Antique custom fidget signet ring 14k gold with onyx face and moving diamond

This signet ring was custom made by a jeweler, and has been passed down through my family. This 14 k gold statement ring has a black onyx face with a moving diamond. The diamond can be spun in a circle around the middle of the ring. Framed by more gold and diamonds. This piece weighs almost 15g. A beautiful ring. Perfect for all genders.
