87.3% Light Return
Angles for R.I. = 1.54
51 facets + 8 facets on girdle = 59
2-fold, mirror-image symmetry
96 index
L/W = 1.322 T/W = 0.630 T/L = 0.476
P/W = 0.573 C/W = 0.164
H/W = (P+C)/W+0.02 = 0.757
P/H = 0.757 C/H = 0.216
Vol./W^3 = 0.375

Addition # 5 - Notice the P1 tier only meets the girdle at 96-24-48-72. The C5 tier is made to adjust the L/W if you are off a bit. This is a little tricky for a new cutter. Getting all the crown meets correct is not easy. This can be cut in R.I. 1.54 to 1.76 (89%) with no changes.
