Angles for R.I. = 1.54
20 facets + 4 facets on girdle = 24
4-fold, mirror-image symmetry

L/W = 1.000 P/W = 0.435 C/W = 0.192
H/W = (P+C)/W+0.02 = 0.646
P/H = 0.672 C/H = 0.297
Vol./W^3 = 0.237

Addition # 9 – This is so simple and fast it’s hard to believe how nice the cut really is. Try it in about any material, I especially like it in Amethyst. It’s good for red Garnets and makes great accent stones.
