80.6% Light Return
Angles for R.I. = 1.54
40 facets + 4 facets on girdle = 44
8-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.435 C/W = 0.264
H/W = (P+C)/W+0.02 = 0.719 P/H = 0.605 C/H = 0.368
Vol./W^3 = 0.307

Addition # 10 Note: The C3 tier only meets C1 every other facet, the 12-36-60-84 facets float. Cut them as evenly as you can. Cut this in refractive indexes 1.54 to 2.14 with no changes. This is ideal for light to medium saturated materials. A table can be cut on larger stones.
