82.2% Light Return
Angles for R.I. = 1.56
53 facets + 12 facets on girdle = 65
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.543 T/L = 0.543
P/W = 0.447 C/W = 0.196
H/W = (P+C)/W+0.02 = 0.663
P/H = 0.674 C/H = 0.296
Vol./W^3 = 0.266

Addition # 3 – This design is a little harder to cut than it looks at first glance. The C5 facets have to be cut exact for the table to work. If your machine has a keyed dop you can cut the table first(then C5), 1-8cts. Cut in refractive indexes 1.56 to 2.14 (84.3%) with no changes.
