This is my stylized sun pendant: Happy Sun, it looks great with gold finish, as you can see by the pictures attached. This is a 1 inch version (2.54 cm) - The attached photos are of the 3 cm version, in 18k gold plated. The chain and the ring showed at the photos are not part of the pendant.
It is now available for buying on this Shapeways shop:
