90.1% Light Return
Angles for R.I. = 1.54
35 facets + 10 facets on girdle = 45
5-fold, mirror-image symmetry
80 index
L/W = 1.051 P/W = 0.450 C/W = 0.194
H/W = (P+C)/W+0.02 = 0.664 P/H = 0.678 C/H = 0.292
Vol./W^3 = 0.211

Addition # 10 – This is quick and fun. Cut in refractive indexes 1.54 to 2.14 with no changes. This makes great earrings and makes an interesting ring or pendant stone. About any color and saturation will work well.
