Arsenopyrite with Calcite
Yaogangxian Mine, Yizhang Co., Chenzhou, Hunan, China
Miniature, 4.7 x 3.0 x 2.9 cm

A remarkable Arsenopyrite from the Yaogangxian Mine that continues to surprise with a variety of great mineral specimens such as this one! This cluster of Arsenopyrite consists of several complex crystals in parallel or subparallel growth that display a metallic peacock colored, iridescent tarnish and are associated with contrasting small Calcite crystals and a single, small Quartz crystal on the backside. From a small pocket with this insane natural iridescence, that came out in June or July of 2019.
