How to Tell Real 925 Sterling Silver From Fake: 5 Tests That Actually Work
Sterling silver is one of the most faked materials in jewelry, because it sits in an awkward price band: expensive enough to matter, cheap enough that a plated copy can triple the seller’s margin. Here is how we check pieces ourselves when we buy stock — the same five tests you can run at home.
1. The stamp test (start here)
Real sterling is almost always stamped: 925, S925, Sterling or Sterling Silver, usually on the clasp, the inside of a ring band, or a small tag plate. The stamp is not proof by itself (stamps can be faked), but its absence on a piece sold as sterling is an immediate red flag.
Every piece we sell is stamped S925 — you can see it in the product photos, for example on the Sterling Silver Snake Chain Necklace clasp or inside the Sterling Silver Everyday Ring.
2. The magnet test
Silver is not magnetic. Hold a strong fridge magnet (ideally a neodymium one) to the clasp and the chain. If anything pulls, the core metal is steel or nickel — plated, not sterling. Note: springs inside clasps are sometimes steel even on genuine pieces, so test the chain and the band, not just the clasp mechanism.
3. The tarnish paradox
This is the test most buyers get backwards. Real silver tarnishes. A piece worn for months that shows a soft yellow-grey patina is behaving like sterling. The suspicious piece is the one that stays mirror-bright for a year — that is plating, or a stainless alloy sold under a silver name.
Tarnish is not damage: it wipes off with a polishing cloth in seconds. Our care guide covers the two-minute routine.
4. Weight and temperature
Silver is dense and conducts heat fast. A sterling piece feels cool against the skin for the first few seconds and noticeably heavier than the same volume of aluminum or hollow-plated alloy. Compare a minimalist earring against a fashion pair of the same size — the difference is obvious in the hand.
5. The price sanity check
Silver has a public commodity price. A “sterling” chain sold for $8 cannot be sterling — the raw metal alone costs more. You do not need to track spot prices: as a rule of thumb, genuine sterling earrings start around $25–40, chains around $50+, and anything dramatically below that is plated base metal, whatever the listing claims.

The one claim that should end the conversation
“Never tarnishes, waterproof, wear it in the shower forever.” No sterling silver seller who understands the material will say this. Silver is durable and shower-adjacent life is fine, but anyone promising a lifetime of zero care is describing a different metal. We’d rather tell you the truth and keep you as a customer for years — see how we work.
Quick checklist before you pay
- Stamp present (925 / S925 / Sterling)
- No magnetic pull on chain or band
- Seller can say in one sentence what the metal is
- Price is not impossibly low
- Return policy exists and is written down
Five checks, thirty seconds, and the fakes mostly eliminate themselves.
