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.
Beryl V. Aquamarine with Quartz and Schorl
stock #16.1-321
Erongo mountain, Usakos and Omaruru districts
Erongo region, Namibia
5.2 x 5 x 3.4 CM (cabinet)
price: $360
Winter 2016-17

Nicely composed specimen presenting a sharp 4.2 CM Aquamarine. No damage, the Aqua has a almost colorless gem clear tip and a deep blue lower section. A small shiny Schorl crystal is protruding from the Beryl. The Erongo area still produces many specimens so the prices of these pieces tend to be relatively lower than from other locales. This one is much better than typical material, in perfect condition, a good value.
Adularia - Classic alpine Manebach twin w. iridescence
stock #15.1-933-(SM2772)
St Gotthard, Central St. Gotthard Massif, Leventina
Ticino, Switzerland
8.3 x 5.1 x 3.8 CM (cabinet)
price: $385
Winter 2016-17

A large and fine old Swiss Orthoclase crystal that is a well formed Manebach twin with fine edge striations. Several older labels included date this back to the 19th century. This Adularia is very large, translucent to transparent and with textbook perfect form. From just the right angle the fine striations make an interesting display of diffraction colors and shows a rich iridescence. Classic and impressive.
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.
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 Cuprite Var. Chalcotrichite with Smithsonite. Dolomite etc.
stock #HOLD 15.1-430
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
4 x 3.4 x 3.2 CM (miniature)
price: $257
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!
Elbaite (bent, doubly terminated crystal)
stock #15.1-971-(SM-723)
Gilgit, Gilgit district
Gilgit, Northern Areas, Pakistan
7.5 x 3.3 x 2.6 CM (cabinet)
price: $485
Winter 2016-17

An odd but very attractive, zoned Tourmaline crystal that is clearly bent. Doubly terminated and with three color zones this in fine condition. A cluster of Cleavlandite blades is the only matrix. One termination is an uncommon slanted habit. This is an early Pakistan specimen from some of the earliest finds (1970s) that looks a bit like later Stak Nala material, but is from Gilgit area. A good value for a rare habit and nice esthetics.
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.
