Rings and bracelets can get scratches, loose settings, and broken links. For a scratched ring, polishing with a jewelry cleaning cloth or a sophisticated polishing formula will restore its shine. For loose stones, you can use tweezers to reseat the stone and, with pliers, tighten the prongs. If a stone is missing, generally, you might be able to find a replacement online or locally at a hobby shop. Repairing broken bracelets requires knowledge of the character of the material used. Metal bracelets can be repaired normally with jump rings or solder, while leather or bead bracelets can be repaired by adhesive or fresh stringing.
