Killer Tanzanite thumbnail that's also a great association piece too.  Fine, gemmy blue Tanzanite crystal with excellent luster and great transparency with attached large, single Prehnite crystals (analyzed) on the backside. Prehnite from Merelani is usually seen as rounded aggregates, yet on this specimen they occur as individual crystals to 7mm wide. In addition to the Prehnite, there are white crystals of an unidentified mineral also attached to the backside. A very nice Tanzanite, undamaged with TOP luster, good color and highly gemmy.

Single Tanzanite crystal with a Pyrite crystal attached to one side of the crystal. Pyrite is not unusual from Merelani, but Tanzanite specimens with attached pyrite are uncommon, especially those with the pyrite perched so aesthetically on the Tanzanite. The Tanzanite is also a bi-color with a yellow termination over a blue body color. Unusual addition to a Merelani suite.

AF763 - Tanzanite $ 4500
Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania
thumbnail - 3.1 x 1.8 x 0.8 cm


Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af763a.jpg] Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af763b.jpg] Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af763c.jpg] Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af763d.jpg]

Glassy bi-color crystal, blue base with a yellow termination. This crystal has superb luster and unusually uniform shape, retaining an even 8mm thickness all the way from the base to the termination. The yellow zone is facet grade and the blue zone, while having some internal fractures, is still mostly transparent - you can read through most of the crystal. Just a few tiny, trivial nicks otherwise totally undamaged. This is one of, if not the best of these yellow/blue bi-color crystals I have ever seen.


AF912 - Tanzanite $ 4200
Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania
miniature - 4.3 x 2.3 x 1.4 cm

Outstanding bi-color crystal, one of the best of this type I have seen. I have been watching these yellow/blue bi-colors as they have been being found over the past few years and this one would rank as the largest high quality crystal, and one of the top 4 overall. Luster is superb - very glassy. The top 1cm is flawless gem quality and would cut a significant gemstone. Undamaged, with a backside that slopes up to a partial crystal embedded in the backs. Weighs 24.6 grams.
