Angles for R.I. = 1.54
16 facets + 4 facets on girdle = 20
L/W = 1.000 P/W = 0.450 C/W = 0.165
H/W = (P+C)/W+0.02 = 0.635 P/H = 0.709 C/H = 0.259 Vol./W^3 = 0.258
Addition # 11 – Cut in refractive indexes 1.54 to 2.14 with no changes. This is easy, fast to cut, and designed for earrings and thin rough. It will work in color or light shiller. Large sized stones work best and I would suggest 8mm and up.
