Addition # 10 - Note: The corners on this design float. Cut them in to look right. You can vary the blades by changing the corner size. This is very nice in light to medium saturated materials and is again great for earrings. A table is not needed for small stones. Cut in refractive indexes 1.62 to 1.76 with no changes.
