Iridescent chalcopyrite (Mexico)
PUMI1747-3
It is a mineral of hydrothermal origin, which is part of the copper sulphides and is exploited as a source of copper ore, especially for alloys. This massive block comes from Mexico. Its incredible colors are an oxidation of its metallic surface, and it occurred over thousands of years with the air and water that eventually penetrated the mineral. But the result is beautiful!
This mineral is present in meteorites, and... on a brass base!!
