Excellent specimen featuring several large, well-formed, isolated dodecahedral copper crystals with superb patina on matrix from the Phoenix Mine, Phoenix, Keweenaw County, Michigan, USA. A great copper for the Phoenix mine, with atypical crystal form for the locale, and exceptional provenance, passing from the E.D. Drown collection to the Philadelphia Academy Collection, likely in the mid-19th Century. Classic!
