82.2% Light Return
Angles for R.I. = 1.62
45 facets + 8 facets on girdle = 53
2-fold, mirror-image symmetry
L/W = 1.331 T/W = 0.378
T/L = 0.284 P/W = 0.453
C/W = 0.190 H/W = (P+C)/W+0.02 = 0.662
P/H = 0.683 C/H = 0.287
Vol./W^3 = 0.257
Addition # 8 - This cuts fairly easily and the L/W can vary slightly with no problems. Cut in refractive indexes 1.62 to 1.93 with no changes. This is good in about any material, but I prefer medium to light saturation.
