- Stannite, Arsenopyrite
- Miniature, 3.4 x 2.7 x 2.2 cm
- Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
A showy and uncommonly fine Chinese combination specimen of a SUPER, 1.4 cm, ball-like cluster of bright, metallic-gray stannite crystals attractively attached to a brassy, highly lustrous and striated arsenopyrite crystal. Four more smaller stannite balls are an outstanding compliment. The stannites show individual faces instead of the usual jumble you see from here, and this mine has produced the best in the world recently I would say. These are REALLY GOOD stannite crystals.
