CATALOG 21502 – Volume XLII, No. 2

ALUMOAKERMANITE (IMA #2008-049)- Bellerberg, Ettringen, Eifel, Germany
Unusual, pale brownish-tan alumoakermanite crystals well scattered on matrix, these likely from the Caspar Quarry
discovery and collected many years before the species was described and approved. Only two very rich TN-size
samples (about 2.5cm) available @ 85.00 each. List alternates!

ARSENOPYRITE w/ SPHALERITE etc.- San Rafael Mine, Nye Co., Nevada
Excellent, samll diamond-shaped pseudo-orthorhombic crystals of arsenopyrite to 5mm nicely perched in open
seams among black sphalerite crystals and masses, occasionally with minor, needle-like quartz crystals as well,
and often with minor galena and/or pyrite. Rich ore specimens from this fine locality (see our article in Rocks &
Minerals, Vol. 85 (2010), 512-24). Specimen range from TNs up to 6cm display specmens @ just 5.00, 10.00,
20.00 and 45.00 each. Bargains!

ARTINITE- Staten Island, New York City, New York
White tufts and balls of radiating needles of artinite to 1cm scattered on pale green serpentine matrix, occasionally
associated with minor hydromagnesite. These were collected in the late 1960s from the Spring Street housing
project construction site. Specimens range in size from about 3cm to 8cm across @ just 8.50, 15.00, 25.00 and
40.00, occasionally with a few larger ones available - please inquire!

BALANGEROITE- Balangero, Lanzo Valley, Piemonte, Italy
These are easily mistaken for asbestos, forming fairly attractive and rich silky fibrous aggregates and tufts of
balangeroite with minor matrix. A silicate mineral from the type locality, only a few specimens on hand, sizes from
about 2.5cm to 5cm @ 40.00, 65.00 and 95.00 each. Rare stuff!

BARITE nodule- Redhouse Mine, nr. Golconda, Nevada
Weird barite "balls", actually tightly packed and radiating bladed barite forming spherical floater nodules without
matirx, these decidedly ugly and essentially grey in color. From the type locality for curetonite in Humboldt Co.,
these were collected about 25 years ago and appear quite odd, with diameters ranging from about 3cm to 6cm
across @ just 10.00, 20.00 and 30.00 each. Suitable for excellent slingshot projectiles as well!

BARNESITE- Cactus Rat Mine, Grand Co., Utah
This unusual vandium mineral occurs as deep red to red-brown minutely fibrous matted aggregates scattered on
dark sandstone matrix, occasionally with other vanadium species. Matrix sizes range from about 2.5cm to 5cm
across @ 15.00, 25.00 and 40.00 each.

BERTRANDITE w/ FLUORAPATITE- Golconda, Gov. Valadares, M.G., Brazil
Excellent PURPLE apatite crystals to several millimeters long and showing fine vitreous luster are perched in/on
much of the surrounding matrix of these smallish specimens, all with clear to white, somewhat tabular micro
crystals of bertrandite nicely-represented here as well. Ex-Luis Menezes, only a couple of fairly aesthetic
specimens available averaging 2.5-3cm across @ 75.00 each. List alternates!

BERYL- Grafton, Grafton Co., New Hampshire
A large crystallized specimen of pale bluish green beryl, translucent to opaque, showing elongated prism faces of at least two major crystals in parallel growth, all without matrix. Although not terminated, this large specimen (weight about 2.5 pounds!) shows virtually all pure beryl throughout with discernable prism faces around 75% of the surface of this old piece, with the balance a large contact area of one of the major crystals. An old specimen (ex-L.L. Hubbard - born 1849) from a classic New England locality, not especially aesthetic or damage-free, but still a reasonably crystallized monster about 18x8x6cm (!!) at just 175.00.

BERYL variety AQUA/EMERALD- El Toro Pit, Muzo Mine, Boyaca, Colombia
An interesting specimen comprised of numerous pale blue-green, translucent hexagonal beryl crystals free
standing and intergrown together, the largest crystal about 2cm tall and many in the 1cm size range. The locality is well known for marvelous, gemmy green emeralds, but we would call this color closer to aquamarine, much like
Colorado amazonite in hue. There is minor feldspar associated with the piece, but most of the beryls are fully
exposed with sharp, glassy prism faces and occasional basal pinacoid terminations. Overall group size is about
6.5x4.5cm, competatively priced at just 200.00.

CHRYSOCOLLA with TENORITE- Daisy Mine, Hidalgo Co., New Mexico
A colorful boat anchor-size specimen comprised of bright blue-green chrysocolla richly scattered over the surface of a greyish cherty matrix, showing a few small flattened dendrites of arborescent tenorite as well. While this large
specimen could be easily broken down along the chrysocolla seams to offer a large number of pieces, it would no
long keep your boat in place. Size about 15x12cm @ just 65.00. An interesting and old locality piece.

CLINOCHLORE, ALBITE etc.- Nufenen Pass, Canton Tessin, Switzerland
Superb, well crystallized stacked plates of nearly black clinochlore forming fine crystals to 1cm across wellscattered on white albite matrix, assciated with trace, deep red rutile and muscovite. A handsome miniature from a great locality, overall size about 5x4cm @ 125.00. One only!

CRYOBOSTRYXITE (IMA #2014-058)- Tolbachik Volcano, Kamchatka, Russia
This NEW SPECIES, one of several recently approved from this prolific volcano, is offered here as very tiny
colorless single grains hermetically sealed by the authors in glass vials for prevention against dehydration.
Formula: KZnCl3*2H2O - monoclinic, IMA # 2014-058. From the type locality at the First Scoria Cone, only a few
specimens are available @ 145.00 each.

CUMENGEITE- Juliushutte, Astfeld, Harz Mts., Germany
Micro blue crystals of cumengeite nicely scattered in/on grayish ancient slag matrix. A uncommon anhydrous PbCu chloride mineral, rather nice micro material for the locality and a moderately unusual species as well. Ol Cureton stock from many years ago, matrix sizes range from 2cm to 3.5cm @ 17.50, 25.00 and 35.00 each.

CURITE- Shinkolobwe, Shaba Province, Dem Rep Congo
Bright orange masses of curite richly scattered in/on matrix, associated with non-descript yellow masses of other
uranium minerals. Impossible to obtain today, we have only a few small samples on hand from this classic locality.
Mildly hot, small fragments to 1cm @ 30.00 each.

DATOLITE- Dalnegorsk, Primorski Kraj, Russia
A large, pale green datolite crystal pair forming a roughly V-shaped crystal group witjhout matrix, displaying a
pleasingly high luster and sharp faces. Ex-Fersman Museum and J. Cilen collections, overall specimen size is a
fine, 8x4cm specimen @ just 125.00. A bargain!

DIAMOND (1.01 cts)- Birim River, Western Province, Ghana
A wonderfully transparent, pale yellow diamond without matrix, the crystal showing a complex and highly modified
octahedral habit. Surprisingly transparent, the crystal measures 5x4x3mm and weighs 1.01 carats @ just 175.00.
Very fine!

EKANITE- Case Collina Quarry, Pitigliano, Italy
Minute, pale green to brownish green tabular tetragonal crystals of ekanite lightly scattered in vugs of granular
sanidine/quartz matrix. Rarely offered material, many with excellent micro potential, these were collected in 1972!
Specimens average about 2.5 to 3cm @ 30.00 and 40.00 each, depending on quality.

FLUOBORITE- Bodnar Quarry,Hardyston, Sussex Co., New Jersey
Brilliantly fluorescent and crudely crystallized fluoborite highlights these specimens from the Franklin area.
Fluoborite occurs as pale yellow to almost white crystal aggregates to 5mm richly distributed through white marble matrix, FL SW bright creamy-yellow and possibly associated with graphite and non-fluorescent chondrodite. Only a few small specimens from old stock, 2cm to 4cm @ 15.00 to 25.00 each. Old stuff!

FRANCEVILLITE- Mounana Mine, Franceville, Gabon
A small but suberb specimen comprised of rich, greenish yellow micro crystals fully covering the entire top surface
of this excellent, rare specimen. This type-locality piece is ex-University of Arizona, ex-Curtis Schuh, and measures about 3.5 x 3 cm on its fully crystallized surface, only one available, @ 295.00.

GOLD- Unspecified Locality in Virginia
A rather ugly and nondescript specimen of native gold, here as sparse microscopic specks scattered in a corroded
quartz/pyrite matrix. The piece is ex-Philadelphia Academy of Natural Sciences (with their distinctive #7872 painted marking), sadly without a precise location in my new home state. Similar specimens have been found in Orange, Louisa and other counties, but there is insufficient variation among matrix specimens we have seen to pinpoint the locality, as most are in similar assemblages. The first we have been able to offer in some years, overall size about 8.5x4cm @ just 150.00. Quite lean!

LEPIDOCROCITE var. GLOCKERITE- Zuckmantel, Silesia,-now Zlate Hory, Czech R
A facinating specimen, originally labeled by the Michigan College of Mines as "Glockerite - Zuchmantel, Silesia".
The Silesia region is now largely in Poland, but a small portion now sits in Moravia, Czech Republic, as well as in
Germany. The specimen is comprised of dark red-brown shell-like masses, densely intergrown and with minor
traces of flattened, red fibrous aggregates as well as minute dark grey to black masses among this convoluted
specimen. Exceptionally light weight for its size, work on this material in the 1970s suggested that is, in fact, a
variety of lepidocrocite, and the locality (Zlate Hory) is the type locality (1813) for lepidocrocite. This weird specimen measures about 11x8cm and is available at just 85.00. One only!

LIEBENBERGITE- Kamariza, Lavrion, Greece
Minute, transparent, bright green micro crystals of liebenbergite in exposed cavitites, occasionally with Ni-rich
fosterite. Remarkably well-formed, wedge-shaped orthorhombic crystals heretofore unknown, with overall matrix
sizes averaging about 2.5cm across @ 85.00 each, all with good micro potential as well! Only a few specimens
available - list alternates!

LOLLINGITE- Sterling Mine, Ogdensburg, New Jersey
Silvery metallic masses of this uncommon mineral scattered in unusual black(!!) willemite, occasionally with
sphalerite (variety cleiophane) or other species as well. Old material, specimen sizes from 2cm to 5cm across,
priced at just 10.00, 25.00, and 40.00 each.

MAGNESIOPASCOITE- Opera Box Mine, Montrose Co., Colorado
As featured in our recent Mineral News article (February, 2015), these are brilliant, red-orange to brownish orange
micro crystals and crusts well-scattered on vanadium-rich sandstone matrix, potentially with other secondary
vanadium minerals present. Analytically confirmed in our lab (EDS copy supplied), this is a relatively rare member
of the pascoite group, and the first world occurrence reported outside of Utah! Specimens range from about 2cm to 7cm across at just 20.00, 35.00, 55.00 and 85.00 each. Quite colorful for a rare mineral!

MELANARSITE (IMA #2014-048)- Tolbachik Volcano, Kamchatka, Russia
This NEW SPECIES occurs as tiny aaggregates to 3mm of black, lustrous crystals, occasionally with greenish
ericlaxmanite, violet johillerite or black tenorite on basalt scoria. Formula: K3Cu7Fe3+O4(AsO4)4 - monoclinic, IMA # 2014-048. From the type locality at the Arsenatnaya fumarole of the second scoria cone of this famous volcano, only a few specimens available, sizes generally in the 1cm range at 175.00 each. List alternates!

NALDRETTITE- Mesamax NW deposit, Cape Smith, Que Canada
This rare species occurs as minute metallic grains found among Fe-Cu-Ni sulfide concentrates, typically with
chalcopyrite or other phases. Formula: Pd2Sb, IMA #2004-007. Each sample is superbly documented with a pair of SEM images and quantitative chemistry of this relatively new palladium mineral, mounted in a 2.5cm probe mount containing hundreds of concentrate grains, all with multiple naldrettite grains imaged! Only two 2.5cm probe mounts available @ 375.00 each.

NASONITE with GANOMALITE- Crestmore, Riverside Co., California
An old J. Cilen speicmen comprised of massive ganomalite and intergrown on massive grey merwinite matrix, with
two surfaces covered with fluorescent (yellow-SW UV) nasonite well scattered on the surface. An old occurrence,
good fluorescence, size about 3.5x2cm @ 55.00. Moderately rare stuff!

PARAGONITE- Gassetts, Windsor Co., Vermont
This mica group mineral occurs as highly reflective, silvery platy aggregates largely comprising matrix, some with
minor garnet inclusions and possibly other minerals. Rich samples from an uncommon locality, specimens range
from 2.5cm to nearly 5cm across @ 12.50, 20.00 and 30.00 each.

POWELLITE- Black Mountain, Kern Co., California
From a old supply of Wards Natural Science, we have a few specimens of rich, brightly fluorescent powellite largely
comprising matrix. One of the more sought-after fluorescent minerals, these are rather ugly in daylight and would
be easily overlooked, but they are outstanding under SW UV! Specimens range from about 2.5cm to 5cm across @ 15.00, 25.00 and 40.00 each.

PYROMORPHITE- Gute Hoffnung Mine, Bleibuir, Eifel, Germany
Rich, vibrant green pryromorphite as knobby crystallized carpets fully covering the top surface of each of these
matrix specimens. The locality ceased operations in the 1880s, and these are samples likely collected from the
dumps of this old lead-producing locality. Specimens average about 5cm across, quite rich and colorful, at just
35.00 each.

RAISAITE (IMA # 2014-046)- Sentyabr'skoe, Ilmeny, W. Chukota, Russia
This NEW SPECIES occurs here as somewhat rounded, very tiny sky-blue crystal arrgregates up to 0.5mm lightly
scattered in fractures of a slightly oxidized dolomite-calcite-quartz vein with muscovite and rich sulfide
mineralization comprised largely of hessite, altaite, petzite and chalcopyrite from this prolific silver-gold deposit.
Formula: CuMg[Te6+O4(OH)2]*6H2O - monoclinic, IMA # 2014-046. Only a few 2cm specimens available @
185.00 each. List alternates!

RHODONITE- Franklin, Sussex Co., New Jersey
An old specimen comprised of rich, pink rhodonite cleavages, with a number of crude, rhodonite crystals to 2+cm
scattered on top of white calcite and black franklinite ore, with small amounts of brownish andadite garnet and black mica as well. A rather colorful specimen with a number of dings that do not detract from the appearance of the overall ore assemblage specimen. A hefty piece about 10x9cm @ just 125.00, with Franklin Mineral Museum label as well.

SANIDINE- Itrongay Region, Faritra Anosy, Madagascar
Superb, gemmy yellow sanidine without matrix, these as pure, transparent crystalline masses suitable for gem
cutting as well as fine specimens. XRD studies have shown the material to be monoclinic, low-sanidine
composition, not orthoclase as some have previously reported. Specimens are quite pure, all are matrix-free, and
some show modest crystal faces as well, sizes from about 2cm to 2.5cm @ 35.00 and 45.00 each, depending on
quality and size. Excellent!

SHATTUCKITE- Tantara Mine, Shinkolobwe, Dem Rep Congo
Very colorful pale blue, somewhat velvety shattuckite richly and completely comprising matrix, these showing
radiating structure with magnification, and all rather attractive knobs and hillocks of excellent color. There may be
minor admixed plancheite in these, uncovered in the now-abandoned open pit at this famous Katanga locality. Pure specimens, overall sizes from 2.5 to 4cm @ 25.00, 35.00 and 50.00 each, or as larger matrix specimens of calcite and rock with smaller and leaner pods of shattuckite scattered about, averaging 6 to 8cm across @ 55.00 and 75.00 each. List alternates!

SIDERITE var: SHAEROSIDERITE- Clackamas River, Clackamas Co., Oregon
Strange round balls of the siderite variety "sphaerosiderite" to 7mm nicely scattered in exposed vugs in brownish
basalt matrix. A neat curiosity, collected in the 1960s by Ted Morley, specimens from 4cm to 8cm across @ 15.00, 25.00 and 40.00 each.

SVANBERGITE on DOLOMITE- Mt. Brussilof Mine, Radium Hot Sprgs Canada
Certainly the finest North American occurrence of this unusual anhydrous Sr-Al-phosphate-sulfate mineral ever
found, svanbergite occurs here as excellent, orange-brown translucent crystals to 1.5mm richly scattered over
white dolomite crystal groups. Striking contrasts and superb micro material, the trigonal svanbergite crystals appear nearly cubic in habit on these exceptional specimens, avaiable as thumbnails to 2.5cm @ 25.00, 50.00, and 75.00 each, with a few miniature to small cabinet specimens @ 100.00, 150.00 and 200.00. Great stuff - don't miss these excellent, best-of-species samples!

SYLVANITE- Cripple Creek, Teller Co., Colorado
A selection of old sylvanite specimens recently acquired from the University of Arizona, here as brilliant, minute
silvery aggregates of this valuable gold-silver-telluride scattered across massive quartz and on rock matrix. Most
specimens in the lot have modest micro potential, with some of the larger samples potentially showing tiny, discreet elongated crystals as well. Originally Ex-Butler, with a copy of U of A label included, specimens from 2.5cm to 4cm across @ 50.00, 95.00 and 150.00 each. List alternates, please!

ULVOSPINEL- Rother Kopf, Gerolstein, Eifel, Germany
Iron-black, well formed tiny octahedral crystals lightly scattered in vugs in alkali basalt, often with colorless prisms
of nephleine, needles of fluorapatite, greenish black augite, minor leucite and rarely yellowish altered gotzenite.
This is perhaps the first discovery of visible, non-microscopic crystals of microprobe-confirmed ulvospinel!
Specimens average 2cm @ just 125.00 each. Fewer than a dozen available!

ZINCOHOGBOMITE-2N6S- Ismailica Hill, nr Nezilovo, Veles, Macedonia
This uncommon mineral occurs here as yellowish brown to somewhat orange-colored tiny aggregates scattered in
thin veinlets in matrix, comprised largely of quartz, dolomite albite and barite, occasionally with minor gahnite in
metamorphic rock. A rather ugly mineral, and one of those structurally-named species that defies understanding for most (myself included), this is nonetheless type locality material from the Babuna Valley in the Jakupica Mts., and specimens average a about 2.5cm across @ just 65.00 each.

ZIRCON- Mt. Malosa, Zomba, Malawi
Single crystals of medium brown zircon without matrix, most showing good crystal faces on several sides, most
often with a variety of tetragonal forms. Crystals range from about 6mm to 1.2cm, priced individually at 5.00, 10.00 and 15.00 each, or in bulk lots of crystals weighing 50 g or more at just $1.00 per gram.

Marvels of the New West- by W.M. Thayer (circa 1887)
A old bound copy of Thayer's six volume work, described as "A vivid portrayal of the stupendous marvels of the
vast wonderland west of the Missouri River". Illustrated with over 350 engravings and maps, we were especially
interested in the "Marvels of Mining" section of about 100 pages, plus the nature and railroad sections as well. Over 700 pages, hardcover binding loose and worn, contents otherwise in good condition, at just 75.00!
Minerals and Synonyms- by T. Egleston (1892)
This is a complete, unabridged reprint of Egleston's classic work of the 1892 edition of "A Catalogue of Minerals
and Synonyms". The original 379 page work has been faithfully reproduced in a large format (28cm x 21cm)
softcover volume, quite usefully employed for looking up old and obscure mineral names used in the 19th century
mineralogical literature. While our supply lasts: only $15.00 per copy with any mineral order!
SYMPOSIUM on MANGANESE- International Geological Congress Mexico - 1
This extraordinarily rare publication consists of all five volumes (over 1550 pages!) of the 1956 IGC meeting's
Symposium on Manganese, literally covering the world's occurrences, production, and geological make-up of
manganese ores. Numerous maps and diagrams accompany the many articles in these regional monographs by
the leading geologists and mineralogists of the time (I count at least ten with minerals named after them!).
Introductions are in Spanish, the articles in the author's original languange (most in English, some French, Spanish etc.). The five softcover volumes are handsomely boxed and in good condition. The only complete set we've ever seen, one only, @ 125.00 plus shipping.

MYSTERY FLAT- Various Localities Worldwide
They are back: we offer a "mystery flat" of twenty (20) different specimens from worldwide localities, all individually labeled and ranging in size from about 2.5cm to 5cm across for the princely sum of just $125 plus shipping. These are from old collections, excess stock, single specimens and material available only in small quantities too labor intensive to describe and catalog. Some will be colorful, some will be ugly, some will have micro potential, some from obscure localities, but the lot will be worth a minimum of $250 or more, yours sight-unseen for our liquidation price of just $125 plus shipping! Multiple orders up to three sets (60 specimens) received at the same time will not have duplicates! A bargain for anyone wishing to expand their collection horizons! Try one!

Excellent, deep blue sapphire cabochons, all well-polished and showing typical chatoyancy of this vibrantly-colored gemstone. Fine quality and color suitable for jewelry or gem collections, with sizes ranging from about 6x4mm to 9x7mm offered lots of 10 cut stones (about 15 carats) at just 75.00 per lot of 10. Single larger stones in the 12x9mm size range @ 95.00 per stone.

CATALOG 21501 – Volume XLII, No. 1

ALUNITE- Marysvale, Piute Co., Utah
Massive, dull pinkish to tan chunks of alunite comprising matrix, these from an old stock originally supplied by
Ward's Natural Science many years ago. Not particularly attractive, but good representative material of this
anhydrous potassium aluminum sulfate. Specimens range from about 3cm to 6cm across at just 8.00, 15.00 and
25.00 each.

ARSENDESCLOIZITE (CALCIAN)- Illinois Mine, Lodi Dist., Nye Co., Nevada
As described in the upcoming January, 2015 issue of Mineral News, we have verified (EDS and Raman) a find of
calcian arsendescloizite from the first reported occurrence from this old Nevada property. The mineral occurs as
tiny, pale olive green balls isolated on limonitic matrix, typically with micro sheaves of radiating hemimorphite and
occasionally other species. Only a few specimens on hand, each accompanied by copies of our confirming EDS
and Raman spectra, sizes from 2cm to 4cm across @ 30.00, 45.00 and 60.00 each, depending on coverage, most with good micro potential as well.

AZURITE- Chengmenshan Mine, Jiangxi Province, P.R. China
Recently uncovered in the warehouse, a small batch of about a dozen specimens showing platy, radiating and
intergrown azurite crystals completely comprising matrix, some with druses of azurite on massive azurite, all with
excellent deep blue color. These are likely late 1990s to early 2000s vintage, specimens average about 4cm across
at just 25.00 each. A bargain!

BABINGTONITE- Honsarvet, Borlange, Sweden
From our uncovered warehouse stock, we have a small lot of small but fine, sharp black babingtonite crystals to
0.5cm richly scattered in groups in exposed seams in matrix, associated with minor pale green epidote, drusy
quartz and possibly other species. Quite good for the species from an unusual locality, these from a single pocket
found prior to 1996. Overall specimen sizes from 4cm to 7cm @ just 15.00, 25.00 and 45.00 each. Neat!

BAYLDONITE- Black Pine Mine, Granite Co., Montana
From our study material used for the June, 2012 Mineral News article on the locality, we have a few select
specimens of olive green to bright green bayldonite from this prolific mine, here as somewhat flattened,
rhombohedral micro crystals and aggregates on matrix, most associated with other secondary minerals and all
making rather attractive samples with good micro potential. Matrix sizes range from about 2.5cm to 4.5cm @ 15.00, 25.00 and 45.00 each!

BIGCREEKITE- Esquire #7, Big Creek, Fresno Co., California
This rare mineral occurs as colorless to white striated aggregates sparsely scattered in exposed fracture fillings in
quartz-sanbornite matrix. Formula: BaSi2O5.4H2O - orthorhombic. From the original 1980 find by one of the
authors, the mineral was IMA-approved in 1999. All specimens with arrows, overall sizes are TNs to 2.5cm @
75.00 each. Only a few available!

BORNITE etc.- Bawana Mine, nr. Milford, Beaver Co. Utah
This is rarely offered primary copper mineralization from the well-known Bawana (Old Hickory) Mine, famous as the type localities for the copper silicate minerals stringhamite and whelanite. The bornite is dark bluish black, dense and with little or no matrix, although polished sections have shown intergrowths of other copper sulfides such as covellite and djurleite. Specimens take an excellent polish, overall sizes ranging from about 2.5cm to 6cm across @ 5.00, 10.00, 20.00, and 40.00 each. Rich and heavy!

BROCHANTITE etc.- Lost Soldier Mine, Lyon Co., Nevada
Dark green micro brochantite crystals are scattered over rock matrix, some associated with minor, deep blue
linarite and occasionally transparent druses of anglesite. An uncommon locality. only a few specimens on hand,
ranging in size from about 2.5cm to 4cm @ 7.50 and 15.00 each; one larger 7x4cm specimen @ 35.00. List

CAMEROLAITE- Spania Dolina-Piesky, Slovak Republic
Pale blue minutely fibrous masses and aggregates of this rare complex copper mineral scattered on rock matrix.
From the second locality for the species, these vary from lean to very rich, sizes about 2cm to 5cm @ 50.00, 75.00, 100.00, 150.00 and 200.00.

CHRYSOTILE- Phillipsburg, Warren Co., New Jersey
A large, glass test tube approximately 15cm long and 3cm in diameter, cork stoppered and filled with a white,
elongated masses of solid but fibrous chrysotile. The old collection label (circa 1951) indicates associated
sillimanite, but we suspect tremolite as a more likely companion mineral. An uncommon locality specimen, Ex-H.E. Moore collection, one only, @ 30.00 with its old and very cool packaging method.

DAVYNE in SANIDINE- Mt. Cavalluccio, Sacrofano, Latium, Italy
From a relatively recent analytical discovery, this uncommon cancrinite-group mineral occurs here as micro, short
prismatic glassy hexagonal crystals scattered in sanidine ejecta, occasionally with black hornblende and possibly
other minerals. All specimens with one or more arrows, with over 25 different species known to occur here, matrix
sizes from about 2cm to 3cm @ 45.00 and 55.00 each.

DIAMOND- Vaal River, Northern Cape Province, Rep So Africa
An excellent, complexly intergrown octahedral group of transparent, white diamond crystals without matrix, the
sample appearing much like a small bunch of octahedral grapes with well-formed faces evident from all angles. The
group weighs about 2.88 carats and measures 10x7x6mm, offered at just 625.00. One only!

EMPRESSITE- Tombstone, Cochise Co., Arizona
Representative samples of this silver telluride occurring as gray metallic masses in quartz-rich matrix. Empressite
may be associated with primary pyrite and a host of secondary tellurium minerals in these samples, possibly
including rodalquilarite and other rarities. Sizes from 0.5cm to 2cm @ 10.00, 15.00, 25.00, and 40.00 each.

EPIDOTE in QUARTZ (Coll 1903)- Isle Royal Mine, Houghton Co., Michigan
A wonderfully historic specimen, collected in August, 1903 by a young Scott Turner (b. 1880), one day to become the Director of the Bureau of Mines in the Hoover administration. The specimen is a cut and polished basaltic nodule that shows fine green epidote scattered in rims around quartz/rock matrix, along with very tiny, sparse flecks of apparent native copper seen under magnification. The locality now sits under several Houghton stores and is long-gone. Turner's very ratty, handwritten label accompanies the specimen, overall size about 9x6cm @ 55.00. One only!

Old classic specimens comprised of densely packed rhodonite & schefferite/hausmannite skarn matrix, with small
areas of dark reddish black platy aggregates of ericssonite, with intergrown orthoericssonite as well. The later has
been relegated to polytype status, formally named ericssonite-2O, while ericssonite is the 2M polytpe, now all
considered a single phase within the ericssonite group. Only a few available, sizes in the 2cm to 3.5cm range @
35.00, 55.00 and 125.00 each for the richest. Type locality, of course!

FAIRFIELDITE- Foote Mine, Kings Mountain, North Carolina
Buff colored radiating aggregates and balls of fairfieldite nicely scattered over pegmatite matrix. The locality has
produced nearly 150 different species, and this is old material, excellent for both the locality as well as this
interesting phosphate species. Matrix sizes from 2.5cm to 6cm across @ 20.00, 35.00 and 50.00 each, many with micro potential as well.

FERROMERRILLITE- Los Angeles, L.A. County, California
This exceptionally RARE SPECIES occurs here as minute aggregates in the 1999 find of the Los Angeles
meteorite, a rare Martian basaltic shergottite! Only two small LA meteorite samples were discovered, and
subsequent study of the Shergotty meteorite and this material has led to the IMA-approval (#2006-039) of this
rare phosphate mineral. Formula: Ca9NaFe(PO4)7; author's studied material, ONLY ONE individual grain available
in a 5mm probe mount @ 450.00, accompanied by superbly documented full quantitative chemistry and SEM
image as well. List alternates all you phosphate, systematic and California collectors; this specimen will sell out

GRAPHITE- Lime Crest Quarry, nr. Sparta, New Jersey
Thick, steely grey greasy mass of platy graphite perched in calcite matrix, typically with several other minor graphite flakes as well. From old material collected by H.E. Moore on May 18, 1969 at the quarry! Moderately rich
specimens about 2.5cm to 3.5cm @ 10.00 and 15.00 each; one larger piece about 6x6cm @ 35.00. List alternates!

GYPSUM variety SELENITE- La Union, Sierra de Cartagena, Spain
From an old hoard of Hamel Mining & Minerals, we have uncovered a small lot of excellent, relatively large and
well-terminated single crystals of gypsum from this excellent European locality. Similar to fine "Cave of Swords"
specimens, these show good transparency with sharp prism faces and pointed terminations, sizes ranging from
8cm to 15cm tall @ 30.00, 50.00 and 75.00 each. Nice!

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

KASOLITE, SODDYITE, URANINITE- Shinkolobwe Mine, Katanga, Dem Rep Congo
An old David New specimen comprised of very rich, yellow soddyite well-scattered over black uraninite/sulfide
matrix, with small masses of orange kasolite and potentially many other species scattered about in micro
aggregates. The locality has produced nearly 125 different minerals and 34 type specimens, many new
radioactives described in the last 25 years that postdate this rich, 1970s specimen. We note a number of
unidentified phases on this hot specimen (~4000 cpm), overall size about 4.5x3cm @ 175.00. List alternates!

KEUTSCHITE (IMA #2014-038)- Uchucchacua Mine, Oyon Province, Peru
This NEW SPECIES is offered here as tiny metallic masses of type material, mounted on adhesive carbon tape in a
transparent micro box. Formula: Cu2AgAsS4, tetragonal, IMS # 2014-038, a new member of the stannite group.
These are each accompanied by a signed F. Keutsch label and are from the type material used in the description of
the species. Only a few 0.5mm samples available at 150.00 each. List alternates!

KOLICITE- Sterling Mine, Ogdensburg, Sussex Co New Jersey
The last of our stock of this rare mineral: tiny individual tabular crystals and aggregates of orange-brown kolicite,
named for the late John Kolic, miner extraordinaire at Sterling Hill. Only a few specimens available, either as tiny
(<1mm) tabular crystals in a vial without matrix @ 55.00 each, similar samples on 3mm matrix @ 95.00. List

KYANITE & TOURMALINE QUARTZITE- Chocolate Mts., Imperial Co., California
These are roughly slabbed specimens of massive kyanite in quartzite, most with small masses of black tourmaline
lightly scattered in the rich, pale blue kyanite matrix. Old material uncovered in a large lot of cutting rough, these
display reasonably well and might yield several good cabochons if so inclined. Slabs range from about 5cm to
11cm across and 1.5 to 3cm thick, weights in the 75g to 500g+ range @ 10.00, 20.00, 30.00 and 45.00 each.

MALACHITE etc.- Orogrande District, Otero Co., New Mexico
Excellent green fibrous bowties and sprays of micro malachite well scattered on limonitic matrix, many with black
tenorite, tiny botryoids of chrysocolla and possibly other phases. Colorful miniatures that have fine micro potential
as well, specimens average about 5cm across at just 7.50 each! A bargain find of old material!

MARIINSKITE (IMA #2011-057)- Mariinskoye, Malysheva, Urals, Russia
This relatively NEW 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 (and only!) locality; list alternates!

MICROCLINE with MUSCOVITE - Narrows Water Tunnel, Goethals Bridge, New York
Platy pink-hued microcline covers one surface of this pegmatitic specimen that shows a number of 1cm muscovite
books scattered in quartz/feldspar matrix, plus a couple of small fluorescent (orange-SW UV) unknown pods as
well. The piece was collected on October 26, 1970 from beneath the Narrows Water Tunnel on the Staten Island
(NY) side of the Goethals Bridge that connects Staten Island, New York with Elizabeth New Jersey. Great locality
piece but not much to look at, size about 9x4cm with H.E. Moore Collection label @ 25.00.

NEPTUNITE- Mina Numero Uno, San Benito Co., California
Nearly black micro crystals of neptunite to several millimeters richly scattered on bluish crossite matrix, with overall sizes ranging from 5cm to nearly 10cm across @ 35.00, 55.00 and 85.00 each. Larger, well formed crystals from the Gem Mine, typically on white natrolite over blue crossite matrix, matrix sizes from 5cm to 8cm @ 100.00 and 150.00 each, priced according to quality.

PASCOITE etc.- Burro Mine, San Miguel Co. Colorado
From one of the more prolific areas for unusual vanadium-rich species, we have a few older specimens collected by
E.W. Heinrich and others from this great locality, some specimens associated with pale yellow-green metarossite
and possibly other rare phases. Specimens vary in size from about 3cm to nearly 8cm across, priced according to
richness and size @ 15.00, 30.00, 45.00 and 75.00 each.

PATRONITE- Minas Ragra, nr. Cerro de Pasco, Peru
Rather nondescript, greyish black masses of this uncommon mineral densely scattered and cementing vanadiumrich ore matrix. Type locality material from several old collections, specimens ranging in size from about 1.5cm to 7cm across @ 15.00, 45.00 and 85.00 each,

PHENACITE with BERYL- Mt. Antero, Chaffee Co., Colorado
A rather large and vaguely unattractive matrix specimen showing a couple of glassy white phenacites (largest is
1.5cm long!!) perched in a subtle depression in quartz-rich granitic rock, also showing several thin, pale blue beryl (aquamarine) crystals to 7mm in the same 5cm depression on the surface of this hefty rock matrix. While the piece begs to be trimmed to potentially uncover more goodies, we offer this older specimen un-worked. If the TV show "Prospectors" is to be believed, this is a $2500 rock, but reality suggests this 14x7x7cm monster is more appropriately priced at a modest 200.00, first come, first served!

QUARTZ - Duaphine Twin Law- Viesch Glacier, Switzerland
An old L.L. Hubbard (b. 1849) specimen displaying a largely water-clear, slightly curved quartz crystal showing
"trapeziohedral-tetartohedral" faces with a distinct twin boundary at the top of the crystal. The front, top and one
side of the crystal is complex and undamaged, the rear and bottom show attachment points, plus a conchoidal
fracture area on the left edge of the crystal. Ex-A.E. Seaman Mineral Museum sample with old cardboard label, the
locality is unique, crystal size 5x3.5cm @ 85.00. One only.

QUARTZ variety AMETHYST- Piedra Parada, Tatatila, Veracruz, Mexico
An old stash from the defunct stock of Hamel Mining & Minerals, these are pale amethyst crystals in singles and
small groups, all nicely terminated with color more at the terminations than along the prisms, some showing
various degrees of scepter-like habit. Perhaps the finest Mexican quartz occurrence (formerly noted as Las Vigas)
due to the clarity and quality of the crystals and delicate color, specimens available as singles or interesting groups from 2cm to 5cm @ 15.00, 25.00, 40.00, 55.00 and 75.00 each. Attractive!

RHODOCHROSITE- Silverton, San Juan Co., Colorado
Colorful small groups of pink, rhombic rhodochrosite crystals well scattered on drusy quartz-covered matrix,
occasionally overlaying thin seams of various sulfides. Old specimens largely from the G.F. Lincks collection, some
mounted on styrofoam as was the custom in the 1960s, these range from neat little TNs to 5cm specimens @
25.00, 45.00 and 75.00 each. Difficult to obtain today!

RUTILE- Agua Calgada, Fraguita, Atacama, Chile
From a unique and bizarre alpine cleft in the normally barren Atacama Desert region of Chile, these highly unusual
rutiles occur as thickly aggregated, elongated and flattened red crystal sections and sagenitic forms richly scattered in matrix. Quite colorful from this extraordinary geological oddity for the region, uncovered about 15 years ago, matrix sizes from about 2.5cm to 5cm across @ 15.00, 25.00 and 45.00 each.

SERPIERITE with WILLEMITE etc- Sterling Hill, Ogdensburg, Sussex Co New Jer
After checking a number of pale blue secondary minerals found on "red willemite ore" from Sterling Hill, we are
finally able to offer verified samples of serpierite from this famous locality. The mineral occurs as quite sparse, pale
blue to blue-green aggregates and flakes lightly scattered on red willemite matrix, typically with franklinite,
occasionally minor kraisslite, sarkinite etc. X-ray data indicates monoclinic symmetry, eliminating orthoserpierite.
Specimens range from about 3cm to nearly 6cm @ 15.00, 30.00 and 45.00 each, depending on coverage and size, each with a copy of our EDS spectra.

TETRAHEDRITE- Black Pine Mine, Granite Co., Montana
From another lot of studied specimens, we have several TN-sized samples of tetrahedrite in vugs and seams with
quartz, most typically small but relatively sharp and often associated with pyrite, platy huebnerite and occasionally
arsenian pyromorphite or other species. Matrix sizes average about 2.5cm at just 6.00, many with micro potential
as well.

ULEXITE- Boron, Kern Co., California
Excellent, polished cross sections of nature's "fiber optic" rock! The ends of these fibrous sections have been lightly buffed so that light and images are transmitted through the material when placed over a written page, for example. Great for demonstrating the concepts of fiber optics, specimens from about 3x2cm to 8x4cm @ 7.50, 12.50 and 20.00 each. Neat!

URANINITE- Frey Point, Red Canyon, San Juan Co. Utah
A rich, dense specimen comprised of massive black uraninite admixed with metallic bornite comprising matrix, likely from a rich vein section within deep channels in the Shinarump formation with no apparent country rock present. The specimen is surprisingly hot, running about 6000 cpm! The locality includes many prospects and workings in the Frey Point area in the early 1950s, with over 300 tons of uranium/copper ore extracted prior to 1950, and others that warranted drilling to a depth of 9000 feet. A very hot locality piece, size about 5.5x4cm @ just 195.00.

VIKINGITE- Apache Hills, Hidalgo Co., New Mexico
This rare mineral occurs here as small metallic aggregates scattered in rock matrix, originally supplied by Dr.
Sidney Williams from his X-rayed and microprobed material, typically admixed with other sulfides. Only a few rich
specimens on hand, sizes averaging about 1cm @ 55.00 each.

WULFENITE etc.- San Rafael Mine, Nye Co., Nevada
Transparent, colorless to slightly greyish tabular platelets of micro wulfenite scattered on matrix, some associated
with tiny hexagonal mimetite crystals, and possibly green bayldonite, jarosite, etc. well scattered and with good
micro potential. The locality has produced over 65 valid species, and one is referred to our 2010 article in Rocks &
Minerals (V. 85, pgs 512-524) on the mine for other possible associations. An uncommon color for wulfenite,
specimens range from about 2.5cm to 4cm across @ 15.00, 25.00, and 45.00 each. One 9x8cm piece @ 95.00.

NEW MINERALS (1995-1999)- by J.A. Mandarino
A superb abstracting of all new mineral species published during the period of 1995-1999 in a very readable format. Over 280 pages of precise scientific, locality and useful collector data in a softcover volume, tightly bound with most copies lightly scuffed on the binding, but graced with an excellent color cover photo of the type specimen of andyrobertsite! A number of crystal drawings and several useful tables are also provided in this 24x17cm volume @ just 25.00. The last of this very useful and informative series that Joe Mandarino edited until his untimely demise in 2007, devoting one page per species, much like the heralded Handbook of Mineralogy. Limit one per order.

CHESTER EMERY MINE- Chester, Hampden Co., Massachusetts
Recently uncovered in our warehouse, a collection of 16 specimens from the collection of the late G. Fred Lincks,
these all from the Chester Emery Mine and likely used a reference collection for the locality. In addition to various
emery samples, we noted margarite, corundophyllite, diaspore, tourmaline, talc, magnetite and others, all with
attached tags and some still Styrofoam mounted as was the rage back in the 1960s. Offered as a lot, specimen
sizes from about 4cm to 8cm across @ just 99.00 for all. Over 40 different species have been reported from this
old, eastern U.S. locality! Only one collection available!

The latest rage in jewelry, these are facetted black diamonds, typical size about 3.5mm across and in a round
princess cut. We assume virtually all modern gemstones are treated in some manner, and these should be
considered likewise. Interesting additions to your diamond or gemstone collections, these are just 40.00 each, or
75.00 for a matched pair.
CABOCHON COLLECTION- Various Localities Worldwide
 A recent collection purchase included a large number of cabochons, most calibrated in sizes ranging from
14x10mm up to 40x30mm in a wide variety of materials including tigereye, various agates, sodalite, rhodonite and
many more. We've seen some of the larger ones retailing for 15.00 or more each, but this is not our niche and
would like to move these quickly. To that end, we offer a large assortment of cabs, a total of 60 pieces in all sizes
that retail in excess of 350.00 for just 99.00 per lot! Great for jewelry makers and collectors alike. What a deal!

CATALOG 21409 – Volume XLI, No. 9

ANGLESITE etc.- Black Pine Mine, Granite Co., Montana
Translucent to frosty white micro spears of anglesite scattered in highly vuggy quartz matrix, invariably associated
with numerous other micro species such as oxyplumboromeite, mimetite, brochantite, malachite, beudantite etc., a few of the better ones lightly colored pale blue due to linarite inclusions. Only a small number of samples available,all suitable for good micromounts, matrix sizes from about 2cm to 5cm across @ 10.00, 20.00 and 35.00 each.

ARSENOPYRITE- Gold Hill, Tooele Co., Utah
Better known for its wide range of colorful secondary minerals, Gold Hill once had the largest reserves of arsenic
mineralization in the U.S.. Arsenopyrite was a rich, As-producing primary ore, and it is more rarely seen in many
Gold Hill collections because of the emphasis on the attractive secondary copper and/or arsenate minerals. We
have a small selection of very rich, solid arsenopyrite, forming nearly pure, silvery grey masses, with overall sizes
ranging from about 3.5cm to 6cm across @ just 10.00, 15.00 and 20.00 each. Own a piece of the primary ore to
supplement your Gold Hill secondary minerals collection!

ASHBURTONITE- Anticline Deposit, Ashburton Downs, Australia
Minute blue crystalline aggregates of ashburtonite sparsely scattered on matrix, most associated with somewhat
paler caledonite and possibly other minerals. This relatively rare mineral is available as small, 0.5cm to 2cm matrix
specimens @ 45.00, 60.00 and 85.00 each, one 5cm specimen @ 150.00.

ASTROPHYLLITE- Mont Saint-Hilaire, Quebec, Canada
This interesting MSH mineral occurs here as golden brown to dark brown needle-like crystals and fattened
elongated laths on matrix, primarily as micro material collected over 30 years ago. Small TN samples in the 1-
1.5cm size range, all quite nice under the'scope, at just 12.50 each.

AXINITE-(Mg)- nr. Luning, Mineral Co., Nevada
From one of the few confirmed localities for the species, the mineral occurs here as clove-brown, glassy crystals
and partial shards, all showing at least several good crystal faces and typically without much matrix. The crystals
range from about 1cm to nearly 2.5cm tall, all from a lot purchased many years ago from the late A.L. McGuinness (of mcguinnessite fame), all moderately attractive and reasonably priced at just 15.00, 25.00 and 40.00 each, depending on quality and size.

BERYL - Mt Tom, Moodus, Middlesex Co., Connecticut
A rather large yellow beryl perched on and protruding nicely from white feldspar matrix, the beryl crystal measuring about 10cm x 1.5cm (!!) and shows good prism faces but no pinacoid terminations. The beryl (dare we call it heliodor?) is translucent to opaque but richly hued, and we strongly believe the piece was repaired at sometime in the distant past. The locality is now in a State Park and closed to collecting. An old Thurston's label is included, overall size about 11x10cm and offered as a repaired specimen @ just 75.00. One only!

CHALCOPYRITE on BARITE- Dreislar Mine, N. Rhine-Westphalia, Germany
Old material obtained in the 1970s, comprised of white to slightly pinkish-tan, platy barite comprising matrix,
liberally sprinkled with small metallic chalcopyrite crystals. The locality was worked as early as the 1870s and is
now defunct, specimens range from about 4cm to 10cm across, offered at just 10.00, 25.00 and 45.00 each, a
great buy!

CHLORARGYRITE- San Rafael Mine, Nye Co., Nevada
From our 2010 article on this prolific locality in Rocks & Minerals magazine, we offer an excellent, hand-picked
selection of chlorargyrite specimens! Nearly end-member in composition, this AgCl mineral occurs as waxy greygreen to slightly yellowish tiny micro crystals and aggregates nicely scattered in spongy matrix, often associated with unusual micro wulfenite and/ or mimetite, as well as other potential species. Specimens range in size from about 2.5cm up to 7cm across @ just 10.00, 25.00, 40.00 and 65.00 each. Good stuff!

COPPER- Keeweenaw Peninsula, Michigan Recently uncovered in old Russ Buckingham material, an exceptional copper specimen from Michigan's Upper Peninsula, here as a complexly crystallized specimen about 28 cm long (!!!) comprised of rounded crystals, crude spinel twins, and massive copper! Looking like a wildly conceived sculpture, the piece shows very minor interstitial white rock matrix and a sparsely scattered, green secondary copper patina at one end of the sample. This long and convoluted specimen is 28cm long (almost a foot!) and weighs about 650 g (over 22 ounces for the metricchallenged), one only @ 650.00 net plus shipping.

DIAMOND - BALLAS CRYSTALS- Namaqualand, Northern Cape Prov., Rep So Africa
Perhaps the strangest of all diamonds following the bemusing carbonado stones of the Central African Republic
and Brazil, the ballas crystals of Namaqualand are steely grey, almost hematite-like black in luster and color, and
they form curious single rounded balls. Many of these are being cut and are finding their way into the jewelry trade
as faceted black diamonds at prices far above their value! We have a rather extensive selection of rough crystal
sizes, ranging from about 4mm (1.4ct) @ 40.00, to progressively larger ones @ 55.00, 70.00, and 80.00 each for the largest ~6mm (2.7ct) ones. More fun than playing with peas.

DIOPSIDE- Yates Mine, Otter Lake, Quebec, Canada
A large specimen comprised of numerous, dark green diopside crystals perched on matrix and largely comprising
the entire specimen, with elongated crystals to 1.5cm, many singly terminated, densely scattered throughout. A
rather attractive clinopyroxene specimen, generously sized at about 11cm across, at just 55.00.

DIOPSIDE variety MALACOLITE- Russell, St. Lawrence Co., New York
A rather unusual pair of intergrown, partial diopside crystals forming a 60 degree "X" pattern, both opaque, pale tan in color, and with no other appreciable matrix. This "malacolite" variety shows good parting along (001), and both crystals show well-defined prism faces with single terminations. The specimen is accompanied by its NY State Museum Institute (Academy of Mineralogy) label, as well as a RMS label from our acquisition some 15 years ago. Overall specimen size is about 4.5 x 3cm @ just 50.00; an excellent miniature from an old New York locality.

EPIDOTE with QUARTZ- Centennial #2 Mine, nr. Calumet, Michigan
Old material comprised of excellent, deep green, tiny epidote crystals richly scattered in large exposed seams in
rock matrix, most with excellent micro quartz crystals and occasionally with minor white datolite. The Centennial #2 shaft (one of seven at the mine) produced these superb pieces some years ago, and now the dumps are gone.
Moderately attractive hand specimens with good micro potential as well, sizes from 5cm to monster 12cm samples @ just 15.00, 30.00 and 55.00 each.

FERRIMOLYBDITE- Glen Innes, New South Wales, Australia
Bright yellow, micro radiating tufts of ferrimolybdite richly scattered in seams and vugs of hard quartz matrix,
possibly with other phases. Excellent locality material with an added bonus of good micro potential. Old material,
specimen sizes from about 2.5cm to 7cm across @ just 15.00, 25.00, 45.00 and 65.00 each. Nice!

Small, dark red-brown to nearly black cubic crystals and aggregates of this pyrochlore group mineral richly
scattered in carbonatite matrix, some associated with perovskite, strontian calcite etc.. A prolific and welldocumented locality for this rich niobium phase, matrix sizes from 2cm to 6cm across with a few tiny crystals
therein @ only 15.00, 30.00 and 45.00 each.

HETEROSITE- White Elephant Mine, Custer Co., South Dakota
This iron-manganese phosphate occurs as satin-like, purplish to magenta masses very richly scattered on matrix,
occasionally with triphylite as well. These are colorful specimens often mislabeled as purpurite, sizes from 3cm to
7cm, quite reasonably priced, @ 10.00, 17.50, 25.00 and 40.00 each.

KUTNOHORITE- Kutna Hora, Bohemia, Czech Republic
Pearly masses of white to pale pinkish tan kutnohorite scattered in matrix, some associated with minor sulfides and possibly other admixed carbonates. Type locality material from an old Czech collection, matrix sizes from about 1.5cm to 3cm @ 15.00, 25.00, and 40.00 each.

LEPIDOLITE- Himalaya Mine, San Diego Co., California
From an old crate recently opened in our warehouse, a rich selection of pinkish-lavender colored lepidolite well
scattered in matrix, here as tightly intergrown, small hexagonal platelets nicely covering a quartz/albite matrix.
Better than the usual mine run material these frequently show some decent crystallization, specimen sizes ranging
from about 3.5cm up to 8cm @ just 5.00, 10.00, 20.00 and 35.00 each.

MALACHITE with CERRUSITE- Brown's Prospect, nr.Darwin, N.T. Australia
Colorful samples collected in the early 1970's have velvet green malachite overlaying matrix, all with white to
frosted cerussite crystal aggregates scattered over the malachite, some mixed with micro yellow botryoidal
mimetites. Stunning contrasts in texture and color make these reasonably attractive vintage pieces for this locality. Sizes range from about 3.5cm to 6cm across @ 30.00, 45.00. and 60.00 each, priced according to quality.

MUSCOVITE crystals! - Hiddenite, Alexander Co., North Carolina
Excellent micro crystals of elongated, columnar, hexagonal muscovite well scattered 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 with fine micro potential as well, ranging from
about 2cm to 3cm across at just 5.00 each and 7.50 each!

NIOBOKUPLETSKITE- Mont Saint-Hilaire, Quebec, Canada
From a small lot collected in 1981 and previously identified as astrophyllite nearly 20 years before the
niobokupletskite was described as a species, this uncomon mineral occurs in these samples as densely fibrous,
yellow-brown mats and hairs richly intergrown on matrix, often with white feldpar and/or dark aegirine. Only a few
specimens on hand, most probably as overgrowths over underlying kupletskite, all with excellent micro potential,
sizes from about 1cm to 1.5cm @ 30.00 and 45.00 each. List alternates!

PERHAMITE- Tom's (PO4) Quarry, Kapunda, S.A., Australia
White micro crystals of perhamite sparsely scattered on matrix with minor crandallite and possibly other
phosphates. Lean but representative for the species, matrix sizes average about 2.5cm to 3cm @ 30.00 and 40.00; a few to nearly 7cm across @ 75.00 each.

PHLOGOPITE- Maria Mine, nr. Milford, Beaver Co., Utah
From a modest selection of brilliant green, translucent to transparent phlogpite without matrix, these recently
featured and pictured in the November, 2014 issue of Mineral News. The mica shows excellent color zoned bands
of several shades of green and brown when thin sections are back-lit, and our analytical work (copy supplied)
points to a slightly ferroan composition. Quite attractive for the species, collected over 25 years ago, tabular
specimens from 4cm to 10cm across @ just 5.00, 10.00 and 20.00 each.

PYROLUSITE- Black Metals Mine, Lincoln Co., Nevada
From material collected over 20 years ago, these are rich specimens of elongated, needle-like radiating laths to
5mm densely intergrown in matrix, with good coverage, some as stouter, coarsely crystalline material. The latter
habit is similar to what was once called "polianite", now relegated to varietal status typically suggesting pyrolusite
psuedomorphs after manganite. From a closed locality, specimens range from about 3.5cm to 8cm across @ just
5.00, 10.00, 20.00 and a couple at 30.00 each.

QUARTZ- Vizilla, Isere, Rhone-Alpes, France
Neat quartz specimens from the eastern edge of the country in the French Alps, all singly terminated and in
pleasing thumbnail groups in the 2-3cm size range, some with brownish siderite balls. Inexpensive specimens
offered at just 7.50 each, with a few larger (but uglier) hand specimens to 6cm @ just 20.00 each. A steal for the

SODALITE variety HACKMANITE- Mont St. Hilaire, Quebec, Canada
This is interesting fluorescent primary material for a locality more known for its rare secondary minerals. We have
the hackmanite variety of sodalite, pale blue to whitish grey in room light, but brightly fluorescent orange under LW, duller and more subdued red under SW. Non-fluorescent associates include aegirine and possibly other species. Old material collected in the 1970s during field trips by Julius Weber, sizes ranging from 3cm to 12cm across at just 7.50, 12.50, 20.00, 35.00 and 55.00 each.

A MONSTER specimen, ex-U.S. National Museum and with their label, acquired in the distant past when
exchanges with the Smithsonian were still feasible. The piece is a large display specimen that shows numerous
isolated sphalerite crystals of deep root-beer brown color to 2cm on edge, highly lustrous, and scattered over
golden brown, bubbly druses of siderite which completely cover the underlying rock matrix. The piece also shows
pale purple fluorite cubes to 1.5cm nicely scattered about the specimen, and they are superbly fluorescent under
both SW and LW UV as well, adding to its presentation value. The underside of this large, trianglar specimen also
shows larger, nearly white crude fluorite with smaller but more richly scattered sphalerites, fully covering this
exposed seam. The sample measures an astounding 32 x 23 x 7 cm, offered at just 750.00 from this classic
locality. Excellent provenance, and quite heavy, too!

STILBITE-Ca- Snake Hill, Secaucus, Hudson Co., New Jersey
Small beige colored stilbite-Ca crystals and sheaves richly scattered over dark, metasediment matrix, some
occasionally with minor fluorapophyllite and possibly other species. These were collected in August, 1972 and have just recently come to light in our warehouse. The "hill" itself was quarried from the late 1800s forward, and has been largely removed for roadway rock and is no longer extant. Specimens range from 8cm to 14cm long, thin to thick with varying widths and all fully covered with small crystals on one surface at just 20.00, 25.00 and 30.00 ea.

STOLZITE- Sumidouro de Mariana Mine, M. G., Brazil
Vitreous, bright yellowish orange micro crystals and aggregates of this uncommon mineral well-scattered on quartz matrix, most with micro potential and all easily visible due to their striking orange color!

For micromounters, sand collectors and the curious, we stumbled upon a small E.W. Heinrich-labeled jar containing heavy mineral concentrates from the dredge jigs at Cascade, Idaho. In his classic book (Mineralogy and Geology of Radioactive Raw Materials - 1958), Heinrich notes that the placers at Cascade contain monazite, zircon (FL orange), garnet, ilmenite (most prolific), magnetite, apatite, columbite-tantalite and other species. We've packaged about 40 grams of this granular concentrate into a 5.5x4cm clear display case, including a copy of Heinrich's label, for just 15.00 per case. Historically and mineralogically interesting and sure to provide fun under the scope!

HYDROCARBON variety SHUNGITE- Shunga, nr. Lake Onega, Karelia, Russia
A concerted effort to bring more of this unusual hydrocarbon to market has resulted in a modest discovery with a commensurate oversupply from this well known palaeoproterozoic deposit. The material, nearly 98wt % pure carbon, has been cleaned by tumbling, resulting in lightly polished, nearly black submetallic stones about 2cm across at just 10.00 each! The least costly we have ever had - don't miss these!


A number of our regular email clients have been lost over the years as their email addresses change when they move. We must then resort to a more costly paper mailing like this catalog. Postage rates will be going up again in January. If you have an email address, we would much rather send you our lists via email, rather than by the slower and more expensive snail mail. Sooo……

SEND US YOUR EMAIL ADDRESS! WE DO NOT SHARE THIS INFORMATION, and it would be used exclusively for getting our regular lists to you more quickly!

The mineral occurs as 1mm-3mm yelllowish to white pearly scales in a sodalite-natrolite matrix. Far superior to the tiny amount of material we secured some years ago, these range from 1.5cm to nearly 4.5cm across at 65.00, 95.00, and 125.00 each, or a few capsules available @ 55.00 each.

SIDERITE/GOETHITE ps COPROLITE- Mahajanga Region, Madagascar
For those really strange curiosity collectors out there, we have obtained a small load (no pun intended) of 40 million year old crocodile droppings, replaced by a mixture of siderite and goethite but retaining their unique and unmistakable form. Thankfully solid and odorless, these average about 6cm long @ just 15.00 each.

SPESSARTINE in MUSCOVITE- Wiseman Mine, Mitchell Co., North Carolina
Glassy red, flattened spessartine garnet frozen in thin sections of silvery, translucent muscovite. The garnets are typically small and their restrained growth as flattened pods makes them of special interest, and we have a few specimens ranging in size from about 6cm to 10cm across @ 25.00 and 45.00 each.

SPURRITE (lavender!)- South Sister's Peak, Luna Co., New Mexico
Pale lavender colored massive spurrite largely comprising matrix. Specimens show occasional white, somewhat chalky spots of merwinite (?), and the spurrite is noted for its unusual, non-polysynthetic twinning on (205) observed in thin section. When in combination with the more common (001) polysynthetic twinning, cyclic twins are observed. Old Ward's material, specimen sizes average about 5cm across @ just 20.00 each.

TETRAHEDRITE (Argentian)- Kellogg, Shoshone Co., Idaho
Rich greyish metallic masses of silver-rich tetrahedrite scattered in pale brown siderite matrix. Our analytical confirmation shows approximately 9.4 wt% Ag substituting for copper, but this is insufficent to be categorized as freibergite, the silver-dominant species also known from the district. Specimens are old Ward's material, sizes averaging 2.5cm to 4.5cm @ just 10.00, 17.50 and 25.00 each, with a copy of our analytical work.

TREMOLITE (Fluorescent)- Franklin Quarry, Franklin, Sussex Co New Jersey
Collected sometime in the early 1970s, tremolite occurs here as small, white bladed aggregates lightly scattered in matrix. The tremolite is best distingusihed by its brightly fluorescent (blue-white under SW UV) nature. Only a few available, matrix sizes from about 3cm to 6cm across @ just 10.00 and 20.00 each.

"TURGITE" over KYANITE- Graves Mountain, Lincoln Co., Georgia
Weird specimens, collected in the 1960s by Ted Morely of Piedmont Minerals, all showing densely aggregated plates of intergrown kyanite blades that are consistently and completely coated by iridescent brown "turgite", an ill-defined mixture of hematite and goethite. The iridescent colors are mostly blues, greens and purple shades, and they add an unreal appearance to these otherwise complex specimens. We located a total of nine large specimens in our warehouse, sizes ranging from about 6cm to 10cm across @ just 20.00, 35.00 and 55.00 each. Old-time stuff, and larger ones are fairly heavy!

TYUYAMUNITE- Jo Dandy Mine, Montrose Co., Colorado
Despite their visual simialrite to the carnotites from the same locality (see earlier in this list), the lack of associated gypsum, different underlying matrix and slightly more greenish yellow color prompted analytcal checking that confirmed these as tyuyamunite rather than carnotite. Specimens show rich coverage of micro aggregates, sizes from 2.5cm to 5cm at just 8.50, 15.00 and 25.00 each; a few larger to 8+CM @ 50.00, all with a copy of our confirming analysis.

WILLEMITE- Franklin, Sussex Co., New Jersey
We've sorted through hundreds of pounds of willemite and selected a handful of choice, greyish white to pale willemite specimens that show superb, brilliant green fluorescence under SW UV, all in nicely isolated, thick bands in ore. One of the more desirable willemite habits in good hand specimens in franklinite ore. Old stuff, choice hand specimens in the 6cm to 10cm size range at just 35.00 and 55.00 each.

Type locality material, all specimens with arrows, specimens from about 2.5cm to 4.5cm across @ 55.00, 80.00 and 120.00, depending on quality and crystallization.

COPPER- Bridgewater Mine, Somerset Co., New Jersey
Old specimens from this long-defunct locality that was reopened about 1820 and was sporadically worked until 1910. The native copper occurs here as thin seams and masses running through rock matrix, some with drusy calcite and occasionally unconfirmed secondary copper phases usually labeled as "chrysocolla". Rather ugly stuff that might clean up respectably, specimens are all from the Howard E. Moore collection and were collected between 1934 and 1939. Sizes range from about 6cm to 12cm across, priced at just 45.00, 65.00 and 95.00 each.

DIAMOND (FLUORESCENT!)- Bloomfontein, Orange Free State, Rep So Africa
Small but brilliant, gemmy, pale yellow diamond crystals without matrix from this prolific locality, here selected from several thousand loose crystals because of their unique blue fluorescence under LW (and lesser SW) ultraviolet light! In our experience, less than 10% of all diamonds will show any fluorescent response, and these have the bonus of being gem quality octahedrons as well! Sizes average about 2mm @ just 25.00 each! The only available "native element" that fluoresces!

ENARGITE with CALCITE- Butte, Silver Bow Co., Montana
An old, A.E. Seaman Mineral Museum specimen and accompanied by their label, the sample shows densely crystallized metallic enargite richly comprising matrix, with numerous small rounded crystals of white calcite liberally scattered over the surface. A small adhered label is also attached to the bottom of the piece, overall size about 8x7cm @ 150.00.

FAHEYITE- Sapucaia Mine, Galileia, M.G., Brazil
The first of this rare and complex Be-Fe phosphate species we have offered in some time, these are small micro groups of white fibrous needles perched on tiny matrix pieces of muscovite, smaller samples placed in capsules or larger ones mounted in a plastic micro box. Overall sizes average 2mm priced according to quality and coverage @ 50.00 and 65.00 each. Limit one per order, please!

FLUOR-LIDDICOATITE- Antandrokomby, Antananarivo, Madagascar

Formula: Ca(Li2Al)Al6(Si6O18)(BO3)3(OH)3F - trigonal. Not particularly attractive, but representative material, sizes from about 1.7cm to 5cm across, the larger sizes showing some striated faces, @ just 20.00, 45.00 and 75.00 each.

FLUORLAMPROPHYLLITE (2013-102)- Morro do Serrote, Pocos de Caldas, Brazil
Another NEW SPECIES from Minas Gerais, fluorlamprophyllite occurs as yellowish brown elongated micro aggregates scattered in nepheline syenite matrix, typically with nearly black aegirine, microcline, natrolite etc. Formula: Na3(SrNa)Ti3(Si2O7)2O2F2-monoclinic, IMA #2013-102. A new member of the lamprophyllite group, specimens from 2cm to 4cm @ 45.00, 65.00 and 95.00 each. Type locality material, of course!

FLUORO-LEAKEITE- Norra Karr, Jonkoping, Smalland, Sweden
This complex amphibole, approved in 2009, occurs here as dark greenish blue, thin flattened and elongated crystalline aggregates lightly scattered in matrix. The list of amphiboles continues to grow as a result of better analytical tools and restudy of old specimens from classic localities, and these thin samples range from about 1.5cm to 4cm long @ 20.00, 40.00 and 60.00 each. Type locality material, only a few on hand!

HYDROCARBON variety GILSONITE- Bonanza Vein, Bonanza, Uintah Co., Utah
If you are lacking black ugly hydrocarbons in your collection, have we got a deal for you! Variously named as "mineral pitch", kerogen, bitumen, asphaltum, uintahite or other obscure designations, gilsonite is one of four hydrocarbon minerals found in the Uintah Basin, and it is described more fully in a recent (Vol 30, No.4) Mineral News article by geologist Bob Werner, The material is black with a glassy luster, fairly brittle and shows good conchoidal fracture patterns, much like that seen in obsidian. Specimens are pure, relatively light and range in size from about 3cm to 6cm across @ just 5.00, 10.00 and a few at 15.00 each, depending in overall size.

HYDROKENOELSMOREITE- Germania Mine, Stevens Co., Washington
From one of the three co-type localities, this newly defined species (2010) occurs here as yellowish brown filmy crusts sparsely scattered on vuggy quartz matrix, collected sometime in the 1970s and originally named as ferritungstite, since relegated to a Fe-rich variety of this hydrous Fe-W oxide. Only a few specimens on hand, sizes from about 2cm to 4cm across @ 25.00, 40.00 and 55.00 each.

JOANNEUMITE (IMA# 2012-001)_- Pabellion de Pica, Chanabaya, Chile

Formula: Cu(C3N3O3H2)2(NH3)2 - triclinic, IMA #2012-001, Type locality material, some with modest micro potential, and all specimens with arrows, sizes from 2.5cm to 5cm across @ 55.00, 75.00 and 100.00 each. Only a few available!

KONONOVITE (IMA# 2013-116)- Arsenatnaya fumerole, Tolbachik, Russia
Yet another NEW SPECIEWS from this famous Kamchatka volcano, these from the second scoria cone of the northern breakthrough of the Great Tolbachik Fissure Eruption. The new mineral occurs as white prismatic to thickly tabular submicro crystals (0.1mm) that form visible white crusts over the volcanic scoria. Formula: NaMg(SO4)F - monoclinic, IMA #2013-116. Named for Russian mineralogist Oleg Vasil'evich Kononov (b. 1932), specimens average about 5mm across @ 125.00 each. List alternates!

LANGITE- Black Pine Mine, Granite Co., Montana
From our studied material published in the June, 2012 issue of Mineral News, we have a few specimens of langite, rarely found at this prolific locality! The mineral occurs as electric blue, transparent micro crystals in vugs, typically with pale mimetite needles, beudantite and a variety of other species. Excellent micro's, choice specimens from about 1.5cm to 5cm across at 15.00, 25.00, 40.00 and 60.00 each. Limited!

LEGRANDITE- Mapimi, Durango, Mexico
Not the type locality for this zinc arsenate mineral, but perhaps the best known, legrandite occurs as small, well developed yellow transparent microcrystals and crude, translucent radiating crystalline aggregates to in vuggy limonitic gossan matrix. Representative and moderately attractive, with micro potential on some to boot. Sizes from about 2cm to 6cm across priced to quality and size @ 15.00, 30.00, 45.00 and 65.00 each.

LENGENBACHITE- Lengenbach Q., Binnetal, Valais, Switzerland
Type locality material! Lengenbachite occurs as small platy to foliated grey metallic masses in aggregates and in vugs in sugary dolomite, often associated with similar appearing but somewhat granular jordanite. Typical material from this prolific locality obtained from a Swiss museum, in sizes from 2cm to 6cm @ 45.00,
65.00, 95.00 and 125.00 each.

LITHIOWODGINITE w/ TA-WODGINITE- Tanco Mine, Bernic Lake, Manitoba, Canada
This relatively rare species occurs as small brownish masses sparsely scattered in quartz matrix. Originally obtained in the early 1990s from the authors when proposed as tantalowodginite, [formula: (Mn,Li)4(Ta,Sn)4(Ta,Nb)8O32 - monoclinic], they subsequently withdrew it when redefining the wodginite group in 1992, instead determining that it is perhaps a mixture of two phases, lithiowodginite and Ta-rich wodginite. It was further studied for a number of years and erroneously published in Canadian Mineralogist (Vol. 39, pg 917-023) as approved tantalowodginite after it was resubmitted in 2000 (IMA #2000-026). The material formerly called tantalowodginite, and the 2000-026 mineral, are still either "discredited" or "suspended", respectively, in IMA parlance. Tired of waiting, we have decided to release the material held in stock for so many years based on the published 1992 reference calling it lithiowodginite+Ta-rich wodginite. Only a few specimens on hand, primarily matrix samples to 1cm with a tiny dark brown mass on each @ 50.00 per sample. Someday, it may be redefined again...

MALACHITE- Lottery Mine, White Pine Co., Nevada
From an obscure locality, these are small green tufts of malachite scattered on limonitic, somewhat vesicular matrix, some of the larger specimens with small pods of white, globular "cave calcite". The Lottery Mine name appears in the local tax records, but nowhere else! Specimens show moderately good color contrasts and range from about 2.5cm to 10cm across @ just 7.50, 15.00, 25.00 and 35.00 each.

NARSARSUKITE- Sage Creek, Whitlash, Liberty Co., Montana
Perhaps the least known of the several narsarsukite localities, this Montana occurrence consists of mustard yellow crystalline masses in quartz and/or grayish green aegirine. Moderately rich, nice specimens, 3cm to 7cm @ 30.00, 45.00 and 65.00 each.

NICKELTSUMCORITE (2013-117)- Km-3 Mine, Lavrion, Attiki Pref., Greece
Another NEW SPECIES from the well-known Lavrion (Laurium) district, here as brown to yellowish brown crusts and tiny (<1mm) aggregates overgrowing an assemblage of calcite, dolomite, annabergite, gaspeite etc., occasionally with Mn-oxides or Sb-rich phases of the romeite group in Ni-Pb-As-Sb ore veins. Formula: Pb(NiFe3+)2(AsO4)2(H2O,OH)2 - monoclinic, IMA # 2013-017. Type locality material and the Ni-analogue of tsumcorite, all with arrows from 1.5cm to 2.5cm @ 125.00 and 155.00 each, depending on coverage.

NIOCALITE- Oka, Quebec, Canada
This unusual species, a calcian niobian silicate, occurs as mm-sized prismatic crystals scattered through matrix. Besides the brownish yellow niocalite, the matrix may also contain dark grey crystalline latrappite and possibly other phases from this classic locality. Sizes from 2cm to nearly 8cm @ 15.00, 30.00, 45.00 and 75.00 each.

NORSETHITE- Kremikovtsy, nr. Sofia, Bulgaria

ATACAMITE- Kadina, South Australia, Australia
Small green aggregates lightly scattered over pale brown rock matrix, these from material obtained in the late 1970s. Not as rich as other Australian localities specimens, these range from about 3cm to 6cm across @ 15.00, 25.00 and 40.00 each, some with modest micro potential.

BOULANGERITE- Oberlahr, Westerwald, Rhein-Pfalz, Germany
Old Ward's Natural Science specimens comprised of dense, massive, silvery-grey boulangerite matrix, potentially with other admixed metallic Pb-Sb-S phases. A somewhat flattened, fibrous structure can be seen under magnification, and this Rheinland-Palatinate material may be from the Silberwiese Mine, although not labeled as such on the original Ward's labels. Specimens range from about 2.5cm to 4cm across @ 15.00 and 25.00 each. Old and difficult locality material to obtain today!

BOURNONITE in QUARTZ- Horhausen, Altenkirchen, Rhineland, Germany
A recently uncovered lot of old material, ex-Wards, but precise vintage unknown despite the inclusion of "Nassau" in the locality labels (Nassau borders have changed many times and ranged from a single town to a large area later part of Prussia!). The bournonite occurs as greyish black, metallic masses richly scattered in white quartz matrix, most specimens showing minor green secondary copper mineral alterations, white cerussite, and possibly other phases. Presented here as chunks of fairly rich ore, specimens range from about 2.5cm to 3.5cm @ just 10.00 and 15.00 each from this classic Dana locality!

BROCHANTITE- Black Pine Mine, Granite Co., Montana
Tiny bladed micro crystals of dark green brochantite scattered on matrix, some with massive azurite, chrysocolla and possibly other species. An interesting assemblage with modest micromount potential, matrix sizes from 2cm to 3.5cm @ 8.50, 12.50 and 20.00 each; a few to 5cm @ 35.00. Uncommon at the locality!.

CELESTINE (Orange!)- Caledon Township, Ontario, Canada
Recently uncovered after our warehouse move, we stumbled upon a box of orange (!!) celestite obtained in the mid/late-1970s. The celestine forms flattened, deep orange crystalline aggregates to several centimeters across (larger in larger specimens) richly scattered in greyish limestone matrix. The locality is likely the Deforest Quarry, but these were was simply noted as Caledon Township. A paper in American Mineralogist (Vol. 64, pgs 160-8) opined that the color was caused by 50ppm inclusions of copper, of which several primary and secondary minerals are known from this locality. Interesting material, and a rare color for celestine, specimen sizes range from about 3.5cm up to 9cm across @ just 10.00, 20.00, 30.00 and 45.00.

CERUSSITE- Mammoth-St. Anthony Mine, Tiger, Arizona
Old-time classics from this famous Pinal County locality! These cerussites form nicely reticulated groups of free-standing translucent crystals and aggregates with or without matrix, all showing moderately well-formed crystals up to a centimeter or more! From an old hoard, likely from the Collins Vein, these range from about 2cm to 3.5cm @ only 15.00, 25.00 and 45.00 each. Very nice for old time stuff!

COPPER pseudo @ ARAGONITE- Corocoro, La Paz Department, Bolivia
Wonderful pseudohexagonal aragonite-shaped crystals completely replaced by copper, retaining their original, sharp habit. Recently described in Mineral News (May, 2014) we have a number of these exceptional, classic locality pseudos, sizes in singles and intergrown groups from 1cm to nearly 1.8cm @ 20.00, 30.00 and 45.00 each.

DELINDEITE- Mt. Rasvumchorr, Khibiny, Kola, Russia
From an unusual occurrence, we recently acquired three small specimens of micro, pale yellow, lamellar delindeite scattered in an orthoclase-rich pegmatite matrix, here associated with dark bronze-colored astrophyylite and occasionally with fibrous pale brown lorenzenite as well. Interesting association pieces with modest micro potential from an unusual locality, specimens average 2.5-3cm @ 125.00 each. List alternates!

DELVAUXITE var: BORICKITE- Brandberg, Leoben, Styria, Austria
This strange mineral, alternately known as foucherite, then borickite (aka borickyite), and now considered to be delvauxite (itself ill-defined), occurs here as orange-brown crusty masses scattered on hard rock matrix. Very old material from this excellent locality, variously labelled as Tollinggraben or simply Leoben, either as small samples in a capsule @ 10.00, or as larger matrix specimens from 1.5cm to 3cm @ 25.00 and 40.00 each; one rich, large ,ex-Albanese specimen, 6cm @ 75.00.

DEPMEIERITE- Karnasurt Mine, Lovozero, Kola, Russia
This relatively rare species occurs as colorless aggregates, offered here as small, relatively pure masses. Found underground by mine geologists in association with minor natrolite in a hyperagpaitic hydrothermal vein more than 25 years ago, and only in a single specimen (!!), this new cancrinite-group mineral was subsequently approved about 5 years ago. Formula: Na8[Al6Si6O24](PO4,CO3)1-x*3H2O - hexagonal, the PO4-dominant analog of cancrinite, vishnevite, hydroxycancrinite and kyanoxalite. IMA #2009-075, named for German crystallographer W.H. Depmeier (b.1944), only a few small samples on hand averaging 0.5cm across @ 125.00 each. A rare, one-locality species! List alternates!

DESAUTELSITE- Union Carbide Mine, San Benito, California
Orange, minutely platy aggregates of desautelsite thinly encrust areas of a serpentine matrix. Some samples have minor white fibrous tufts of artinite, and each comes with a photocopy of a locality label signed by the late Paul Desautels. Sizes are 2.5cm to nearly 6cm @ 15.00, 25.00, and 40.00 each; a few showy samples, slightly larger @ 65.00 each.

DIAMOND- Northern Cape Province, Rep So Africa
A very strange group of four intergrown and somewhat rounded transparent to translucent diamonds without matrix, these forming an odd "L"-shaped crystal group with numerous, highly modified crystal faces! Weight is 4.82 carats, measuring about 1cm along each "leg". A nicely visible, intergrown group that is relatively inexpensive @ just 650.00 for this unique diamond specimen!

DOLEROPHANITE- Tolbachik Volcano, Kamchatka, Russia
This rare copper mineral occurs as minute brown to black micro crusty aggregates and well-formed, complex doubly terminated micro crystals scattered on scoria matrix, often associated with other obscure bluish green copper phases and commonly with green euchlorine. Only a few samples available, far superior to earlier material from 10 years ago, sizes ranging from about 0.7cm to 3.5cm @ 45.00 for small micros, the larger matrix samples @ 75.00, 100.00 and 150.00 each.

ENARGITE with QUARTZ- Moonlight Mine, Butte, Silver Bow Co Montana
Another old-timer from one of the many Butte sub-localities, here as nodular crystals of enargite scattered across the top of the specimen, with stout, milky white quartz points protruding through the enargite. Provided to Michigan Tech by A.M. Mackenzie in the distant past, a pyrite and sulfide rich matrix underlays it all, overall size about 8x7cm @ 135.00, with old cardboard label.

GALENA- Galena, Cherokee Co., Kansas
A beast of a specimen, comprised of densely intergrown galena cubes from 1cm to 2.5cm across in a heavy, upright specimen. The galena crystals comprise most of the piece, and there is a minor amount of rock matrix across the back of the specimen. A white alteration (anglesite?) on the back of the piece coats smaller
crystals, while the front and sides have a sporadic, brownish overgrowth in the recesses of the sample. A large, old specimen (once belonging to English-born John Gerry a mine captain in the Michigan iron mines) that could use some cleaning, it weighs about 7 pounds and measures a hefty 13x10x9cm @ 250.00. Heavy!

GLAUCOCHROITE- Franklin, Sussex County, New Jersey
Typical multi-mineral ore samples taken from the Joe Cilen collection and elsehwere, gluaocochroite occurs as a grey, non-fluorescent, association with brilliantly fluorescent willemite and franklinite, and possibly with fluoresecent clinohedrite or hardystonite (no calcite!). Older, quality pieces, three on hand at 3cm to 5cm @ 80.00, 90.00, and 100.00 each, depending on coverage.

GLAUKOSPHAERITE- Carr Boyd Nickel Mine, W. A., Australia
A copper-nickel member of the rosasite group, glaukosphaerite occurs as medium green crusts on matrix, possible occuring and admixed with takovite and other secondary nickel minerals. Good coverage for this mineral, in sizes from 2cm to 7cm across @ 15.00, 25.00, 45.00, 60.00 and 75.00 each.

GOLD- Mile End, New South Wales, Australia
An older specimen from this obscure locality, here showing about a half-dozen micros of crystallized gold scattered on a slightly ferruginous quartz and rock matrix. Although the sample could be trimmed to produce a handful of fine micromounts, we appreciate it more as a small hand specimen. The collection vintage is sometime in the early 1970s, overall size about 4.5x4cm @ 150.00.

HOLMQUISTITE- Uto, Sodermanland, Sweden
A lithium rich member of the amphibole group, holmquistite occurs as dark bluish black fine grained elongated masses comprising much of this amphibolite rock, occasional prismatic crystals or silky masses of the mineral are evident as well. Excellent type locality material, sizes from 2cm to nearly 5cm @ 20.00, 35.00, and 55.00 each. One 8cm sample, ex-E.W. Heinrich, @ 65.00.

JOHNBAUMITE- Franklin, Sussex Co., New Jersey
Spotty masses of grey to pale greenish grey aggregates of johnbaumite scattered in matrix, these associated with brownish andradite garnet and brilliantly fluorescent willemite, occasionally with other possible species. The johnbaumite is mildly fluorescent as well (SW orange), and this material came from a single boulder collected at the former Franklin Mill Site in October, 1983 by yours truly. Recent analytical work confirms the material as AsO4>PO4 with little or no fluorine, confirming what many believe that the mineral may be more common at Franklin than previously thought. Specimens range in size from about 3cm to 6cm across @ 15.00, 25.00 and 40.00 each.

KEGELITE- Tsumeb, Namibia
This rare mineral occurs as pearly white aggregates well scattered and comprising the upper surface of these small matrix specimens. One of the more difficult to obtain Tsumeb species, ex-Walter Kahn material obtained many years ago and suitable for good micromounts. Priced according to coverage and size, with specimens ranging from 1mm to 6mm across @ 25.00, 40.00, 60.00, 85.00. Rare!

KYANITE in Pegmatite- Windham, Cumberland Co., Maine
Three large specimens, quite old and originally collected by L.L. Hubbard (1849-1933) that subsequently found their way to the A.E. Seaman Mineral Museum before landing in our warehouse some years ago. The specimens show richly scattered, thick, pale blue blades of kyanite from 5cm to 10cm long well-scattered in quartz-dominant matrix. Exceptionally rich specimens that will clean up to excellent cabinet pieces from this old locality. Overall specimens sizes range from 13x10cm up to 21x11cm (!!), priced at just 60.00, 85.00 and 100.00 each. Heavy!!

METARAUCHITE- Belorechenskoe Deposit, N. Caucasus, Russia
This rare mineral occurs as minute, yellow crystalline druses scattered on matrix. Described in 2008 in the Czech Republic (IMA 2008-050, formula: Ni(UO2)2(AsO4)2*8H2O), the mineral remains difficult to locate and has been confirmed from fewer than five localities worldwide. The Belorechenskoe deposit (type locality
for rauchite) was the subject of an excellent, detailed article in the Mineralogical Almanac (Vol. 15, Part 2) and is known for both its nickel and uranium minerals that occur there. We have only a few confirmed specimens, sizes average 2.5-3cm across and are priced at 150.00 each.

MOUNTKEITHITE- Mount Keith Deposit, W.A., Australia
Sparse pale pink masses of mountkeithite are scattered over a bleached serpentinite rock. Derived from the alteration of deeper pink to purple associated stichtite, other associated species include magnetite and possible hexahydrite. A rare, one-locality mineral, each larger sized matrix piece has one or more areas of the mineral. Sizes from 2.5cm to 7cm across @ 45.00, 65.00 and 95.00 each.

NABIMUSAITE w/ YE'ELEMITE- Jabel Harmun, Judea Desert, W.Bank, Israel
This NEW SPECIES occurs within the Palestinian Autonomy and is a co-type sample, offered here as a 1cm polished section in a 2cm probe mount. Formula: KCa12(SiO4)4(SO4)2O2F - trigonal, IMA # 2012-057. The mineral occurs as microscopic colorless grains with ye'elemite, associated with larnite and minor brownmillerite matrix, accompanied by complete chemical quantification as well as three SEM images that pinpoint the various species in the sample. Only one available, superb documentation, at 350.00.

NELENITE- Huanggang Mine, Chifeng, Inner Mongolia China
From a relatively recent find, this rare mineral occurs here as micro hexagonal plates that are typically stacked in minute, somewhat globular aggregates nicely perched on white, rhombic cleavages of calcite matrix. Identification has been confirmed by chemistry, XRD and Raman, and a copy of the original Raman spectra is included with each sample. Coverage is obvious to the naked eye and will also yield decent micromounts if trimmed further. Specimens range in size from about 1 cm up to 4+cm @ just 15.00, 30.00 and 55.00 each.

PARATACAMITE-(Mg) IMA #2013-014- Quebrada, Camarones, Chile
This NEW SPECIES occurs as glassy green, micro crystals sparsely scattered over rock matrix, occasionally with other rare copper phases. Formula: Cu3(Mg,Cu)Cl2(OH)6 - trigonal; IMA #2013-014. This is author's material and a new member of the atacamite group. Specimens will yiled modest micros upon trimming, and
overall sizes average about 3cm across at 120.00 each. List alternates!

PHLOGOPITE w/ PARGASITE - Limberg Quarry, Pargas, Finland
A very old specimen, accompanied by a heavily aged Helsinki Mineral Museum label obtained years ago during one of our trips to Finland. The specimen shows a fairly large, columnar phlogopite crystal about 4cm tall and 2cm wide, perched at the edge of a massive, etched white calcite matrix, accompanied by greyish-green grains and globular aggregates to 1.5cm of analytically-confirmed pargasite. Only one specimen available, a classic from this famous locality, overall size about 10x6x6 cm @ 250.00.

POLLUCITE- Tanco Mine, Bernic Lake, Manitoba, Canada
Nearly pure, greyish white massive pollucite comprising matrix, occasionally with minor quartz. X-Ray verified material, sizes from 2cm to 5cm across @ 8.00, 15.00, 25.00, and 45.00 each, a few to 8cm to 12cm @ 65.00, 85.00 and 100.00, from one of the better documented localities for the species!

PSEUDOMALACHITE- Inspiration Consolidated Copper Mine Arizona
A large specimen, ex- A.E. Seaman Mineral Museum, comprised of hefty rock matrix with pale blue-green chrysocolla and other pale green secondary copper staining, with approximately two dozen, dark greenish-black, wonderfully spherical and isolated pseudomalachite balls scattered about on one surface, most in the 2-3mm size range. They contrast nicely against the pale blue-green undercoating, and the piece might be from the Thornton Pit, although the museum label does not specify it, instead indicating the 1912 name of the consolidated workings of this prolific copper ore property in the Globe-Miami District of Gila County. Overall size is about 12x8x5cm at just 125.00.

QUARTZ- Grymes Hill, Staten Island, New York
An odd assortment of matrix specimens showing small cloudy grey to slightly greenish quartz crystals well-covering a limonitic mass. Some samples show a transparent layer over a included quartz, while others are rather opaque, tan-green color. These were primarily collected in 1961 by H.E. Moore, and these odd, New York City specimens are from 4cm to 7cm @ just 15.00, 25.00 and 40.00 each; one 10cm specimen @ 65.00. From a great locality near Wagner College that now overlooks the Verrazano-Narrows Bridge!

QUARTZ (Smoky)- Anderson's Gully, Mooralla, Victoria Australia
Excellent, doubly terminated small groups of fine, dark brown smoky quartz crystals without matrix. These show multiple crystal faces. some with apparent reverse scepters and other odd habits, all with good luster and richly colored transparency as well. Specimens range from about 2.5cm to 3.5cm @ 15.00 and 25.00 each. Great locality stuff that is attractive and weird as well!

SCHUETTEITE- Oceanic Mine, San Luis Obispo Co., California
Canary-yellow, earthy masses of this rare secondary mercury mineral intergrown in brick-red cinnabar/clay matrix, possibly with other, non-descript secondary mercury minerals. Old, type locality material, only a few specimens available, sizes from 2cm to 5.5cm @ 15.00, 25.00, 45.00 and 60.00 each.

SCOLECITE w/ FLUORAPOPHYLLITE- Pune District, Maharashtra, India
An attractive group of richly intergrown, slender, transparent to opaque white scolecite (EDS confirmed), with some crystals somewhat flattened and surrounding a few pale green fluorapophyllite crystals peeking out among the scolecites. This moderately attractive piece measures about 12x9cm @ is just 65.00.

SEPIOLITE- Valley Quarry, Valley, Stevens Co., Washington
Rich, white, fibrous sepiolite largely comprising matrix, occasionally with minor dolomitic marble present among the seams. The material was collected circa 1980 and is the only reported occurrence of sepiolite in the state of Washington (see Mineral News, May, 2006), although the locality was largely unknown and
is not documented in MinDat or any of the regularly available references to minerals of Washington. While similar palygorskite has been reported in the State, our EDS (and earlier XRD work) confirms the absence of necessary aluminum found in palaygorskite. Perhaps a unique occurrence, now closed, these uncommon, fibrous specimens range in size from about 4cm to 12cm long @ just 7.50, 15.00, 25.00 and 40.00 each for the largest.

SIDERITE with NATIVE COPPER- Ray, Pinal Co., Arizona
Weird, murky green siderite balls and dumbbell-shaped sheaves a few millimeters across, lightly scattered on quartz/rock matrix, all with small but excellent arborescent masses and/or spinel twinned spears of native copper, some piercing the siderite or showing a variety of forms on the same specimen. Old material acquired over 30 years ago, these are unusual specimens likely confined to a single occurrence, and not found in the usual Arizona literature from this defunct locality. Specimens range in size from about 2cm to 4cm across @ just 7.50, 12.50 and 20.00 each, most suitable for micros as well!

SPENCERITE- Hudson Bay Mine, Salmo, B.C. Canada
Pure white, somewhat micaceous and pearly platy aggregates of spencerite without matrix. A rare zinc phosphate from the type locality, originally obtained from the Royal Ontario Museum. These are offered as small fragments in a capsule @ 15.00; matrix specimens from 0.8cm to nearly 4cm @ 25.00, 50.00, 100.00 and 200.00 each.

STICHTITE- Stichtite Hill, Dundas, Tasmania
Rich, deep lilac-purple masses of stichtite generously scattered throughout matrix, most with minor green serpentine in association. Very colorful, classic material, matrix sizes from 2.5cm to 6cm @ 12.50, 20.00, 30.00 and 45.00 each. A few to 12cm across and quite attractive @ 75.00!

Formula: Cu3MgCl2(OH)6 - trigonal, IMA # 2103-077. Excellent, colorful druses with modest micro potential for a new species, sizes average 2.5-3cm @ 125.00 each. Only a few available!

TOPAZ (Imperial)- Ouro Preto, Minas Gerais, Brazil
Excellent single crystals of imperial color topaz without matrix. These are singly terminated with good prism faces and display fine pinkish sherry to mild honey color throughout. Gemmy and attractive, getting considerably more difficult to acquire economically, these are older samples from about 1cm to nearly 2.5cm @ just 10.00, 20.00, 30.00, 45.00 and 60.00 each, depending on size and color.

VESUVIANITE variety CYPRINE- Parker Shaft, Franklin, Sussex Co., New Jersey
A hefty hand specimen of rich, pale brown andradite showing excellent patches of blue vesuvianite (variety cyprine) scattered throughout the piece. There is much willemite in the specimen, but it is only evident under SW UV, as is a generous but filmy patch of clinohedrite (FL SW orange) on one edge of the specimen. Minor calcite, and possibly other phases, are present as well. Ex-H.E. Moore Collection, overall size about 6x5cm @ 65.00.

ZADOVITE (IMA #2013-031)- nr. Arad, Negev Desert, Israel
This NEW SPECIES, a co-type sample from the paralava of the Hatrium formation at the Gurim anticline, occurs as colorless, submicroscopic grains sparsely scattered in melilite/wollastonite matrix, occasionally with minor rankite, schorlomite garnet and possibly other phases. Formula: BaCa6[SiO4)(PO40](PO4)2F, trigonal, IMA #2013-031. Elegantly prepared and thoroughly identified in a 1 cm ore section in a 1.5x1.5cm probe mount, accompanied by a color image plus backscattered SEM images at various magnifications that show the labelled phase boundaries, plus full analytical chemistry of the zadovite in a single specimen at 300.00. List alternates!


MINERALS OF USSR- Minerals First Discovered in the Former Territory of the USSR by Igor V. Pekov
This long awaited book by Dr. Igor Pekov received rave reviews when first published several years ago, written in English and complete with 184 color photos of minerals and localities, 68 SEM images and crystal diagrams. The strength of this 370 page hard cover work lies in the marvelously complete locality information lacking from so many published Russian mineral descriptions, and each description also includes excellent physical characteristics, type locality info, historical data and much more. This is a much-needed reference work @ only 59.00 plus shipping!


NEVADA MINERAL COLLECTION- Various Localities in Nevada
A nice lot of twenty-five (25) different species including many unusual items and odd-locality pieces, all from Nevada! Most are aesthetically challenged but generously sized from 3cm to 6cm across. Individually labelled, these lots are easily worth twice the price of 25 different for only 125.00!


Sometimes, we just can't resist something attractive that is only mildly related to our main field of mineralogy. We recently came across a interesting lot of water-clear faceted quartz from Brazil that had been treated by the proprietary, and permanent, Azotic process. The result is transparent gems that show a wild array of purple-blue-green color flashes in each stone! We have several different cuts and sizes, ranging from: about 7.5mm squares (2-2.5 cts each) @ 10.00, fine 10-11mm antique cushion cuts (5.5-6 cts each) @ 20.00, or larger ~15x12mm ovals (about 8 carats each) @ just 25.00 per stone. We can provide matched pairs at 2 times the single stone prices, or offer a special 50 carat lot of assorted stones @ just $135.00 - less than $3.00 a carat! Great looking material, and a suitable enhancement for Brazilian quartz gemstones!


The Pseudo News - by Dr. Phil Betancourt
We have a limited number of perfect-bound reprints of the long out-of-print The Pseudo News, a 128 page periodical that focused on the collecting of mineral pseudomorphs. A quarterly magazine that was published in three annual volumes from 1994-1996, it described finds at classic localities, as well as new finds at more obscure sites. It provided excellent technical recounting of the various types of pseudomorphs that occur in the mineral kingdom and was avidly read by a small but enthusiastic group of subscribers. Difficult to locate in full sets, we offer a complete reprint, including a comprehensive index, for just $35.00 postpaid in the U.S.A.; for foreign mailing: add $20.00.

All specimens offered on a first-come first-served basis, FOB our warehouse.

AURICHALCITE- 79 Mine, nr. Hayden, Gila Co., Arizona
Just uncovered in the warehouse: a small flat of excellent, needle-like pale blue aurichalcite from the 79 Mine, collected in 1968, wrapped, and unseen by human eyes ever since! Perhaps the finest U.S. occurrence of the mineral ever found, we have a small selection of TN sized specimens, some with hemimorphite or other minerals, all with good micro potential as well, at just 10.00 per specimen. Colorful and attractive!

AZURITE- Mechernich, "Rhenish Prussia" Germany
A very old specimen, ex-A.E. Seaman Mineral Museum and accompanied by their cardboard label, indicating the specimen was provided by L.L. Hubbard (b. 1849) who studied at Harvard, Bonn and Heidelberg. The piece shows numerous balls of pisolitic azurite protruding from a hard, sandy matrix. The azurite balls appear to run throughout the entire piece and are not a superficial coating but rather a dense "bunch of grapes" that average about 5mm across and are individually comprised of hundreds(?) of tiny azurite crystals. The "Rhenish Prussia" on the label suggests the piece was possibly early 19th century or later, as the locality is an ancient mining area now part of North Rhein-Westphalia. A rarely-encountered specimen with excellent pedigree, overall size about 5x5cm @ 175.00.

CALCINAKSITE (IMA #2013-081)- Bellerberg, Eifel District, Germany

Sizes from 2cm to 10cm @ 10.00, 20.00, 35.00, 55.00, 80.00 and a few at 100.00 each, depending on size and coverage!

CALOMEL- Redwood City, San Mateo Co., California
This uncommon mercury chloride occurs here as patches of transparent to slightly yellowish druses well scattered on rock matrix, potentially associated with other mercury-rich phases. The calomel shows good fluorescence (bright orange-red under SW UV) as well, and these specimens are quite old, recently rediscovered in an old cigar box from the Godshaw collection. Specimens range in size from about 2.5cm to 4cm @ 30.00, 45.00 and 65.00. List alternates!

CANCRINITE- Cancrinite Hill, Dungannon, Ontario, Canada
