Tanzanite

 

Colour Variations

 

 

 

 


Hardness

6-7 on the Mohs Scale

Toughness

Fair to poor, due to cleavage and sensitivity to thermal shock.

The first thing you notice is the color: Deep, vivid blue, with a purplish tinge that dances about the stone as it moves in the light. With its dazzling intensity and complex play of color, Tanzanite boasts a uniquely sensuous appeal.

Tanzanite’s dramatic discovery, coupled with its scintillating beauty, caused a worldwide sensation. To date, the world’s only source for the gem remains the hills of northern Tanzania, near Mount Kilimanjaro. They are heat treated to produce colours that include light to dark violetish blue and blueish purple, as well as pure blue.
