I've been on a bit of a checker slump lately. This particular design kept failing until I just threw in some radial symmetry. It turned out pretty nice, with some interesting radial symmetry, with great tilt performance! It's also intended to be used for shallower nodules of tourmaline, and should work great there as well. I prefer this cut in sunset tourmaline, but works in materials from topaz to rutile (RI = 1.61 - 2.62) with no changes.
