91.2% Light Return
Angles for R.I. = 1.54
36 facets + 12 facets on girdle = 48
6-fold, mirror-image symmetry
96 index
L/W = 1.088 P/W = 0.441 C/W = 0.201 H/W = (P+C)/W+0.02 = 0.662
P/H = 0.666 C/H = 0.304
Vol./W^3 = 0.218

Addition # 9 – Depending on the size of the P3, P4(G), you may need to adjust the C2 angle. This is a new design concept that is fast and easy to cut. These are made to be Money Cuts. Cut this in refractive index 1.54 to 2.14 with no changes.
