L/W = 1.000 T/W = 0.259 T/L = 0.259
P/W = 0.435 C/W = 0.177
H/W = (P+C)/W+0.02 = 0.632
P/H = 0.688 C/H = 0.280
Vol./W^3 = 0.213
Addition # 9 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is easy to cut and I designed it for medium saturated stones. This works well in Garnets like Rhodolite and it's killer in light colored Amethyst for earrings.
