Like the pink variety thulite, it is used exclusively as a gemstone. As with zoisite, Tanzanite crystallizes in the orthorhombic crystal system and typically forms transparent, prism-like to columnar crystals that can reach several centimeters in length and show a glassy luster on the surfaces. Cleavage planes, by contrast, shimmer more pearly. Shipping as insured registered mail
