5 min read
Learn red flags that indicate counterfeit jewellery and how to verify authenticity before buying.
Counterfeit jewellery is a real problem. Here's how to protect yourself by identifying red flags and verifying authenticity.
Red Flags for Fake Jewellery
Missing or Unclear Hallmarks
- Real precious metal jewellery is hallmarked
- Hallmarks should be clear, not faint or scratched
- Absence of hallmarks is often a sign of lower quality or fake pieces
- Look for clear purity markings (916, 750, 925)
- Verify the BIS logo is present
- Check the assaying centre's mark
- Research the centre — it should be listed on the BIS website
- **Acid testing** for gold purity
- **Specific gravity testing** for gemstones
- **X-ray fluorescence** for metal composition
Suspiciously Low Prices
If a 22K gold piece costs the same as junk jewellery, something's wrong. Real gold costs significantly more.
Weight Inconsistencies
Real 22K gold feels substantial. If a piece feels light or hollow for its size, it might be fake or lower karat.
Color Inconsistency
Real gold is consistent in color. Fake pieces often show plating wearing off, revealing a different color underneath.
Verification Methods
Check the Hallmark
Request a Certificate
For diamonds and expensive pieces, demand a certificate of authenticity from a recognized lab (GIA, IGI, or AGS for diamonds).
Professional Testing
If you're unsure, ask a certified jeweller or gemologist to test the piece. Common tests include:
Buy From Verified Sellers
