Bournonite (doubly-terminated) (ex Brian Kosnar Collection)

Item Description

This mine has become one of the foremost producers of fine quality Bournonite specimens in the world. Superb Bournonites are only found in a handful of worldwide localities, and the specimens from the Yaogangxian mine are among the best extant. This piece features a HIGHLY splendent, DOUBLY-TERMINATED, bright silvery color, metallic, prismatic crystal of Bournonite with a few smaller associated crystals along the side of the main crystal. In my experience, highly lustrous d/t Bournonite crystals are not common from any locality, and this beautifl large thumbnail is a great example of how good the quality of the Yaogangxian specimens can be. Hard to photograph and better in person. A good Bournonite for any collector.
