Addition # 12 - Cut this in refractive indexes 1.54 to 2.14 with no changes. This is a great cut for Beryl, and I like it in Aquamarine. This cuts pretty easy and will work well in light to medium saturated materials. Note: The P3(G)cuts into about 25% of width, it does not have a meet and can vary a little. The C8 can be cut earlier, but it is easy to just tweak to make the meets.
