82.5% Light Return
Angles for R.I. = 1.62
45 facets + 6 facets on girdle = 51
6-fold, mirror-image symmetry
96 index
L/W = 1.155 T/W = 0.980 T/L = 0.849
P/W = 0.528 C/W = 0.148
H/W = (P+C)/W+0.02 = 0.696
P/H = 0.759 C/H = 0.212
Vol./W^3 = 0.278

Addition # 8 - Cut in refractive indexes 1.62 to 2.14 with no changes. This one is a little tough to cut and will take some adjusting on the crown depending on the machine and, of course, the cutter. This is nice in about material, but I like it in light to medium saturated material.
