21.26ct Precision Cut Blue Topaz
This HUGE Blue Topaz is absolutely breathtaking! It's deep blue color is enhanced by irradiation (a common Blue Topaz treatment) and is precision cut, which gives the stones extra brilliance and appeal. Precision cut gemstones are cut by a computer that cuts the raw stone at their correct refractive index. This brilliance isn't able to be achieved by rudimentary native cutting methods, which is how most stones are cut.
