92.2% Light Return
Angles for R.I. = 1.54
48 facets + 12 facets on girdle = 60
4-fold, mirror-image symmetry
96 index
L/W = 1.000 P/W = 0.435 C/W = 0.200
H/W = (P+C)/W+0.02 = 0.654
P/H = 0.664 C/H = 0.305
Vol./W^3 = 0.263

Addition # 9 – Note: The corners are designed to be variable to fit a piece of rough. Generally cut the corners to look like the diagram. This is an excellent cut in almost any material. On a large stone a table can be cut at C6. Cut in refractive indexes 1.54 to 2.14 with no changes. This is nice in Garnet like Mombo and Rhodolite.
