A very fine and aesthetic, complete-all-around, cluster of Bournonite crystals from the famous Yaogangxian Mine in China. The crystals, both big and small, have classic form. The metallic, bright faces range from smooth to striated, and the termination is smooth and sharp. The is a teeny tiny bit of edge wear, which is not unusual for the species or the location, but it really does not detract from the aesthetics of this fine thumbnail.
