Addition # 11 - Cut in refractive indexes 1.54 to 2.14 with no changes. The crown step can be adjusted. Note: The corners are floating, cut them as close to the diagram as you can. This is good for watermelon and single color material. The steps on the crown can vary to match rough, but deeper stones work best.
