The impetus for writing this highly-specific design outline was a massive inside joke between a bunch of the younger gemcutters and designers, but somehow it ended up looking really good. Test-cut by Phil Lagas- Rivera of Alternative Gems, who got extremely interesting dichroic effects along the X vs. Y axes of the stone. Works in materials from petalite to corundum (RI = 1.50 - 1.76) with no changes, but can be pushed higher.
