81.3% Light Return
Angles for R.I. = 1.54
12 facets + 3 facets on girdle = 15
1-fold, mirror-image symmetry
96 index
L/W = 1.866 T/W = 0.913 T/L = 0.489
P/W = 0.431 C/W = 0.127
H/W = (P+C)/W+0.02 = 0.578
P/H = 0.746 C/H = 0.219
Vol./W^3 = 0.257

Addition # 7 – This cuts fast and easy. It is a good idea to nick the corners a little bit so they are not too sharp. Cut in refractive indexes 1.54 to 1.73 (81%) with no changes. The L/W can vary with no problems…
