You can present this piece of jewelry as a small, magical trick of dexterity or use it as a pretext for lacking any other magic devices. You simply pull the ring out of its anchored place and give the clip and ring to the audience for their inspection. You then ask them to put the ring back where it belongs on the clip. No one will succeed--of course, no one but you.
Consists of 925/000 partially gold-plated silver available in different models.
