Miniature, 3.9 x 2.7 x 2.0 cm
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
Until they were found at the Yaogangxian, large crystals of bournonite such as this were exceedingly rare and expensive if you could find one, from anywhere. These have sort of amazed everyone. The only detraction is that most have a lot of damage - but this one has only minor wear, is complete all around, and has a wonderful termination! 3.9 x 2.7 x 2.0cm
