A 4.5 cm white Scheelite crystal that is partially coated by Lollingite and also partially etched. A metallic silver-colored mineral (looks like Molybdenite) can be seen in the tip that formed as an epimorph of the Scheelite and was later covered by another layer of Scheelite. Unusual and interesting piece from recent finds in Inner Mongolia.

Highly transparent single Aquamarine crystal from Vietnam.  The crystal has high glassy luster and is undamaged.

Fan-shaped cluster of purple Huelandite and bow-tie Silbite on a Quartz over Basalt matrix. The purple color is uncommon and the overall appearance is very good, and it's undamaged.

Golden yellow rhombs of Smithsonite to 1.2cm wide.

Superb matrix specimen with two complete clusters of translucent Olmiite. This is a specimen I bought many years ago from Clive Quiet from the original find. Perfect and undamaged Olmiite clusters that look like a pair of gumdrops.

Glassy and gemmy single Tanzanite crystal with an elongated, unusual form. It's somewhat triangular in cross-section, natural and unheated. Fine and undamaged and a good value for this size and quality.

Translucent red/orange color pagoda-shaped crystal of Wurtzite. At the tips are dark areas of epitaxial Sphalerite. These recent Wurtzite specimens from the Merelani Tanzanite mines are the world's best and now rarely found.

Aesthetic combo specimen from the N'Chwanning Mine with Hausmanite, Ettringite, and Andradite. Fine quality Hausmanite (sharply formed with very bright, satiny luster) with an attached pale yellow Ettringite crystal all on red Andradite.  For what is sometimes called a 'black ugly' mineral, this one is quite colorful!

Blue Prehnite specimen about as good as these get form wise as most of these are massess of crystals with at least some damage around the edges. This is a clean group front and back, nearly a floater with some traces of Graphite on the bottom where it was attached. These have a nice color change between shades of blue in different lighting.

1.4cm crystal of Ludlamite on matrix with Siderite. Aesthtics and quality are superb, undamaged.
