80.6% Light Return
Angles for R.I. = 1.56
27 facets + 7 facets on girdle = 34
1-fold, mirror-image symmetry
96 index
L/W = 1.412 T/W = 0.827 T/L = 0.585
P/W = 0.380 C/W = 0.157
H/W = (P+C)/W+0.02 = 0.557
P/H = 0.682 C/H = 0.282
Vol./W^3 = 0.215

Addition # 7 – This is actually easier to cut than it may look. Cut P1 to P8 and make sure that you have the correct L/W=1.412. NOTE cut the P8 in to get the correct L/W and then cutting P7 is easier… This is not really meet Point. It works well in Tourmaline and Topaz.
