Chalcopyrite iridescent crystals (USA)
PUMI1738
Iridescent Chalcopyrite crystals on a matrix of grey dolomite crystals. This sample comes from the state of Missouri in the United States. Specifically from Sweetwater Mine. This ore is mined to make copper alloys. But if you simply contemplate it: the spectrum of colors it can take is just incredible.
