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!

Blue and purple Fluorite from the famous Minerva Mine. There is a purple core with outer zones of various shades of blue. This is the color that is hard to find and that everyone wants. Nice and gemmy and nearly pristine with just a cleave at one corner.

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.

Large and especially fine quality Clinoatacamite crystals with white Calcite over a layer of Malachite. These are regarded as the world's best Clinoatacamite specimens, and this is a good one. The crystals are all pristine. They were protected by a layer of Selenite that I dissolved away, leaving these perfect crystals. Individual crystals reach 1.3cm wide. The Lily Mine is now closed.

Glassy green Tsavorite crystals on Graphite. The largest Tsavorite is 9mm wide and undamaged.
