How to Tell If Sterling Silver Is Real: Free Testing in LA
Wondering whether your pieces are solid 925 sterling or just plated? Here is how to tell if sterling silver is real from its stamps and a few at-home tests, or bring it to our Lawndale showroom for expert, no-obligation testing.
How to Tell If Sterling Silver Is Real in Los Angeles
If you want to know how to tell if sterling silver is real, the most dependable answer in Los Angeles is to have it examined by people who handle it every day. South Bay Coin has authenticated and tested silver for South Bay families since 1980, and our appraisers can read a hallmark, recognize a fake stamp, and confirm purity in minutes.
The reason matters: solid sterling and silver plate can look identical to the naked eye, yet one is precious metal all the way through and the other is a thin silver skin over brass, copper or nickel. A discreet "925" stamp is the first clue, but counterfeit stamps exist, so a mark alone is never final proof. We confirm every piece with a non-destructive XRF analyzer that reads the silver content without scratching or damaging your item.
Whether you inherited a flatware service, found an unmarked chain in a drawer, or simply want to know what you own before you decide to sell sterling silver in Los Angeles, you can walk in for a private, no-pressure evaluation. We also test silver coins and mixed lots, and we explain exactly what your stamps mean and why.
Not everyone who asks is selling. Plenty of visitors from Torrance, Redondo Beach and Hawthorne bought a 925 chain online or at a swap meet and want to know whether it matches the listing. That is a complete visit too: you leave knowing what the piece is, and nothing else is expected.

Sterling Silver Stamps and Hallmarks to Look For
The fastest way to identify real sterling silver is to find its purity stamp. Marks are tiny and tucked into discreet spots: the inside of a ring band, the underside of a clasp, the back of a pendant, or the back of a silver flatware handle. A jeweler's loupe makes them far easier to read. On genuine sterling you will see 925, .925, S925, 92.5, STER, STERLING, or STERLING SILVER, all of which mean the metal is 92.5 percent pure silver throughout.
Other purity numbers are real silver too, just different standards. 999 is fine silver, 958 is Britannia, and 900 (coin silver), 835, and 800 are common on older German, Italian, and continental pieces. On British silver, look for the walking lion passant, the traditional symbol of the sterling standard. Under U.S. rules, a piece stamped "925" or "Sterling" should also carry a maker's mark identifying who made it, so a quality stamp standing entirely alone deserves a second look.
Just as important is knowing the marks that mean it is not solid silver. EPNS, EP, SP, and A1 all indicate silver plate, a base metal coated with a thin silver layer. On flatware, letters like IS are a maker's mark (International Silver Company), not a purity guarantee. Be wary of "925 Silver Plated," which is a contradiction, and of crisp 925 stamps on suspiciously light pieces. A counterfeit stamp is exactly why a final test matters.
How to Tell If Silver Is Real at Home
No stamp, or a stamp you do not trust? A few simple tests narrow things down before you visit an expert. The magnet test is the easiest: real silver is not magnetic, so if a strong magnet pulls toward your piece, it is not solid silver. Remember this test only rules silver out, since many fake metals are also non-magnetic.
The ice test is the most telling for flat items like flatware, trays, and coins. Silver has the highest thermal conductivity of any metal, so an ice cube placed on genuine silver melts noticeably faster than on steel or plate. Set a second cube on a stainless spoon at the same moment so you have something to compare against. The ring test works on coins and solid pieces: tap them gently and listen for a clear, sustained, high-pitched chime rather than a dull clunk.
Two more clues help. Real sterling tarnishes, so rubbing it with a soft white cloth often leaves a faint black mark. A piece that never darkens is not automatically fake, though, because much modern sterling jewelry is rhodium plated at the factory to resist tarnish, which also defeats the cloth test. Genuine silver is odorless; a strong metallic smell after handling points to a nickel or brass alloy.
Avoid bleach and acid tests at home, as both can permanently damage your piece. If a piece passes every home test, it is probably silver, but only a measurement tells you whether it is sterling, coin silver, or 800. For a definitive answer, our XRF analyzer reads exact purity without a scratch.

What Our Sterling Silver Customers Say
Questions About Identifying Real Sterling Silver
How can you tell if sterling silver is real?
To tell if sterling silver is real, start by looking for a purity stamp such as 925, .925, or Sterling in a discreet spot like a clasp or ring interior. Then confirm with simple tests: real silver is not magnetic, melts ice quickly, and tarnishes over time. For certainty, have it checked with a professional XRF analyzer.
What does 925 mean on silver?
A 925 stamp means the piece is sterling silver, an alloy of 92.5 percent pure silver and 7.5 percent other metals (usually copper) added for strength. The same standard appears as .925, S925, 92.5, or the word Sterling. It is the international mark for solid sterling silver throughout the piece.
What stamps are on real sterling silver?
Genuine sterling carries 925, .925, S925, 92.5, STER, STERLING, or STERLING SILVER. British pieces also show a walking lion (lion passant). Other real silver standards include 999 fine silver, 958 Britannia, and 900, 835, or 800 on older European silver. A maker's mark often appears alongside the purity stamp.
Does a magnet stick to real sterling silver?
No. Real silver is not magnetic, so if a strong magnet sticks or pulls toward your piece, it is not solid silver. Keep in mind the magnet test only rules silver out, since many fake metals like brass and copper are also non-magnetic. Always pair it with another test.
Does real sterling silver tarnish?
Yes. Real silver reacts with sulfur in the air and darkens over time, which is why rubbing it with a white cloth often leaves a black mark. The tarnish is harmless and does not need cleaning before a test. A piece that never tarnishes may be plated, fake, or genuine sterling with a factory rhodium finish.
What does EPNS mean on silver?
EPNS stands for Electro-Plated Nickel Silver, meaning a base metal coated with a thin layer of silver. It is not solid silver. The same goes for EP, SP, and A1 stamps. If you see these marks and no 925 or Sterling stamp, the piece is silver plated rather than sterling.
Is 800 or 900 silver real silver?
Yes, both are genuine silver, just at a lower purity than sterling. An 800 mark means 80 percent pure silver and 900 (often called coin silver) means 90 percent. These standards are common on older German, Italian, and continental pieces. They are real silver, simply different alloys than the 92.5 percent sterling standard.
How do you tell if sterling silver is real or plated?
To tell if sterling silver is real or plated, check the stamp first: 925 or Sterling means solid, while EPNS, EP, or SP means plated. Then inspect high-wear spots like clasps and edges, where plating wears through to show a different colored base metal underneath. Solid sterling is the same color throughout.
Can fake silver be stamped 925?
Yes. Counterfeiters routinely stamp fake 925 marks on plated or base-metal pieces, so a hallmark is a useful first clue but never final proof. Watch for crisp 925 stamps on suspiciously light items or "925 Silver Plated" labels. The only sure way to confirm purity is professional testing.
