A beautiful tanzanite crystal with high glassy luster, gemmy clarity, and sharp form. The majority of tanzanite crystals have been heat-treated, however this one is completely natural. The color ranges from a warm, golden tone at the base, to a rich purple on the top half. The purple area exhibits the characteristic strong pleochrosim, showing a color shift from a pleasing periwinkle-blue to a rich, royal violet.
