At 6.4 pounds, this would be a large and surprisingly pristine Tsumeb calcite even if it were just plain old typical white rhombs. But it is more interesting because of the very unusual oriented inclusions of hematite granules embedded within certain edges and edge corners. We call this a preferential coating or preferential deposition effect. In person it is very striking for the incredible geometry it creates, and the thin brown-red lines create a sharp boundary between the calcite rhombohedra which makes the whole piece more dramatic. Ex. Willy Israel Tsumeb Collection, purchased from Clive Queit in October of 1978.
