This deceptively simple design has incredible performance, with absurdly high amounts of scatter and contrast, and an excellent reflection pattern that varies drastically with increasing refractive index. It's also really fast to cut! Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer lavender spinel. Suggested size = 6-15 mm
