By Jeff R. Graham
Angles for R.I. = 1.54
57 facets + 8 facets on girdle = 65
8-fold, mirror-image symmetry
L/W = 1.000 T/W = 0.489 T/L = 0.489 P/W = 0.697
C/W = 0.206 H/W = (P+C)/W+0.02 = 0.923 P/H = 0.755 C/H = 0.223 Vol./W^3 = 0.391
Addition # 11 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is designed for light colored rough, and is very good in Aquamarine. This is fairly fast and easy to cut. This can be cut to the girdle instead of center point to save rough.
