I have shot this very large, superb arsenopyrite compound crystal from slightly different angles to try to capture the fantastic stepped reflections of the crystal that are evident from the display face. It has a stacked structure that is graduated towards the back to perfectly show off the dazzling luster of the faces. The termination is absolutely superb, with each small section of the compound crystal having its own mirror-like face on top, massed together in a stepped pattern with triangular forms. The piece is just about complete all around, with just some minor contact areas on the backside! A showy piece but, more than that, of extremely large size for a Chinese arsenopyrite crystal. The fact that there is a fair supply of cheap arsenos coming out of China does not diminish the desirability of super ones such as this at all. 7.5 x 6.5 x 5 cm

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.
