Tucson, Arizona, USADioptase is always a very popular mineral amongst collectors because of its attractive intense emerald-green colour and bright glassy lustre making its crystals look like gemstones. The very best crystals for their lustre are those from the famous Tsumeb mine in Namibia and although larger crystals have been found elsewhere in other deposits in Africa their overall quality never touches those of Tsumeb. Another feature in favour of Tsumeb Dioptase is its frequent association with white Dolomite or Calcite, producing an exceptional contrast in colour that really enhances the Dioptase crystals further. Getting the perfect balance of crystal size, crystal shape, colour, lustre and white matrix is the challenge, and one which few specimens achieve. This absolutely stunning cabinet-sized display specimen hits the mark on all of the above, with crystals reaching an impressive (for Tsumeb mine) 1.5 cm in length with amazing intensity of colour, remarkable glassy surfaces, superb transparency and with a great white background. Very few Dioptase specimens in the world can rival this one for its overall quality. It comes with a custom-made Sunnywood acryllic display stand.
