Near floater specimen of Dolomite crystals covered by small Pyrrhottite crystals serving as the matrix for a superb 4.2 cm Albite crystal. It's not often you see an Albite crystal so fine and featured as the main focal crystal of a specimen. Super for a Feldspar collector.

Razor sharp, lustrous, and transparent Spahlerite crystals to 1.8 cm pn Quartz matrix. The crystals are brown and green in color and of top quality, 5.5 x 5.5 x 2.5 cm.

Rare bi-color Tanzanite crystal with a yellow cap over a blue core. Another unusual feature of this crystal are aligned hair-like fibers of another mineral (Rutile?) that point inward and down from inside of the wide sides of the crystal (center photo). Natural, unheated gem Tanzanite crystal, 2.4 x 1 x 0.8 cm.

Glassy and lustrous gem blue/yellow Tanzanite crystal, even more glassy and transparent in person. Complete high quality crystal. Natural, unheated gem Tanzanite crystal with unusual coloration.

Glassy and lustrous gem Tanzanite crystal of excellent quality.  This is a trichroic crystal of purple and blue with a good red up the C-axis (see last photo). Complete all around and undamaged with good luster. Natural, unheated gem Tanzanite crystal weighing 50 carats.

Fine gem Tanzanite crystal with good transparency from top to bottom. Complete all around and undamaged, 2.2 x 1 x 0.8 cm.

Large cubic crystals of metallic grey Acanthite from Guanajuato, Mexico. A superb, complete and pristine thumbnail sized specimen from the John Barlow collection (Barlow specimen #3561).

Fine thumbnail acanthite with mulitple crystals culminating in a large, sharp 1.5cm cubic crystal at the tip. Better in person, 3.1 x 1.5 x 1.5 cm.

Clear Quartz crystal partially enclosing what was once a complete green Tourmaline crystal. The Tourmaline within the Quartz remains complete, however where it exits the Quartz (on top and along the backside), it has altered to a rectangular stack of Lepidolite crystals. Really neat and interesting specimen. As a collector you are always looking for unique pieces, and this one sure is!

Two exceptionally fine Anapaite crystals which formed in a 2.3cm wide fossil bivalve. The crystals are translucent to transparent with rich meium green color. These are now hard to find and the quality of the Anapaite is very high.

Fine, near floater specimen consisting of light purple Fluorite cubes, Arsenopyrite (in an interlocking 4cm cluster), pearlescent pink Dolomite that wraps all around the backside, and Muscovite. Highly aesthetic classic Yaogangxian combo.

Large, fine single Ferberite crystal. A very good example of a mineral that is somewhat common now, however will soon will be a classic, ranking as the worlds best, size 5.5 x 4.5 x 2 cm.
