“This is a nice specimen of galena, chalcopyrite, pyrite, dolomite and quartz from Brushy Creek Mine in Reynolds County, Missouri. One large 25mm octahedral galena crystal sits on gray dolomite. Iridescent chalcopyrite crystals are blue and green colored. Some brassy colored pyrite and colorless “drusy” quartz are scattered all over the specimen. It was collected in the 1980s. ”
