Tanzanite is a hydrous Calcium-Aluminum Silicate with a hardness of 6.5 on the Mohs scale.

It is not as hard as diamond which rates as 10 or sapphire which rates as 9 on the Mohs scale but harder than steel which rates about 4-5. Therefore Tanzanite should not be worn during activities that may cause impact. Ideally it is set as a necklace, dress ring, earrings or occasionally a bracelet.
