(click on an image to enlarge)

Single Diopside crystal with SUPERB deep vivid green color, the best color for Diopside, similar to the color of the specimens from the December 2007 pocket (and this in all likelyhood is from that pocket). In addition tot he great color, it has much better transparency than most of this coloration. Complete all around with unusual modified termination faces.

TU96 - Epidote sold

Mt. Moudi, Arusha, Tanzania
Thumbnail - 3 x 1.5 x 0.6 cm

(click on an image to enlarge)

Single Epidote crystal of deep green color, translucent along the edges. This came in a parcel of Tanzanite, though I doubt it it is from Merelani , and for that matter may not even be from Tanzania as there is a known Epidote deposit in Kenya.Good well formed crystal complete all around.

TU98 - Prehnite 0n Tsavorite sold

Merelani Hills, Lelatema Mountains, Arusha Region, Tanzania
Thumbnail - 1.8 x 1.5 x 1.1 cm

(click on an image to enlarge)

Gemmy, vivid green Tsavorite crystal with an attached 1.1cm yellow Prehnite crystal. The Tsavorite has glassy luster and is etched. The Prehnite occurs as a well developed single crystal. I have never seen this association so before, though these yellow Prehnites are sometimes seen on Tanzanite crystals from the same mine. Though etched, the Tsavorite has internal gem areas and the gem dealer I bought this from had it priced in the mid-four figures, likely due to the gem rough value.
