Geological Background: Dioptase is a rare copper cyclosilicate mineral typically formed in the oxidized zones of copper deposits. It grows in drusy coatings of intensely coloured green crystals, which often occur in association with Calcite or Quartz. Namibia, especially the Tsumeb Mine and nearby regions, is world-renowned for yielding some of the finest Dioptase specimens.
Calcite, a common carbonate mineral, acts as a contrasting and supportive host in this specimen, enhancing the aesthetic brilliance of the vibrant Dioptase.
