Angles for R.I. = 1.73
43 facets + 12 facets on girdle = 55
1-fold, mirror-image symmetry
96 index
L/W = 1.155 T/W = 0.443 T/L = 0.383
P/W = 0.460 C/W = 0.173
H/W = (P+C)/W+0.02 = 0.653
P/H = 0.704 C/H = 0.265
Vol./W^3 = 0.260

Addition # 7 - This cuts pretty well in Tourmaline (75.4%), and in 1.73 to 1.93 with no changes. L/W=1.155, it's important to be at the correct L/W. Be sure to cut your center point lined up with the dop. Cut P1 and P6 (alternate) to center the stone on your dop. Watch your L/W on this, it is important that it be right. P13 and P14 can be off if you are not right on the L/W. This can be a bit touchy to cut and I do not recommend it for a beginner.
