Item Description

The mining around Merelani Hills in Tanzania has produced a good number of superb specimens and gems of Tanzanite over the past 50+ years. While this area may be synonymous with Tanzanite, there are many other interesting and fine quality minerals found there, including some of the most attractive Prehnites from any world locality. Recently some truly remarkable Prehnites were found that are not only fine quality, but feature superb, large, gemmy crystals of a beautiful color. This piece is composed of beautiful, large, sharp, distinct, lustrous, GEM QUALITY, greenish yellow crystals of Prehnite with no matrix. The key aspect of the specimen is on the reverse side, you can see a thin layer of vibrant blue-purple Tanzanite. The Prehnite group is in good shape, though the outer edges are incomplete where the piece was separated from the pocket wall. This recent find (2019) of has really made an impression on me because they are some of the finest quality crystallized Prehnites that I have encountered in a long time, especially with larger than average crystals which have distinct separation between them, they're not just a tightly intergrown mass. The associated Tanzanite takes it over the top, and makes this a very desirable, fine quality and colorful example of a mineral that you don't commonly think of when it comes to this part of the world. Valued at $4,000.
