How do I repair a broken bracelet clasp or replace it with a better one?

ZKZ Editorial TeamMain answer · Product & gemmology desk

A clasp is a moving part, so it wears. A loose clasp that still has an intact spring or tongue can sometimes be adjusted, but a worn or bent one is better replaced, ideally with a type suited to the bracelet's weight.

Common clasp types

• Lobster claw: a spring-loaded hook; common and secure, but the spring can weaken.
• Spring ring: a small round clasp; light, but easy to wear out.
• Box clasp with safety catch: common on tennis bracelets; the tongue can loosen.
• Toggle: a bar through a ring; can slip if the ring is too large.
• Magnetic: convenient, but less secure for heavy or valuable pieces.

Repair or replace

Our advice Repair is reasonable when the problem is a bent tongue or a loose join that can be tightened. Replace when a spring has failed, the metal is worn thin or the clasp does not match the weight of the bracelet.

1. Show the bracelet to a jeweller and ask them to test the clasp under gentle tension.
2. Ask for the cause: wear, a bent part or a poor join.
3. Compare a repair quote with the cost of a new, stronger clasp.

Choosing a replacement

Our advice Choose a clasp type that is secure and easy to use. For a valuable bracelet, a clasp with a safety catch or a figure-of-eight safety is worth considering, as it gives a second layer of protection.

It depends The best clasp depends on bracelet weight, your wrist and how often you open it. A clasp that is hard to close for you may be one you avoid fastening properly.

While you wait

Fact Jewelers Mutual advise not to keep wearing a damaged piece and to store it safely until it can be repaired.

Checking clasps

Our advice Test clasps every few weeks by gently tugging the bracelet after closing it. Replace a clasp before it fails, not after you lose the bracelet.

Uncertain We cannot say how long a given clasp will last. Wear depends on use, so inspect it regularly.
