Sphalerite (ex Rich Kosnar collection)

Item Description

The Camp Bird mine near Ouray, Colorado is one of the most classic of all the Colorado ore body localities. It is renowned for its superb sulfide specimens. This specimen features superb quality, sharp, lustrous, jet-black crystals of Sphalerite up to 1.1 cm across associated with bright metallic Chalcopyrite plus gemmy Quartz crystals. The underside of the specimen is filled with micro olive-green Epidote and small white crystal groups of scalenohedral Calcite. This is a superb Sphalerite from this most classic of San Juan localities. These specimens are impossible to obtain these days, and are regarded among Colorado collectors as some of the best from the state. This piece came to Rich Kosnar from noted Colorado collector, George Robertson.
