Types of jewelry clasps (necklaces, bracelets and earrings)

A clasp joins the ends of a jewel or fastens an earring. It is one of the parts most used and most worn; it is worth choosing well.

Necklace and bracelet clasps #

• Lobster claw: a claw with a spring; very secure.
• Spring ring: a ring with a pin; common on fine chains.
• Toggle: a bar that crosses a ring; decorative.
• Box and tongue: a V tongue enters a box; usually has a safety.
• Barrel: two halves that screw together.
• Magnetic: closes with a magnet; convenient, not for heavy pieces.
• Fold-over (deployant): for watch bands and bangles.

Earring backs #

• Butterfly (push-back): a piece that slides onto the post.
• Screw-back: the post is threaded; more secure.
• Lever-back: a hinge that closes behind the ear.
• Clip-on: a clamp for unpierced ears.
• Latch and French clip: clasps built into the earring.

How to choose #

For heavy necklaces, a lobster claw or box with a safety; for heavy earrings, screw or lever back. Check them regularly.

How to choose a clasp #

• Heavy or valuable necklaces: lobster claw or box with a safety.
• Fine chains: spring ring.
• Bracelets you put on alone: toggle or magnetic.
• Pearls: box clasp, which holds the thread better.
• Drop or heavy earrings: screw or lever back.

What fails most often #

The lobster-claw spring loosens, the tongue of the box loses tension, and an earring butterfly stretches. Replace them before they fail: it is a cheap repair. See repairing a chain and professional maintenance.

Extra security #

Many box clasps have a figure-eight safety: a small piece that stops the tongue from slipping out. Highly recommended on valuable bracelets.
