78% Light Return
Angles for R.I. = 1.98
67 facets + 12 facets on girdle = 79
2-fold, mirror-image symmetry
96 index
L/W = 1.500 T/W = 0.751 T/L = 0.501
P/W = 0.592 C/W = 0.282
H/W = (P+C)/W+0.02 = 0.895
P/H = 0.662 C/H = 0.315
Vol./W^3 = 0.468

Addition # 2 - This is a little hard to cut. The crown can be hard to get to meet, roughing in the table helps. This makes a nice cut in any light to medium material, 1-16cts. Cut in refractive indexes 1.76 to 1.98 with no changes.
