Thick cluster of curved blue Prehnite crystals. A little bit rough around the edges but the best specimen of the few I saw available with a nice formation of thick curving crystals rather than the single tabular crystals.The color of the blue intensifies in natural sunlight and gets very deeply colored in the thicker parts.

Sculptural Quartz crystal on Tanzanite. Rarely seen Quartz crystal from Merelani on a terminated Tanzanite crystal. The Quartz is 4cm tall with complex form and sharply pointed termination. A small flake of Tanzanite at the base of the Quartz came off while I was cleaning it and I have reattached it.

Merelani Hills, Arusha, Tanzania
small cabinet - 5.2 x 3.5 x 2 cm


Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz130a.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz130b.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz130c.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz130d.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz130e.jpg]

Tanzanite crystal cluster with a 5cm tall central crystal and 4cm tall crystal attached to the back and smaller crystals at the base. Natural, unheated, and undamaged. The white spot seen on the face of the main crystal is a crystal of Prehnite and is not damage.


TZ131 - Diopside with Graphite $ 200 (=~ £ 129)
Merelani Hills, Arusha, Tanzania
thumbnail - 2.5 x 1.1 x 0.6 cm


Diopside with Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz131a.jpg] Diopside with Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz131b.jpg] Diopside with Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz131c.jpg]

Sharply formed crystal with good luster and highly transparent. With attached Graphite on backside. More transparent than typical Diopsides from here.


TZ133 - Tsavorite $ 2400 (=~ £ 1545)
Merelani Hills, Arusha, Tanzania
thumbnail - 1.2 x 0.9 x 0.9 cm


Tsavorite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz133a.jpg] Tsavorite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz133b.jpg] Tsavorite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz133c.jpg] Tsavorite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz133d.jpg]

This is a rare nearly perfect and complete Tsavorite crystal. Tsavorite typically form on graphite and almost always have a contact on the bottom where they were attached to the Graphite. This one grew atop the thin edges of Graphite crystals. Although there are some dark colored grooves on the bottom surface caused by the Graphite crystals, it is fully crystallized all around. Under a loupe I found a couple tiny nicks on the bottom, otherwise it is undamaged and of exceptional quality, and it has great color.


TZ135 - Tanzanite $ 900 (=~ £ 579)
Merelani Hills, Arusha, Tanzania
miniature - 3.5 x 1.2 x 1.1 cm


Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz135a.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz135b.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz135c.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz135d.jpg]

Fine quality Tanzanite crystal that is complete all around with good gem zones. Trichroic with blue and purple coloration from the sides and a good red color up the C-axis. Natural, unheated, and with hardly any damage (just a couple very tiny edge nicks). A good value for the price. I backlit one photo for fun.
