The "invincibility star" or "super star", shiny and full of detail. You can pass a chain through the holes on top, as long as the chain is small enough (the hole is 3mm x 2mm).
The pictures are from Gold-Plated Brass (super shiny, real gold!) and Polished Bronze Steel, but it's also available in a bunch of other materials.
