Size: 9.5x7x7 cm
Species: Calcite, Copper
Locality: Quincy Mine, Houghton County, Keweenaw, Michigan, USA
Description: A large well defined calcite crystal with crystallized native copper on the exterior and minor copper inclusions. It is unusual to have such a large and well defined calcite from this locality. An absolute American classic. I note a few minor chips on the edge of the one crystal. Ex: Richard K. Smith
