A very beautiful unheated tanzanite with a very slight bicolour effect of violetish blue.
Tanzanite is almost always heated to remove other shades of colours, but lately there is a growing trend to appreciate the different colours along different axes of the gem.
This one is very elegant in the octagon cut.
