88% Light Return
Angles for R.I. = 1.64
85 facets + 12 facets on girdle = 97
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.591 T/L = 0.591
P/W = 0.439 C/W = 0.186
H/W = (P+C)/W+0.02 = 0.645
P/H = 0.680 C/H = 0.289
Vol./W^3 = 0.279

Addition # 2 - This works well in Peridot, Garnet, Sapphire, and Spinel. Cut it in a larger stone, I like peridot. The steps can change a little without much trouble, 1-24cts. Cut in refractive indexes 1.64 to 1.93 (88.7%) with no changes.
