80.8% Light Return
Angles for R.I. = 1.54
73 facets + 8 facets on girdle = 81
2-fold, mirror-image symmetry
L/W = 1.000 T/W = 0.323 T/L = 0.323
P/W = 0.470 C/W = 0.163
H/W = (P+C)/W+0.02 = 0.653
P/H = 0.720 C/H = 0.249
Vol./W^3 = 0.243
Addition # 8 - Cut this in refractive indexes 1.54 to 2.14 (89.5%) with no changes. The crown on this is a little complicated, and I do not recommend this for a novice. The crown can be cut in another order and may take some adjusting to make all the meets depending on your faceting machine. This is really nice in higher refractive index materials like Zircon and Sapphire.
