94.6% Light Return
Angles for R.I. = 1.54
20 facets + 4 facets on girdle = 24
4-fold symmetry
96 index
L/W = 1.000 P/W = 0.458 C/W = 0.144
H/W = (P+C)/W+0.02 = 0.622
P/H = 0.736 C/H = 0.232
Vol./W^3 = 0.241

Addition # 3 – Fast cutting with a nice bright flash, this design makes a good stone when you want to cut something that’s not involved. I use it for earrings mostly, cut it in any material in 4-8mm is best. On larger stones a table is a good idea, cut to meet C2,C3… Cut in refractive indexes 1.54 to 2.14 (92.3%) with no changes.
