An iridescent cluster of chalcocite showing purples, blues, and bronze, these being caused by a coating of bornite. There is some contact on the backside and minor dings throughout. This specimen comes from the now closed Flambeau Mine in Wisconsin, and is the most important find of this species in North America. The property was operated by Kennecott up through 1997 and has now been completely reclaimed and revegetated. No specimens will likely ever come from this mine again.
