Cerussite crystals in several habits with an unknown inclusion that gives a yellow-orange color. The matrix is typically complex and very three-dimensional. Tsumeb Cerussites were found in every imaginable form and sometimes colored by inclusions. This color is very unusual, and we have not seen this before. Under strong magnification the inclusions appear to be fibrous and aligned along the crystal axis. With Tsumeb minerals mysteries are a big part of the fun. The condition of this piece is also remarkable, there is no damage even though the Cerussites are well-exposed and prominent.
Incredible form, with large sharp crystals showing classic Azurite shape covered by silky Malachite. In exceptional condition, the biggest crystal in this cluster is textbook habit, doubly terminated and 6.3 CM long. A few areas of Azurite remain, with Balydonite and Olivenite present as well. Ex N.Collins and A. Edwards collections. Impressive display impact, in clean undamaged condition, this is a top quality Tsumeb piece likely from the 1920-30 vintage years.
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.

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.

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.

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.
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.
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.
