Bournonite, Quartz
Small Cabinet, 7.4 x 4.4 x 2.8 cm
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
A 2.6 x 1.8 cm, splendent, metallic, columnar bournonite crystal is aesthetically set on the side of a very fine cluster of transparent to translucent, glassy quartz crystals from recent finds at the Yaogangxian Mine of China. The 4.5 cm, doubly terminated quartz crystal has interesting stepped-growth faces. This excellent piece is highly representative of the species and locale.
