Aragonite With Copper Inclusions
Manto Cuba Mine, Inca de Oro, Chanaral Province, Atacama Region, Chile
Large Cabinet, 20.2 x 9.3 x 7.9 cm
Ex. Philadelphia Academy of Natural Sciences
This is a beautiful specimen, pure and simple. Regardless of anything else. The surreal blue color looks fake, painted. However, the color is actually due to copper inclusions. Note the obvious presence of a rare green mineral in small, sharp crystals: probably libethenite or brochantite. Both are found at the mine, and I have a sample sent out for analysis now.
