Ex. Roland and Kathy Sherman

Traded from Willard "Perky" Perkins collection in 1991, and dating back probably to the 1950s or 1960s, this is a superb chalcocite from the locale - where such robust crystals are very uncommon. Pristine save only one very teeny-tiny ding atop, and complete all around. This is a major thumb for the locale. It is one of my favorites in the collection. From the Roland and Kathy Sherman thumbnail collection: they are competitive thumbnail exhibitors from Southern California, specializing in copper species. Joe Budd Photos
