Description: COPPER "SKULL CAP"
Keweenaw Peninsula, Michigan
Native copper can take several forms but occasionally it is found in this strange bowl, or skull cap shaped form; the cause is usually the formation of the metal around a basalt cobble. It boasts a highly textured surface both inside and out and a pleasant pale gray-green patina, with coppery brown and red and a patch on the exterior of warm burnt orange, 5 x 5 x 2 3/4 inches.
