93.9% Light Return
Angles for R.I. = 1.54
29 facets + 4 facets on girdle = 33
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.162 T/L = 0.162
P/W = 0.435 C/W = 0.187
H/W = (P+C)/W+0.02 = 0.641
P/H = 0.678 C/H = 0.291
Vol./W^3 = 0.253

Addition # 9 – Note: Cut the C2 to center point, or as evenly as you can, only the 4 corner facets in the tier meet the girdle. This is designed for about any material, I prefer light to medium saturation so the reflections really show. Try some matched sets, they will sell fast and are fun to cut.
