A wonderful combo of Pyrite, some of which is irridescent, on Quartz on a massive Enargite matrix with well defined crystals to 2cm. 3 distinct collection labels on the bottom, the last of which was Chester Lemansky. Classic material. Heavy piece so expect postage to be on the high side. Locality: Leonard Mine, Butte, Silver Bow County, Montana Composition: copper arsenic sulfide
