This is a very rich specimen of this uncommon copper-silver-arsenic sufide. Crystals such as these are rare, especially of this size. Specimens like this one were brought to the market by Dr. Jaroslav Hrysl 5 or 6 years ago maybe more. They hit the market then vanished. Virtually all of the silvery mineral in the photos is Pearceite. The crystals, in sub-parallel rosettes, span 6mm across and carry a brilliant luster.
