Bournonite (Doubly-Terminated)
Miniature, 5.1 x 2.3 x 1.6 cm
Yaogangxian Mine, Hunan Province, China
This is a large, doubly terminated, battleship-gray, mirror-bright bournonite crystal. A small amount of edge damage is present on the back, or non-display side and near the base on the front side. However, the size of the crystal along with its relative rarity overcome the damage. In person, the damage is minimal and the aesthetics oustanding.
