Azurite rosette form with Malachite- historic specimen
stock #A-35-458-(397)
Chessy Copper Mine, Chessy-les-Mines, Villefranche, Rhone
Rhone-Alpes, France
5.1 x 3.1 x 3 CM (cabinet)
price: $560
Pre Holiday 2017

A remarkable classic with documented history. A very old Chessy Les Mines piece, from the collection of Wallace Gould Levison, which he obtained in 1865 from mineral dealer Chas. S. Stone of Brooklyn NY. We include for the buyer a photocopy of the handwritten journal entry for this piece. Aside from the early vintage, the specimen is quite fine in its own right, well crystallized with rare electric blue color and clustered bladed rosettes. While not critically perfect, The condition is impressively good despite a century and half of handling. Most of what at a glance look like bruises are in fact undamaged. In 1865, 15 years before Bisbee began to produce these were treasured as the worlds best Azurites. This is still a nice specimen with very good luster and form.
Wulfenite on Duftite
stock #17.1-336
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.2 x 2.2 x 2.1 CM (thumbnail)
price: $330
Pre Holiday 2017

A superb, sharp yellow Wulfenite crystal perched on a delicate matrix of bright green Duftite balls and related minerals. Great combination with wonderful color and in exceptional condition. With 20 x magnification I can just see one very microscopic bruise point that is impossible to find otherwise. Choice display specimen that has fine form and color contrast.
Apatite (Fluorapatite) with Byssolite inclusions
stock #17.1-683
Ganadao (Gandahab) Mohmand Agency
FATA Federally Administered Tribal Areas, Pakistan
4 x 2.7 x 1.2 CM (miniature)
price: $600
Pre Holiday 2017

A complete, sharp transparent alpine style Apatite prism loaded with Byssolite needles that give the transparent colorless crystal a deep green hue. Very similar in form and look to Austrian and other European cleft Apatite. There is no damage and the whole is a floater with no point of attachment. Some of the edges show very complex multi faced crystallization and a few conjoined smaller crystals.
Quartz (Herkimer Diamond- Black stem scepter)
stock #17.1-684
Treasure Mountain, Little Falls, Herkimer County
New York, United States
3.6 x 1.8 x 1.3 (small miniature/ large thumbnail (toenail))
price: $340
Pre Holiday 2017

A Northeastern US mineral legend, the black stemmed scepters of Herkimer are quite rare and despite hundreds of diggers toiling in the hard Dolomite only a few are found every few years. From a recent exceptional pocket this is a perfect example with no damage (extra rare) and doubly terminated (crudely) which is almost unheard of. The black stem is partly deep smoky brown with a few tiny areas of transparency. The top is sharp and glassy and also has dark inclusions some of which are brightly fluorescent. A fine small example of this most uncommon of Herkimer Diamond Quartz!
Fluellite with Wavellite
stock #15.1-1098-(SM4424)
Willard mine, Willard District. Pershing County
Nevada, United States
7 x 4.6 x 3.2 CM (cabinet)
price: $275
Pre Holiday 2017

A quite rare mineral not often seen for sale in esthetic specimens, this is a fine and rich specimen of Fluellite. The crystals are sharp, transparent and well formed colorless although a few have a slight yellow tinge. Balls of greenish Wavellite are present and a few other small needle crystals probably Minyulite but not verified. the crystals are in fine condition being protected in the central vug of this specimen.
Adamite (yellow, non cuprian) with Malachite, Rosasite etc.
stock #17.1-330
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.3 x 2.3 x 2 CM (small miniature/ large thumbnail (toenail))
price: $330
Pre Holiday 2017

A rare yet quite pretty Tsumeb specimen, Adamite that is not the usual Cuprian (green) variety. The wheat sheaf type crystal clusters are lemon yellow, contrasting with Malachite balls some with a tinge of Rosasite. In fine condition, no damage at all by naked eye but with 20X magnification some very tiny areas of chipping can be found, virtually perfect.
Beryl- Highly etched gem crystal
stock #17.1-296
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
8.8 x 2.6 x 2.2 CM (cabinet)
price: $1500
Pre Holiday 2017

A very odd, beautiful and choice gem Beryl that reminds of the famed Ukrainian Heliodore, yet this is an Erongo specimen. In fine condition, all sides of this crystal are stepped and etched with complex, faceted faces. Close to 100 percent facetable gem grade transparency and 44 grams of green to yellowish color, like a midpoint between Aquamarine and Heliodore. We recently (2017) obtained this in Namibia where it was the best and largest of a single pocket. So far there seems to be no more. Doubly terminated (crudely) and in our experience, unique.
Fluorite - zoned, classic yellow- purple
stock #17.1-AX-29=058
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
6.1 x 4.9 x 4.1 CM (cabinet)
price: $1150
Pre Holiday 2017

An American classic, sharp Fluorite with excellent color and form from the Minerva #1. Complex cubic stepping and hoppers on several faces and a few Chalcopyrite crystals add a nice accent. The Fluorite cubes are very sharp, in fine condition, colorful and translucent to transparent. Looks great from several angles and with backlighting is really dramatic. The photos here are NOT backlit so it looks as it will in a typical display without special lighting. Sadly such quality Illinois Fluorites are fast becoming rare and expensive. No damage except on the underside where it was attached, this is choice and clean on all display faces.
