Gram Book 1 - It is all cut to center point and cuts easy. A larger size stone is better but it can be cut small. This works well in man-made Sapphire and CZ if you want to cut it large, but cannot find, or can afford, a large piece of natural rough. Cut in refractive index 1.73 to 2.14 (88.7%) with no changes.
