What is an earring back?

Definition
An earring back is the small component that slides onto the post of a stud earring and holds it securely against the earlobe. The most common type is the scroll, also called a butterfly back or nut, which has two curved metal wings that grip the post through spring tension; pushing the wings together releases it. The friction or grip between the scroll and post is what stops the earring sliding off. Replacement scrolls in silver, gold and other metals are widely available since they are the part most often lost.
Frequently asked questions
- What are the different types of earring backs?
- The most common is the scroll or butterfly back, which pinches onto the post. Others include the push-back or friction back (a simpler clip without wings), the lever-back (a hinged loop used on drop earrings), the screw-back (which threads on for extra security) and the La Pousette (a flat spring push-back with a box housing).
- How do I stop earring backs from falling off?
- Make sure you are using backs sized to fit the post gauge of your earrings; a back intended for a thinner post will be loose on a thicker one. Locking or screw-back styles offer extra security for precious earrings.
- Can I replace lost earring backs?
- Yes, spare earring backs are inexpensive and easy to find in the right metal, whether sterling silver, gold-filled or solid gold. Match the metal to your earrings and check the post gauge so the new backs grip properly.
