I was looking around, trying to find pictures of what a traditional "Radiant Square" cut was supposed to be, and I saw an outline for an "Old European" cut. I thought it looked nice, so I recreated it and improved it a little. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer it in blue spinel. Suggested size = 7-12 mm
