L/W = 1.075 T/W = 0.470 T/L = 0.437
P/W = 0.419 C/W = 0.223
H/W = (P+C)/W+0.02 = 0.663
P/H = 0.633 C/H = 0.337
Vol./W^3 = 0.241

Addition # 7 – I designed this for a nice size yellow/green Mali Garnet. This is very deep to help color and dispersion. Notice the facets are smaller and they cross each other to help increase sparkle. This works well in man-made Sapphire, Zircon, and CZ with no changes.
