Like the pink variety thulite, it is used exclusively as a gemstone. As zoisite crystallizes, tanzanite forms in the orthorhombic crystal system and typically develops transparent, prism-like to columnar crystals that can reach several centimeters in length and exhibit a glassy sheen on their surfaces. The cleavage planes, by contrast, are more nacreous. Shipping as insured registered mail.
