Gold has always been a popular choice for jewelry, savings, and investment in India. But with rising prices and demand, cases of fraud and fake gold have also increased. Knowing how to check purity and authenticity can save you from heavy losses.


1. Check Hallmark & HUID Code

  • Hallmark: Every piece of gold jewelry should carry a hallmark from the Bureau of indian Standards (BIS), which guarantees quality.
  • HUID Code: A unique 6-digit alphanumeric code engraved on gold jewelry. It can be verified using the BIS Care App to ensure authenticity.


2. Verify Carat & Purity Numbering

  • 22 Carat Gold – Marked as 916
  • 18 Carat Gold – Marked as 750
  • 24 Carat Gold – Marked as 999
    Always match the carat number with the hallmark for additional assurance.


3. Quick home Tests to Detect Fake Gold

  • Water Test: Real gold sinks; fake gold may float.
  • Magnet Test: gold is non-magnetic; if it sticks, it’s adulterated.
  • Vinegar Test: A few drops won’t change the color of real gold, but fake gold may tarnish.
  • Rub Test: Rubbing on a surface leaves a yellow mark for real gold; fake gold leaves a dark mark.


4. Always Ask for a Bill

Ensure you get a proper bill with GST number. You can verify the GST number online to confirm the authenticity of the seller.


5. Use a Caratometer for Accurate Testing

Many jewelry stores have a caratometer machine that gives a precise reading of gold purity. Use it for extra assurance before finalizing your purchase.


Final Word

Whether buying gold for festivals like Dhanteras or as an investment, taking these precautions will ensure you bring home genuine gold – not glittering trouble.
