How to Open or Close a Fish Hook Clasp

Last Updated: October 28, 2019

Fish hook clasps can be tricky to undo if you aren't familiar with them. They are commonly found on pearl necklaces. They consist of an oval-shaped element (the "fish") and a "hook" which is mostly concealed in the clasp, making it tricky to figure out. However, once you've done it a few times, it's easy! Note, however, that they may prove difficult for those that suffer from arthritis or similar conditions that limit movement of the hand.

Method 1 of 2:

Opening a Clasp

1
Find a necklace with a clasp on it that looks like the above image, or similar.
- Note that the necklace pictured above is of considerable age and the clasp is a bit tarnished. Fish hook clasps can look slightly different from this example.
2
Hold the fish end in your non-dominant hand. A flat side should face you, and your thumb and finger should hold both narrow sides.

Hold the clasp and squeeze the narrow sides, where your fingers are, as shown above.^{[1]

- As you're doing this, push the hook end back into the fish until you feel it loosen, and then pull it out.

The clasp should now be halfway open, like this.^{[2]

- Feed the pointy end of the hook around the metal bar so that it looks like this:

The fish and hook end should look as they do in the above image, so that the hook can slide straight back into the fish.
4
Slide the hook straight back into the fish. You might hear a small click, or feel the end of the hook lock in place.^{[4]

The clasp is now closed, and you're ready for a fancy night out. A closed clasp should look like the picture in the introduction.

Question

I thread the hook into the top open section of the fish, hook it and push it down, but the top part of it does not go in. Any ideas

Make sure the hook is going all the way down. Some clasps will only close completely in one direction. In other words, take out the hook, turn it 180 and insert back into clasp. It should slide and click shut.
Question

Where are the gold markings on the clasp?

Top Answerer

Markings on jewelry are usually stamped in very small letters on the side opposite the design. Gold can be marked with a number and letter or with a three digit number. The numbers are very small and are often stamped on the wide link next to the clasp.

Warnings

Stubborn clasps that won't open should be taken to a jeweler. Attempting to fix the problem yourself may damage the necklace.
