89.6% Light Return
Angles for R.I. = 1.54
105 facets + 16 facets on girdle = 121
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.286 T/L = 0.286
P/W = 0.413 C/W = 0.189
H/W = (P+C)/W+0.02 = 0.621
P/H = 0.664 C/H = 0.304
Vol./W^3 = 0.170

Addition # 8 – This is an interesting cut and it works well in a large stone. Cut it in refractive indexes 1.54 to 1.76 with no changes. Medium saturated materials work well and I like this in Bolivian Amethyst.
