81.2% Light Return
Angles for R.I. = 1.54
45 facets + 8 facets on girdle = 53
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.392 T/L = 0.392
P/W = 0.529 C/W = 0.164
H/W = (P+C)/W+0.02 = 0.713
P/H = 0.742 C/H = 0.230
Vol./W^3 = 0.330
Addition # 6 - This can be cut in refractive indexes 1.54 to 1.93 (88.6%) with no changes. I like this in Zircon… Notice it is quite deep, it works well in light colored material.
