79.7% Light Return
Angles for R.I. = 1.62
102 facets + 15 facets on girdle = 117
1-fold, mirror-image symmetry
96 index
L/W = 1.032 T/W = 0.474 T/L = 0.459 P/W = 0.447
C/W = 0.180 H/W = (P+C)/W+0.02 = 0.647 P/H = 0.691 C/H = 0.278 Vol./W^3 = 0.224

Addition # 12 – Cut in refractive indexes 1.62 to 2.14 with no changes. This cuts almost like the Glitter Pear, but the top of the heart is cut, notice it is just replacing some of the girdle facets. Expect to have to tweak C7-C10. Note: Cut to L/W, P9 can be cut in to help with P7.
