Which Bracelet Clasp Should I Choose? A Guide to Jewellery Clasps

One of the most common questions I get asked as a jewellery maker is: what clasp would you recommend for a bracelet? It's a bit like asking what colour to choose or whether to go for a button or a zip — ultimately it comes down to personal preference, practicality, and budget. Different clasps vary in size, weight, ease of use, and cost, so it's worth understanding your options before you decide.

Here's a breakdown of each clasp type to help you make an informed choice.

Trigger / Lobster Clasp

Trigger clasps are the most common and versatile clasp in jewellery making. A sprung 'trigger' mechanism opens and closes the clasp, and it works beautifully with an extension chain — so you can adjust the length of your bracelet or necklace easily. I use three sizes: small, medium, and large. For bracelets I typically use a medium, as the small can be very fiddly and the large tends to be better suited to necklaces.

Pro: Works with an extension chain for easy size adjustment.
Con: Can be fiddly to fasten, even with a larger clasp.
Cost: The most affordable clasp option.

Toggle Clasp

A toggle clasp consists of a ring on one end and a bar on the other. The bar slides through the ring vertically and then sits horizontally to hold it in place. They can take a little practice to fasten one-handed, but they add a lovely decorative touch to a bracelet. Available in several designs including round and heart-shaped.

Pro: Adds style and a decorative element to the piece.
Con: Can be fiddly; cannot be used with an extension chain.
Cost: Approximately £2.50 more than a medium trigger clasp.

Magnetic Clasp

Magnetic clasps use strong magnets to bring the two halves together, making them much easier to fasten than conventional clasps — ideal if dexterity is a concern. The clasps I use are the strongest I've found, and with a little care they are very secure.

Pro: Very easy to fasten; reduces the risk of damage if snagged on clothing.
Con: Cannot be used with an extension chain; care needed around clothing as the magnet can release if caught.
Cost: £2.50–£5 more than a medium trigger clasp, depending on size.

Slider Ball Clasp

An elegant and fully adjustable option. A smooth slider bead with a rubber core runs along a box chain, allowing you to adjust the fit continuously without needing an extension chain. It takes a little practice to get used to, but once you have the knack it's very easy to use.

Pro: Fully adjustable and elegant in finish.
Con: On smaller wrists, the excess chain may dangle.
Cost: Approximately £6 more than a medium trigger clasp.

Elasticated

Of course, you could skip the clasp altogether and go elastic! It's the easiest to put on and take off, and the most budget-friendly option. The elastic is knotted and glued securely — with the right care it will last for years, though it won't last forever.

Pro: Easiest to use; most affordable option.
Con: The elastic will eventually loosen over time.
Cost: Approximately £4 less than a medium trigger clasp.
