- Flambeau Mine, Ladysmith, Rusk Co., Wisconsin, USA
A showy and excellent, two-sided thumbnail cluster of sharp, iridescent, brassy chalcocite crystals from the famous Flambeau Mine of Wisconsin. This high-grade copper mine operated only from 1993-1997. These are considered to be some of the best United States chalcocites. The one contacted area REALLY shows the beautiful iridescence.
