A neat crystal specimen of Calcite from the Tsumeb Mine, Namibia. The lustrous Calcite crystals form excellent stacked habit to 2.5cm tall. The crystals are mostly colourless gemmy with translucent areas. The Calcite crystals have grown on a druse of rhombic Calcite, with sparkling lustre. The drusy Calcite itself covers a matrix of convoluted green Duftite and Goethite. The specimen stands to display the Calcite crystals to advantage.
