Angles for R.I. = 1.62
53 facets + 12 facets on girdle = 65
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.414 T/L = 0.414
P/W = 0.408 C/W = 0.229
H/W = (P+C)/W+0.02 = 0.657
P/H = 0.621 C/H = 0.349
Vol./W^3 = 0.227

Addition # 7 – This is straight forward to cut and has a very nice look. I like the petal like crown. This makes very pretty earrings. Cut it in refractive indexes 1.62 to 2.14 with no changes.
