Stunning Round Fancy Cut Swiz Blue Topaz 9.5CT, Flawless, Clean IF gem. Dots you see on the pics are dust. Gemstone is clean and beautiful. It sparkles and stands out. If your birthstone (or someone you love) is Topaz, this is a nice one to get.
Treatment: Irradiation (Almost all blue Topaz sold must go thru some form of heating for its color. It has no impact of its quality or prize). If someone sells you 100% unheated Blue Topaz, I would test it for irradiation. So technically many sellers can claim color Topaz unheated. Even though we have no evidence this stone went thru irradiation process, we include this info for general information.
