94.5% Light Return
Angles for R.I. = 1.54
36 facets + 4 facets on girdle = 40
4-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.435 C/W = 0.179
H/W = (P+C)/W+0.02 = 0.634
P/H = 0.686 C/H = 0.283
Vol./W^3 = 0.250

Addition # 9 – This is simple to cut and works well in about any material. Cut in refractive indexes 1.54 to 2.14 with no changes. This works well in saturated materials like dark Citrine and Amethyst.
