This is a nice Topaz as you can see. Lots of facets, which give it great brilliance. But a bit of a window on this stone.

I   took pictures of this stone in high magnification against a   white background to give   you the best idea of color and quality.  As a certified gemologist I can verify that the above description is     accurate and that this stone/stones have been tested in the gem lab to   verify   identity and natural origin.

Virtually 100% of the Blue Topaz on the market has been heated and irradiated to achieve its color. The practice is considered both safe and acceptable by the gemstone community. But you need to be very careful where you buy Blue Topaz from. There are safety precautions and waiting periods that need to be done to make sure the radiation process was correctly done, and that all traces of radiation are now gone. That’s why you should only really buy Blue Topaz from reputable sellers, to keep yourself 100% safe. In addition to that, there is quite a bit of imitation Topaz on the open market these days, synthetic blue Quartz that looks very close to high quality Blue Topaz. So be careful where you buy.
