L/W = 1.000 T/W = 0.418 T/L = 0.418 P/W = 0.632
C/W = 0.231 H/W = (P+C)/W+0.02 = 0.883 P/H = 0.716 C/H = 0.261 Vol./W^3 = 0.443

Addition # 12 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is designed to be a large stone and it works well in light to medium saturations. This is not hard to cut but does takes some experience. I like it in Aquamarine.
