The most common bracelet closure is the lobster clasp, because it is secure, cheap and easy to fit to an extension chain. Spring rings, toggles, magnetic clasps, box clasps and sliding adjusters are the other main options. The right choice depends on the weight of the bracelet, the customer and how easy it must be to put on with one hand.
A bracelet that falls off is a lost customer, so the clasp deserves the same attention as the design.
The main closures
- Lobster clasp: a spring-loaded hook shaped like a claw. Secure and the default for chains and charm bracelets.
- Spring ring: a small round clasp with a sliding catch. Cheaper but fiddly and weaker than a lobster.
- Toggle: a bar that passes through a ring. Easy to use and decorative, but needs some tension to stay closed.
- Magnetic: two magnets that snap together. Easiest for older customers, but can open under a knock.
- Box clasp: a tongue that clicks into a box, often with a safety catch. Used on tennis bracelets and heavier pieces.
- Sliding adjuster or knot: used on bead, thread and chain bracelets that adjust to any wrist.
Matching clasp to bracelet
Light chain bracelets work well with lobster clasps and a short extension. Heavy or stone-set bracelets need a box clasp with a safety catch. Toggles suit chunky link designs where the toggle is part of the look. Magnetic clasps suit light bracelets and customers who struggle with small clasps.
Avoid magnets in children's jewellery. Swallowed magnets are a serious hazard, and several markets have specific rules on magnets in children's products.
Quality checks
- The clasp opens and closes smoothly and springs back fully.
- Jump rings are closed tightly or soldered, with no gap a chain could slip through.
- The clasp is plated in the same colour and thickness as the bracelet.
- Magnetic clasps hold under a gentle pull.
