While not as popular as Emeralds or diamonds, the gorgeous blue of Tanzanite cabochons is rapidly becoming more popular.
It can be quite an expensive stone, but these pieces are at the budget end of pricing. Typically, this is due to a paler colouration and more inclusions.
Tanzanite is mined in one small area of Tanzania. It is rare, especially in higher grades. The lower grade pieces tend to be an almost cornflower blue – the higher grades are a violet blue.
