92.8% Light Return
Angles for R.I. = 1.62
41 facets + 10 facets on girdle = 51
5-fold symmetry
80 index
L/W = 1.051 T/W = 0.307 T/L = 0.292
P/W = 0.414 C/W = 0.198
H/W = (P+C)/W+0.02 = 0.632
P/H = 0.655 C/H = 0.313
Vol./W^3 = 0.217
Addition # 9 - This is fun and works in about any material. I like a large stone because the star can easily be seen. Cut in refractive indexes 1.62 to 2.14 with no changes. Try this in some orange Citrine.
