These earrings are a simple iterative fractal design and are meant to be part of a set along with this pendant, which uses the same fractal with one further iteration.
Is this piece not quite what you are looking for? You can load this design into the Celtic Knot Creator by clicking here, and then customize it and make it your own! You can do as little as tweaking its size or shape, or as much as completely redesigning it. You can then upload your customized version to Shapeways and order your own, one-of-a-kind set of earrings.
