You've probably seen '925' stamped inside a ring, near a necklace clasp, or on the back of a pair of earrings. However, it's not always obvious what that tiny number actually means. 925 sterling silver is made with 92.5% pure silver and 7.5% other metals, most commonly copper, which gives it the strength to hold its shape through everyday wear. So when you see '925' on a piece, it's telling you about the metal underneath not just the finish you see on the outside.
The balance is exactly why sterling silver shows up in so many pieces people reach for everyday. It still has the look and feel of a precious metal, but it's practical enough for rings, earrings, necklaces, clasps, and stone settings. If you've ever wondered what '925' really means or whether sterling silver can actually keep up with everyday wear, here's what to know about how it wears, why it tarnishes, and how to care for it.
What Does the 925 Stamp Actually Mean?
The '925' mark refers to silver fineness: 925 parts out of 1,000 are pure silver, while the remaining 75 parts are usually another metal added for strength. Pure silver is naturally soft, which makes it less practical for jewelry that has to hold a stone, keep a clasp secure, or stand up to regular wear.
You'll usually find the 925 stamp somewhere discreet, inside a ring, on an earring post, or near a necklace clasp. Think of it as a small clue to what the piece is actually made of, rather than just the color or finish you see on the surface.
The 925 hallmark is a small detail that tells you the piece is sterling silver, not just silver-colored on the surface.
925 Sterling Silver vs. Silver-Plated Jewelry
The biggest difference is what the piece is made of underneath. With 925 sterling silver, the metal itself contains 92.5% silver. By contrast, silver-plated jewelry usually has a different base metal covered with a thin layer of silver or a silver-colored finish.
That difference tends to show up with wear. A plated finish can gradually fade or rub away, especially on pieces you reach for often, while sterling silver can usually be cleaned and polished because the silver is part of the metal itself, not just the surface.

Does 925 Sterling Silver Tarnish?
Yes, 925 sterling silver can tarnish, especially if it's a piece you wear often. Everyday things like perfume, skincare, humidity, and even the air can gradually darken the surface of silver. This doesn’t mean the piece is ruined, Tarnish is usually just a surface reaction, and a soft polishing cloth can often bring the shine back. Keeping your jewelry dry and storing it away from cosmetics and chemicals can also help slow it down.
What About Gold-Plated Sterling Silver?
Sterling silver can also be finished with a layer of gold or rhodium, giving the piece a different color while keeping a 925 silver base underneath. Because plating sits on the surface, it can gradually change with friction, moisture, and regular wear, so the quality of the finish matters.
At ALEXCRAFT, selected plated pieces use a 0.1 finish and undergo a 48-hour corrosion test as part of our quality checks. These details give a clear picture of how a piece is made and tested, rather than relying only on broad claims like 'long-lasting'.

How to Care for 925 Sterling Silver
A little routine care goes a long way with sterling silver. Give your jewelry a quick wipe with a soft polishing cloth after wear, make sure it's dry before storing, and try to keep perfume, lotion, chlorine, and household cleaners away from the surface. If your piece is plated, skip aggressive polishing or harsh cleaners, since they can wear down the finish over time. Storing jewelry separately in a pouch or jewelry box also helps prevent scratches and slow tarnish. For a fuller routine, see our everyday jewelry care guide.

Frequently Asked Questions
Is 925 sterling silver real silver?
Yes. 925 sterling silver is made with 92.5% pure silver and 7.5% other metals, usually added for strength. The '925' mark refers to the silver content of the metal itself.
Will 925 sterling silver tarnish?
It can. Tarnish is a normal surface reaction that develops over time, especially with exposure to humidity, skincare, perfume, and certain chemicals. It can usually be removed with gentle polishing and proper care.
Is sterling silver good for sensitive ears?
It can be a good option, but the full material composition still matters. If you have sensitive ears, look beyond the '925' label and check the alloy, earring post material, plating, and any available nickel-release testing.
At ALEXCRAFT, an applicable gold-plated metal sample was independently tested by SGS for nickel release in reference to EN 1811:2023 and passed the relevant REACH requirement, with nickel release not detected in all three test trials. We use third-party testing like this to give you more than just a “hypoallergenic” label.
Can I wear 925 sterling silver every day?
Yes, sterling silver is durable enough for regular wear, which is one reason it is widely used for rings, earrings, necklaces, and stone-set jewelry. Like any jewelry, though, how it looks over time depends on friction, moisture, chemicals, and how it is cared for.
Can I shower with sterling silver jewelry?
Occasional contact with clean water does not automatically ruin sterling silver, but repeated exposure to chlorine, salt water, soaps, and personal-care products can speed up tarnish or affect plated finishes. Taking jewelry off before swimming or prolonged water exposure is the safer habit.
How can you tell if sterling silver jewelry is good quality?
Start with clear material information. Look for a 925 mark, disclosure of the base metal and any plating, and specific construction or testing details where available. Clear specifications usually tell you more than broad claims such as “premium” or “high quality.”
Final Note
Once you know what the 925 mark means, sterling silver becomes much easier to shop for. It offers the look and feel of a precious metal with the durability needed for pieces you’ll reach for often, and a little routine care can help keep it looking its best over time.
