Prehnite from Merelani

26 specimens from new find of yellow Prehnite at Merelani Hills, Tanzania. A find of similar yellow Prehnite was made in 2006 and were sold at the 2007 Tucson show. I have not seen any new crystals since then, until now. These occur as wonderfully translucent clusters of crystals, many in spherical clusters and many with other associated minerals. I have backlit some of the photos to highlight their great translucency. Please note that due to their yellow color and translucency, tiny bits of Graphite stand out in the photos much more so than when you see the Prehnites in person.

Spherical cluster of glassy yellow Prehnite with big individual crystals. The cluster is intergrown with other minerals in a few areas, but the quality of Prehnite is excellent, highly translucent with light easily penetrating to the core of the cluster.

Gemm yellow Prehnite from the Tanzanite mines.  These bright lemon yellow Prehnites from recent finds are one of the best, if not the best, Prehnites in the world.

Small but very fine Prehnite cluster, nearly a floater on just the tiniest bit of Graphite matrix. The Prehnite is so clear you could cut a faceted gem from the middle of the main crystal.


AF278 - Prehnite with Tanzanite $ 130 SOLD
Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania
thumbnail - 3.7 x 2 x 1.5 cm

Colorful combo of blue Tanzanite with the lemon yellow Prehnite with a small amount of Graphite on back. While many of these specimens have shards of Tanzanite, this is the only one with a big partial crystal in a good display location. Good sparkling crystals all over, including the backside.


AF279 - Prehnite on Tanzanite SOLD
Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania
thumbnail - 2.7 x 2.4 x 2 cm


Prehnite on Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af279a.jpg] Prehnite on Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af279b.jpg] Prehnite on Tanzanite from Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania [db_pics/pics/af279c.jpg]

Spherical cluster of fine, glassy yellow Prehnite on a shard of Tanzanite. There even some Tanzanite shooting through the top of the cluster and a small amount of Graphite on one side. The quality of the prehnite is superb with big crystals extending out of the main cluster, good luster and very translucent. Because the crystals are so translucent, the little flecks of Graphite stand out alot more in the photos - I hardly notice them when holding the specimen in hand, I would say this one is much better in hand than the photos.
