The short answer: choose a clasp that closes with a positive click, sits flat on the wrist and has a safety catch, and match its strength to the weight of the bracelet. Lobster and box clasps with a figure eight safety are among the most secure for fine jewellery.
A bracelet is only as secure as its clasp. This guide helps you choose one you can trust.
Common clasps
| Clasp | Security | Notes |
|---|---|---|
| Lobster | Good | A spring gate that opens with a lever. |
| Box with safety | High | A tongue slides into a box and a safety catch adds protection. |
| Spring ring | Moderate | Common on fine chains. |
| Toggle | Moderate | A bar passes through a ring, decorative. |
| Magnetic | Lower for heavy pieces | Easy to use but not suited to valuable bracelets. |
Safety catches
A figure eight safety catch is a small clip on either side of a box clasp that stops it opening if the main clasp is knocked. It is a sensible addition to a diamond bracelet.
Hidden clasps
On a tennis bracelet, the clasp can be designed to look like one of the links, with a stone set into the box so the line of diamonds runs unbroken around the wrist. It looks seamless, and it still works with a safety catch. A hidden clasp takes a little more thought in the design, so mention it early if you would like one.
Match to the bracelet
- A heavy tennis bracelet needs a strong box clasp with a safety.
- A fine chain bracelet suits a lobster clasp.
- A bangle often has a hinge and a secure closure.
Our diamond tennis bracelet guide covers clasps for tennis styles in more detail.
Bangles and hinges
A hinged bangle opens on one side and closes with a catch on the other. A good catch clicks firmly into place, and many have a secondary safety bar or a push button that has to be pressed to open. Check that the hinge moves smoothly and that the bangle closes without a gap. A solid bangle with no opening relies on fit alone, so it needs to pass over the widest part of the hand.
Ease of use
If you struggle to fasten a bracelet on your own, tell us. A clasp you can open easily is more likely to be closed properly every time. Some people find a lobster clasp easier, and others prefer a box clasp with the safety catch released by a gentle push.
Wear and checks
Clasps wear. Have the clasp checked from time to time, and replace worn parts. Listen for a clear click when you close it, and tug gently on the bracelet to confirm that it is shut. A spring that feels weak, a tongue that no longer clicks or a catch that opens with a light knock are all signs it is time for attention.
Placement on the wrist
A clasp that sits on the underside can feel uncomfortable at a desk, while one that sits on the side can catch on clothing. We can talk through where the clasp sits when we plan the design, so it lies flat and out of the way.
Our approach
We discuss the clasp as part of the design and choose one that suits the weight and use of the bracelet. Nothing is made until you approve the design in writing, and our standard making time is 5 to 6 weeks, which can vary with your location and how busy we are. Pieces start from £600.
- Pick the bracelet style.
