90.8% Light Return
Angles for R.I. = 1.54
36 facets + 6 facets on girdle = 42
6-fold, mirror-image symmetry
96 index
L/W = 1.155 P/W = 0.450 C/W = 0.211
H/W = (P+C)/W+0.02 = 0.681
P/H = 0.661 C/H = 0.309
Vol./W^3 = 0.229

Addition # 9 - This works best in light colors. Cut in refractive indexes 1.54 to 1.76 with no changes. I designed this for 10mm earrings and it is quite striking in Rose de France. On a very large stone a table can be cut to meet C4. This makes a very interesting stone.
