A rich somewhat segmented ridge-like formation of Mottramite from the Tsumeb Mine, Namibia. The lustrous light khaki green Mottramite displays a lightly botryoidal surface, partly over grown here and there by druses of white sparkling Dolomite crystals. The internal structure of the specimen shows a concentrically banded look. The base of the specimen has a cavity lined with possible light green Conichalcite and green Malachite, with further Dolomite. A fine Mottramite from Tsumeb.
