Of the 335 recorded mineral species from the Tsumeb mine in Namibia there is just one which has become synonymous with the locality and that is the copper silicate, Dioptase. In the higher levels and early years of mining at Tsumeb, Dioptase was scarce and is seldom seen in early collections. It was only when the second Oxidation Zone was encountered at depth that dioptase took centre stage, following a one-off spectacular find where large cavernous chamber-like vugs were lined with world class Dioptase crystals, often over growing snow-white Calcite. At the time thousands of first-class specimens hit the market in the late 1970s and early to mid-1980s, a seemingly never-ending supply. But end it did and where have they all disappeared to? Seemingly into the woodwork as it is said. Collectors of any persuasion still covert these specimens, be they Tsumeb specialists or not, simply for this unique colour and splendour. Having given this build-up, it is a good job this is a superb specimen! Deep emerald green Dioptase crystals to 1 cm completely cover an elongated light creamy grey Dolomite matrix tinged characteristically like pink in parts. The Dioptase is transparent to translucent with all crystals being highly reflective with a brilliant glassy lustre.
