A “925” stamp is easy to fake. Anyone with a cheap steel punch can press it into plated brass in a few seconds. So the stamp on its own does not prove much. To identify real 925 sterling silver jewellery, you need to check a few things together: the hallmark, the weight, the finish, and how the seller describes the piece. This guide covers all of them. It is written for buyers in India, where the fakes on the market are often not the ones the internet warns you about.
For buyers in India, checking a silver piece is not only about looking for “925”. You should know what a proper hallmark means, how HUID verification works, and what information a trustworthy online listing should provide.
Sterling silver is 92.5% pure silver and 7.5% other metal. That other metal is usually copper. This is all the number “925” means. Pure silver on its own is too soft. It bends easily and cannot hold a clasp or a sharp design. The small amount of copper makes it strong enough to wear every day, and it still keeps silver’s bright shine.
Jewellers measure silver purity in parts per thousand. They call this fineness. The main grades are:
| Mark | Meaning | Common Use |
|---|---|---|
| 999 | 99.9% silver | Fine silver |
| 925 | 92.5% silver | Sterling silver jewellery |
| 958 | 95.8% silver | Britannia silver |
| 835 | 83.5% silver | Some older or European pieces |
| 800 | 80% silver | Some older or imported pieces |
You may also see markings such as “S925”, “.925” or “STG” on jewellery. These are commonly associated with sterling silver, but the marking itself should not be treated as independent proof of authenticity.
In India, a BIS hallmark is an important purity and authenticity signal for hallmarked jewellery. It is also one of the most misunderstood parts of buying silver jewellery. Silver does not work exactly like gold here, and this is where many general jewellery guides become confusing.
In September 2025, BIS updated its silver rule to IS 2112:2025. Under the current framework, a silver hallmark has three parts:
The revised rule covers seven grades: 800, 835, 925, 958, 970, 990 and 999. An older hallmarked piece may look different because the earlier hallmarking framework was different.
Read the official PIB information on silver hallmarking
Under the current framework, silver hallmarking is voluntary.
That means a genuine silver piece may not carry a BIS hallmark. So a missing hallmark does not automatically mean a piece is fake.
At the same time, a plain “925” stamp is not the same thing as a BIS hallmark. A plain “925” is a purity claim, while a BIS hallmark provides an additional verification route.
If a piece is hallmarked and carries a HUID, you can verify the identification number using the BIS Care App. BIS provides a Verify HUID feature for applicable hallmarked jewellery.
Check the official BIS Care App information
For applicable hallmarked silver jewellery, verification can provide details such as article type, purity grade, hallmarking date, Assaying & Hallmarking Centre information and jeweller registration details.
If the details do not match the jewellery or the seller’s documentation, ask the seller for clarification before completing the purchase.
HS925 states that its applicable 92.5 sterling silver jewellery is BIS hallmarked and provides HUID verification information for hallmarked pieces.
| What You See | What It Means |
|---|---|
| 925 stamp only | A claim that the jewellery contains 92.5% silver; the stamp alone does not independently verify the claim. |
| BIS mark with SILVER and purity grade | Indicates that the article carries the applicable BIS silver hallmark format. |
| HUID | A unique identification code that can be verified through the BIS system for applicable hallmarked jewellery. |
| No purity information | Ask the seller to clearly state the metal and purity before buying. |
The important point is simple: a plain “925” stamp and a BIS hallmark are not the same thing.
You will find many home tests online. Some help a little. Some can damage your jewellery. It is worth knowing the difference before you try them.
One common source of confusion is “German silver”, also called nickel silver. Despite the name, German silver does not mean that the material contains 92.5% silver. It is an alloy typically involving metals such as copper, nickel and zinc.
It can look bright and silvery, which is why buyers sometimes assume it is real silver.
German silver may also pass the magnet test because it is not strongly magnetic. That means the magnet test alone cannot identify it.
If a seller calls a piece “silver”, the price looks unusually low, and the product has no clear purity information or other supporting documentation, ask questions before buying.

These two should not be treated as the same thing. They can look similar when new, but the material underneath is different.
The jewellery itself is made from an alloy containing 92.5% silver.
A thin layer of silver is applied over another base metal.
| Feature | 925 Sterling Silver | Silver-Plated Jewellery |
|---|---|---|
| Silver content | 92.5% silver alloy | A thin silver layer over another base material |
| Base material | Sterling silver alloy | Usually another metal |
| Purity description | 925 or 92.5% sterling silver | Should be clearly described as plated |
| Surface wear | Silver is part of the jewellery material | The plating can wear over time |
Silver-plated jewellery is not automatically poor quality. The important thing is that the product is described honestly so you know what you are buying.
Gold-plated 925 silver is different from gold-plated base metal.
In this case, the underlying jewellery is sterling silver, while the outer surface has a gold finish.
So a product can correctly be described as gold-plated 925 sterling silver.
The key is that the product description should clearly state both the underlying metal and the finish.
A gold-coloured jewellery piece is not automatically gold, and a gold-plated piece is not automatically solid gold.
When you buy online, you cannot feel the weight or inspect the jewellery in your hands. So the listing itself has to give you useful information.
Look for a clear purity of 92.5 or 925, hallmark information where applicable, HUID information where applicable, the weight in grams, and a clear note about any plating or surface finish.
A proper return window matters too. It gives you a way to address the situation if the piece arrives and does not match the description.
Read the metal line carefully. “Silver-plated”, “silver-toned”, “German silver” and “silver-look” do not mean the same thing as 925 sterling silver.
When reviewing an HS925 925 silver product, check the product page for the stated silver purity, hallmark information, HUID details where applicable, product weight, finish and care instructions. These details help you understand exactly what you are buying rather than relying only on the product name or a “925” stamp.

Real 925 sterling silver can tarnish over time. Tarnishing does not automatically mean that the jewellery is fake. Silver reacts with moisture, sweat, air and certain chemicals.
Remove silver jewellery before swimming, bathing or activities that expose it to excessive moisture.
Perfume, hairspray, lotions and cleaning chemicals can affect silver and surface finishes.
Keep jewellery in a dry pouch or suitable jewellery box to reduce scratching, tangling and unnecessary exposure to air and moisture.
Use a soft jewellery cloth and follow the care instructions provided for the specific piece.
If your 925 silver jewellery has a gold-plated or other surface finish, avoid aggressive polishing because it can affect the outer layer.
Before you pay, run through this:
No single home test proves authenticity on its own. The more reliable approach is to combine official hallmark or HUID information where applicable, clear product documentation, seller transparency and professional testing when necessary.
To identify real 925 sterling silver jewellery, do not trust just one sign. A stamp can be copied. A hallmark can provide an additional verification route. Weight can be measured. A seller’s words can be checked. Product specifications can be compared.
Understand what 925 means. Check the hallmark information where available. For a hallmarked item carrying a HUID, use the BIS Care App to verify it. Read the product description carefully and make sure the seller tells you whether the piece is sterling silver, silver-plated, gold-plated over silver, or another material.
For higher-value jewellery, professional testing is still the safest option when you have genuine doubts.
And when buying online, choose sellers that make the metal, purity, finish, weight, documentation and return terms clear.

Yes. 925 sterling silver means the alloy contains 92.5% silver, with the remaining portion made up of other metals.
No. Pure or fine silver is generally represented by a much higher fineness, such as 999. 925 sterling silver contains 92.5% silver and is commonly used for jewellery because it is more suitable for everyday construction.
No. A 925 stamp is a purity claim. It should be considered alongside other evidence such as hallmark information, seller documentation and, where applicable, HUID verification.
No. A 925 stamp is a purity claim, while a BIS hallmark is part of the formal hallmarking system. Where applicable, a current hallmarked silver article can also carry a HUID for verification.
Under the current BIS silver framework, HUID-based silver hallmarking was introduced on a voluntary basis from 1 September 2025. So the absence of a silver hallmark does not automatically mean an item is fake.
For hallmarked jewellery carrying a HUID, use the BIS Care App and its Verify HUID feature to check the applicable identification details.
Only partly. Silver is not magnetic, so a piece that sticks strongly to a magnet is a warning sign. But many fakes are also non-magnetic. Use the magnet test to spot some fakes, not to confirm silver.
They are not the same material. 925 silver contains 92.5% silver. German silver, also called nickel silver, is a different alloy and does not mean that the jewellery contains 92.5% silver.
It can be. “Gold-plated” describes the outer finish, while “925” describes the underlying silver alloy. A correctly described product can therefore be gold-plated 925 sterling silver.
Yes. Tarnishing is a normal reaction of silver with substances in its environment and does not automatically indicate that the jewellery is fake.
