Yellow Fluorite from Moscona is fairly common, but this specimen is uncommonly good due to it's large size (19cm), transparency, 'wet' luster, and accents of white scalenohedral Calcite crystals along the top edge.

Fantastic old Copper specimen composed a tall central spinel-twinned crystal with smaller attached crystals. Complete all around and undamaged with good patina.

Sharp, water clear Quartz crystals included by Brookite crystals. The main Quartz crystal has both a large 2cm Brookite that rises up off the bottom plus a smaller approximately 8mm Brookite floating in the termination. Fine and undamaged, one of the better examples from this occurrence that I've seen.

Merelani Prehnite is considered by many, including me, to be the best in the world, and what has been produced in the last year or two has been the best. This beautiful specimen is a perfect example of this quality. Large translucent crystals with good yellow color in a somewhat flower-like rosette formation. It's undamaged and formed atop a (now gone) Tanzanite crystal and only tiny bits of Tanzanite remain on the base.

Red Hematite matrix with typical black Hematite crystals (both sides) and Quartz crystals (one side). What is uncommon is the presence of Fluorite crystals which occur as transparent cubes of about 3mm.

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 mineral collection. Large, showy eye-catching specimen.

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