L/W = 1.233 T/W = 0.462 T/L = 0.374
P/W = 0.396 C/W = 0.166
H/W = (P+C)/W+0.02 = 0.582
P/H = 0.681 C/H = 0.285

Addition # 8 - Cut this in refractive indexes 1.62 to 1.93 with no changes. This is fast and easy, good for a novice who wants to try a checker board. I like this in any medium color and it works best in a medium size stone.
