91.8% Light Return
Angles for R.I. = 1.54
28 facets + 4 facets on girdle = 32
4-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.435 C/W = 0.226
H/W = (P+C)/W+0.02 = 0.680
P/H = 0.639 C/H = 0.332
Vol./W^3 = 0.264
Addition # 9 - Cut this in refractive indexes 1.54 to 1.93 with no changes. A table can be cut if the stone is large. This is designed for light colors and works well in about any material.
