L/W = 1.000 P/W = 0.435 C/W = 0.276
H/W = (P+C)/W+0.02 = 0.731 P/H = 0.595 C/H = 0.378

Addition # 10 – Cut in refractive indexes 1.62 to 2.14 with no changes This design is another one of my flower effects, it is really nice. Cut it in light saturated stones for best reflections. It is fast and easy. C3 is a step and can vary.
