2.25" Chalcopyrite Specimen - Missouri

This is a multi-colored, metallic specimen of Chalcopyrite from the Sweetwater Mine in Missouri.

Chalcopyrite is a brass-yellow colored mineral and an important copper ore. When weathered, chalcopyrite loses its metallic luster, turning a gray-green color. When exposed to acids, the tarnish can develop a red, blue, or purple iridescence: this acid-treated material is often sold under the name peacock ore.
