I have a number of standard round brilliants that were cut from a lot of Afghanistan material I purchased years ago. I could see a touch of blue in part of the lot, that use to be half of a bicolor (pink was the other sides color), but feel apart. In some of the finished rounds I see a touch of blue and in others I do not. The posted gemstone is one of the larger and cleaner (eye clean) ones that I am sure is a pure Achroite (colorless) under reasonable light. It has the typical bright crisp look of Afghanistan tourmaline and weighs 1.08 carats.
