I tried several times to get this bad boy. Finally got it and at a great price. This is a Cats Eye Tourmaline in a khaki green color. Has a nice cats eye when a good light source is on it. This does have some inclusions, which is not uncommon for tourmaline, but a nice translucency to it. The top half has been polished and the bottom is still unpolished probably since this will more then likely go in a bezel setting and would not be seen anyway. This would make a fabulous mens ring! The gemstone is almost a perfect 16 x 12 mm oval and is just shy of 16.5 carats.
