1. Definition and Properties of Tanzanite Stone

Tanzanite is a stone belonging to the zoisite mineral group and has a blue-violet hue due to its vanadium content.

• Crystal System: Tanzanite has an orthorhombic crystal system. It is usually found in the form of prismatic crystals and is cut like diamonds in jewelry making.
