This design was written for Jordan Wilkins, who had a dark iron-bearing garnet that needed a square cushion. The P1 and P2 facets are close in index and angle by design so that they function more like a single, large, flat reflector facet, which lightens dark garnets with "flash". P2 cuts very quickly, so be careful. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes.
