How to Check Gold Hallmark: Step-by-Step Buyer Guide

How to check gold hallmark in under five minutes

To check a gold hallmark, find the tiny laser mark on the piece, confirm it shows the BIS logo, a purity grade such as 22K916 and a six-digit HUID, then enter that HUID in the official BIS Care app to confirm the details. If anything does not match, ask the jeweller before you pay.

Knowing how to check gold hallmark details puts you in control at the counter or when an online order arrives. You do not need special training, only a magnifier or a phone camera with zoom, the app on your phone and a few minutes of patience.

Many people feel awkward asking to inspect the hallmark, worrying that it seems distrustful. In reality, jewellers deal with this every day, and a genuine seller expects informed customers. Checking the hallmark is as normal as checking the expiry date on medicine. Doing it calmly and confidently also signals that you know what you are buying, which often leads to clearer conversations about price and making charges too.

Step 1: Locate the hallmark on the piece

Hallmarks are deliberately small so they do not spoil the design. On rings, look inside the band. On chains, check the clasp, the hook or a small tag plate near the end. On bangles and kadas, look along the inner surface. Earrings usually carry the mark near the post, on the back plate or on the hook. Pendants carry it on the reverse or on the bail.

Use good light and your phone's zoom or a jeweller's loupe. In a store, ask the salesperson to point to the mark; good jewellers are used to this request. When buying online, check product photos for a hallmark close-up and inspect the piece on delivery.

For heavier sets such as necklaces with multiple sections, the hallmark may appear on the main body, on a hook, or on a tag attached near the clasp. Bangles sold in pairs are usually marked individually. If you are buying a set with many components, take a moment to locate each mark and match it to the invoice before the items are packed, because finding them later at home can be harder.

Step 2: Read the three components

A current hallmark has the BIS triangular logo, the purity grade and the HUID. Purity grades combine karat and fineness: 22K916 means 22 karat at 91.6 percent gold, 18K750 means 75 percent, and 14K585 means 58.5 percent. Make sure the grade matches what is written on the price tag and the bill.

The HUID is a six-character mix of letters and numbers. Write it down or photograph it clearly. Some pieces such as earrings may carry the mark on one part only, so check both earrings and ask how they are marked if you cannot find it.

Pay attention to the format of the purity grade. It should show both the karat and the fineness together. A piece marked only with 916 in an older style may be from before the HUID system. A piece marked with an unusual combination, or with a karat that does not correspond to the fineness, deserves a question. Correct pairs are 22K with 916, 18K with 750 and 14K with 585, among the standard grades.

Step 3: Verify in the BIS Care app

Download the official BIS Care app from your phone's app store, checking that the publisher is the Bureau of Indian Standards. Open the section for verifying HUID, enter the six-digit code, and submit. The app typically shows information such as the purity, the type of article and the registered jeweller and hallmarking centre.

Compare these details with the piece in your hand. A ring should not show up as a pendant, and an 18K item should not show up as 22K or vice versa. If the details match, you have strong confirmation that the hallmark is genuine.

If you are in a store with poor mobile network, ask the jeweller to let you use their Wi-Fi or step outside briefly. Do not skip verification just because it is inconvenient in the moment. For high-value purchases, some buyers verify the HUID while the item is being packed, then confirm the bill before paying. This sequence ensures you never pay for a piece you have not checked.

Step 4: Check the bill matches the hallmark

Your invoice should list the item description, the purity, gross weight, net weight, any stone weight, the gold rate applied, the making charges, stone charges and GST. Many jewellers also print the HUID on the bill. Make sure every detail aligns with the hallmark and the app result.

This document is what you will rely on for exchange, buyback or an insurance claim. If the bill says only a total amount with no breakup, ask for a detailed version. A reputable seller will provide it without fuss.

When buying a set, such as a necklace with matching earrings, each component may carry its own HUID or the set may be documented in a particular way. Ask the jeweller how the set is marked and ensure the invoice reflects every item and its weight. Sets are often exchanged or redesigned piece by piece later, so individual documentation is valuable.

Warning signs to watch for

Be cautious if the mark is missing or smudged, if it lacks the BIS logo, if the code is not six characters, or if the purity grade looks unusual. Be equally careful when the app shows details that do not match the piece. Another warning sign is a seller who discourages you from checking or offers a discount for skipping the bill.

Hand-stamped or punched-looking marks rather than clean laser marks may also deserve a closer look. None of these automatically proves fraud, but they are reasons to ask questions, request an independent test or simply walk away.

Remember that very light articles may fall under exemptions from mandatory hallmarking, depending on current rules. If you are buying a tiny nose pin or a very light pendant and it is not hallmarked, ask why, and decide whether you are comfortable with the jeweller's explanation. For anything of meaningful value, a HUID hallmark is the standard you should expect.

Also note that hallmarking applies to the precious metal. If your piece contains diamonds, request the grading report or at least a written declaration of diamond weight and quality on the invoice.

Checking old family jewellery

Pieces bought years ago may carry the older hallmark format or none at all. You cannot verify these through HUID, but you can have them tested. Many jewellers use non-destructive XRF machines to estimate purity in minutes, and some hallmarking centres also offer testing services to the public for a fee.

If you are planning to exchange or redesign old pieces, testing first tells you what you really own. It also helps you compare offers from different jewellers fairly, since you will know the purity before anyone quotes a price.

Some customers also take old jewellery to two different jewellers for testing when the amount involved is large. If both results are close, you can be confident about purity. If they differ, a hallmarking centre test can settle the question. Small differences in tested purity can mean noticeable differences in exchange value on heavy pieces, so a second opinion is often worth the effort.

Make checking a habit

Whether you are buying a small pair of studs or a wedding set, the routine is the same: locate, read, verify, match with the bill. It takes a few minutes and protects a purchase that may be worth lakhs. Keep photos of each hallmark and HUID with your digital records.

Once you are comfortable with the process, you will find that buying gold becomes calmer and more enjoyable, because you are choosing on design and price with confidence that the purity is real.

Teach these steps to family members too. Parents and grandparents who bought jewellery before HUID existed may find the app unfamiliar, while younger buyers may not know which marks to look for. A short demonstration at home, using a piece you already own, makes everyone more confident when they next visit a jeweller or receive jewellery as a gift.
