87.1% Light Return
Angles for R.I. = 1.54
69 facets + 8 facets on girdle = 77
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.246 T/L = 0.246
P/W = 0.494 C/W = 0.213
H/W = (P+C)/W+0.02 = 0.727
P/H = 0.679 C/H = 0.293
Vol./W^3 = 0.340

Addition # 8 – This is fun to cut and not as hard as it may look. It works well in about any material. Cut this in refractive indexes 1.54 to 2.14 with no changes. I like this in medium to light colored materials.
