Cuprite Var. Chalcotrichite with Smithsonite. Dolomite etc.
stock #15.1-430
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
4 x 3.4 x 3.2 CM (miniature)
price: $285
Winter 2016-17

A neat Tsumeb oddity! A large "blob" of Chalcotrichite composed of tiny hairlike crystals and masses that has a vug in its middle holding Dolomite crystals. A few small cuprian Smithsonite crystals are a nice accent on the matrix. Tsumeb is famed for the rare but beautiful Chalcotrichite included in carbonate minerals (ie. inside calcite or Cerussite) but I have never seen a crystallized carbonate mineral included in Chalcotrichite!
Rhodonite -well crystallized, classic specimen, unusual locale
stock #15.1-1024-(SM-2208)A
Harstigen, Pajsberg (Persberg)
Varmland, Sweden
8.4 x 6 x 4.4 CM (cabinet)
price: $700
Winter 2016-17

An incredible Swedish Rhodonite with excellent color, sharp crystals and fine pedigree. Ex University of Chicago collection with original label noting this was a donation by George English, likely well over 100 years ago. Several crystal lined vugs are on the matrix, the largest being 5.5 CM across. Some broken crystals are noted but not very evident without magnification, overall the condition is quite good especially given the age of this piece. From a small but noted old Iron mine, there are some tiny orange garnet crystals (likely Grossular), Diopside and an unidentified black mineral in the mix. We have not seen another with such good esthetics and the color is a rich red and not the typical pink.
Chrysoberyl (Alexandrite) -twined sixling habit crystal
stock #13.1-071
Carnaiba Mine, Pindobacu, Campo Formosa
Bahia, Brazil
4.2 x 3.8 x 1.7 CM (miniature)
price: $450
Winter 2016-17

A distinct, dark green sixling twin crystal on matrix from Campo Formosa. This flat habit star twin is complete and in very good condition as seen. With strong light translucent and clear areas are seen but overall this is opaque. A sizable crystal this is 4 CM across and has classic form. Some slight color change can be seen with daylight versus incandescent. These are no longer being found as of our last trip to Bahia (2016). This specimen is from finds in 2011.
Elbaite on Lepidolite
stock #13.1-339
Santa Rosa Mine, Itambacuri
Minas Gerais, Brazil
3.8 x 2.4 x 2 CM (miniature)
price: $80
Winter 2016-17

A colorful jumble of green Elbaite crystals offset by bits of purple Lepidolite. Very nice luster, moderate damage as seen on some crystals keeps this a very affordable specimen.
SOLD Babingtonite with Prehnite etc.
stock #SOLD 13.1-348
Roncari Quarry, East Granby, Hartford County
Connecticut, United States
3.4 x 2.2 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $0
Winter 2016-17

A killer small miniature from the Roncari Quarry, which is not well known for Babingtonites. A perfect, sharp and very lustrous doubly terminated crystal sits on mint green Prehnite. The Traprock quarries along the Connecticut river are classic localities for Zeolites, Calcites, Datolites and Babingtonite. The Roncari quarry only rarely produced Babingtonite, mostly small, blocky and dull. The rare exceptions however can be very esthetic and this piece is unusually fine for the location, distinctly different from the recent Chinese Babingtonite habits. A nice American classic.
Corundum var. Sapphire
stock #16.1-658
Mogok, Pyin-oo-Lwin District
Mandalay division, Myanmar (Burma)
2.5 x 1 x .9 CM (thumbnail)
price: $320
Winter 2016-17

A pair of Sapphire crystals are perched on each other showing perfect textbook form. This shows the classic habit with lightly frosted faces, translucent with some transparent gem areas. Almost colorless with a faint blue to yellow hue, this is complete, a floater and undamaged. A choice thumbnail with far better form than is typical.
Cubanite- Exceptional twinned crystal on matrix
stock #Alec 23-008
Henderson Number 2, Chibougamau
Quebec, Canada
6.5 x 4.8 x 2 CM (cabinet)
price: $4000
Winter 2016-17

A perfect, undamaged sixling twin with brilliant luster perched on contrasting dark matrix. From the only find that ever produced good crystals, very few perfect ones were ever found and few of those were on matrix. Now that the mine has been closed for years specimens of this calibre are only rarely available from old collections. Textbook form and top quality for the species. While this is a good deal more expensive than other Cubanites we offer, this is certainly in a class by itself.
Fluorite (spherical), Calcite and Quartz
stock #15.1-926-(SM-5191)
Mahadari, Sinnar, Nasik District
Maharashtra, India
9.8 x 5.9 x 6 CM (cabinet)
price: $425
Winter 2016-17

A nice epitaxial combo specimen from the Deccan Plateau with odd but attractive esthetics. A main Calcite crystal has small spheres of Fluorite some coated by Calcite that are growing only on the crystal edges but not on any faces. Larger spheres of Fluorite and Quartz forms the matrix. In fine condition.
