What Is 925 Sterling Silver? The Complete Guide

Before you spend on silver jewelry, it helps to know exactly what you are buying. Here is what the "925" stamp means, how to tell real sterling silver from imitation, and why it is the standard for jewelry made to last.

925 sterling silver is an alloy of 92.5% pure silver and 7.5% other metals, usually copper. The "925" stamp is a hallmark certifying that purity. Pure silver on its own is too soft to hold a clasp or a stone, so that small amount of alloy gives sterling silver the strength to be worn every day, while keeping the bright, lasting shine silver is loved for.

What does "925" actually mean?

The number is a measure of purity. Sterling silver is 92.5% pure silver by weight, hence 925, blended with 7.5% of a harder metal, almost always copper. That ratio is not arbitrary: it is the internationally recognized standard for silver that is both beautiful and durable enough to wear. When you see 925, .925 or "sterling" stamped on a piece, you are looking at a hallmark that vouches for that composition.

The sterling standard: 92.5% silver, 7.5% alloy.

Is 925 sterling silver real silver?

Yes. 925 sterling silver is genuine silver; the "925" is precisely what certifies it. The distinction is worth getting clear, because it is where most confusion (and most buyer's remorse) comes from:

• Fine silver is 99.9% pure but too soft for everyday jewelry.
• Sterling silver (925) is real silver made wearable.
• Silver-plated jewelry is a base metal with a thin silver coating that wears off. It is not solid silver at all.

When a piece is hallmarked 925, you are buying real, solid silver throughout.

How to tell if your silver is genuine 925

A few quick checks separate the real thing from imitation:

• Look for the hallmark. Genuine sterling is stamped 925, .925, S925 or "STER", usually on a clasp, inner band or tag. (See How to Spot a Fake 925 Silver Hallmark for what a real stamp looks like.)
• Try the magnet test. Silver is not magnetic. If a piece pulls strongly to a magnet, it is largely base metal.
• Check for tarnish, not rust. Real silver may darken over time (tarnish), which polishes away. Plated pieces instead flake or discolor as the coating fails.
• Buy with a certificate. The simplest safeguard: every Paksha piece is hallmarked and comes with a certificate of authenticity, so the purity is not something you have to test for yourself.

Why 925 is the right choice for fine jewelry

Sterling silver sits in a rare sweet spot. It has the weight, shine and feel of a precious metal at a fraction of the cost of gold, and unlike plated fashion jewelry, it is solid and built to last rather than to be replaced. Genuine 925 is also well tolerated by most people: the irritation often blamed on "silver" usually comes from nickel in cheap base-metal pieces. (If you have a known metal allergy, check the metal details on the product page.) Cared for simply, a sterling piece can be worn for decades and passed on, which is exactly why it is the metal of heirlooms.

925 sterling silver vs the alternatives

This is the line Paksha lives on: hallmarked 925 sterling silver, not silver-plated base metal. Many of our pieces carry a gold or rhodium finish for color, and the metal underneath is still solid 925. It is why a Paksha piece costs more than a fast-fashion equivalent, and why it is still wearable years later.

Keeping sterling silver looking new

Sterling is low-maintenance, not no-maintenance. Store it dry and away from air, take it off for showers, swimming and perfume, and give it an occasional wipe with a soft polishing cloth. Tarnish is normal and completely reversible; it is not a sign of fake silver. Our guide to cleaning and polishing silver at home covers the full routine.

Frequently asked questions

Is 925 sterling silver real silver?

Yes. 925 means the piece is 92.5% pure silver, mixed with 7.5% alloy (usually copper) for strength. The stamp is a hallmark certifying that it is genuine, solid silver, not plating.

Does 925 sterling silver tarnish?

It can, gradually, when exposed to air and moisture. Tarnish is surface-level and polishes away completely. It is a property of real silver, not a defect, and proper storage slows it down.

Is 925 silver good quality?

925 is the international standard for fine silver jewelry, the best balance of purity, durability and value. Higher purity (999) is actually too soft to wear well, which is why sterling, not fine silver, is used for jewelry.

Is sterling silver better than gold-plated jewelry?

For longevity, yes, when the gold-plated piece is brass or another base metal: the thin coating fades and there is nothing precious underneath. 925 sterling is solid silver throughout, so it keeps its value and can be re-polished for years.

Can you wear 925 sterling silver every day?

Yes, that is what it is made for. The alloy gives it the strength for daily wear. Just remove it for swimming, showering and heavy cleaning to keep it bright.

Is 925 silver hypoallergenic?

Genuine 925 is well tolerated by most people. Reactions usually trace back to nickel in cheap base-metal jewelry, not to sterling silver itself. If you have a known metal allergy, check the piece's metal details first.
