76% Light Return
Angles for R.I. = 1.54
55 facets + 6 facets on girdle = 61
6-fold, mirror-image symmetry
96 index
L/W = 1.155 T/W = 0.566 T/L = 0.490
P/W = 0.501 C/W = 0.243
H/W = (P+C)/W+0.02 = 0.764
P/H = 0.655 C/H = 0.319
Vol./W^3 = 0.306

Addition # 3 - This is straight forward to cut. I like to leave the P3 facets frosted for a nice different look. Any good material, 1/2-12cts. Cut in refractive indexes 1.54 to 2.14 (88.1%) with no changes.
