Having written a simple triangle checkerboard, I decided I wanted to go one step down. This crown is basically halfway between "Simple Triangle Checkerboard" and "Triforce", and it looks surprisingly good for what it is. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer it in vermarine. Suggested size = 6-12 mm
