Color zoning in this Tanzanite crystal is clearly visible, with a vibrant section of saturated violet-blue near the termination, transitioning into silvery-lavender and near-colorless zones below. Natural etching and vertical striations accent the prism faces, and the overall form shows a well-developed crystal habit typical of Tanzanite from Merelani Hills, Tanzania.
Tanzanite is pleochroic, displaying different colors from different angles—this crystal shows that effect clearly, especially in its unheated state
