Another nice old specimen from the Michigan copper country. This is a very nice native copper specimen with very well-formed crystals to 1.5cm long. The specimen appears to have modified dodecahedron and spinel-law twinned crystals. These copper specimens from Michigan are old, with most mines having closed prior to 1930's.
