4.4" Brilliant Peacock Ore - Mexico

This is a large piece of very colorful peacock ore from Mexico.

Commonly referred to as Peacock Ore due to it's brilliant iridescent coloration, it is acid treated Chalcopyrite. This acid treatment mimics a natural process which results in the much rarer copper based mineral Bornite.

Chalcopyrite is a brass-yellow colored mineral which is one of the most important ores of copper. When weathered chalcopyrite loses it's metallic luster, turning a gray-green color. When acids are present the tarnish can develop a red to blue to purple iridescence.
