87.9% Light Return
Angles for R.I. = 1.54
41 facets + 12 facets on girdle = 53
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.351 T/L = 0.351
P/W = 0.443 C/W = 0.173
H/W = (P+C)/W+0.02 = 0.636
P/H = 0.697 C/H = 0.272 Vol./W^3 = 0.208
Addition # 6 - Cut this in refractive indexes 1.54 to 1.93 with no changes. I originally designed this for Garnets, it works well in saturated materials.
