Angles for R.I. = 1.73
50 facets + 14 facets on girdle = 64
1-fold, mirror-image symmetry

L/W = 1.302 T/W = 0.623 T/L = 0.479
P/W = 0.428 C/W = 0.192
H/W = (P+C)/W+0.02 = 0.641
P/H = 0.669 C/H = 0.300
Vol./W^3 = 0.260

Addition # 4 – This cuts pretty much like a round brilliant, it works well and is set up for Garnet. I use it a lot in Rose Malaya Garnet, cut to center point on the Pavilion and then cut the girdle to meet, 1cts+. Works in Spinel, Sapphire, as well as man-made materials.
