Pyrite on Tanzanite

Wow! Trichroic, double terminated Tanzanite, and if that was not good enough, bright Pyrite crystals to 4mm provide added appeal. There are also large gem zones within. Color is purple on the main display face, blue when viewed from the side, and purplish red when you shine a light up the C-axis. One ding on the side of the small side crystal, otherwise perfect all around and double terminated. Illustrated in the Sept.-Oct. 2009 issue of the Mineralogical Record (Figure 78, page 383). Natural, unheated gem Tanzanite crystal, 3.1 x 1.7 x 1.1 cm.
