Addition # 10 - A table can be cut on a large stone. This is a quick, easy cut with a very nice flower type of flash. Cut this in refractive indexes 1.54 to 2.14 with no changes. About any stone saturation works well, I prefer lighter colors. Note: The C2 only meets at the corners, just float the other facets in as evenly as you can. A table can be cut in on larger stones.
