86.2% Light Return
Angles for R.I. = 1.62
119 facets + 20 facets on girdle = 139
2-fold, mirror-image symmetry
L/W = 1.287 T/W = 0.791 T/L = 0.614 P/W = 0.562
C/W = 0.162 H/W = (P+C)/W+0.02 = 0.744 P/H = 0.755 C/H = 0.218 Vol./W^3 = 0.393
Addition # 12 - Cut to meet C6. Cut in refractive indexes 1.62 to 2.14 with no changes. Note: This is a little different to cut, the P2 over cuts the P1 leaving the breaks out at the girdle. Cut all the girdle facets as evenly as you can. P3 splits P1 at the girdle. Cut the P3 to center point and cut evenly from both sides a little at a time. You can leave the L/W a little long on the curved ends and them cut to match the P3.
Think out side the box... Cutting "Fancy"
