Illustrated in ExtraLapis: Calcite issue, page 8, AS THE STEREOTYPICAL EXAMPLE 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 undamage save for a very minor bruising along one edge of the lower left (that could be ameliorated with acid if desired. its so minor I wouldn't bother). This was exchanged by me recently from the well-known calcite collection of Francis Benjamin.
