What to do
- Clean the clasp with a soft cloth and a little jewelry cleaner or mild soap to rule out gunk buildup.
- Check the small jump ring connecting the clasp to the chain; if it's open, needle-nose pliers can gently close the gap.
- If the clasp spring is weak but not broken, a slight squeeze with pliers on the moving lever can sometimes restore tension.
- For a fully broken clasp, most jewelry or craft stores sell replacement clasps in matching styles and metal tones.
- To replace it, open the jump ring on one end, remove the old clasp, and attach the new one, then close the jump ring fully.
- For fine or valuable jewelry, have a jeweler replace the clasp to match the metal and avoid damaging the piece.
