I've been trying to write designs where the girdle outline is a square oriented on the 96, but the pavilion is a square oriented on the 12. I finally got one to work - it performs surprisingly well in a range of saturations. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer it in sunset tourmaline. Suggested size = 7-15 mm
