Updated BIS Hallmark Gold Purity Standards Every Buyer Should Know (2026)

Buying gold is not only about design or price - it is about knowing that what you buy is real and pure. Many people feel confused when they see different purity numbers, marks, or stamps on jewellery. Because of this confusion, some buyers end up paying more for gold that is not actually pure.

This is where BIS hallmarking helps. It proves that your gold has been tested and certified. If you plan to buy gold in India in 2026, learning how BIS hallmark works will help you check purity, avoid fraud, and spend your money with full confidence.

What Is BIS Hallmark?

BIS hallmark is a government certification that confirms the purity of gold or silver jewellery. It is issued by the Bureau of Indian Standards (BIS), the national standards authority of India.

When jewellery carries a BIS hallmark, it means:

✔ The metal purity is verified
✔ The jewellery meets Indian standards
✔ You are paying for genuine gold or silver

Without hallmarking, there is no guarantee of purity.

BIS Hallmark India – Why It Matters Today

Earlier, hallmarking was optional in many places. But now, the government has made BIS hallmark India rules stricter to protect buyers from fraud and under-purity jewellery.

Today, most jewellers must sell only hallmarked gold items. This ensures:

• Fair pricing
• Consumer protection
• Standard purity across the country
• Better resale value

If a jeweller sells non-hallmarked gold in mandatory areas, penalties may apply.

What Does a BIS Hallmark Include?

When you look closely at gold jewellery, you will see small symbols stamped on it. These markings confirm authenticity.

A proper hallmark on gold includes:

➜ BIS hallmark logo – shows certification by BIS

➜ Purity mark (carat or fineness) – like 22K916 or 18K750

➜ Assay centre mark – where purity was tested

➜ Jeweller’s identification mark

➜ HUID number (Hallmark Unique Identification)

The HUID is very important. It allows you to verify jewellery online.

Benefits of Buying BIS Hallmarked Jewellery

Buying hallmarked jewellery is always safer.

Key advantages:

● Guaranteed purity

Always check that:

➤ The logo is clearly stamped
➤ The mark is readable

If any of these are missing, ask the jeweller for clarification.
