Glassy, transparent Quartz crystal, coated on one half with fine mica crystals, with attached green Fluorite. Undamaged and good all around.

Purple Fluorite cubes to 3cm on edge intergrown with Arsenopyrite and Muscovite crystals, all atop a Quartz crystal. Good all around and undamaged.

Water clear light green Fluorite cubes on matrix. Central main isolated cube is 2cm on the diagonal. Some of the smaller crystals are so clear you can't see them until you reflect light off their faces. This is the best quality from this find that I could find. Complete all around and undamaged. Better than photos.

Transparent purple/blue Fluorite cubes on a Quartz crystal covered matrix. Exceptionally bright crystals! It really pops when compared to others. Glossy, wet-looking luster. There are a couple tiny, trivial nicks that you have to search for, otherwise undamaged. This one is really nice and way better than photos.

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.
