I happened to like the rendering of my "Fallen Star" design, but I wanted something with a much more clear star pattern. I also wanted a starburst directly underneath the table. Designed for golden orthoclase, but can be cut in any material from feldspar to CZ (RI = 1.52 - 2.16) with no changes. Suggested size = 6-10 mm
