Arsenopyrite as a species usually does not give us surprises as collectors but this recent pocket of spectacular specimens is notable, even amongst previous finds. Superb, iridescent, peacock-colored Arsenopyrite crystal cluster from the Yaogangxian Mine in China! This handsome miniature has lightly striated Arsenopyrite crystals to just over 2cm in length and are completely bathed in yellow, blue and purple iridescent colors that command attention! It is a well composed and well balanced cluster that is exclusively Arsenopyrite. The bottom of the piece shows the typical metallic, tin-white color of this iron arsenic sulfide. A stunner! From a small find at the end of 2019.

Arsenopyrite from Yaogangxian Mine, China
Yaogangxian arsenopyrite is one of the great modern examples of a species that collectors once tended to treat as an accessory. At this Hunan tungsten-tin mine, arsenopyrite can be the star: steel-gray to battleship-gray crystals in sharp prismatic wedges, flattened “diamond” forms, doubly terminated parallel groups, and chunky metallic plates that have the visual weight of ore and the geometry of display-quality crystallization. The best pieces are not merely “arsenopyrite present”; they show crisp, architectural crystals standing on quartz, muscovite, fluorite, or mixed sulfide matrix with enough contrast to read from across a cabinet.
