Ettringite, Calcite
Small Cabinet, 7.0 x 3.1 x 2.6 cm
N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa

A unique piece with sparkling, gemmy, jewel-like gem ettringite crystals sprinkled upon a cluster of unusually elongated spear-like calcite crystals. The calcite is also unusually high in luster, so the two complement in luster and contrast in color. Ex. Charlie Key.
