What to look for on hallmarked gold jewellery in India

A jeweller lifts a bangle under the lamp, and the real test is only a glance away

The fastest way to protect yourself at the counter is to check three marks, not one. On hallmarked gold jewellery in India, the Bureau of Indian Standards says the hallmark now consists of the BIS logo, the purity of the article in caratage and fineness, and a six-digit alphanumeric HUID. Those tiny stamps are doing heavy lifting: they tell you the piece has a documented identity, a declared purity and a traceable record that can be checked before money changes hands.

The three marks that matter

The BIS logo is the first thing to look for. It signals that the piece is part of the formal hallmarking system, rather than a seller’s own promise written on a bill or tag. That matters because gold buyers are often paying based on trust alone, and trust is exactly where purity disputes begin.

The purity mark comes next. This is the caratage and fineness declaration, the part that tells you whether the piece is 22K, 18K or another specified purity. Without that mark, the number on the receipt is just marketing. With it, the metal itself is stating what it is supposed to be.

The third mark is the one many buyers now need to learn by eye: the 6-digit alphanumeric HUID. Since 1 July 2021, BIS has said hallmarking on gold jewellery carries this unique code, and that every hallmarked item has its own HUID. That turns a generic ornament into an individually traceable object, which is the difference between a vague promise and a piece that can be checked.

Why HUID changed the counter conversation

Before HUID, buyers could be left with a hallmark that was harder to tie back to a specific item. The new system makes each piece identifiable, and that is where consumer protection becomes practical. BIS says the HUID can be verified in the BIS Care App through the “Verify HUID” feature, which gives buyers a direct way to test whether the number on the jewellery matches the record behind it.

That matters in daily life more than most shoppers realize. A misread purity mark can mean overpaying for under-purity gold. A missing or weak hallmark can make resale more difficult. And a non-compliant piece, especially one sold as hallmarked without the proper HUID, can leave you with less protection if purity is ever disputed.

BIS frames hallmarking as protection against purity-related malpractices, and also as part of a wider ambition to build India into a leading gold market centre and improve export competitiveness. In other words, the mark is not just about consumer confidence at the shop floor. It is also about creating a cleaner market that buyers at home and abroad can trust.

How to verify the 6-digit HUID before paying

This is the part to do while the jewellery is still on the tray, before the bill is printed and before the packet is sealed.

3. Match the code to the item in front of you. The code should correspond to the specific hallmarked article you are buying, not just any piece of similar design.

This takes less than a minute and can save far more than a minute’s embarrassment later. If a seller hesitates to show the HUID or discourages app verification, that is itself useful information.

What the rule change means for buyers

On 4 March 2023, the government said sale of hallmarked gold jewellery or gold artefacts without the 6-digit alphanumeric HUID would be prohibited after 31 March 2023. The same announcement made clear that older hallmarked jewellery with four marks could still be sold during the transition period. That detail matters because it explains why buyers may still encounter older stock, but it does not weaken the current standard for new purchases.

The message for shoppers is simple: if you are buying now, expect the three-mark system. A piece that still relies on the old four-mark format may be legitimate stock from the transition period, but it should not be used to blur the standard a modern buyer should insist on. The absence of HUID is not a small clerical issue. It is the difference between a piece that fits today’s compliance system and one that does not.

The scale of the rollout shows how normal this system has become

By 14 November 2024, the Centre said more than 40 crore gold jewellery items had been hallmarked with a unique HUID. The fourth phase of mandatory hallmarking began on 5 November 2024, adding 18 districts and taking the total covered under mandatory hallmarking to 361 districts. That scale tells you two things at once: this is no longer a niche compliance feature, and it is becoming the baseline expectation across much of the market.

BIS identifies the relevant gold hallmarking standard as IS 1417:2016. For the buyer, that standard matters less as a number to memorize than as proof that the system is formal, structured and nationally recognized. The practical takeaway is unchanged: if a seller says a piece is hallmarked, the marks should be visible, readable and verifiable.

What to inspect in under a minute

When you are standing at the counter, keep your eye on the simplest checklist:

• BIS logo
• Purity mark in caratage and fineness
• 6-digit alphanumeric HUID
• Verification of that HUID in the BIS Care App
• Clear readability on the exact piece you are buying

If the seller offers only a verbal assurance of purity, treat that as incomplete. If the hallmark is present but blurred, ask for a clearer view. If the HUID cannot be checked, do not let the conversation move on as if nothing happened.

Gold is supposed to be the safest purchase in the room. Hallmarking is what keeps it that way. In a market where a bracelet can look beautiful and still be under-pure, the three marks and the HUID check are the fastest way to make sure the metal lives up to the price.
