4.4" Brilliant Peacock Ore - Mexico
This is a large, flashy piece of peacock ore from Mexico. Like the eponymous bird, this mineral displays a wide variety of colors. This specimen appears to have some calcite associated with it.
Commonly referred to as Peacock Ore due to its brilliant iridescent coloration, this mineral is actually acid treated chalcopyrite. This acid treatment mimics a natural process that creates the much rarer copper-based mineral Bornite.
Chalcopyrite is a brass-yellow colored mineral and an important copper ore. When weathered, chalcopyrite loses its metallic luster, tarnishing and turning a gray-green color. When exposed to acids, that tarnish can develop a red, blue or purple iridescence.
