This Flambeau Mine find is still considered one of the most important chalcocite finds ever. These spectacular pieces came out during just a few shhort years of working, after which the mine was closed and literally reclaimed over....it's gone! Someday, people will look back and realize that these were one of the great US classic finds of the era. This large specimen has absolutely HUGE compound crystals; essentially, the specimen is a series of stacked whorls of fanned shiled-like crystal, of an iridescent purple and gold. The colors are beautiful, and more apparent in person. The compound crystal on top measures over 5 cm across! An extremely impressive specimen from an important find. BETTER In PERSON! 6.5 x 5.5 x 5 cm
