91.4% Light Return
Angles for R.I. = 1.54
36 facets + 8 facets on girdle = 44
4-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.450 C/W = 0.219
H/W = (P+C)/W+0.02 = 0.690
P/H = 0.653 C/H = 0.318
Vol./W^3 = 0.267

Addition # 9 – Note: The P3(G) is variable, cut it to look like the diagram. The corners can be adjusted to the rough. Cut in refractive indexes 1.54 to 1.76 with no changes. This is fast to cut and works well in a large size stone. Nice in medium colored Garnets.

Random – Cosine – ISO
