Clasps & Closures

Clasps & Closures

How every earring back and every necklace or bracelet clasp works—and how to open and close each one with ease.

Every product page lists the closure of that piece. Here is how each one works, so you know what to expect before you order—and how to fasten it without forcing anything.

Earring closures

Hinged Clicker
Open the hinge, pass the post through, and press until it clicks.
Hinged Snap Closure
Open at the hinge, pass the post through, and press until it snaps shut.
Butterfly Back
Push the post through, then slide the butterfly back on until snug.
Screw Back
Turn the back clockwise onto the threaded post until snug; turn counterclockwise to remove.
Omega Back
Pass the post through, then close the hinged clip onto it behind your ear.
Lever Back
Open the hinged lever, pass the wire through, and press the lever closed.

Necklace & bracelet clasps

Lobster Clasp
Pull the small lever to open the claw, hook it through the ring, then let go.
Spring Ring Clasp
Pull the small tab back to open the ring, slip the jump ring in, then release.
Box Clasp
Press the tongue and slide it into the box until it clicks, then close the safety latch. Used on tennis styles.
Fold-Over Clasp
Lift the lever, fit it over the bar and press it flat until it snaps shut.

What you should know

Earring closures

  • Hinged clicker — the hinge swings open, the post passes through and the clicker presses shut. Fast to put on and secure.
  • Hinged snap closure — similar to a clicker, closing with a firm snap. Common on larger hoops.
  • Butterfly back — a classic push-on back that slides onto the post until snug.
  • Screw back — the back twists onto a threaded post. Takes a few seconds longer but holds very securely.
  • Omega back — a hinged clip that closes over the post behind the ear and supports larger studs.
  • Lever back — a hinged lever closes over the ear wire.

Necklace & bracelet clasps

  • Lobster clasp — pull the small lever to open the claw, hook it through the ring and let go.
  • Spring ring clasp — pull the tab back to open the ring, slip the jump ring in and release.
  • Box clasp — press the tongue, slide it into the box until it clicks and close the safety latch. Used on tennis styles.
  • Fold-over clasp — lift the lever, fit it over the bar and press it flat until it snaps.

Tips for fastening on your own

  • Fasten a necklace in front of you, then turn the chain so the clasp sits at the back.
  • For bracelets, rest your wrist on a table and hold the clasp end steady with your other hand.
  • On tennis bracelets, always close the safety latch—it keeps the bracelet on if the box clasp is knocked open.

Taking care of closures

Open and close hinges gently, without twisting. Don’t bend posts or force a closure that does not close easily. Check closures and stone settings before wearing, and contact us if anything feels loose.

FAQ

Which earring back is the most secure?

Screw backs and hinged clickers hold very firmly. Butterfly backs are secure too; make sure they slide on until snug against the ear.

Which clasp is easiest to fasten by myself?

A lobster clasp is the easiest to use with one hand. Fasten it in front of you and turn the chain so the clasp sits at the back.

My clicker or snap closure won’t close. What should I do?

Don’t force it. Make sure the post is lined up with the opening and press gently. If it still won’t close, contact us with your order number.

What gauge are your earring posts?

Post thickness is listed on each product page. Many of our posts are 18G (1.0 mm) or 20G (0.8–0.9 mm).

Why does a tennis bracelet have a safety latch?

The latch is a second lock over the box clasp. It keeps the bracelet on your wrist if the clasp is pressed open by accident.
