This is an old spcimen out of the Bruce Murphy collection, who collected at the mine back in the 1970s good on both sides. The specimen is composed of dense, transluscent Chrysocolla with a botryoidal surface of dark blue (heterogenite?) and lighter green. Good on both sides.

Large, chunky Hematite crystal with an uncommon psuedocubic form. Great luster with parallel surface striations. This is an old specimen from a collection dating back to the 60s and 70s. It came without precise locality information, but I suspect it is from the Casa de Pedra mine in Congonhas, Minas Gerais. It's complete all around with some indentations from other crystals on top near the back, but remarkably pristine with only a couple small nicks. Even the bottom is rehealed. Weighs 2 pounds and 14 ounces!

Classic Tsumeb specimen of Dioptase on white Calcite. Super lustrous, transluscent Dioptase crystals in small clusters and isolated crystals. There is damage to a couple crystals, but the vast majority are fine and undamaged. Despite the damage, this quality is rare to find now.

Two interpenetrating transparent Fluorite cubes with rich purple color. In great condition with good luster. Main crystal is 6.2cm on the diagonal.
