Angles for R.I. = 1.54
30 facets + 6 facets on girdle = 36
6-fold symmetry
96 index
L/W = 1.155 P/W = 0.450 C/W = 0.242
H/W = (P+C)/W+0.02 = 0.713
P/H = 0.632 C/H = 0.340
Vol./W^3 = 0.238
Addition # 9 - This one is just fast and fun to cut. I have several other cuts similar to this, but the reflections on this one are quite nice. Any material, about any size. A table is a good idea on large stones. Cut in refractive indexes 1.54 to 1.93 no changes.
