Striking specimen of grass-green Malachite decorated with colorless Calcite from this famous locality – Tsumeb Mine, Namibia. The Malachite grows in very small hairy needles with intense and very saturated dark green color. The sharp rhombohedral Calcite crystals are transparent, glassy and lustrous. Small dark spheres of an unidentified mineral grow on the Calcite. Some nicks and contacts., Amazing!
