Chalcopyrite & calcite, Hunan province, China
description: T 3" ac. A cluster of moderately lustrous, skeletal crystals of chalcopyrite complimented by sharp, disk-shaped crystals of white calcite. This little known mine in Hunan province has undoubtedly produced some of the world's best examples of chalcopyrite. I bought this piece from Gene Schlepp during a visit to Tucson in late 2012.
