Dioptase, Smithsonite, Calcite
Thumbnail, 2.5 x 2.5 x 1.4 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
A superb thumbnail of a cluster of extremely gemmy and lustrous, emerald-green dioptase crystals to 1.1 cm aesthetically perched on a thin wedge of sparkly light sea-green smithsonite microcrysals and beautifully accented with a couple of colorless calcite rhombs. This very interesting Tsumeb combination specimen is from the Dr. Fred Pough Collection and is older material.
