Item Description

This new find of greenish yellow Prehnites 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. The combination of rich vibrant color along with wonderfully gemmy lustrous crystallization puts them in the upper ranks for quality of any Prehnite specimens around. These specimens are from the same mines that produce the world famous gem Tanzanite crystals in Tanzania. This piece is one of the few matrix Prehnites that I've seen from this locality featuring beautiful, lustrous, gemmy, greenish yellow "clamshell"-shaped crystals forming a spherical crystal aggregate aesthetically sitting atop a gemmy colorless Quartz crystal fragment. The Prehnite itself is virtually undamaged and the color is actually more vibrant in person than the photos might indicate. The piece could easily be trimmed down to create a "box buster" thumbnail. Valued at $450.
