Beverly Hills, CA, USALive Auction
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.
