87.8% Light Return
Angles for R.I. = 1.54
51 facets + 12 facets on girdle = 63
1-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.445 T/L = 0.445 P/W = 0.442
C/W = 0.184 H/W = (P+C)/W+0.02 = 0.645 P/H = 0.684 C/H = 0.285 Vol./W^3 = 0.194

Addition # 11 – Cut this in refractive indexes 1.54 to 2.14 with no changes. This is designed for light to medium colored material, no heavy shiller. This works best when the color spot is centered and surrounded by gold/clear material.
