Dioptase (Tsumeb, Namibia)
Tsumeb Mine, Otjikoto Region, Namibia. 80mm x 60mm x 40mm.
This is a large piece of Dioptase, while there is damage on the fron face from where it was removed the cavities are lined with perfect and well formed Dioptase. It makes for a stunning cabinet display specimen and is a real classic from Tsumeb indeed.
