    DIOPTASE
    Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto Region (Oshikoto), Namibia

    There is no one on this planet who doesn't instantly love Dioptase. Something magical takes place when you see this stunning Copper mineral - especially for the first time. Chemically, Dioptase is a Silicate of Copper, but not a common one. The best sources are African, with Kazakhstan running in second place. Historically, the most famous locality is the Tsumeb Mine in Namibia, but the mine is now exhausted and closed. That is where this enormous plate was mined many, many years ago. It displays classic Tsumeb style with hundreds of stout crystals of a transparent blue-green hue completely covering a Calcite matrix plate of typical reddish-brown color. The luster of the many crystals is brilliantly glassy, and the condition of the piece is excellent. This fine mineral classic, (which may also be seen as zoomorphically resembling a poodle), comes with a custom acrylic base.
    Overall Measurements: 8 x 6.5 x 2.0 inches (20.2 x 16.7 x 5.1 cm)
    Offered at no reserve.

    It would indeed have been much simpler to work with a local auction house, and we had local options. But we never once regretted going with Heritage.
