I honestly have no idea how or why I wrote this design. I was probably REALLY sleep deprived, since I distinctly remember the sapphire render looking like a personified "mouth" of the ocean, with vicious teeth. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer absurdly blue sapphire. Suggested length = 7-15 mm
