Angles for R.I. = 1.54
40 facets + 10 facets on girdle = 50
5-fold, mirror-image symmetry
80 index
L/W = 1.051 P/W = 0.435 C/W = 0.172
H/W = (P+C)/W+0.02 = 0.627
P/H = 0.693 C/H = 0.275
Vol./W^3 = 0.199

Addition # 9 - This works well in any material, but to see the star reflection a light to medium saturation works best. This is great for earrings and sets. I prefer it cut in a large stone so the star shows. Cut in refractive 1.54 to 2.14 with no changes.
