TS180 - Azurite $ 550 Tsumeb, Namibia miniature - 3.2 x 1.7 x 1.2 cm ![]() ![]() ![]() Sharp and lustrous Azurite crystal with a rare serrated habit. The crystal is a uniform 5mm thick and a deep translucent blue when backit. I put a light behind the crystal in one photo to show the translucency. Ex. Carl Acosta collection.

A complete floater with minor amounts of attached Graphite. Translucent blue with a really nice formation, way better than most from the find which were mostly irregular massess of crystals with damage along the edges.
