85.7% Light Return
Angles for R.I. = 1.54
48 facets + 8 facets on girdle = 56
2-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.453 C/W = 0.212
H/W = (P+C)/W+0.02 = 0.685
P/H = 0.661 C/H = 0.309
Vol./W^3 = 0.225

Addition # 6 - A table can be cut in to meet C5 on a larger stone or a light colored stone. It is a good idea so that you do not have the hole at the apex. This design works very well for saturated material and is really what I designed it for. It will cut well in Peridot, Garnet, Sapphire, Spinel, and man-made materials.
