Quick answer
- Check hallmarks: 925 = sterling silver, 14k or 585 = 14 karat gold, 18k or 750 = 18 karat gold.
- Read seller feedback, return policy and full item description before buying earrings on eBay.
- Ask for close-up photos of stamps, posts and backs in natural light.
- Vague terms like "alloy" or "gold tone" usually mean plated base metal, which may contain nickel.
Buying earrings on eBay and other resale marketplaces can be a great way to find vintage pieces, discontinued designs and solid gold for less. It can also mean fakes, mislabeled metals and itchy ears. We're an independent guide with no affiliation with any marketplace. Here's how to read listings, decode hallmarks and protect yourself.
Why buy earrings on eBay or resale sites?
Resale marketplaces are full of jewelry that isn't sold new anymore: vintage clip-ons, estate gold, old designer collections and single earrings to replace a lost one. Prices can be good because sellers range from professional dealers to people clearing out a drawer.
That variety is also the risk. Sellers may not know what they have, or may know and not say. Your job is to read listings like a jeweler would.
Decoding hallmarks and metal stamps
Hallmarks are the small stamps that indicate metal content. They're your first clue, though stamps can be faked, so treat them as evidence rather than proof.
| Stamp | Means | Notes |
|---|---|---|
| 925 or STER | Sterling silver, 92.5% silver | Can tarnish; usually fine for most ears |
| 10k or 417 | 10 karat gold, about 41.7% gold | Durable, more alloy |
| 14k or 585 | 14 karat gold, about 58.5% gold | A popular choice for everyday earrings |
| 18k or 750 | 18 karat gold, 75% gold | Richer color, softer |
| PT or PT950 | Platinum | Heavy, hypoallergenic for most people |
| GF or 1/20 GF | Gold-filled | Thick gold layer over base metal |
| GP, GE, HGE, RGP | Gold-plated or electroplated | Thin layer; wears off |
Earring posts are thin, so a stamp may be on the back, the clip or the backing instead. Some genuine vintage pieces aren't stamped at all; that's where seller reputation and testing come in.
Checking the seller and listing
- Feedback: look at recent feedback for jewelry specifically, not just overall percentage.
- Returns: prefer listings with clear return policies, and know the platform's buyer protection terms.
- Description: exact metal, weight in grams, measurements and condition notes are good signs.
- Language: "gold tone," "silver color," "alloy" or "looks like" usually means plated base metal.
- Stock photos: be careful with listings that only use catalog images.
- Questions: message the seller. A quick, specific answer is reassuring.
Ask for three photos before buying anything pricey: the hallmark up close, the post and back, and the earring next to a ruler or coin. A US dime is 17.91 mm across, which makes a handy size check.
Weight is another useful detail. Sellers of genuine solid gold often list the weight in grams, because it reflects the metal's value. If a pair of "solid gold" hoops has no weight listed and the seller won't provide one, be cautious.
Spotting fakes and misdescribed jewelry
Designer earrings are heavily counterfeited, and "solid gold" is sometimes plated. Warning signs include brand-new designer pieces at a fraction of the usual price, many identical "authentic" items from one seller, blurry logos, uneven plating and stamps that look shallow or crooked.
For designer pieces, see our guides to Chanel earrings and Coach earrings for brand-specific style notes. For anything valuable, consider a professional authentication service or a local jeweler who can test the metal.
Nickel, sensitivity and hygiene
Nickel is one of the most common causes of earring reactions, and unlabeled base metals often contain it. If your ears are sensitive, stick to stamped sterling, solid 14k gold or higher, platinum, or titanium posts, or plan to swap hooks for hypoallergenic ones.
- Clean pre-owned earrings with mild soap and warm water, then dry well.
- Wipe posts with isopropyl alcohol before wearing.
- Replace old backs with new ones; they're cheap and more hygienic.
- Skip pre-owned jewelry for fresh piercings; a professional piercer should handle starter jewelry.
If pre-owned earrings smell or itch, our guide to smelly earrings explains why. See a doctor if your ear shows signs of infection.
Sizing earrings from a listing
Size is one of the hardest things to judge from photos. Look for listings that give measurements in millimeters, and ask if they don't. Remember that 1 mm is about 0.039 inches, so a 10 mm stud is roughly 0.39 inches across.
For studs, compare the measurement with our 5mm actual-size guide or the earring size tool. For hoops, check whether the seller is giving inner or outer diameter, and the wire thickness. For dangles, ask for the total drop length from the top of the hook.
Smart things to buy secondhand
Some earrings are especially good resale finds: vintage clip-ons, plain solid gold hoops and studs, sterling statement pieces and single replacement earrings. Mixed lots can be fun for building a mismatched ear, just check every post before it goes near your skin.
