Cuprite- gemmy red crystals
stock #16.1-640
Milpillas Mine, Cuitaca, Municipio de Cananea
Sonora, Mexico
6 x 4.4 x 1.7 CM (cabinet)
price: $520


A well formed, bright stack of Cuprite crystals from the great Milpillas mine, better known for world class Azurites. This find of Cuprites created a big stir 2 years ago, but few were undamaged or had crystals much over a few millimeters. This piece is far better than average, in excellent condition damage wise and the crystals are stacked in an esthetic epitaxial arrangement. These octahedrons all will glow bright red with focused light passing through them, the photos here are only made with typical display lighting, so as not to be misleading. When these were first found the prices being charged were incredibly high, this is a lot more reasonable, yet a fine quality piece, by comparison a really good value.
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


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!
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


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.
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


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.
Azurite rosette form with Malachite- historic specimen
stock #A-35-458-(397)
Chessy Copper mine, Chessy-les Mines, Le Bois d'Oingt, Rhone
Rhone-Alpes, France
5.1 x 3.1 x 3 CM (cabinet)
price: $560


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.
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


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.
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


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.
SOLD Semseyite w. Galena
stock #SOLD 16.1-458-CN3610
Baia Sprie
Maramures, Romania
6.1 x 3.9 x 3 CM (cabinet)
price: $0


Semseyite is normally not pretty, but this is. Typically Semseyite is seen as a few tiny sprays on a big mass of Galena, but this is almost pure Semseyite with only tiny bits of Galena. Super rich and in excellent condition, well crystallized on all sides and very bright. The metallic luster is far better than normal for this usually dull rare mineral. Ex Charles Noll collection, and really choice.
