96 index
L/W = 1.000 T/W = 0.656 T/L = 0.656
P/W = 0.462 C/W = 0.099
H/W = (P+C)/W+0.02 = 0.581
P/H = 0.795 C/H = 0.171
Vol./W^3 = 0.220

Addition # 7 - This is a design made for accent stones. The best way to cut this is to cut a square girdle first. When I say edge on P4(G), I mean cut to the long edge. The best way to do it is cut until the P4(G)just meets 72 index (cutting the pavilion). This is actually pretty easy and works great for 1.54 to 1.93 with no changes. I like it cut in red Garnet.
