Tsumeb, Namibia, Calcite

Calcite is not a rare mineral in the world. Well crystallized specimens are not all that common, though! Calcite occurred in beautiful specimens from Tsumeb, as an accessory mineral. Here are some very nice reasonably priced examples.

  • This super plate of calcite crystals shows razor-sharp calcite rhombs with a creamy-white colour. Very lustrous! As well, the calcite crystals have a dusting of tiny green crystals that I believe are duftite. Shows well.
