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!

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

Snow-white Barite blades, with some amber colored, over a matrix coated by drusy Sphalerite.This is out of an old collection built in the 60s and 70s and no further locality information was available. Clean and undamaged, good from both sides.
