Calaverite with Gold (fine crystals) (ex Rich Kosnar Collection)

Item Description

The Cripple Creek District in Colorado was one of the most prolific Telluride producing mining districts in the United States. Telluride species from this area are highly sought after by collectors, and it is well justified as some superb examples are known from the various mines in the area. This specimen hosts excellent, sharp, highly splendent, tabular, striated, monoclinic crystals of the rare gold telluride, Calaverite which have a bronzy hue are are associated with micro specs of Native Gold. These specimens are very difficult to obtain, and considering that the majority of them were mined over 100 years ago, the only source for specimens is old collections.
