A sculptural, old-time, cabinet copper specimen from the Ajo Mine and the Brent Lockhart Collection. Weighs 542 grams or 1.2 pounds. This showy piece is composed solidly of sharply crystallized, tetrahexahedral copper crystals with a very nice, variable patina. This excellent piece is reinforced with glue in the back to help support its mass. A highly representative and large example of the species and famous mine.
