Very fine cuprite on calcite from Tsumeb mine, Namibia. These fine gemmy cuprite crystals have no hint of silver oxidation, so it would appear that if kept out of direct sunlight they will stay this way indefinitely. The cuprite crystrals sit on snow white calcite crystals, there is also an area, mainly towards the front of the piece, that features small pink transparent rombs, I am not sure what this mineral is, possible cobaltian dolomite or cobaltian calcite.
