The difference between Tanzanite heat treatment and natural stone
So the conclusion is that: formed by natural phenomena in the heat treatment of Tanzania is natural stone; by artificial heating stroke Tanzania is not natural. 99% of the market is now artificially heat treatment. If anyone says he is not Tanzanite after heat treatment, it must be a lie.
But there are two kinds of heat treatment, heat treatment is a natural, such as thunder fire, but the Tanzania has exist theoretically, the surface can be found on the Tanzania had been dug up, only exist in theory. Another heat treatment is artificial, after high temperature heating, such a good color tanzania.
Tanzanite stone color is light grey and blue, see no heat-treated Tanzanite color is not in the traditional sense of tanzania.
