Inesite with Quartz, Hubetite etc.
stock #16.1-174
Fengjiashan Mine (Daye Copper Mine), Edong District, Daye County, Huangs
Hubei, China
7.2 x 7 x 5.2 CM (cabinet)
price: $390
Winter 2016-17

A fine Chinese Inesite from the Daye mine (Fenguashian Mine). Great esthetic with a very delicate, perfect standing spray of Inesite on top of a matrix of smaller Inesite, Quartz and Hubeite crystals. Excellent form and color, this has the richest red-orange hue that is most desirable. Not much has been found in recent years and little of that has good form or color. An impressive specimen for the mineral and for the locale.
Dioptase (well crystallized for type locality)
stock #15.1-945- (SM1939)
Altyn-Tyube, Kirghiz Steppes
Karagandy Province, Kazakhstan
6.8 x 4.5 x 4.6 CM (cabinet)
price: $690
Winter 2016-17

A bright, striking Dioptase with sizable, perfect emerald green crystals on a etched matrix. From Altyn-Tyube, this is of exceptional quality for that location, and in fact is a choice specimen from anyplace else too. Sharp perfect crystals to 1.3 CM long are clustered in a sizable mass, a few micro tufts of Malachite are also note. Most Altyn-Tyube pieces have much less visual impact.
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.
HOLD Chrysoberyl (Alexandrite) -twined sixling habit crystal
stock #HOLD 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.
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 #17.1-AX-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.
