How to Check Silver Purity Before Buying Jewellery
To check silver purity, begin with the stated fineness, inspect markings, retain the invoice and verify any hallmark claim through the applicable official route. A 925 stamp or a simple home test is not conclusive proof by itself. Unresolved questions deserve a professional assessment.
Start with a stated fineness
Look for an explicit material description, such as 925 sterling silver. The number refers to silver content: 925 parts per thousand, or 92.5%.
Words such as “silver colour” or “silver finish” do not establish the base metal. Read beyond the title to check whether the piece is sterling silver, silver-plated or simply silver-toned.
Understand what a stamp can and cannot prove
A 925 mark is a fineness claim. It should not automatically be treated as independent proof of the material or as equivalent to a complete BIS hallmark.
If a seller claims BIS hallmarking, ask what verification applies to that particular article. Consult current BIS hallmarking information rather than assuming that every stamped item has passed the same process.
Keep the invoice and the product description. Clear records connect the item you receive with the material the retailer said it was selling.
Avoid relying on home shortcuts
A magnet, sound, colour or tarnish test cannot precisely establish silver purity. A non-magnetic result does not confirm 925 silver, and darkening alone does not prove authenticity.
Do not scratch a new piece or apply acids, bleach or abrasive substances in an attempt to test it. You may damage plating, stones or the jewellery itself without reaching a reliable conclusion.
If there is a genuine concern, ask a qualified professional about suitable testing for the item's construction. Surface coatings can affect how some tests are interpreted; let the professional assess the method.
A useful purchase checklist
Before paying, confirm the base metal, any plating, the stone description and the retailer's process for material-related queries. Save those details with your order confirmation.
A non-destructive checking sequence
| Step | What to do | What it establishes |
|---|---|---|
| Read the listing | Find base metal and fineness | The seller's stated claim |
| Inspect marks | Use good light or a loupe | What markings are actually present |
| Keep documentation | Save invoice and product details | A record of the purchase |
| Verify a hallmark claim | Use the applicable BIS guidance | The relevant verification route |
| Resolve uncertainty | Consult a qualified professional | A suitable assessment of the piece |
A 925 stamp is useful information, but a stamp alone is not independent proof. Likewise, a piece that does not react strongly to a magnet has not thereby been proven to be silver. Different metals can behave similarly in simple home tests.
What to send the seller
Take a clear photograph of the whole piece and another of the marking, without filters. Include the order reference and quote the exact material wording you relied on. Ask whether the mark relates to silver fineness, a maker's mark or a formal hallmark, and what evidence supports the claim.
Keep the request specific. “Please confirm the base metal and fineness for this item” is easier to resolve than “Is this good quality?” If a hallmark is advertised, ask which system applies and follow current official instructions. Hallmark rules can change; this guide does not treat a product-name suffix or generic certificate image as verification.
The Ratniva edit
The Solitaire Shine listing states both 925 silver and a rhodium finish. Use those written claims as the starting point for your questions, then retain the order documentation. A catalogue description is not a substitute for independent testing.

Questions, answered
Does every 925 stamp guarantee authenticity?
No. A stamp is one piece of information, and its credibility depends on the supporting evidence and seller.
Can I test purity using only a magnet?
No. A magnet cannot measure silver fineness.
Should I damage the surface to test it?
No. Seek suitable professional advice if you need verification.
Read Ratniva's silver information, then explore the collection with greater confidence about the questions that matter.
Should I use an acid test at home?
No. It can damage a finish and involves chemicals that are inappropriate for casual checking. A jeweller or testing professional can explain a suitable method and its limitations. Until then, preserve the piece and the documentation so there is a clear record of what you received.
