Angles for R.I. = 1.54
49 facets + 8 facets on girdle = 57
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.493 T/L = 0.493
P/W = 0.452 C/W = 0.153
H/W = (P+C)/W+0.02 = 0.625
P/H = 0.723 C/H = 0.245
Vol./W^3 = 0.249
Addition # 2 - This takes a little cutting, you might have to cut the top a couple of times to get it. When you have done it once it gets easier. About any material (I like a good Amethyst) 1-12cts. Cut in refractive indexes 1.54 to 2.14 (88%) with no changes.
