Pre Holiday 2017

One of the more famed Pseudomorphs from Tsumeb is Rosasite replacing Malachite that has replaces Azurite crystals. This is an excellent example with a thin outer zone of Rosasite that has several small Calcite rhombs sprinkled on the surface. Attractive and now quite uncommon, the main crystal is in perfect condition. Other crystals on the back and bottom side are broken showing the malachite core, does not affect display. A big thumbnail with a lot of good visual impact.
Anglesite
stock #17.1-693
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
2.1 x 1.3 x .8CM (thumbnail)
price: $180
Pre Holiday 2017

A transparent Tsumeb Anglesite crystal with the look of a Moroccan specimen. Smokey cognac color and zoning a well as unknown inclusions add a nice look to this crystal. On close inspection the association of Chalcocite and Posnakite micros and the unusual face coatings confirm that this is from Tsumeb. Glassy and sharp, there is some light edge bruising but the crystal is complete and terminated. A less common form and habit this is an early vintage piece much better in person.
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.
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.
Smithsonite- Cobaltoan
stock #17.1-329
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.2 x 1.6 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $360
Pre Holiday 2017

The rare intense color most desired for a fine Cobaltoan Smithsonite. Well crystallized and in perfect condition this is a classic Tsumeb specimen with first rate esthetics. Rich purple-pink hue and 360 degree display ability give this thumbnail top marks. Choice and better in person.
Smithsonite (Pink Cobaltoan)
stock #17.1-337
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.2 x 2.3 x 1.3 CM (thumbnail)
price: $250
Pre Holiday 2017

Pink gemmy crystals of Cobaltoan Smithsonite in on a perfect condition thumbnail. From the great Tsumeb mine, this looks better in person, has the rich, lustrous color that is the most desiarable. The better Tsumeb pink Smithsonites are the worlds best, this small specimen show why.
Smithsonite with Cerussite and Calcite
stock #17.1-333
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.6 x 2.3 x 1.7 (small miniature/ large thumbnail (toenail))
price: $290
Pre Holiday 2017

This specimen is one of a kind, a unique Tsumeb oddity with great esthetics. An elongated, gemmy crystal of Smithsonite rises from a gossan matrix and hosts a few gem clear smokey Cerussites. The Smithsonite shows signs of being a compound crystal with parallel growth but a single termination. The Cerussites and a tiny part of the Smithsonite (only seen with magnification) are chipped but this is on the "back" not visible on display, the front and side view are pristine undamaged. Tiny Calcites with some odd habits are also scattered on the matrix. The crazy composition of this specimen is typical of why so many collectors love Tsumeb minerals.
