An exceedingly fine Magnesioaxinite crystal with top glassy luster, good purple/blue color, and very gemmy. Many people don't know that these crystals exhibit a strong color change from purple to blue. This crystal also has more thickness than most.

Hard to find complete, floater crystal of Tsavorite - the only one out of the few hundred crystals I recently searched through from the new find. Glassy luster and good transparency, with some inclusions of Graphite. Undamaged.

TZ146 - Prehnite $270 available

Merelani Hills, Arusha Region, Tanzania
Miniature - 3.2 x 3.0 x 1.5 cm

Blue Prehnite in a fantastic, flower-like formation. A complete floater with minor amounts of attached Graphite. Translucent blue with a really nice formation, way better than most from the find which were mostly irregular massess of crystals with damage along the edges.

Miniature - 3.7 x 2.8 x 2.2 cm

Large single Diopside crystal, complete all around with good luster. Though light in color, it is uncommonly large and of good quality, with just a couple very tiny nicks.

TZ150 - Prehnite over Tanzanite sold

Merelani Hills, Arusha Region, Tanzania
Thumbnail - 3.0 x 2.5 x 2.0 cm

Unusual specimen of blue Prehnite that has overgrown Tanzanite. The Prehnite is in a stunning formation with a broad chisel termination, and the color contrast between the light blue Prehnite and dark blue Tanzanite is striking.

Translucent blue Prehnite crystal that grew atop Tanzanite.

TZ154 - Tanzanite sold

Merelani Hills, Arusha Region, Tanzania
Thumbnail - 2.7 x 1.0 x 1.0 cm

(click on an image to enlarge)

Fancy colored Tanzanite crystal with a pink coloration in one direction, yellow in the other, and a peachy color up the C-axis. There is a cleavage on the back face, otherwise this is in good condition, but despite the minor damage, this is in way better condition than most of the fancy colored Tanzanites I've seen. A very unusual coloration.

Thumbnail - 1.6 x 0.7 x 0.6 cm

Highly saturated green Diopside crystal. Complete and undamaged. From the December 2007 pockete with the top green color.
