Sharp, lightly iridescent, peacock-blue, golden-bronze and magenta chalcocite crystals form an excellent, two-sided thumbnail specimen from the famous mid-1990s finds at the Flambeau Mine of Wisconsin. The large crystal is 1.8 cm and the piece has a nice sculptural aspect to it. Highly representative material from this famous locale, which is now extinct. The exact mine location is the Lucky Friday Pocket, 970 Level. Ex. Wes Parker Collection.
