1.97" Apache Gold Pendant with Snake Chain Necklace

Apache gold is the name for a combination of black schist and chalcopyrite. It forms when copper sulfides are buried beneath accumulating volcanic materials. The combination of heat, pressures and hydrothermal activity metamorphoses the rocks and ores into interesting waves and bands.

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.
