87.5% Light Return
Angles for R.I. = 1.62
57 facets + 4 facets on girdle = 61
L/W = 1.000 T/W = 0.262 T/L = 0.262 P/W = 0.405
C/W = 0.225 H/W = (P+C)/W+0.02 = 0.650 P/H = 0.623 C/H = 0.346 Vol./W^3 = 0.286
Addition # 10 - Cut this in refractive indexes 1.62 to 2.14 with no changes. This is not easy to cut. Cutting the crown to center point to make the facets even helps. Note: C3 only meets C2 at 96-24-48-72. Cut the rest of the tier as evenly as possible.
