89.8% Light Return
Angles for R.I. = 1.54
67 facets + 18 facets on girdle = 85
2-fold, mirror-image symmetry
96 index
L/W = 1.325 T/W = 0.353 T/L = 0.266
P/W = 0.556 C/W = 0.231
H/W = (P+C)/W+0.02 = 0.807
P/H = 0.689 C/H = 0.286
Vol./W^3 = 0.373

Addition # 8 - This can be a little tough to cut, but not too hard. It works in refractive indexes 1.54 to 1.93 with no changes. This works well in medium to dark material, I like it in Garnets. A L/W=1.325 preform is a good idea.
