91.9% Light Return
Angles for R.I. = 1.54
51 facets + 10 facets on girdle = 61
5-fold, mirror-image symmetry
80 index
L/W = 1.051 T/W = 0.244 T/L = 0.232
P/W = 0.435 C/W = 0.257
H/W = (P+C)/W+0.02 = 0.712
P/H = 0.611 C/H = 0.361
Vol./W^3 = 0.234

Addition # 9 – This is good in about any material and I designed it to be cut in a large stone. It works best in lightly saturated materials and has a very interesting look. Cut in refractive indexes 1.54 to 1.93 with no changes.
