90.6% Light Return
Angles for R.I. = 1.56
55 facets + 10 facets on girdle = 65
2-fold, mirror-image symmetry
96 index
L/W = 1.414 T/W = 0.188
T/L = 0.133 P/W = 0.594
C/W = 0.258 H/W = (P+C)/W+0.02 = 0.872
P/H = 0.681 C/H = 0.296
Vol./W^3 = 0.494

Addition # 8 – This makes a nice cross if you leave the C8 thru C12 and the table frosted. It will show up well in light colored material. Cut in refractive indexes 1.56 to 2.14 with no changes. Notice the C12 tier is very shallow, I just rub the facets in by hand.
