Chalcopyrite, Bournonite
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
Miniature, 4.2 x 4.0 x 2.9 cm
Lustrous, brass-yellow, stepped-faced, helmet-shaped chalcopyrite crystals to 1.2 cm are aesthetically scattered on scintillating bournonite blades on this fine specimen from the Yaogangxian Mine of China. The bournonite crystals are incredibly bright. Very unusual, like acicular bundles. This makes them super-bright.
