Like the pink variety thulite, it is used exclusively as a gemstone. As with zoisite, Tanzanite crystallizes in the orthorhombic crystal system and typically develops transparent, prismatic to columnar crystals that can reach several centimeters in length and exhibit a glassy luster on their surfaces. The cleavage surfaces, by contrast, shimmer more nacreous. Shipping as insured registered mail
