Thank you, everyone. A little about the image. The jewel was made with a 1600x1200 fractal image. I expanded the canvas to 3200x1200 and copied the image over flipped horizontally. Then I expanded the canvas again to 3200x2400. so that the fractal was across the top. Then I did a filter-polar coordinates to it to create the jewel that looked like it curved at the edges. Made an interesting jewel, I think.
