Addition # 9 – Cut in Refractive indexes 1.54 to 1.93 with no changes. This is designed for clean medium to light colored Amethyst and Citrine which is readily available and a mainstay for jewelers. Try it for earrings, the flash is quite nice and it’s an easy and fast cut. No table needed on a small stone, although I usually put a table on all I cut unless the stone is very small.
