Tanzanite Tanzanite Tanzanite Tanzanite

Old time multi colored Tanzanite crystal. These green crystals are very rare and came out only years ago, this crystal being at least a dozen years old. It's so colorful it looks like a piece of candy with blues, greens, and pinks showing as you turn it in your hand. It's not perfect, with some of the base missing and contacting on the backside, but a real unusual and hard to find piece for a Tanzanite collector.

Diopside on Tanzanite Diopside on Tanzanite Diopside on Tanzanite

Wow, rare combination specimen of a double terminated lime green Diopside wedged right in the termination of a Tanzanite crystal. A portion of the termination is missing as can be seen in the photos, but the position of the Diopside, plus the additional Diopside crystals and Graphite at the base make this a striking specimen. Valued at $350.
