Summary

Description
English: Calcite, Copper
Locality: Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia (Locality at mindat.org)
Size: small cabinet, 6.6 x 4.9 x 4.7 cm
Calcite (sharp rhombohedron on Copper)
Illustrated in ExtraLapis: Calcite issue, page 8, as the stereotypical of a sharp calcite rhombohedron in a discussion of the forms of calcite, this is a truly spectacular example of the classical rhombohedral form of calcite, from Tsumeb. The huge calcite rhomb is colorless, lustrous, transparent, and measures to 4 cm on edge. The matrix of copper has a green patina, and is laced with tiny copper included calcite crystals. This is an elegant calcite matrix piece from the heyday of Tsumeb. It is perfect in form and symmetry and undamaged save for a very minor bruising along one edge of the lower left. This was exchanged by me recently from the well-known calcite collection of Francis and Patricia Benjamin.
