Screw backs and locking backs are the most secure earring backs. Lever backs and hinged snap backs are secure too. Push backs, the most common, grip by friction and loosen with wear, so replace them when they slide easily. A bent post is usually straightened by a jeweler, and solid gold suits most sensitive ears.
Almost every lost earring is lost at the back. The front of an earring gets the attention, but the back decides whether it is still there at the end of the day, and for diamond studs that matters a great deal.
Earring backs compared
| Back | How it works | Security | Found on |
|---|---|---|---|
| Push back (butterfly) | Slides onto the post and grips by friction | Moderate; loosens with wear | Most studs |
| Screw back | Twists onto a threaded post | High | Diamond studs, children’s earrings |
| Locking back | A push back with a locking mechanism | Very high | Valuable and heavy studs |
| Lever back | A hinged loop that snaps closed over a hook | Good | Drops and dangles |
| Hinged snap back | Part of the hoop swings shut and clicks | Good | Hoops and huggies |
| Latch back | A post clicks into a latch | Fair to good; latch can wear | Hoops |
| Fish hook | An open hook through the ear | Low without a stopper | Drops |

Push backs: why they loosen
The push back is the standard stud back because it is quick and easy. It works by two small curls of metal gripping the post. With every removal they open slightly, and after enough months they no longer grip firmly. If a back slides on with almost no resistance, replace it. Backs are inexpensive, and a new pair is cheaper than a lost earring. For heavy studs or anything you would hate to lose, a screw back or locking back is the safer choice.
Screw backs and locking backs
A screw back threads onto a post with a fine spiral cut into it, so it cannot simply slide off. It takes a moment longer to put on and is the usual choice for valuable diamond studs. A locking back grips the post like a push back and then locks in place until you release it. Both are worth asking for on any stud with a diamond.
Hoops: snap backs and latch backs
Hoops usually close in one of two ways. A hinged snap back has a section of the hoop that swings open and clicks into the other side. A latch back has a post that slips into a small catch. Both are secure when the click is firm. If a hoop closes without a definite click, or opens when you squeeze it gently, the mechanism has worn and should be adjusted.
Why earring posts bend
Posts are thin, and gold is a relatively soft metal, so a post can bend if an earring is slept in, caught on a sweater or brush, or pushed in at an angle. A slightly bent post makes the back harder to fit and can let it slip off. Don’t try to bend it back repeatedly yourself, because metal that is bent back and forth weakens and can snap. A jeweler can straighten or replace a post quickly. Taking earrings out to sleep prevents most bending.
Gold for sensitive ears
Many earring reactions are a reaction to nickel, one of the most common causes of allergic skin irritation. Yellow gold is generally one of the safer choices for sensitive ears; some white gold alloys contain nickel and some do not, so ask if that matters to you. Plated earrings can cause a reaction once the plating wears through to the metal underneath. A solid gold post has no plating to wear away.

Earring backs FAQ
What is the most secure earring back?
Screw backs and locking backs. Lever backs and hinged snap backs are also secure.
Why do my earring backs keep falling off?
Push backs loosen with wear. If one slides on easily, replace it, or switch to a screw or locking back.
Can a bent earring post be fixed?
Yes. A jeweler can straighten or replace it. Avoid bending it back and forth yourself.
Are gold earrings good for sensitive ears?
Solid yellow gold is generally well tolerated. Some white gold contains nickel, a common allergen.
Should I sleep in my earrings?
It is better not to. Sleeping in earrings bends posts and loosens backs.
