Diopside on Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz121a.jpg] Diopside on Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz121b.jpg] Diopside on Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz121c.jpg] Diopside on Graphite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz121d.jpg]

Vivid green Diopside crystals on crystallized Graphite. Individual Graphite crystals reach about 5-6mm. These Diopside on Graphite crystals are exceptional specimens only seen previously from the December 2007 pocket of the Karo Pit - it is possible that this one is also from that find but has only now made its way to market.


TZ122 - Tsavorite with Diopside $ 600 SOLD
Merelani Hills, Arusha, Tanzania
thumbnail - 2 x 2 x 1.4 cm

Fine thumbnail specimen of pale green to white Diopside crystal with an attached Tsavorite. The Diopside has a stepped termination and great luster and a color unlike any I've ever seen from Merelani. The Tsavorite has the top green color. Fine and unusual, if your looking for a special thumbnail this is it.


TZ123 - Tanzanite $ 3500 SOLD

Exquisite gem crystal, undamaged and unheated with great luster and transparency. Superb quality here, and a real winner of a specimen. 55 carats of nearly 100% facet grade Tanzanite. Great crystal.

Magnesio-axinite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz126a.jpg] Magnesio-axinite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz126b.jpg]

miniature - 4 x 1.5 x 0.4 cm


Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz127a.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz127b.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz127c.jpg]

Etched Tanzanite crystal with a flattened, tabular form. Etched Tanzanites are not common and this one has such an unususal shape, reminds me of Halloween for some reason. Natural, unheated, and undamaged.


TZ129 - Tanzanite $ 4200
Merelani Hills, Arusha, Tanzania
miniature - 4.5 x 2 x 1.3 cm

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.

TZ132 - Tanzanite with Diopside $ 350 SOLD
Merelani Hills, Arusha, Tanzania
thumbnail - 2.5 x 1.9 x 1.8 cm


Tanzanite with Diopside from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz132a.jpg] Tanzanite with Diopside from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz132b.jpg] Tanzanite with Diopside from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz132c.jpg]

TZ133 - Tsavorite $ 2400 SOLD
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.


TZ134 - Grossular $ 400 SOLD
Merelani Hills, Arusha, Tanzania
thumbnail - 0.6 x 0.6 x 0.6 cm


Grossular from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz134a.jpg] Grossular from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz134b.jpg] Grossular from Merelani Hills, Arusha, Tanzania [db_pics/pics/tz134c.jpg]

Rare yellow Grossular - the only one I've ever seen from Merelani. A complete and glassy crystal that is totally transparent. There are a couple tiny chips on adjacent corners, otherwise perfect.


TZ135 - Tanzanite $ 900
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.


TZ136 - Chabazite on Prehnite $ 450 SOLD
Merelani Hills, Arusha, Tanzania
miniature - 3.2 x 2 x 2 cm

Translucent yellow Prehnite sprinkled with small brown crystals of Chabazite. This is the finest quality yellow Prehnite specimen I've seen from Merelani. A bit of Tanzanite attached to the bottom too.
