84.6% Light Return
Angles for R.I. = 1.54
59 facets + 16 facets on girdle = 75
2-fold, mirror-image symmetry
96 index
L/W = 1.401 T/W = 0.753 T/L = 0.537
P/W = 0.437 C/W = 0.141
H/W = (P+C)/W+0.02 = 0.598
P/H = 0.731 C/H = 0.235

Addition # 4 - This cuts like a round brilliant, for those of you who have cut my "Brilliant Pear" type designs, this will be very similar. Cut to center point on the Pavilion, then cut the girdle… Light return is very good, 1cts+. This works in Tourmaline, Topaz, and Peridot.
