L/W = 1.000 P/W = 0.435 C/W = 0.219H/W = (P+C)/W+0.02 = 0.674
P/H = 0.645 C/H = 0.325

Addition # 9 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is fun to cut and has a pretty whirl pattern in almost any light. I like it in light to medium saturated materials. A table can be cut on large stones.
