Angles for R.I. = 1.54
53 facets + 8 facets on girdle = 61
8-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.330 T/L = 0.330
P/W = 0.466 C/W = 0.209
H/W = (P+C)/W+0.02 = 0.696
P/H = 0.670 C/H = 0.301
Vol./W^3 = 0.257
Addition # 6 - This works well in refractive indexes 1.54 to 1.93 with no changes. I prefer it in medium saturated material. It is for nice earrings and ring stones.
