Angles for R.I. = 1.54
37 facets + 6 facets on girdle = 43
6-fold, mirror-image symmetry
96 index
L/W = 1.155 T/W = 0.278 T/L = 0.241 P/W = 0.435
C/W = 0.242 H/W = (P+C)/W+0.02 = 0.696 P/H = 0.624 C/H = 0.347 Vol./W^3 = 0.246

Addition # 10 – Cut this in refractive indexes 1.54 to 2.14 with no changes. This is another great earring design, I like it in light to medium saturations. It has great reflections and mirrors. Large is better because the reflections show up better. Note: C3 just cuts to look right, you can get different stars by varying the C3.
