Wow, this design is simple. It's the simplest possible semiregular tessellation pattern that can be turned into a stone. For something with so few facets, it performs surprisingly well, just like my "Triforce" pattern does. Should work very well for thinner rough without compromising appearance. Written for indicolite, but works in any material from topaz to zircon (RI = 1.61 - 1.93) with no changes.
