A large and very hackly mass of Native Copper partially encapsulated within white Calcite from No. 6 shaft, Centennial mine, Calumet Township, Houghton County, Michigan. Although not the sought after blocky, or dendritic Native Copper crystals known from some of the Michigan mines, this is nevertheless a very rich aggregate of bright metallic Native Copper and displays the classic sharp, hackly, bladed form seen in natural copper. Ex David Hardman collection, no. 312.
