No, this is not a Flambeau (Wisconsin) chalcocite, but an old BUTTE chalcocite, quite hard to find on the market! This piece came out of Gary Hansen's old dealer stock and still has his label with it. The crystals are rather crude, but for the locality it is a good piece, and these just are not around! 7 x 4.3 x 2.7 cm
