Dolomite cast with Calcite (Tsumeb)
Tsumeb Mine, Namibia. 35mm x 35mm.
The interior of the cast is the classic feature one generally sees however with the addition of minor Malachite. The outside of the cast was clearly first covered with Malachite and at a later stage overgrown with small clear calcite cubes. A very interesting and quite unique little specimen from Tsumeb. Packed shipping weight +/- 75gr.
