Angles for R.I. = 1.73
58 facets + 8 facets on girdle = 66
2-fold, mirror-image symmetry
96 index
L/W = 1.328 T/W = 0.256
T/L = 0.193 P/W = 0.167 C/W = 0.170
H/W = (P+C)/W+0.02 = 0.357 P/H = 0.469
C/H = 0.475
Vol./W^3 = 0.298

Addition # 8 – This is designed for darker colored materials like Garnet. It will help give life to dark materials, but it will also work well in medium colored stones of any refractive index. This is designed to be bezel set so that the light and color will show from both sides. L/W is not critical and can vary some what. This cuts fast and is not hard to do…
