2.5" Striking Green Conichalcite with Clinoclase - Namibia

This is a beautiful formation of striking green conichalite microcrystals that formed as botryoidal aggregates. One side of this specimen contains deep-blue aggregates of clinoclase. It was collected near the city of Opuwo in the Kunene Region of Namibia.

Conichalcite is an arsenate mineral that forms as a secondary mineral in the oxidized zones of copper deposits. Often it will bear a vibrant green color, though it will display a variety of colors from grass-green to yellow-green. It's the arsenic-rich end member of the series and calciovolborthite is the vanadium rich end member.

Conichalcite contains a significant amount of poisonous arsenic, making it somewhat toxic. Therefore, washing hands following handling of conichalcite specimens, is recommended.

Chemical formula: CaCu(AsO4)(OH)
