93.9% Light Return
Angles for R.I. = 1.62
43 facets + 12 facets on girdle = 55
6-fold, mirror-image symmetry
96 index
L/W = 1.071 T/W = 0.304 T/L = 0.284 P/W = 0.433
C/W = 0.184 H/W = (P+C)/W+0.02 = 0.637 P/H = 0.680 C/H = 0.289 Vol./W^3 = 0.216

Addition # 10 – This is fun and fast to cut, I like it in medium colored materials, because it is bright. Cut in refractive indexes 1.62 to 1.76 with no changes. Note: The P3 tier just cuts in to look right, you can vary it to fit the rough.
