Addition # 8 – This is a nice one, cut it in about any colored material. It is a little different and the crown, while not hard to cut, can be confusing for a novice. Cut this in refractive indexes 1.54 to 2.14 with no changes. I like this in pink Tourmaline. It is ideal for medium to light colored material. This design has very interesting flash patterns.
