Chalcocite ps. After Covellite w/ Pyrite & Quartz (ex Romero Coll.)

Item Description

An OUTSTANDING, OLD-TIME Butte combination and pseudomorph specimen from the famous Leonard Mine. The highlight of this very showy 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 combo material from the renowned locale and is from the famous Dr. Miguel Romero Collection formerly on display at the University of Arizona Science Center for the last 12 years until I bought it. Valued at $1000-1200 and well worth it
