A fine display of spiky translucent inter grown Smithsonite crystals from the one and only Tsumeb Mine, Namibia. Three faces steeply pyramidal crystals of colourless-white Smithsonite crystals measure to 5mm +, with faintly striated faces. The Smithsonite crystals cover ridges and hollows of a metallic grey sulphide matrix. A neat specimen of Smithsonite from Tsumeb.
