Mineral: Azurite stalactite
Locality: Bisbee, Warren District, Mule Mountains, Cochise County, Arizona, USA
Description: At the "Mine to mine" exhibition in Munich 2017, I had the opportunity to photograph this original stone, in fact a very aesthetic cross-section of an azurite / malachite stalactite. It is from Bisbee, the famous Arizona locality. Curiously the center of azure blue candles is lined with a green central part of malachite. The latter results from a late pseudomorph of the primary azurite, arrived by the central channel. It is the same with the malachite rim that envelops the section.
