Angles for R.I. = 1.54
66 facets + 8 facets on girdle = 74
8-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.218 T/L = 0.218
P/W = 0.742 C/W = 0.742
H/W = (P+C)/W+0.02 = 1.504
P/H = 0.493 C/H = 0.493
Vol./W^3 = 0.617

 

Addition # 14 – This cuts easily and works well in most any material. I like it in medium colored Amethyst or Citrine.
