Angles for R.I. = 1.62
23 facets + 7 facets on girdle = 30
1-fold, mirror-image symmetry
96 index
L/W = 1.146 T/W = 0.544 T/L = 0.474
P/W = 0.420 C/W = 0.205
H/W = (P+C)/W+0.02 = 0.645
P/H = 0.651 C/H = 0.318
Vol./W^3 = 0.219

Addition # 7 - This is an interesting design, it cuts fast and easy. The shape is a bit different, but I usually seem to have some rough that will cut this. Cut to center point, be careful of the L/W. Other than L/W this is easy… Cut in refractive Indexes 1.62 to 1.93(83.6%) with no changes.
