This design is a modification of my "Crystal Hexagon" design, but re-written for shallower material. This particular version definitely does NOT have the Portuguese effect, but it still looks amazing in paler materials. Works in materials from quartz to rutile (RI = 1.54 - 2.62) with no changes, but looks best in icy topaz. Suggested size = 10-30 mm
