85.4% Light Return
Angles for R.I. = 1.54
15 facets + 4 facets on girdle = 19
2-fold symmetry
96 index
L/W = 1.000 T/W = 0.927 T/L = 0.927 P/W = 0.529
C/W = 0.148 H/W = (P+C)/W+0.02 = 0.697 P/H = 0.759 C/H = 0.212 Vol./W^3 = 0.380

Addition # 11 – Cut in refractive indexes 1.54 to 2.14 with no changes. This is designed for color and will mix, so be sure that your colors mix well. This is a little different to cut but not hard with the exception of tweaking the meets on the crown.
