81.8% Light Return
Angles for R.I. = 1.54
52 facets + 12 facets on girdle = 64
3-fold, mirror-image symmetry
96 index
L/W = 1.023 T/W = 0.503 T/L = 0.492
P/W = 0.508 C/W = 0.188
H/W = (P+C)/W+0.02 = 0.716
P/H = 0.709 C/H = 0.263
Vol./W^3 = 0.258

Addition # 5 – This is very nice and works especially well in light colored materials. It can be cut in R.I. 1.54 to 1.93 (81.9%) with no changes.
