How to Ascertain Gold Purity Before Purchasing — Even Online

Buying gold online can be convenient — but it also requires caution. Unlike an offline jeweller where you can inspect the piece in hand, online purchases depend heavily on the seller’s honesty and transparency.

Here’s how you can make sure the gold you buy online is real, pure, and protected by law.

1.  Look for the BIS Hallmark

In India, it’s now mandatory for gold jewellery to be BIS hallmarked with HUID. This ensures the piece has been verified by the Bureau of Indian Standards.

Every BIS hallmark includes:

• The BIS logo
• The purity grade — like 22K916 (91.6% pure)
• A unique 6-digit HUID number

2. Check for the HUID Number

The Hallmark Unique Identification (HUID) is a 6-digit code laser-inscribed on every hallmarked piece of gold jewellery.

This number links back to BIS records and can help trace the source of the jewelry. If a seller displays the HUID number in the product description or invoice — that’s a great sign of authenticity.

3.  Ask the Right Questions

If you’re shopping via WhatsApp, Instagram, or small independent websites — don’t hesitate to ask:

• “Is this BIS Hallmarked?”
• “Can you show the HUID in a photo or video?”

Honest sellers will always comply — fraudsters usually dodge.

4.  Test It After Delivery (If Needed)

Still unsure? You can get the gold tested at a BIS-recognized testing centre or a trusted local jeweller. Many sellers also allow returns if you raise concerns within a few days.

Tip: Always record your unboxing — it can help resolve disputes later.

 Conclusion

Gold purity is too important to guess. Whether buying online or offline, always look for BIS hallmarks, HUID numbers, and transparent sellers who stand behind their products.

Shop smart. Ask questions. Protect your investment.
