Tsumeb is noted for the wide variety of colors and forms of its wulfenites. This piece is a striking specimen featuring bright orange, sharp, lustrous tabular Wulfenite crystals measuring up to 7 mm sitting on almost porcelain like, rhombic, sharp, lustrous Dolomite matrix. The color is as bright as any Wulfenite crystals I have seen from Tsumeb. Ex. Rob Smith Collection.
