Very rare combination of Dolomite, Tennantite, Smithsonite, and Quartz. The Tennantite is the first layer on the matrix, and it consists of lustrous, stepped crystals (similar to Hausmannites from the Kalahari). Coating that layer are rare (for Tsumeb) Quartz crystals, upon which are yellow Smithsonite rhombs that occur in clusters up to 2 cm across. The final addition to this specimen is a layer of sparkly, drusy yellow Dolomite that coats the entire back side, as well as the Smithsonites preferentially. On top of that, the Dolomite is fluorescent. Mineralogically, this is an interesting combination piece
