Earrings made from one slab of polymer clay, but lot of work and mind behind it, and there are whole 9 variations of this design, starting with the smallest ones and ending with bigger ones with gold-plated pendant.
They're handmade of polymer clay which is a lightweight material and very durable after baked in the oven, and assembled with gold plated parts. The parts can contain small amounts of nickel but if you want them completely nickel free, ask for a change to silver or stainless steel and it will be done.
