Bright, silvery crystals of Arseonpyrite with Quartz crystals. Showy Panasquiera classic in great condition.

Highly lustrous Quartz crystals with silvery/black Hematite crystals just under the surface of the Quartz crystals. Undamaged, with old collection numbers attached to the bottom.

Highly lustrous Azurite crystals, some partially psuedomorphed to Malachite. Besides the main coverage of crystals on top, there are also many vugs of crystals on the sides and bottom. Undamaged old specimen, with old collection number attached to the bottom.

Double-terminated twinned Calcite crystal intergrown with highly lustrous Galena crystals all atop Sphalerite. There are some cleavage faces on one termination of the Calcite, but also nice pointed ends that make it not as noticable. The Galena cubes reach 2cm in size and the combination makes for an attractive specimen good when viewed from any angle.

Sharp, water clear Quartz crystals included by Brookite crystals. The main Quartz crystal is double-terminated. The Brookite crystals have fine hair-like needles of Rutile extending off the crystal surfaces. Fine and undamaged, one of the better examples from this occurrence that I've seen.

Lustrous metallic Arseonpyrite crystals with large Quartz crystals. This would be a great addition to a Yaogangxian or Chinese collection. Large, showy specimen.

Large translucent yellow Prehnite crystals with attached blue/grey Chabazite crystals. 

Water clear Dolomite crystal with included and attached silvery blades of Hematite. The Brumado mine is best known for Uvite and Magnesite but also produces other really interesting pieces such as pink Topaz, Emeralds, and superb Dolomite. The large Dolomite is twinned and tabular, with the smaller crytals at the base a mixture of both untwinned rhombs and tabular twins. Showy and lustrous, complete all around. The right side is smooth and lustrous but appears to be a cleavage face. Comes mounted on a Lucite stand. Unusual, aesthetic specimen!

Smokey Quartz gwindel with a well pronounced curve and very smooth, lustrous faces. Transparent with little to no internal cracks or veils. Undamaged with much better glassy luster than the photos indicate.
