Angles for R.I. = 1.62
105 facets + 8 facets on girdle = 113
8-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.509 T/L = 0.509
P/W = 0.465 C/W = 0.204
H/W = (P+C)/W+0.02 = 0.689
P/H = 0.674 C/H = 0.297
Vol./W^3 = 0.262

Addition # 1 - This design cuts easy, however it should be a larger stone. Watch the meets on P4 so that the P5, P6 look even, 2-12cts. Cut in refractive indexes 1.62 to 1.93 (90.6%) with no changes. I prefer this in light to medium colored materials.
