CROWN

Addition # 10 - Cut this in refractive indexes 1.54 to 2.14 with no changes. This is another great earring design, I like it in light to medium saturations. It has great reflections and mirrors. Large is better because the reflections show up better. Note: C3 just cuts to look right, you can get different stars by varying the C3.
