Mottramite, Calcite
Miniature, 4.8 x 4.1 x 3.8 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
A classic specimen from Tsumeb of deep olive-green mottramite forming botryoidal aggregates with the classic "greasy" luster which are overgrowing and associated with white to colorless calcite crystals. Some of the calcites are nearly water-clear, and the overall balance and aesthetics of the piece make it a good miniature size specimen from this most renowned of localities. Ex. Richard Kosnar Collection.
