Angles for R.I. = 1.54
46 facets + 9 facets on girdle = 55
3-fold, mirror-image symmetry
96 index
L/W = 1.004 T/W = 0.348 T/L = 0.346
P/W = 0.387 C/W = 0.169
H/W = (P+C)/W+0.02 = 0.576
P/H = 0.671 C/H = 0.294
Vol./W^3 = 0.174
Addition # 9 - This is interesting and cuts fairly fast. It works well in about any material. Cut in refractive indexes 1.54 to 2.14 with no changes. I like this in Sapphire, especially light to medium colors.
