How to Repair a Necklace Clasp
Replace a broken clasp yourself at home. (necklace image by Byron Moore from

The majority of necklaces are held in place by a clasp. There are many kinds of clasps, including box, lobster claw, toggle, slide lock, hook and eye, magnetic and S-hook. Most of the time, clasps last indefinitely, especially when they are made of quality materials. But occasionally, a clasp will break or be lost altogether. This doesn't mean the necklace has to be remade or thrown out; you merely need to repair or replace the clasp. Replacing a clasp yourself saves the cost of a professional repair.

Skill level:

Things you need

  • Open-end jump rings
  • Flat-nosed pliers
  • Clasp of choice

  1. 1

    Bend a jump ring open with a pair of flat-nosed pliers.

  2. 2

    Slide the jump ring though the end of the necklace. Most clasps will be held in place by a crimp of some sort that has a hole for the jump ring.

  3. 3

    Slide the first half of the clasp onto the jump ring.

  4. 4

    Pinch the jump ring closed with the flat-nosed pliers.

  5. 5

    Repeat all steps on the other end of the necklace.

Tips and warnings

  • It is a good idea to replace all jump rings when you replace a clasp. Inspect the holes in the crimps on the necklace ends to make sure there is no breakage before attempting to replace a clasp.
