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 Chalcopyrite specimens, exhibiting some of the finest twins for the species extant. This specimen features dozens of sharp, splendent, metallic, brassy-gold colored twinned crystal of Chalcopyrite with associated lustrous black Sphalerite. This is a superb Chalcopyrite 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.
