Notes - Blue-Blue is considered the top AAAA color. All AAAA blue-blue and top AAAA violet blue are heat treated using a very specific temperature and time which produces velvety Kashmir type color of the finest caliber. Unheated tanzanite is not the AAAA color range and just because you print it does not make it true. This is the finest Tanzanite known as Zoisite if unheated.
