Mohs Scale Examples
Tanzanite ranks between 6.5 and 7 on the Mohs hardness scale, which means it is a slightly soft gemstone. Tanzanite also exhibits perfect cleavage, which indicates the gem’s tendency to break from a strong blow. Tanzanite repairs are quite common in our workshop and we always advise setters to be extra careful when working with tanzanites.
