You found a beautiful piece of silver jewelry online. The price looks fair, the photos look premium — but is it genuine sterling silver, or silver-plated brass that will wear through in months? This guide gives you the complete difference, and five practical checks to tell them apart before you spend a dollar.
The Quick Answer
Sterling silver (925) is solid silver throughout — an alloy of 92.5% pure silver and 7.5% copper for strength. Cut it in half and the inside is the same metal as the outside. Silver plated is base metal — usually brass, copper or zinc — coated with a silver layer typically 0.5 to 5 microns thick. For reference, a human hair is about 70 microns. Sterling silver lasts decades and can be re-polished forever; plating wears through in 1–3 years of regular wear and cannot be restored.
What Is 925 Sterling Silver?
Pure silver is too soft for daily-wear jewelry, so the global standard is 925: 92.5% pure silver alloyed with copper. Genuine sterling silver is always hallmarked — look for a tiny "925", "S925" or "Sterling" stamp on the clasp, the inside of a band, or the back of a pendant. It develops a natural patina over time, polishes back to full shine with a silver cloth, and is hypoallergenic for most people.
What Is Silver Plated?
Silver-plated jewelry is made by electroplating a microscopically thin silver layer onto base metal. It looks identical to sterling silver in a product photo. The difference shows up in months two and three: the plating wears through at contact points — clasp edges, chain links, ring bands — and the base metal underneath oxidises or reacts with your skin. Stamps like EP (electroplated), SP (silver plated) or EPNS (electroplated nickel silver) confirm a piece is plated, not sterling.
Sterling Silver vs Silver Plated: Side by Side
| 925 Sterling Silver | Silver Plated | |
| Composition | 92.5% silver throughout | Base metal + thin silver coating |
| Lifespan | Decades with basic care | 1–3 years of regular wear |
| Tarnish | Tarnishes gently, polishes back to full shine | Plating wears off — cannot be restored |
| Skin safety | Hypoallergenic for most people | Exposed base metal (often nickel) can cause reactions |
| Green skin marks | No | Yes, once copper/brass is exposed |
| Hallmark | 925 / S925 / Sterling | None, or EP / SP / EPNS |
| Resale value | Retains intrinsic silver value | None |
5 Ways to Tell the Difference Before You Buy
- Find the hallmark. No 925 stamp is the single biggest red flag. Reputable sellers hallmark every genuine piece and photograph the stamp.
- Check the price against reality. Silver has a real commodity price. A "sterling silver" statement necklace for $8 shipped is not sterling silver — the metal alone would cost more.
- Read the listing language word by word. "Silver tone," "silver color," "silver finish" and "silver look" are legal ways of saying not silver. Only "925," "sterling silver" or "solid silver" mean the real thing.
- Look for a material breakdown. Honest sellers state the base metal when a piece is plated. If the listing avoids naming any metal at all, assume plated.
- Check the seller's tarnish policy. A brand confident in real silver will tell you it tarnishes gently and polishes back. A plated-jewelry seller stays quiet, because plating doesn't tarnish — it disappears.
Already Own the Piece? 3 At-Home Tests
- The hallmark check. Examine the clasp and edges with your phone camera zoomed in. 925 confirms sterling; EP/SP/EPNS confirms plated.
- The magnet test. Silver is not magnetic. If a strong magnet grabs the piece, it contains ferrous base metal. (Passing alone doesn't prove silver — brass isn't magnetic either — but failing disproves it.)
- The polish test. Rub gently with a silver polishing cloth. Sterling silver leaves faint grey-black residue on the cloth and shines brighter. Plating shows no residue — and aggressive rubbing can actually remove it.
Why Real 925 Costs What It Costs
A genuine sterling silver charm carries real metal weight at commodity silver prices, plus hallmarking and hand-finishing. That is why authentic 925 charms typically sit in the $50–$100 range while visually identical plated versions sell for $5–$15. The plated piece is not a bargain version of the same product — it is a different product that happens to photograph the same.
Which One Should You Buy?
Both have a place. For pieces that touch your skin daily — charms, chains, everyday earrings — 925 sterling silver is worth it: hypoallergenic, restorable, and still beautiful in ten years. For occasional statement pieces worn a few times a year, honestly-labelled plated jewelry is a legitimate budget choice. The metal doesn't make jewelry good or bad — the honesty of the seller does.

FAQ
Is silver plated real silver?
The coating is real silver, but the piece is not — typically over 99% of the metal is brass, copper or zinc. Once the micron-thin coating wears through, what remains is base metal.
Is sterling silver better than silver plated?
For anything worn regularly, yes. Sterling silver lasts decades, polishes back to full shine, and is hypoallergenic. Plating wears through within 1–3 years and cannot be restored.
Does silver plated jewelry tarnish?
Not exactly — it wears. Sterling silver tarnishes (a surface reaction you can polish away). Plating physically abrades off, and there is no bringing it back.
How long does silver plated jewelry last?
With regular wear, typically 1–3 years before the plating wears through at contact points. Occasional wear can stretch that longer.
Does silver plated jewelry turn skin green?
Once the plating wears through, exposed copper or brass oxidises and can leave green marks on skin. Solid sterling silver does not do this.
What does 925 mean on jewelry?
92.5% pure silver — the international standard for sterling silver. See our full guide: What does 925 mean on a silver charm?
