Originally, I was just messing around with reflecting a previous design ("Rectus Quadratus"). Somehow, it looked a bit like a Princess cut, so I worked on that angle and got a Princess-style reflection without the typical chevrons. I like this in emerald, but it works in materials from feldspar to CZ (RI = 1.52 - 2.16) with no changes. Suggested size = 6-12 mm
