock matrix. We
offer these IMA-approved specimens, originally provided to us by the late Dave Shannon, the mineral namee.
First found here many years ago and originally submitted from this mine, but this was not designated as the type
locality, however. Specimens from 1.5 to 5cm @ 25.00, 40.00, 75.00 and 100.00 each.

SHARYGINITE (IMA # 2017-014)- Bellerberg, Casper Quarry, Eifel, Germany
Repeat of previously soldout material! Another relatively NEW SPCIES from this prolific Rheinland-Palatinate
volcanic deposit, here as minute brown crystalline aggregates scattered in typical Eifel matrix, scattered in
2.5cm polished sections. Formula: Ca3Ti Fe2+Fe3+O8 - orthorhombic, IMA # 2017-014. The Fe-analog of
shulmanite, only one polished sections available @ 195.00.

STIBNITE- Wenshan, Yunnan Province, PR China
From one of the more uncommon loclaities in China for stibnite, we have a few handsome specimens of
essentially single crystals, most slender and singly terminated, measuring from about 10cm to 20 cm tall,
recently featured in teh July, 2021 issue of Mineral News. A small selection on hand from 12cm to 20 cm long @
150.00 and 200.00 each. One monster specimen about 30 cm (!!) tall and 2cm wide, wonderfully terminated and
pictured in the aforementioned issue, at just 1500.00, the largest we have seen from the locality!

STIBNITE- Xikuangshan, Loudi, Hunan Province, PR China
Perhaps the mother of all stibnites from the largest antimony mine in the world: this specimen was also pictured
in the July, 2021 issue of Mineral News, and is certainly the largest stibnite single crystal we have ever offered.
It is a full 43 cm (yes, 17 inches!!) long, quite thick, nicely terminated, and with a slight wavy bend short of the
termination. A few lesser (to 7cm) terminated crystals in parallel growth are present at the base of the specimen,
and this one-of-a-kind giant crystal is net priced at 3500.00. Unique!

TOPAZ- Zapot Pegmatite, Mineral Co., Nevada
Situated in the Gillis Range, the Zapot pegmatite was rich in alumino-fluorides and is the type locality for the
very rare mineral simmonsite. Topaz was perhaps the most attractive species found there, and Harvey Gordon
worked the locality extensively in 1999 and earlier, publishing an excellent article on the locality with Gene
Foord and Art Soregaroliin the Mineralogical Record (Vol. 30, pgs 277-292). This specimen is a single crystal of
transparent topaz collected by Harvey, showing a fine, chisel-shaped termination and sharp prism faces, with
evidence of a smaller twin on one side. A rarely offered locality specimen of high quality, ex-Martin Jensen
Collection, size is 2.5cm x 2.5cm @ 450.00. One only!

VOLBORTHITE- Mitten No. 2 Mine, Navajo Co., Arizona
Small platy crystals of micro, bright yellow-green volborthite lightly scattered on matrix. An uncommon locality
with moderately good micro potential, specimens ranging from about 2.5cm to 6cm across @ 15.00, 25.00 and
45.00 each for these reasonablyattractive specimens.

WALSTROMITE- Esq #7 Claim, Big Creek, Fresno Co., California
Pearly white to colorless disseminated aggregates and exposed seams of this unusual silicate scattered in
matrix. Walstromite is nicely fluorescent (pinkish-orange SW) and therefore readily discernable in these
moderately rich rich specimens. Acquired from mineral namee Bob Walstrom circa 1994, sizes from 2cm to 5cm
@ 15.00, 25.00 and 40.00 each.

WEISSBERGITE- Lookout Pass, Tooele Co., Utah
Micro silvery grey masses of this rare species sparsely scattered in rock matrix, occasionally with micro quartz
and possibly other admixed species such as parapierrotite. Collected by Forrest Cureton and microprobed by
Bart Cannon back in 1995, a single 1cm probe mount with SEM image and chemistry @ 150.00, and the 3cm
matrix sample that yielded the confirming analysis, with arrow, @ 250.00.

WILHELMRAMSAYITE- Koashva Mt., Khibiny Massif, Russia
This rare species occurs as tiny, iron-black platy masses with metallic luster and pronounced mica-like
cleavage, a few possibly associated with minor troilite. Formula: Cu3FeS3*2H2O, orthorhombic, IMA #2004-
033. A very unusual species, not related to any other known mineral! Author's studied material from the only
known holotype specimen, offered as boxed, tiny 0.2mm to 0.6mm metallic platelets @ 185.00 and 225.00
each. When these are gone, that's it, as it remains a one-locality mineral more than 20 years after its discovery!

WOLLASTONITE-2M- Sarabau Mine, Sarawak, Borneo, Malaysia
A rare locality for the mineral, with the uncommon monoclinic 2M structure confirmed by XRD. The mineral
occurs here as small, beige to silvery fibrous needles scattered in bands, associated with a tetrahedrite group
mineral and typical calcite matrix. Previously known as "parawollastonite", collected by Forrest Cureton when he
mined the sarabauite specimens from this off-beat locality decades ago. Only a few specimens on hand, sizes
ranging from about 4cm to 7cm across @ 25.00, 40.00 and 60.00 each.

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, these acquired in 1957. A wide range of
sizes and qualities are on hand, most are neat and inexpensive TN's and miniatures from 1.5cm to 5cm samples
@ 10.00, 15.00, 20.00, 35.00 and 50.00 each. We also have a few larger matrix specimens available up to
1250.00, so please inquire!

WURTZITE- Welkenvaldt, Belgium
These are interesting samples of deep red-brown, semi-metallic wurtzite masses largely comprising matrix,
some with minor pyrite evident in vugs and seams, most showing an odd, wormy to stalactitic morphology,
some with what appears to be reticulated, intergrown galena. Ex-A.E. Seaman Museum material from an rarely
offered older locality! Sizes range from 2cm to 4cm @ only 25.00, 35.00, and 45.00 each.

WUSTITE- Zacatecas, Mexico
A small specimen about 1.5cm across, with lightly scattered pale orange-brown micro fiberous coating on the
reverse side of a crystallized conichalcite specimen. Ex-Cureton, only one available @ 85.00, and not previously
reported for the locality other than in meteoritical specimens.

ZAPATALITE- Cerro Morita, Agua Prieta, Sonora, Mexico
This rare copper phosphate occurs as minute pale blue masses and botryoids in fractures and exposed seams
on matrix, usually with other secondary copper phases. Type locality material originally supplied by the author
some years ago, some with modest micro potential, matrix sizes from about 2cm to 5cm @ 25.00, 40.00 and
55.00 each

CATALOG 22103 – Volume XLVIII, No. 3

AIKINITE- nr. Cucomongo Springs, Esmeralda Co. Nevada
This moderately rare lead-copper-bismuth sulfide occurs as gray metallic striated crystal prisms and masses in quartz matrix. Typical, representative aikinite specimens, occasionally with minor bismutite coatings, available as smallish 1cm to 2cm samples @ 15.00 each, or larger but generally lean matrix specimens from 3.5c m to 6cm @ 25.00, 35.00 and 45.00 each, depending on coverage, not size.

ALABANDITE- Onavas, Sonora, Mexico
Massive iron-black alabandite, with some earthy brown superficial alterations, with minor galena and sphalerite. Quite ugly but representative for this manganese sulfide species from this rather obscure locality. Old material from Dr. Sidney Williams, sizes from 2cm to 6cm @ 10.00, 20.00, and 35.00 each.

AUROSTIBITE- Krasna Hora nad Vitavou, Bohemia, Czech Republic
Silvery grey metallic grains sparsely scattered in ore matrix. The area was mined as early as the 11th century in this Pribram District locality, primarily for gold and antimony, producing over 20 interesting species. Rarely offered material, we have several of these unusual AuSb2 specimens from 2cm to 4cm across @ 20.00, 40.00 and 65.00 each.

BEIDELLITE pseudo @ (???)- Malyi Mannepakhk Mt, Khibiny, Kola, Russia
Dull cream to pale brownish masses of beidellite well scattered in matrix, pseudomorphous after radiating aggregates of an unknown earlier mineral. An obscure locality and uncommon species to add to your pseudomorph collection, only a few specimens available ranging from 2.5cm to 4cm @ just 35.00 and 50.00 ea.

BERYL- Limoges, Haute Vienne, France
An old specimen, ex-John Albanese and Joe Cilen collections, here as a stout, white opaque striated hexagonal crystal with a single pinacoid termination. The specimen is about 6cm tall and 3,5cm wide, sharp in the frontcolunar faces and showing a heavily detached rear. The color is quite odd and from an excellent older European locality, one only at 75.00.

CARNOTITE- Joe Mine, Uravan Dist., Montrose Co. Colorado
This small prospect has gone largely unreported in the literature and is typical of the Uravan Mining District in which yellow carnotite forms thin coatings and masses of yellow aggregates scattered on pale sandstone matrix. There are likely other uranium-rich species here as well, as small amounts of dull green and orange-brown oxidized masses are sometimes present, as is darker corvusite and possibly other vandium-rich phases. From an uncommonly offered locality, specimens range from about 2.5cm to 7cm across at just 10.00, 25.00 and 45.00 each, depending on size and coverage. Mildly radioactive, too!

CLINOCHLORE var: PROCHLORITE- Tilly Foster Mine, Brewster, New York
Old classic material, consisting of pale green hexagonal plates of clinochlore richly scattered on matrix, often altering to a serpentine-like phase. From this famous and now defunct locality, specimens from about 3cm to 6cm across @ 15.00, 25.00 and 40.00 each.

CLINOHEDRITE with HARDYSTONITE- Franklin, Sussex Co., New Jersey
Hand-picked, brilliantly multi-colored fluorescent specimens, but otherwise visually unappealing under normal lightning. These contain willemite, hardystonite, and clinohedrite in an attractive association of green/blue/orange fluorescent responses under SW UV. Similar material is on the market elsewhere at much higher prices, but we have old stock, ranging in size from 2.5cm to 9cm samples @ 20.00, 35.00, 50.00, 95.00 and 150.00 each. Great multi-color fluorescent pieces!

COPPER etc.- Keweenaw Peninsula, Michigan
Much native copper is acid cleaned to dissolve unsightly matrix and expose and brighten the copper itself. These specimens are NOT cleaned, as we suspect some of the rare secondary oxylate or copper minerals may be present in the white, pale green and occasional blue patina films in fracture-filling and surface areas of these rock (literally) specimens with protruding native copper. We can say with some certainty that thin films of cuprite, scant epidote and possibly datolite are here, and each specimen is surprisingly heavy due to the copper content. These are "how it looks coming out of the groud" specimens, and there will be interesting sights under the scope on some of these as well. Overall sizes are about 3cm to 6cm across @ just 10.00, 25.00 and 40.00 each. Neat stuff!

CRISTOBALITE in OBSIDIAN- nr. Black Rock, Millard Co., Utah
Interesting material showing greuyish white star bursts and snow flakes of cristobalite frozen in black, highy vitreous obsidian matrix. Attractive material due to the stiking patterns and color contrasts of the cristobalite in lithiophysae. Specimens from about 4.5cm to 8cm across @ 15.00, 25.00 and a couple @ 40.00 each, collected about 40 years ago!

DRAVITE- Yinniethara, Upper Gascoyne Shire, W.A., Australia
From one of the most prolific, but difficult to reach localities well known for rich, matrix-free dark brown to nearly black dravite crystals! The locality is reached only by four wheeled vehicle over 165 km of dirt roads, and these specimens were acquired in the early 1970s. The crystals are often intergrown and surprisingly large, with a vitreous luster and scant translucency on the root-beer brown thin edges, perhaps the largest well-formed crystals of the species ever brought to market! Single crystals, sizes from equant 2cm specimens to 8cm elongated ones @ 20.00, 35.00, 50.00, 85.00 and 125.00 each. Wonderful stuff!

FERRONORDITE-(Ce)- Palitra Pegmatite, Lovozero, Kola, Russia
From the exceptional pegmatite on Mt. Kedykverpakhk that was featured in Mineralogical Record, we have a few specimens of this great rarity, occurring here as small clusters of 2-3mm pale brown tabular crystals in vugs and seams of microcline and occasionally lomonsovite as well. Author's material, sizes range from about 2cm to nearly 2.5cm across, all with arrows and modest micro potential, at just 145.00 each.

FLUORITE w/ ZnSiO2 INCLUSIONS- Xiangxi, Hunan Province, PR China
As we were slabbing massive green and lightly purple fluorite for our lapiday clients, we noticed several slabs with small, white radiating sprays and sheaves of an unknown mineral. Careful analysis in our SEM/EDS lab indicated that we have found an unusual occurrence of the zinc silicate hemimorphite frozen in the pale green fluorite! We rescued a half dozen unpolished slabs, all averaging about about 11x6 cm in cross section that showed the mysterious white sprays, and we can supply each with a copy of our SEM/EDS analysis, at just 20.00 per slab. Odd stuff!

GLAUCOPHANE- Mt. Vodno, Skopje, Macedonia
From a small find anout 15 years ago at this uncommon locality, we have a few samples of glaucophane occurring as dark blue prismatic aggregates to 0.5cm long, frozen in quartz matrix, typically with minor calcite and/or greenish mica. Microprobe confirmed, specimens average about 3.5cm @ just 25.00 each.

GOLD with COLORADOITE- Bessie G Mine, La Plata Co., Colorado
Tiny flecks of native gold sparsely scattered in quartz matrix, typically with greyish metallic coloradoite and possibly other tellurides. Magnification will be needed on these, but good reference material for this excellent Colorado locality, all specimens with arrows. Matrix sizes range from about 1.5cm to 3.5cm @ 25.00, 35.00 and 45.00 each.

GROUTITE- Zavalie Deposit, Kirovograd, Ukraine
Perhaps the world's finest occurrence of the mineral, offered here as remarkable encrusted, tabular, divergent crystal groups to 1cm across (!!) perched in exposed veinlets and vugs. The material is spectacular for the species, as ubiquitious groups 1-5mm in rich botryoidal coverage or as isolated larger balls, all with strong vitreous to submetallic luster as well! Quite extraordinary for the species, matrix sizes from about 2.5cm to nearly 5cm across @ 50.00, 85.00 and 125.00 each. Truly the best we have ever offered!

HARRISONITE- Arcedeckne Island, Nunavut, Canada

MONTROYDITE etc.- Clear Creek Claim, San Benito Co., California
Dark reddish brown to nearly black prismatic micro crystals of this uncommon mercury mineral on quartz matrix, occasionally with minor cinnabar, mercury or other obscure Hg-rich species. The better samples will yield decent micros, with others more typical reference samples, sizes ranging from about 1.5cm to 3cm across @ 20.00, 40.00 and 55.00 each, depending on quality of crystallization, not necessarily size.

NALIPOITE- Mt. Kedykkvekpakhk, Lovozero, Kola, Russia
This rare species, named for its chemical composition (Na-Li-Phosphate), occurs as small (1mm) transparent blocky masses without matrix. Only the second world occurrence when found at Lovozero, we have just a few boxed samples of this rarity @ 160.00 each. 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 nearly 4cm across @ 20.00, 35.00 and 55.00 each, depending on size and coverage.

OMPHACITE- nr. Occidental, Sonoma Co., California
This uncommon mineral occurs as greenish, fine-grained masses densely comprising matrix, often with numerous micro red garnets dusted throughout some areas on the larger samples, likely qualifying as an ecloglite.

STANNITE on FERBERITE- Yaogangxian Mine, Hunan Province, PR China
A classy thumbnail showing sharp, brassy stannite crystals to 1cm perched atop a nearly black ferberite crystal group forming the base of the specimen. The locality has produced world-famous examples of stannite, bournonite and arsenopyrite, and this TN is certainly among the best, acquired in 2004 in Changsha before most of the world had even seen great specimens from the mine! Overall size about 2.5 x 2cm @ 525.00. One only! A few extraordinary cabinet specimens from other mines in China are available - please inquire!

TANTALITE-(Mn)- Ognevka, Ulan, Kazakhstan
An excellent, flattened tabular crystal from this Ta deposit in eastern Kazakstan! Nicely striated, deep reddish-black crystal group without discernable matrix, overall about 3.7cm x 3.5cm, great locality piece @ 150.00.

TORBERNITE- Black Pine Mine, Granite Co., Montana
This new discovery of torbernite on older specimens will be featured in the June, 2021 issue of Mineral News. The tiny, pale green plates are often associated with micro brochantite crystals, but always on a bed of terminated quartz crystals coating with pale green secondary phases. Only five specimens are known to exist, and we have them all, each accompanied by a copy of our analytical work that confirmed the mineral. A unique occurrence, specimens range from about 3cm to 5cm @ 150.00 and 200.00 each; one 8x5cm sample with multiple crystals @ 350.00. List alternates!

URANINITE- Bicroft Mine, Haliburton Co. Ontario Canada
Exceptionally large masses of Bicroft mine uranium ore, the mine once the second largest uranium producer in the rich Bancroft area before closing in 1963. We have a pair of extraordinarily rich and heavy specimens, each with a cut face that measures about 15x12 cm in cross section and depths varying from about 9 cm and weighing about 7 pounds each! The uraninite forms black pods and veins richly scattered in matrix, and our Geiger counter screams at these! These are certainly from the same boulder, as the cut faces match quite well, collected by H. Rozenbroek sometime prior to 1991. A very large box will be needed for shipping these beasts, available for 695.00 respectively, plus shipping. Hot!

VESIGNIEITE- Sombrero Butte, Pinal Co., Arizona
Dull, olive green masses of poorly crystallized vesigneite very sparsely scattered on a weathered quartz monzonite matrix, occasionally with other trace copper minerals. Rather ugly and lean, but from an interesting locality collected by Forrest Cureton over 50 years ago and subsequently XRD verified by Dr. Sidney Williams in July, 1972 (yes, we have his XRD data, too). The precise locality in this Bunker Hill/Copper Creek area in the Galiuro Mountains is likely one of the unnamed prospects cited in Minerals of Arizona that sits about midway between Phoenix and Tucson. Specimens range from 2.5cm to 6cm across, all with lean coverage, priced at just 10.00, 15.00 and 20.00 each.

Sizes from about 1.5cm to 2cm @ 75.00 each, with modest micro potential.

CHRYSOCOLLA with TENORITE- near El Mezquital, Sinaloa, Mexico
A mystery locality, heretofore unreported in the literature as far as we can tell! Sometime prior to 1960, Robert Winstead supplied this material to a Rialto, California rock shop owned by the father of Mineral News Contributing Editor Bob Werner. Winstead had driven a 50' adit at the Herules Mine in Ramona, California in 1954, perhaps his only claim to fame beyond supplying interesting minerals to local rock shops of the day. The material is comprised of pale blue botryoids of chrysocolla, some overlaying radiaiting splinters of micro aurichalcite, and often topped off with small, black vitreous aggregates of tenorite as well. Unique and previously unstudied material more than 70 year old, specimens from about 4cm to 7cm @ 15.00, 25.00 and 40.00 each. We continue to research for more details!

COLORADOITE- Bessie G Mine, La Plata Co., Colorado
This uncommon mercury telluried occurs as greyish metallic masses thinly scattered in quartz matrix. The locality has produced over 30 different species, including many gold and silver tellurides. These are relatively lean specimens, and magnification will help, but satisfactory reference material for the locality. Matrix sizes range from about 1.5cm to 3.5cm @ 15.00, 30.00 and 40.00 each, depending on quality/coverage.

COLUMBITE-(Fe)- Steidler Pegmatite, Chester Co., Pennsylvania

DIAMOND- Bandama River, Hambol Region, Ivory Coast
Long known for diamond production, the ban on rough diamond export from the Ivory Coast was lifted in 2014. We have several good crystals available, most as gemmy, pale tan, transparent dodecahedrons averaging about 1.14 carats each, matrix free, of course, and quite attractive. Sizes are typically around 6x4mm @ just 145.00 each. Nice!

ESKOLAITE @ MAGNESIOCHROMITE- Clear Creek Claim, San Benito Co., Californi
Tiny, highly vitreous dark green to nearly black anhedral grains of this uncommon chromian analog of corundum, hematite and karelianite replacing magnesiochromite pods in a highly silicified serpentine matrix. You'll need magnification on these samples, but all have arrows to pinpoint the mineral. An uncommon pseduomorph and inexpensively priced, sizes from about 1cm to 2.5cm @ 15.00 and 20.00 each, depending on quality.

FALCONDOITE- Falcondo Mines, Bonao Dominig, Dominican Republic

FALSTERITE (IMA 2011-061)- Estes Quarry, Baldwin, Cumberland Co Maine
Discovered nearly twenty years ago but lying fallow until recently characterized from here and Palermo, the relatively new and rare phosphate species, falsterite occurs as tiny, bluish green, micaceous aggregates sparsely scattered on matrix, occasionally with minor sphalerite, brown schoonerite etc. Formula: Ca2MgMn2+2Fe2+2Fe3+2Zn4(PO4)8(OH)4(H2O)14, monoclinic, IMA #2011-061. Our Estes material has a slightly higher Zn and lower Mn content, but was confirmed by the senior author as otherwise identical to the Palermo material. Named for Al Falster, well known researcher and collector. This is the very last of the available material, ex-Gene Bearss, as no additional specimens have been found at the locality! We have a very few specimens, all accompanied by a copy of our analytical work, ranging in size from about 1cm to 1.5cm across @ 200.00 each.

GOLD with SERICITE- Round Mountain Mine, Nye Co., Nevada
This specimen was part of a small lot that was collected in 1993 from the 9000N, 11400E, 6445 bench of this famous mine. The specimen consists entirely of tightly intergrown spinel twins and tiny octahedra of native gold, with minor sericite underneath. Analysis at the time showed a 70:30 Au:Ag ratio, overall size about 2cm tall and 1cm wide @ just 650.00, less than two times spot typical for crystallized gold!

HALITE- Salton Sea, Imperial Co., California
A recently discovered crate of large, massive to cubic halite specimens, collected and bagged sometime in the distant past, all showing typical colorless, transparent to translucent diaphaneity. Surprisingly preserved and oversized specimens from about 5cm to 9cm blocks @ just 15.00, 30.00 and 45.00 each, with one 15x12x10cm monster @ 95.00. Don't put them in your fishtank!

Unusual, brown-skinned, hard nodular ball-like masses of what is essentially a carbonate fluorapatite mixture, here as rounded, matrix free "phosphorite" balls. These unique mineralogical oddities have an interesting history, as they were once gathered by troops in Peter the Great's victorious Great Northern War of 1708 and used as canon balls in the Battle of Lesnaya by the Russians! These are solid and unopened nodules that internally consist of dense, radiating material taht we unilaterally decided to call them by their original name, phosphorite. Historical, and very hard, nasty little things (can't image getting hit in the head with one!), sizes range from about 2.5cm to 3cm across @ 65.00 each. Only a couple available.

PYROPHYLLITE- Hickory, Catawba Co., (?) North Carolina
Old material from this prolific state, first acquired in 1957 and offered here as excellent, radiating masses of beige to golden-hued radiating pyrophyllite comprising matrix. The locality is suspect, I think, as there are many pyrophyylite localities in North Carolina, but none in Catawba County. The material closely resembles those from Troy (Montgomery Co.,) or Snow Camp (Alamance Co.,), but we are unable to confirm either despite the strong resemblance. Specimens range from about 4cm to 6cm across, priced inexpensively at just 10.00 and 15.00 each.

QUARTZ var: AMETHYST "Grape Agate"- Mamuju, Sulawesi Barat Province, Indonesia
A few more of these fascinating specimens from the 2016 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 monster 28cm across with varying heights and depths, priced very reasonably at just 35.00, 50.00, 85.00, 150.00, 300.00,

This is a new structural type, IMA #2010-017, formula: CaMgFe2+Al9O16(OH), monoclinic. From the type locality in the Tashelginskoe Fe occurrence within the Kemerovo Oblast, we have only a few specimens averaging about 1cm across, all with arrows, at 95.00 each. Don't miss these!

VESUVIANITE- Zulova, Olomouc Region, Czech Republic
An old specimen, comprised of elongated, striated vesuvianite crystals to 3cm tall and 1.5cm wide, extending from a massive vesuvianite and carbonate matrix. Ex-Czech Nation Museum and accompanied by a their label plus an older German language one of unknown provenance. The vesuvianite is dark greenish brown with glassy prism faces and one modest pinacoidal termination among the aggregates. A rarely offered locality piece, overall size about 7x4 cm @ 75.00. One only!

VIVIANITE- Mt. Cleveland Mine, Luina, Tasmania
Strange, slender glassy prisms of deep blue-grey vivianite without matrix, some showing odd curved and twisted habits. Very unusual for the species, from an obscure locality and quite unique. Collected over 25 years ago, these weird singles range from about 1.5cm to nearly 3.5cm long(!!), priced at 15.00, 25.00, and 40.00 each.

WELOGANITE- Francon Quarry, Montreal, Quebec, Canada
Typical "pagoda-shaped" hexagonal prismatic crystals of weloganite, having highly stepped and perpendicularly striated prism faces. This strontium zirconium carbonate occurs as translucent yellow crystals up to 1 cm, most smaller, some with a white powdery coating. Old material, nicely crystallized, only a few on hand, 3.5cm to 6cm matrix sizes @ 40.00 and 50.00 each, one larger 8cm specimen with larger crystal @ 95.00.

WINDHOEKITE- Aris Quarry, Windhoek District, Namibia
This relatively new mineral occurs here at the type locality as excellent, micro needles in radiating sprays perched in vugs in rock matrix, all with a golden brown hue and very attractive under the scope. We analyzed a large number of tuperssuatsiate samples we had in stock (all visually indistinguishable from this species!) and found only five (5) specimens that were this new, Ca-dominant member. We can offer the samples of analyzed needles, several adhered to our SEM stub and accompanied by their numbered confirming chemical analysis @ 125.00 per sample stub. If you plan to purchase the mineral elsewhere, be
sure to have its specific chemical analysis included, as there is no apparent difference in X-Ray pattern or physical appearance between this species and the more common tuperssuatsiatite. Caveat emptor!

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!

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.

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
Fine micro sprays of white, tufted crystal groups of makatite scattered in vugs in matrix, some associated with other interesting species. Another species from this prolific area, matrix sizes from 2cm to 4cm @ 25.00, 40.00 and 55.00 each depending on quality.

OLIVENITE- Majuba Hill, Pershing Co., Nevada
From the finest U.S. occurrence, these are very dark green, elongated olivenite crystals to 5mm long(!!) richly scattered on exposed seams on matrix. Excellent for the species, these are hand-picked, wonderful small groups as matrix specimens from 2.5cm to 8cm @ 10.00, 17.50, 25.00, 40.00 and 75.00 each, all with micro potential as well.

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? Specimens range from about 2cm to 4cm across @ 125.00, 150.00 and 175.00 each, depending on overall quality and size.

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. First come, first served on these old, handselected specimens screened out from our large purchase years ago!

Large, flattened platy aggregates of brilliant, black hematite crystals to 3cm across form an 8cm mass, interspersed with dull pinkish rhodochrosite (XRD and EDS confirmed), perched over massive quartz. This hefty specimen came by way of Dr. George Robinson while at Michigan Tech as he analyzed and culled
many thousands of duplicates from the A.E. Seaman Museum collection and its subsequent donations. An interesting but not terribly pretty specimen, overall size about 10x6cm @ 55.00.

HOWLITE- Sterling Mine, Tick Canyon, Lane, California
Greyish white botryoidal masses and chalky aggregates of howlite comprising these nodular specimens. Often dyed and sold as spiderwebbed turquoise to unsuspecting tourists, we have a small supply of older material, sizes averaging 2cm to 5cm @ 5.00, 10.00 and 20.00 each.

JORDANITE var: GUITERMANITE- Zuni Mine, Silverton, San Juan Co., Colorado
Rich, metallic grey masses of "guitermanite" impregnate the matrix of this old material from the type locality for "guitermanite". The material is well documented after many conflicting identifications, and it is now considered identical to jordanite, a Pb-As-Sb sulfide, likely with admixed baumhauerite or other phases. Old material, overall matrix sizes from 1.5cm to 3cm @ 10.00, 20.00 and 35.00 each.

There is minor quartz and other non-descript associations that perhaps a Maine specialist might recognize, overall size about 8x5cm @ 40.00, with labels. One only

SILLIMANITE- Val di Fassa, Trentino-alto Adige, Italy
An excellent, old specimen, originally acquired by L.L. Hubbard (1849-1933), former state geologist, mining engineer and collector who's calcite collection was extensively illustrated by Palache in his 1898 paper re: Michigan calcites. The piece shows virtually pure, thin greyish needle-like crystals of sillimanite comprising the top surface of this 8x6cm piece! Hubbard's collection went to the A.E. Seaman Museum, and this specimen is accompanied by the Museum's label @ 65.00. One only!

SPINEL var: PLEONASTE- That Nam Penh, Thailand
An obscure locality for these black, iron-rich spinel octahedral without matrix. Good forms that are slightly waterworn due to alluvial action, and all are without matrix. We have been unable to verify a more precise locality for these Fe-rich spinels, sizes average about 1cm @ just 12.50 each.

STRONTIOJOAQUINITE- Mina Numero Uno, San Benito Co., California
This uncommon mineral occurs here as minute, somewhat blocky tan to yellowish crystals sparsely scattered on pale blue crosstie matrix, typically with minor neptunite and possibly other minerals.

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!

CALCITE (FL & PHOS)- Wenshan, Yunnan, PR China
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. These are transparent to translucent and have a subtle, pleasing greyish-white huer. Quite exceptional when compared to the more typical blocky white specimens, these are very aesthetic and yet reasonably priced, sizes from about 2.5cm to 10cm across @ 8.00, 15.00, 25.00, 40.00 and 55.00. A few larger available - inquire! 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

We have several good crystals available, most as pale tan, transparent dodecahedrons averaging about 1.14 carats each, matrix free, of course, and quite attractive. 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.

EDGARITE- Mt. Kaskasnyunachorr, Khibiny, Kola Russia
This rare species occurs as minute (1mm) greysih metallic plates sparsely scattered as epitactic overgrowths on pyrrhotite in greyish alkaline hornfels rock matrix.

EUCRYPTITE- Parker Mtn. Mine, Center Strafford, New Hampshire
Beautifully fluorescent material! These non-descript grayish specimens are brilliantly fluorescent when illuminated with SW UV light, the eucryptite giving a bright deep red response, and occasional secondary uranium minerals giving a bright green response, resulting in an eye-poping combination! Most of these are from Jack Baum's ("baumite", johnbaumite) fluorescent collection, in sizes ranging from 2cm to 8cm across at just 8.50, 15.00, 25.00, and 40.00 each.

EVSEEVITE with POLYARSITE- Arsenatnaya fumerole, Tolbachik, Russia
These two NEW SPECIES occur together from this prolific volcano, so all samples offered will have both species present. The evseevite (Na2Mg(AsO4)F, orthorhombic, IMA # 2019-064) presents as minute, colorless to pale pinkish acicular needles, associated with bright blue microscopic polyarsite
(Na7CaMgCu2(AsO4)F2Cl, monoclinic, IMA # 2019-058) sparsely scattered on the matrix. Evseeite is named for Russian mineralogist Aleksandr Andreevich Evseev (b. 1949), and polyarsite is named for the many (poly) ordered species-defining metal cations and the two halide anions. 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. First come, first served on these old, hand-selected specimens screened out from our large purchase years ago!

GALENA etc.- Elmwood Mine, Smith Co., Tennessee
A monster specimen comprised of a large, crystallized galena mass that measures about 11x7x7cm, showing excellent stepped faces, embedded at the edge of a greyish white, dolomitic limestone matrix that sports several small areas of a massive, pale purple fluorite vein assemblage on the opposite end from the
galena. Acquired from a miner's stash over 20 years ago when these extraordinary samples were simply called "leads" by the locals. A very heavy specimen that weighs over 10 pounds(!!) and measures about 17x11x7cm @ 325.00. One only!

HYDROXYAPOPHYLLITE-K- Goose Creek Quarry, Leesburg, Virginia
From one of the more famous Loudon County quarries, these are exceptional, transparent to translucent tabular hydroxyapophyllite-K crystals with little or no matrix, these fairly old and collected from the type locality for both loudonite and goosecreekite. Crystal sizes range from groups of 1cm singles forming 3cm specimens, up to single tabular crystals to 4cm+. Inexpensively priced for the quality of these excellent specimens, all mounted on clear leucite bases @ 30.00, 45.00 and 60.00 each.

KARPATITE- nr. Picacho Peak, San Benito Co., California
Excellent, elongated bright yellow needle-like crystals and aggregates of brilliantly fluorescent (sky0-blue both SW and LW) karpatite scattered on matrix, occasionally with minor quartz or other species. Some with micro potential and all quite representative for this unusual hydrocarbon species. Ex- Jack Baum fluorescent collection, matrix sizes from about 2cm to 5cm @ 20.00, 30.00 and 45.00 each, a few larger to 10cm @ 75.00 and 100.00 each, depending on coverage!

KATIARSITE w/ BADALOVITE- Arsenatnaya fumerole, Tolbachik, Russia A pair of rare species from this famous Kamchatka volcano! Katiarsite (IMA 2014-025) occurs as colorless to white, tiny acicular crystals lightly scattered on white sanidine matrix, associated with minute, pale bownish sheaves of badalovite (IMA 2016-053) as well, occasionally with minor black hematite. Quite nice under the scope with fine micromount potential. Only a few small specimens on hand, sizes in the 5mm to 1cm size range, offered at 195.00 and 250.00 each, depending on quality, not matrix size. Type locality, of course, for both species, and author's studied material.

MACDONALDITE- Esquire Claims, Rush Creek, Fresno Co., California
Many sparkling tiny cleavage faces of satiny, needle-like macdonaldite are embedded in a grey-white matrix in these samples from the type locality for this species. This Macdonald did not have a farm, but rather was a well–known volcanologist for whom the mineral was named in 1965. 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
This extremely rare species occurs as white, somewhat pearly flattened masses and crusty aggregates scattered on dolomite matrix, many associated with the new species bakhchisaraitsevite. These rare, sodium-strontium phosphate specimens are from the second locality for the species. Small, pure fragment in
a capsule @ 35.00 each.

NICKELSKUTTERUDITE- St. Andreasberg, Harz, Germany
This uncommon mineral occurs here in greyish metallic masses richly scattered in and comprising matrix, some with small micro crystals of this chloanthite variety as well!

Obtained in a museum exchange many years ago, only a few specimens on hand, sizes from 1cm to 5cm across @ 25.00, 50.00 and 85.00 each; one 8x5cm specimen @ 150.00.

PYRITE (Weird!!)- Bargers Quarry, Lexington, Virginia
Perhaps the most interesting pyrite crystals to be found: excellent octahedral single crystals with off cube faces, some showing converging striations due to twinning. 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!

RANCIEITE- Mont Mirat, Lozere, Occitanie, France
Old BRGM material obtained from Dr. Paul Sainfeld many years ago, comprised of brownish black, somewhat iridescent masses scattered in thin exposed veinlets in limonitic ore matrix. Specimens range from about 2cm to 4cm across @ just 20.00, 30.00 and 45.00 each.

RANSOMITE w/ LAUSENITE etc.- United Verde Mine, Jerome, Arizona
Exceedingly rare and impossible to obtain today, these were collected by Carl Lausen (lausenite) in 1928, immediately after the mine fire that likely formed the mineral. Ransomite occurs as very sparse, pale bluecrystalline masses scattered through a friable matrix of lausenite aggregates, occasionally with orangebrown butlerite and possibly other phases such as yellowish guildite(?). Type locality material. We have only a few specimens available, these as tiny grains in a 2.5cm screw-top vial @ 45.00. Old, classic material!

TEALLITE with WURTZITE- Carguaicolla Mine, Potosi Dept., Bolivia
Broad, silvery metallic foliated masses of teallite scattered in matrix, some specimens associated with redbrown, granular wurtzite or potentially with other species. From one of the few sulfide deposits mined for tin, these were collected in 1999 at the mine and only recently found again in the warehouse. Specimens range from about 2cm to 4cm, dense and heavy, @ just 15.00, 30.00 and 45.00 each.

TOPAZ- Schneckenstein Cliff, Saxony, Germany
From an old hoard of Ward's Natural Science specimen, the topaz on these speciemsn occurs as tiny prismatic crystals scattered on a greissen matrix.

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!

CALCITE- La Junta, Otero Co., Colorado
From an unusual locality, we uncovered an old hoard of calcite crystals on matrix, offered in two distinctive habits. The first shows sharp rhombohedra to 1.5cm richly scattered attractively on matrix, the second as somewhat flattened, tabular stacked crystals. The rhombic samples range 4cm to 7cm across @ 10.00, 20.00 and 35.00; the mushroom shaped from 3.5cm to 5cm @ 15.00, 25.00 and 40.00 each. Old stuff!

CHALCEDONY pseudo @ SPONGE- Bu Craa, Laayoune-Sakia El Hamra, Morocco
Weird chalcedony psedomorphs after fossil sponge colonies, here as greyish white, knobby botryoidal aggregates replacing the larger sponges, and occasionally with darker brownish nodules of smaller sponges growing with the larger ones. These are also nicely fluorescent (orange, better LW than SW) and show no discernable matrix from the phosphate mines that yielded these 100+ million year old fossil replacements. Sizes range from about 3.5cm to 5cm across at just 15.00 and 25.00 each. Very neat stuff!DANBURITE- Chapare Province, Bolivia Individual single floaters of danburite crystals, doubly terminated with a grey, frosty translucent color and luster. Specimens aveage about 2cm tall, are relatively clean, and are priced at just 15.00 ecah. Only a few available
from this older find.

DEFERNITE- Kombat Mine, Grootfontein, Namibia
Interesting specimens of deep red, platy defernite with nearly a metallic luster, lightly scattered in a black hematite/hausmannite matrix. Quite different in appearance from the type locality material, this defernite is passably attractive despite its small size! A moderately unusual species, matrix from 1cm to nearly 4cm @ 20.00, 40.00, 60.00 and 95.00 each.

ELPIDITE w/ ARFVEDSONITE- Khan-Bogdinskii Massif, Gobi, Mongolia

Nice representative specimens from the distant Gobi Desert, in sizes from 2cm to 5cm, reasonalbly priced at just 15.00, 25.00, and 40.00 each.

GYPSUM (FL SW & LW)- Patillas Hill, Zaragoza, Aragon, Spain
Attractive, pale pinl massive gypsum from the alabaster quarries here, these are quite compact and dense, showing brilliant red-orange fluorescence under both SW and LW UV! Quite striking under the UV lamp, these are from the collection of the late John L. Baum (johnbaumite), N.J. Zinc's chief geologist at Franklin and a former curator at the Franklin Mineral Museum. Rich, solid specimens, sizes range from about 3cm to 8cm across @ just 8.50, 20.00 and 40.00 each. Brilliant FL material!

HAMBERGITE- San Pedro Mine, Ramona, California
Old specimens comprised of single crystals and sections of hambergite without matrix, these typically a pale buff color and showing somewhat flattened prism habit. Mildly fluorescent. Specimens from 6mm to nearly 20mm @ 35.00, 55.00 and 75.00 each, often used to confound SEM/EDS users because of its chemistry.

HAUSMANNITE- Langban, Varmland, Sweden
Old specimens, ex-Burminco and Cureton, showing greyish black micro crystals and massive, disseminated aggregates of hausmannite nicely scattered in calcite core matrix from this famous locality. The specimens measure about 3cm to 6cm across @ 20.00, 30.00 and 45.00 each.

INGODITE- Tyrnyauz Deposit, Kabardino-Balkaria Russia
This rare bismuth-tellurium sulfide mineral was first described in 1980 from Russia, and it occurs in a over a dozen countries, but few specimens have been available due to paucity of confirmed samples. We have a pair of microprobed specimens, complete with SEM backscatter images and chemistry, each as a small grain mounted in a 2.5cm probe mount at 165.00 each. A nicely documented rarity!

JONESITE on CROSSITE- Gem Mine, San Benito Co., California
Excellent micro crystals of very tiny radiating flattened transparent jonesite sparsely scattered on greyish blue crosstie matrix, some with minor natrolite. Larger samples occasionally with minor crystallized neptunite or joaquinite and/or other species. Matrix sizes from 1.5cm to 5cm @ 55.00, 75.00 and 90.00 each, depending on quality and associations, not size. Some samples with good micro potential as well.

LLANTENESITE (IMA 2018-011)- San Pedro Mine, La Rioja Prov., Argentina
This NEW SPECIES occurs as minute, glassy pale blue crystals, offered here as a portion of the holotype specimen! Formula: Cu6Al[SeO4](OH)12Cl*3H2O - trigonal, IMA # 2018-011.

STIBNITE with FLUORITE- Chiang-Mai Province, Thailand
Acquired over thirty years ago from an unnamed fluorite quarry, and mentioned briefly in a 1987 MinRec note, this are weird stibnite specimens, typically with small needle-like metallic crystals to several millimeters, lightly scattered in exposed seams and vugs in dense rock matrix. Curiously, clear to grayish fluorite, in minute balls,tiny crystals and occasionally massive, are scattered about the specimnes, sometimes investing the stibnite as seen through the 'scope. Old stuff uncovered in our warehouse, only a few specimens on hand, sizes ranging from 5cm to 8cm @ just 55.00 and 75.00 each, more strangely unique than attractive.

TETRAHEDRITE (Zincian) & QUARTZ- Sweet Home Mine, Alma, Park Co., Colorado
Known for its astounding rhodochrosites, this mine had produced some fine sulfide minerals as well, these being greyish black zincian tetrahedrites perched among slender, elongated quartz crystals. Analytical work has shown this material to grade towards tennantite in some samples, and associations may also include pyrite, sphalerite and other phases. These are reasonably attractive and quite inexpensive, specimen sizes from about 3cm to 6cm @ 12.50, 20.00, 35.00 and 50.00 each, priced according to quality. (IMA proposal recently accepted may designate this material as the newly defined tetrahedrite-(Zn), but we await formal publication)

TOPAZ- Schneckenstein Cliff, Saxony, Germany
From an old hoard of Ward's Natural Science specimen, the topaz on these specimens occurs as tiny prismatic crystals scattered on a greissen matrix. The locality, situated on Kielberg Mountain, is noted in many old mineralogical literature classics, as well as mentions in Mineralogical Record several times. Impossible to collect today, matrix sizes range from about 2.5cm to 5cm across, many suitable for micromounting, offered at just 15.00, 25.00 and 40.00 each.

Coverage is quite good, and crystals reach over 1cm on larger specimens; matrix sizes from 2.5cm to 8cm @ 15.00, 30.00, 45.00 and 65.00 each. Excellent material from an older occurrence!

WAVELLITE- Gold Quarry Mine, Eureka Co., Nevada
Excellent and unusual microcrysals of wavellite. These rich specimens externally look like pearly to silky pale green wavellite spheres, to several mm's, on matrix, but are actually composed of sharp radiating tufts of transparent microcrystals, some with possible fluellite, volborthite, hewettite, etc. Moderate to good coverage, from about 2cm to a whopping 12cm @ 10.00, 20.00, 40.00 and 65.00 each for the largest. Older stuff from the late 90's, only a few available in each size range, please list alternates!

CATALOG 21907 – Volume XLVI, No.7

ANORTHITE var: LABRADORITE- Ylamaa, South Karelia, Finland
Collected over thirty years ago from the "spectrolite" quaries in Finland by Dutch mineral dealer H. Rosenbroeck, these are unpolished, rough granitic samples very richly comprised of anorthite feldspar (variety labradorite), some showing minor flashes of the "spectrolite" for which the locality was so well known. Color on these is typically greyish and unappealing before polishing, but the locality in the Fennoscandian Shield is the attraction in these relatively large specimens, sizes from about 5cm to 15cm across, offered at just 10.00, 20.00, 40.00, 55.00 and 75.00 each based on size/weight. Classic stuff!

ARSENOWAGNERITE (IMA #2014-100)- Arsenatnaya Fumerole, Tolbachik, Russia
This relatively NEW SPECIES occurs as minute, pale yellow, crude tabular micro crystals and grains from 0.2mm to nearly 1mm in size from this famous Kamchatka volcano. These are from the type (and only) locality for this new magnesium fluoroarsenate mineral, formula: Mg2(AsO4)F, monoclinic, IMA #2014-100. Exceptionally rare, named for the arsenate analog of wagnerite, either as very tiny grains mounted on adhesive on 1cm disks @ 125.00, or as larger crystals in matrix sizes from 1cm to nearly 2cm @ 195.00 and 250.00 each, the latter two with modest micro potential as well!

ASTROPHYLLITE- Skutesundskjaer, Langesundfjorden, Norway
Flattened aggregates of bladed, brown astrophyllite lightly scattered in pale feldspar matrix, these from the wellknown Barkevik area in Vestfold. Collected mnay years ago, matrix specimens range from about 3cm to 6cm across @ 10.00, 20.00 and 30.00 each, depending on size & coverage.

BERYL var EMERALD w/ PYRITE- Chivor Mine, Boyaca Department, Colombia
A pair of interesting emerald specimens, here as tranlucent green hexagonal crystals and sections to 1.5cm on matrix, associated with small pyrite crystals typical for the locality. Each sample measures about 6x5cm to 8x5cm, and multiple emeralds are on the surface of all of these small hand specimens @ 250.00 and 300.00 each. List alternates!

BETAFITE- Ambotofotsy Pegmatite, Itasy, Madagascar
A rather large and well-formed single crystal of this pyrochlore supergroup mineral (var: betafite, of Hogarth 1977), showing large octahedral faces over 2.5cm tall and the typical yellowish-tan alteration throughout. Originally from the Museum National D'Historie Naturelle in Paris, and accompanied by their old label, the specimen is an excellent example of the large betafites the locality produced. Ex-Rosenbroeck Collection #3840, the specimen is very hot and measures about 4x4x3.5cm @ 250.00. One only!

BROOKITE on QUARTZ- Magnet Cove, Hot Spring Co., Arkansas
Many tiny, crude black octahedrons to several millimeters and occasionally larger masses of brookite richly scattered over crystals and aggregates of grey quartz and rock matrix. Classic U.S. locality for the species, collected in the 1960's by Ted Morely (then owner of Piedmont Minerals of Virginia), with overall matrix sizes ranging from about 2.5cm up to 8cm @ 10.00, 20.00, 30.00, 45.00 and 60.00 each, priced strictly according to quality and coverage of the brookites.

BYSTROMITE- La Fortuna Mi., Agua Prieta, Sonora Mexico
A decidely ugly mineral, here as rather pale, greyish tan masses and veinlets scattered on matrix, typically with secondary copper minerals. Very ugly but very uncommon as well, old Sid Williams material collected from the El Antimonio District in the 1970's, specimens from about 2cm to 6cm @ 15.00, 25.00, 45.00 and 60.00 each.

CALCITE (FL)- Santa Eulalia, Chihuahua, Mexico
Small "spikes" of needle-like calcite spears richly scattered on massive calcite matrix, many showing blue-white fluorescent under SW UV, and an unusual peach colored response under LW UV. A few will even phosphoresce briefly after SW saturation. Old material acquired in 1971, good micro and fluorescent response, very inexpensively priced, sizes from about 2.5cm to 10cm across @ just 4.00, 7.50, 12.50 and 25.00 each. Smaller samples generally show better fluorescence, large ones generally more botryoidal in habit.

CYANOTRICHITE- Peacock Mine, nr. Leadore, Lemhi Co. Idaho
Attractive, medium blue fuzzy balls and micro tufts of cyanotrichite nicely scattered on matrix, originally acquired in the 1960s from this obscure locality. Visits to the area more than 20 years ago found no secondary copper minerals remaining from this small mine. Colorful, neat older material, much with micro potential as well, specimens from 2cm to 3cm across @ just 12.50, 20.00 and 30.00 each, depending on quality.

DAVREUXITE- Ottre, Luxembourg, Wallonia, Belgium
This uncommon mineral occurs as white, pearly, fibrous masses in/on matrix, occasionally with massive quartz. The type locality (Ottre), as well as several others, are all noted as within Vielsalm area, either as small, separate population centers or sub-muncipalities of Vielsalm. Many have attributed davreuxite occurrences, most in the general area of the slate quarries. Specimens are ex-University of Liege, as well as several others, and sizes range from about 2cm to 7cm across, offered at just 15.00, 25.00, 40.00, 55.00 and 75.00 each.

ESPERITE- Franklin, Sussex Co., New Jersey
From an old hoard, we have a small selection of interesting esperite specimens, most with typical willemite associations, some with zincite or other phases. 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

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. The author was the curator of Earth Sciences at the British Library, and the contents provide an overview of rocks, minerals, chemistry, identification techniques and more, complete with a bibliography, glossary and index. Specimen images are from superb, world-class specimens in major
museums and private collections, with many contributing organizations such as Harvard, Michigan Tech, Smithsonian and others. As new, just $35.00.
New York State Museum Report of 1911: The Eurypterida of New York
This is a bound hardcover work of the Appendix 5 of the Museum Memoir No.14 that carries all the plates of this New York eurypterid magnum opus, including the huge fold outs that measures almost three feet tall and nearly two feet wide! The 88 plates are interleaved, and they are likely the best illustrations and descriptions of the eurypterida of New York, the state fossil. A large, heavy book originally acquired from a French library, the bound volume is a
likely a unique presentation format. One only @ 125.00
American Mineral Treasures – Edited by G. Staebler and W. Wilson
A monster hardcover book of 354 pages, handsomely illustrated throughout with full color images of some of America’s best specimens. The book features more than 40 classic American mineral localities, released to commemorate the historic exhibits at the 2008 Tucson Gem & Mineral Show. It contains hundreds of images, historical overviews and insightful commentary. Some collectors have used the book as their “bible”, attempting to collect specimens from all of the superbly documented localities therein. Long out of print and extremely difficult to find today, copies sell for up to $600.00 on Amazon, but you can get it from us for just 150.00 plus shipping! Our new book has one corner slightly dented from shipping but otherwise is in perfect condition!
Minerals of Broken Hill – edited by H.K. Worner and R.W. Mitchell
Another large-format, hardcover work of mineralogical excellence, dealing with the diverse and aesthetic mineralogy of Broken Hill in New South Wales, Australia. The book has 259 pages and 170 full color images with abundant history, paragenesis and descriptions of the complex deposits of this classic locality.

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
This uncommon sulfate-nitrate occurs as minute colorless to white masses and aggregates stored as small chunks and offered here in 2cm stoppered vials. Type locality material, ex-Wards Natural Science from nearly 50 years ago, at just 25.00 per 2cm container.

KALIFERSITE- Rasvumchorr Mt., Khibiny Massif, Russia
Only the second known occurrence for the species, this one also in Khibiny as was the type, kalifersite occurs here as pale yellowish, fine-grained aggregates and druses sparsely filling voids in a dark green aegirine matrix, typically with brownish glassy lamprophyllite etc. Only a few samples available, sizes from about 1.5cm to nearly 3.5cm across @ 45.00, 75.00 and 125.00 each.

KINOSHITALITE- Trumbull Peak, Mariposa Co., California
Described from this locality in 1999, this was the first U.S. occurrence of the mineral, described some 25 years earlier from Japan. Kinoshitalite occurs as tiny, platy aggregates and golden brown flakes sparsely scattered in a sanbornite/gillespite matrix. Only a couple of specimens on hand, sizes average 3cm @ 55.00 each.

LINARITE- Kintore Open Cut, Broken Hill, NSW, Australia
Brilliant micro crystals of darl blue linarite scattered on matrix, these from old materila collected over 40 years ago. Specimens are colorful and will yield good micros as well, sizes from about 2cm to 5cm @ 15.00, 25.00 and 45.00 each.

LUZONITE in BISMUTHINITE etc.- Cerro de Pasco, Pasco Department, Peru
An often-overlooked Cu-As-S mineral, luzonite occurs here as a metallic masses with a slight purplish-red luster, most typically intergrown with metallic masses of tennantite-tetrahedrite, and in this case, bismuthinite. The specimens are ex-J. Cilen Collection, and sizes average about 4cm across @ 45.00 each.

MARIINSKITE (IMA #2011-057)- Mariinskoe, Malyshevskoe, Urals, Russia
This extremely rare species occurs as minute translucent masses sparsely scattered among grains of chromite and phlogopite matrix. Formula: BeCr2O4, orthorhombic, IMA # 2011-057. From the emerald deposits at this famous locality, the mineral is the Cr-dominant analog of chrysoberyl! Only one small (~1mm) microprobed and mounted sample in 2cm probe mount available, accompanied by two SEM backscattered images and a chemical analysis @ 350.00. Type locality specimen from the original discovery; list alternates!

MIMETITE- Aguiles Serdan, Chihuahua, Mexico
From the famous Santa Eulalia Mining District, these are bright yellow drusy crystals of mimetite richly scattered on matrix, occasionally associated with calcite, cerussite or other species. The precise mine is uncertain, as these were acquired in 1957, long before most dealers and collectors cared about such nuances. Colorful, moderately attractive, much micro potential as well, specimens range from about 3cm up to 6cm across @ 8.00, 15.00, and 25.00, with a few monsters to 10cm @ just 50.00 each. Wonderful old stuff from more than 60 years ago!

NISHANBAEVITE (IMA 2019-012)- Arsenatnaya Fumerole, Tolbachik, Russia
This NEW SPECIES forms minute, white crystalline aggregates, mounted on small stubs for microscope viewing. Named for Russian mineralogist Tursun Prnazorovich Nishanbaev (1955-2018) of the Natural History Museum of the Ilmen Natural Reserve, the species formula is KAl2O(AsO4)(SO4) - orthorhombic, IMA # 2019-012. It represents not only a unique combination of elements but also a new structural type. Only a few tiny mounts available @ 145.00 each. Author's material (see our image on Mindat).

OPAL- Antananarivo Province, Madagascar
Very weirdly colored, pale greenish opal comprising matrix, these almost serpentine-like in their opaqueness. Appearing first in early 2009, additional samples have been dribbling out from Madagascar sporadically, with the largest influx in the last two years. Specimens are dense, translucent at best, and quite cutable, and these show very little included matrix. Relatively pure specimens range from about 4cm to 7cm across at just 15.00, 24.00 and 35.00 each.

ORDONEZITE- La Fortuna Mine, Agua Prieta, Sonora, Mexico
This rare mineral occurs as massive brownish to reddish brown pods and veinlets in somewhat cherty to rhyolitic rock matrix, typically with minor chenevixite and possibly other phases. Classic locality in the El Antimonio District, ugly stuff, but not commonly offered, this is very old Cureton stock with specimens ranging from about 2cm to nearly 8cm across @ 15.00, 25.00, 45.00, 60.00 and 75.00 each.

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

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!

RENIERITE- Prince Leopold Mine, Kipushi, Zaire
Germanium sulfide ore material, consisting of chalcopyrite, tennantite, bornite, and renierite intermixed as a rich sulfide ore. Type locality for renierite, distinguishable visually by its slightly more orange tint, sizes from 1cm to 3cm @ just 35.00, 45.00 and 65.00 each.

SUGILITE- Wessels Mine, N. Cape Province, Rep So. Africa
Considerably more colorful than the type Japanese material, this Kalahari material is found as intense magenta colored rock-forming material, with minor matrix, typically with superficial masses well scattered on matrix. Moderately attractive, sizes from 1cm to nearly 5cm across @ 10.00, 15.00, 25.00, 40.00 and 60.00 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- Itaobim, Minas Gerais, Brazil
A beautiful, pale BLUE topaz crystal without matrix! The specimen shows a typical blocky terminated, sharply formed transparent crystal of topaz, ranging in color from almost clear with a hint of blue to pastel blue, naturaly colored, of course, and showing the classic chisel-tip form. The crystal also shows complex modifications along the crystal edges, some damage on the back, and a pinacoidal cleavage at the base. This one is from a 1998 find by the late Luis Menezes. Only one on hand @ 100.00.

URANINITE- Fission Mine, Haliburton Co, Ontario Canada
Dense, crude cubic crystals and masses of blackish uraninite, most without matrix or as partial floaters, these being somewhat brownish on the surface but quite hot! All are relatively pure despite the surface alterations, and all were collected in May, 1981 by Dutch mineral dealer H. Rozenbroek whose collection we recently acquired. Sizes range from smallish (!) 1cm crude crystals up to monster 2.5cm crystalline masses, priced at 35.00, 60.00, 85.00, 110.00 and 150.00 depending on size and degree of crystallization. Wow!

WOLLASTONITE (FL)- Desert View Mine, San Bernadino Co., California
From an unusual locality known for uncommon fluorescent minerals, these wollastonite specimens occur as greenish yellow crystalline masses richly scattered and comprising matrix, all brilliantly fluorescent (yellow-orange LW, less intense SW). Specimens are from the collection of the late NJ Zinc geologist and Franklin master, John L. Baum (johnbaumite). Specimens range in size from about 3cm to 6cm @ 10.00, 20.00 and 35.00 each; one 8cm @ 50.00, and a 10cm @ 65.00. List alternates!

WULFENITE- Hilltop Mine, Cochise Co., Arizona
A neat old specimen, showing many dark, honey-brown tetragonal plates and masses of wulfenite to 1cm perched on heavy, wulfenite-infused limonitic matrix. The specimen is ex-Buckingham, ex-Curt Seegler (seeglerite),accompanied by Seegler's ratty label indicating it was originally from the Streeter Collection, circa 1942. Overall size about 6x4cm @ 65.00 with historic label. One only!

WUPATKIITE- Lenora Gold Mine, Queensland, Australia
An excellent specimen for this rare mineral, here from the Cloncurry District near Mount Isa. The mineral occurs here as pale pink, acicular needle-like crystals forming balls up to 4mm across, and scattered in several areas on a dull, greenish-grey rock matrix. The last wupatkiite we have in stock, overall specimen sizes about 4cm across @ 150.00 and 185.00 each..

YOSHIMURAITE- Taguchi Mine, Aichi Prefecture, Japan
Tiny, lustrous, dark golden-brown cleavages and crude crystals of yoshimuraite sparsely scattered in pink rhodonite matrix, typically with other associated minerals. An uncommon member of the bafertisite group, originally described in the late 1950s. Magnification will be needed, and matrix sizes range from 1cm to 2cm @ 20.00, 30.00, and 45.00 each.

YTTROBETAFITE-(Y)- Yukspor Mt., Khibiny, Kola, Russia
This rare species occurs as minute, pale beige to yellowish brown masses up to a couple of millimeters across, scattered on feldspar and aegirine matrix. All specimens with arrows, XRD and microprobe-confirmed, matrix sizes average about 3cm across @ 60.00 each. Limited availability!

ZIRSILITE-(Ce)- Sagasen, Porsgrunn, Tvedalen, Norway
This uncommon mineral occurs here in rich, pale orange brown masses well-scattered in greyish feldspar matrix, occasionally with other rock-forming minerals. Zirsilite-(Ce) is one of approximately 10 cerium-rich species found here, the pegmatite vein that produced it now under water in this inoperative quarry. Specimens average about 4cm across @ 75.00 each, less expensive and richer than the type material from Tajikistan!

AZURITE with COFFINITE- Sandy Mine, Elk Ridge, San Juan Co., Utah
An odd petrology specimen, ex-Michigan Technological University Collection at the A.E. Seaman Museum (DM 13437), presented here as a large slab-like mass (one face cut) showing numerous medium blue masses of embedded azurite formed from oxidation of chalcopyrite with a dark veinlet purported to be coffinite running through the entire sample, mobilized along a small solution front in sandstone from the Shinarump member of the Chinle Formation. Neither of the species has previously been reported from the locality, collected in 1978 by M, Landress and possibly a localized, unique occurrence! Overall size is 16x13x3 cm @ 65.00.

BARARITE- Burnside, Northumberland Co., Pennsylvania
This uncommon mineral occurs here as greyish white crusts and aggregates, typically intergrown with cryptohalite and pale yellow sulfur. Ugly stuff but quite rare from this unusual locality, offered as small masses in a 2ml stoppered vial @ 15.00; matrix specimens to 1.2cm @ 30.00 each.

BENITOITE with NEPTUNITE- Gem Mine, San Benito Co., California
An exceptional benitoite sample, here as a delightful cabinet specimen that displays four (4) glassy, deep blue benitoite crystals, the largest 1.5cm on edge, associated with a 1x1cm deep red-black terminated neptunite crystal protruding from the bluish crossite matrix, also with mior white natrolite. The benitoite crystals are all brilliantly fluorescent (blue-white under SW UV). The overall specimen size is about 9x6cm, priced at 1800.00. One only of this size and quality!

BERYL var EMERALD w/ PYRITE- Chivor Mine, Boyaca Department, Colombia
A pair of interesting emerald specimens, here as translucent green hexagonal crystals and sections to 1.5cm on matrix, associated with small pyrite crystals typical for the locality.

From an excellent find of several years ago, we acquired a sizeable lot of superb, pale pinkish to white brewsteriteSr specimens, these as richly scattered, blocky pseudomonoclinic crystals, the largest crystals to 5mm, nicely covering Eocene lava rock matrix. These were considered as world class for the species when first offered, and there is only minor Na with trace Ba, K or Ca in these samples, actually richer in Sr than the type locality material! Excellent specimens from TNs to 3.5cm @ just 20.00, 30.00 and 45.00 each, with a few exceptional specimens to nearly 6cm tall @ 75.00, 100.00 and 150.00 each for the finest. Don't miss these!

CALCITE (FL)- Santa Eulalia, Chihuahua, Mexico
Small "spikes" of needle-like calcite spears richly scattered on massive calcite matrix, many showing blue-white fluorescent under SW UV, and an unusual peach colored response under LW UV. A few will even phosphoresce briefly after SW saturation. Old material acquired in 1971, good micro and fluorescent response, very inexpensively priced, sizes from about 2.5cm to 10cm across @ just 4.00, 7.50, 12.50 and 25.00 each. Smaller samples generallyshow better fluorescence, large ones generally more botryoidal in habit.

KOTULSKITE + UNK Pd-Pb-Te-S etc- Federovo-Pansky Massif, Murmansk Oblast, 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 analytical 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.
