Excellent and quite attractive in shape and sparkle, this large Smithsonite is from the great Tsumeb Mine. It is very unusual in several ways! The underlying matrix is a flat, tabular layer of brownish-black crystals (Tennantite, perhaps), which is first overgrown by a layer of pink (Cobaltian) Smithsonite in which the crystals completely coat the matrix. This pink Smithsonite then grades into a well-crystallized layer of pinkish-tan crystals (colored by iron or cadmium or both, perhaps) that are distinctly different and notable in their own right. They are RAZOR-sharp. These Smithsonites range up to 1.1 cm, and their curved rhombs with striations and high luster are classic in style for Tsumeb, but of unusually high sharpness and quality. Beyond that, looking into the sides of the crystals, you discover that they are exceptionally gemmy for this habit. This cabinet-sized piece is completely covered by hundreds of these second generation Smithsonites, and it displays perfectly when set on the bottom, standing up proudly and complete all around. The quality is choice, and the two distinct colors of Smithsonite add even more to the impressive aesthetic of this piece. Smithsonite is one of Tsumeb's signature species, and this is an unusual and highly desirable example of not one, but two varieties in one specimen. This is from the Stoudt collection, from specimens purchased in the 1980s-90s, generally.
