73.6% Light Return
Angles for R.I. = 1.62
82 facets + 6 facets on girdle = 88
3-fold, mirror-image symmetry
96 index
L/W = 1.155 T/W = 0.287 T/L = 0.248 P/W = 0.528
C/W = 0.291 H/W = (P+C)/W+0.02 = 0.838 P/H = 0.629 C/H = 0.347 Vol./W^3 = 0.319



Addition # 12 - Cut in refractive indexes 1.62 to 2.14 with no changes. This is good for light to medium saturations and I like it in light colored Tourmaline. It is not hard to cut and makes a striking stone.
