CALCITE & NATIVE COPPER, Keweenaw Peninsula, Michigan.
CALCITE & NATIVE COPPER, Keweenaw Peninsula, Michigan. Despite my poor photographs this is a choice, classic example of native copper as inclusions in well-crystallized calcite and crystalline-leaf native copper on that calcite; and it is of large, important size. Measures 5x3x3 inches. Price $3,500.
