H/W = (P+C)/W+0.02 = 0.805
P/H = 0.762 C/H = 0.213

Addition # 4 - This is designed to be used in sets, it cuts pretty easy and has a nice flash. It works well around a square or trillion. Cut in about any material, I prefer medium color, 1/2ct and up. This works in Topaz… Cut this in R.I. 1.62 to 2.14 without changes.
