Addition # 2 - This is nice in Electric Blue Topaz too. It cuts easy in a larger stone, and is good in any color, 1-16cts. I sell a lot of this shape in Tourmaline earrings. It is an interesting shape, different than a round or square, but still easy to set. Cut in refractive indexes 1.54 to 1.93 (87.4%) with no changes.
