L/W = 1.000 T/W = 0.507 T/L = 0.507
P/W = 0.485 C/W = 0.179
H/W = (P+C)/W+0.02 = 0.684
P/H = 0.709 C/H = 0.262
Vol./W^3 = 0.256
Addition # 5 - This is very nice and it is designed to work in even a very small size stone. This is killer in any R.I. with no changes, including Quartz. I like it in Sapphire and use this design a lot. It cuts very fast and is really a "Money Cut"…
