A classic Tsumeb formation of slightly smoky coloured Calcite included by Duftite. Crystals of rhombic Calcite are sharply formed measuring to 3.6cm on edge, in a part parallel growth habit. Mid-green Duftite has been deposited over much of the display face of the specimen, which in-turn has been covered in a thin veneer of colourless Calcite. Spotted over the Calcite crystals are spherulites of green Malachite.
