80.9% Light Return
Angles for R.I. = 1.54
53 facets + 8 facets on girdle = 61
8-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.206 T/L = 0.206
P/W = 0.445 C/W = 0.231
H/W = (P+C)/W+0.02 = 0.696
P/H = 0.640 C/H = 0.331
Vol./W^3 = 0.254
Addition # 6 - Cut in refractive indexes 1.54 to 1.93 (85.5%) with no changes. This is fun and fast to cut. It works well in any material, although I prefer it in light colors.
