Angles for R.I. = 1.54
25 facets + 4 facets on girdle = 29
2-fold, mirror-image symmetry
96 index L/W = 1.140 T/W = 0.272
T/L = 0.239 P/W = 0.327 C/W = 0.262
H/W = (P+C)/W+0.02 = 0.609
P/H = 0.537 C/H = 0.430
Vol./W^3 = 0.177

Addition # 8 - This is a fast design to cut, notice that it is not square. I designed it for earrings in light colors and it works well in Quartz. Cut in refractive indexes 1.54 to 1.93 with no changes. I like the high crown on this design, it reads well and is interesting to look at.
