Angles for R.I. = 1.56
53 facets + 12 facets on girdle = 65
2-fold, mirror-image symmetry

L/W = 1.330 T/W = 0.761 T/L = 0.572
P/W = 0.606 C/W = 0.181
H/W = (P+C)/W+0.02 = 0.807
P/H = 0.751 C/H = 0.224
Vol./W^3 = 0.439
Addition # 5 - This works in R.I. 1.54 (80.1%) to 1.71 (83.3%) with no changes. I designed this for Beryl crystal shapes, there are not a lot of designs that utilize them well. It is a "Money Cut"…
