An outstanding, old-time Butte combination and pseudomorph specimen from the Leonard Mine. The highlight of this fine piece is the top-left cluster of chalcocite after sharp covellite blades. The quartz plate matrix is stunningly and richly sprinkled with highly lustrous, striated, brass-yellow pyrite cuboctahedrons. This is classic combination material from the renowned locale and is from the Dr. Miguel Romero Collection formerly on display at the University of Arizona Science Center for the last 12 years.
