75% Light Return
Angles for R.I. = 1.54
53 facets + 12 facets on girdle = 65
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.505 T/L = 0.505
P/W = 0.460 C/W = 0.226
H/W = (P+C)/W+0.02 = 0.706
P/H = 0.651 C/H = 0.320
Vol./W^3 = 0.279

Addition # 1 – This design is a little harder to cut than it looks, so watch the meets. It has nice flash and is not that hard to cut (for a modified square). Cut in refractive indexes 1.54 to 1.93 (85%) with no changes. It makes a nice stone in light to medium material, 1-6cts.
