So hand jewellery is kind of a thing lately. ShopDesignSpark calls this a ring bracelet, and offers it with a few different stone options. This one comes in lapis set in sterling silver and is indeed a ring with a bracelet. It’s gold plated on sterling and the nice thing is that because the chain basically “sits” behind your finger, it doesn’t need to be sized as a (real) ring would be.
This sells for USD$60. Rock the casbah, baby.
