A tiny stamp, a real answer about what you're wearing.

This guide explains what the "925" stamp means in general, so you know what to look for and ask about wherever you shop. For material details on a specific North & Pearl piece, always check that product's own page, since composition is confirmed per item rather than assumed.
Quick Answer: What Does 925 Mean on Jewelry?
"925" is a purity stamp meaning the metal is sterling silver — 92.5% pure silver alloyed with 7.5% other metals (usually copper), which adds strength and durability that pure silver alone doesn't have. It's an internationally recognized hallmark, not a brand name or model number.
Key Takeaways
- 925 = sterling silver, standardized at 92.5% pure silver by weight.
- Pure (fine) silver is too soft for everyday jewelry on its own, which is why sterling silver uses an alloy.
- The stamp is usually found on the inside of a ring band, the back of a pendant, or near a clasp.
- Not every stamped number is 925 — other common stamps mean different things, covered below.
Why 92.5%, Not 100%
Pure silver (sometimes called fine silver, or 999) is very soft — soft enough that everyday jewelry made from it would scratch, bend, and wear down quickly. Alloying it with a small amount of another metal, almost always copper, makes it significantly more durable while keeping the look and shine of silver. The 92.5% ratio has been used as a standard for centuries and is now recognized internationally, which is why the "925" stamp means the same thing almost anywhere in the world.
Other Common Jewelry Stamps
925 isn't the only stamp you'll come across. A few others worth knowing:
- 999 or "fine silver" — close to pure silver (99.9%), softer and less common in everyday jewelry.
- 10K, 14K, 18K — gold purity stamps, where the number reflects how many parts out of 24 are pure gold (14K is 14/24, or about 58.3% gold).
- GP or "gold plated" — a base metal with a thin layer of gold applied over the top, rather than a solid gold alloy throughout.
- No stamp at all — doesn't automatically mean a piece isn't genuine, but a missing or illegible stamp is a reasonable thing to ask a seller about directly.
When shopping anywhere, if the material isn't clearly stated on the listing itself, it's worth checking directly rather than assuming from the stamp alone or the price point.
Where to Find the Stamp
The stamp is usually small and easy to miss. Common places to check:
- The inside of a ring band
- The back of a pendant or charm
- Near the clasp on a bracelet or necklace
- The post or back of an earring
A jeweler's loupe or a phone camera's zoom can help if the stamp is too small to read comfortably with the naked eye.

Frequently Asked Questions
Does 925 mean the jewelry won't tarnish?
No — sterling silver can still tarnish over time, since the copper in the alloy reacts with air and moisture. See the Jewelry Care Guide for how to slow that down.
Is 925 silver hypoallergenic?
Sterling silver is generally well-tolerated, but the copper content means it's not guaranteed hypoallergenic for everyone — people with a known metal sensitivity should check with the specific seller about exact composition before buying.
Can the 925 stamp be faked?
Stamps alone aren't proof on their own, since they can be applied to non-sterling metal. A reputable seller's listing, receipt, or documentation is a more reliable way to confirm material than the stamp by itself.
Is sterling silver the same as silver-plated?
No — sterling silver is a solid silver alloy throughout, while silver-plated means a base metal has a thin silver layer applied over it. Silver-plated jewelry is generally more affordable but the plating can wear thin over time with everyday use.
