Spectacular coloring of this rich patina really enhances this weirdly/interestingly/curvaceous/chocolatey/crudely crystallized copper specimen from the Keweenaw peninsula of Michigan. I really cannot describe the crystallization any other way - see the pic. Neat beast of a copper, whatever you call it! The bright red coloration in the copper itself is from cuprite. There is also a fair amount of malachite and calcite encrustations on parts of the specimen, which adds to the character of the piece.
