Excellent inter grown sharply formed rhombic crystals of Calcite measuring to 2cm, from the Tsumeb Mine, Namibia. Crystals of translucent Calcite are preferentially coated mostly on two faces by glistening sugary druse of white-colourless, second phase of Calcite deposition. Deposited with the last Calcite are gemmy-translucent Dioptase crystals measuring to around 2mm. The specimen is a classic of this habit form from the Tsumeb Mine.
