Angles for R.I. = 1.62
52 facets + 6 facets on girdle = 58
3-fold, mirror-image symmetry
96 index
L/W = 1.073 T/W = 0.484 T/L = 0.451
P/W = 0.442 C/W = 0.188
H/W = (P+C)/W+0.02 = 0.650
P/H = 0.680 C/H = 0.289
Vol./W^3 = 0.247

Addition # 5 - This will work in R.I. 1.62 to 1.76 with no changes. I prefer it in a medium to light colored Tourmaline, which is what the shape is designed for… It is fast and easy to cut, it is really a "Money Cut".
