Calcite and Duftite (Tsumeb, Namibia)
Tsumeb Mine, Otjikoto Region, Namibia. 100mm x 70mm x 20mm.
There are bright yellow rhombehedrans of Calcite with a small surrounding partially etched white coating on them. These in turn rest on the green Duftite with all of this on the brown matrix. This is a interesting specimen from Tsumeb, quite unusual and very eye catching.
