Prehnite (excellent crystallization) with Tanzanite

Item Description

The blue/purple namesake varietal of Zoisite from Tanzania is called Tanzanite, and it is likely the most popular mineral/gem to come from the entire country. 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 gemmy crystals of a beautiful color. This piece features a group beautiful, sharp, distinct, lustrous, rather gemmy, greenish yellow to blue-green crystals of Prehnite measuring up to 1.6 cm, free of matrix. The key aspect of the specimen is a small amount of purplish Tanzanite on the reverse side. The Prehnite group is in good shape, though the bottom has a saw mark, which does allow the piece to sit nicely on its own. . This recent find (2019) of has really made an impression on us because they are some of the finest quality crystallized Prehnites that I have encountered in a long time, and the associated Tanzanite takes it over the top. Valued at $1,000.
