Angles for R.I. = 1.62
37 facets + 6 facets on girdle = 43
6-fold symmetry
96 index
L/W = 1.155 T/W = 0.197 T/L = 0.171 P/W = 0.405
C/W = 0.351 H/W = (P+C)/W+0.02 = 0.776 P/H = 0.522 C/H = 0.453 Vol./W^3 = 0.301

Addition # 13 – Cut in refractive indexes 1.62 to 2.14 with no changes. This is designed for lightly saturated materials. I tend to use it a lot for Afghan material, especially the mint color. This is easy to cut.
