How to Read a Gold Hallmark Before You Buy
Buying gold jewellery is more than choosing a beautiful design. Whether you're purchasing a delicate bracelet for your child, a personalized name chain, or a timeless piece for yourself, understanding the gold hallmark can help you make a more informed purchase.
A hallmark is an official indication of the purity or fineness of precious metal. In India, gold jewellery is hallmarked under the Bureau of Indian Standards (BIS) system, giving buyers an additional layer of assurance about the purity of the gold they are purchasing.
So, what exactly should you look for when buying gold jewellery?
What Is a Gold Hallmark?
A hallmark is a set of official marks applied to gold jewellery after it has been tested for purity.
For hallmarked gold jewellery under the current system, there are three key marks:
- BIS Standard Mark
- Purity mark showing caratage and fineness
- Six-digit alphanumeric HUID (Hallmark Unique Identification) number
Knowing what each mark means makes it much easier to understand what you're buying.
1. Look for the BIS Logo
The first thing to identify is the BIS Standard Mark.
BIS, or the Bureau of Indian Standards, operates India's hallmarking system and uses hallmarking as a way to provide consumers with assurance regarding the purity of precious-metal jewellery.
When buying hallmarked jewellery, look for the BIS mark along with the other required hallmark details.
2. Understand the Purity Mark
The purity mark tells you the gold content of the jewellery.
You may commonly see markings such as:
- 14K 585 – 14-carat gold with fineness of 585 parts per thousand
- 18K 750 – 18-carat gold with fineness of 750 parts per thousand
- 22K 916 – 22-carat gold with fineness of 916 parts per thousand
BIS currently permits hallmarking for several gold fineness grades, including 14K (585), 18K (750), 20K (833), 22K (916), 23K (958), and 24KS (995).
Understanding these numbers makes it easier to compare different gold jewellery pieces.
3. Check the HUID Number
One of the most important additions to India's current hallmarking system is the HUID.
HUID stands for Hallmark Unique Identification. It is a unique six-digit alphanumeric number assigned to each hallmarked jewellery article.
You can use the BIS Care App's "Verify HUID" feature to check the details associated with a hallmarked jewellery item.
This is particularly useful when you want to verify the jewellery you're purchasing rather than relying only on a visual inspection of the hallmark.
4. Don't Judge Gold by Appearance Alone
Two pieces of jewellery can look almost identical while having different gold purities.
The colour, finish, design, and craftsmanship tell you about the appearance of a piece—but the hallmark provides important information about its declared purity.
This is why checking the hallmark should become part of your buying process, especially when purchasing valuable gold jewellery.
5. Check the Jewellery Bill
Your purchase invoice is another important part of buying gold jewellery.
BIS states that the bill or invoice for hallmarked precious-metal jewellery should include details such as the description of each article, net precious-metal weight, purity in carat and fineness, and hallmarking charges.
Always keep your invoice safely. It provides useful documentation for the jewellery you've purchased and can be important if you ever need to raise a concern or verify purchase details.
6. Look at Each Piece Individually
If you're purchasing jewellery in pairs or jewellery with detachable parts, don't assume that one hallmark covers everything.
BIS advises consumers to look for hallmarking and fineness details on each article in a pair and on detachable parts where applicable.
This is especially useful when buying earrings or jewellery made up of multiple detachable components.
Why Hallmarking Matters for Children's Jewellery
When buying gold jewellery for children, parents often look for pieces that are meaningful, beautiful, and made to last.
A tiny personalized bracelet or name pendant may eventually become a treasured childhood keepsake. Understanding its gold purity and checking its hallmark gives parents greater confidence in the purchase.
For jewellery that may be kept for years—or even passed down to another generation—knowing exactly what you're buying matters.
A Simple Checklist Before Buying Gold Jewellery
Before you make your purchase, take a moment to check:
✓ BIS Standard Mark

The Beauty of Knowing What You're Buying
Gold jewellery carries emotional value, especially when it is connected to a milestone, a celebration, or someone you love.
Whether it's your child's first bracelet, a personalized name chain, or a piece chosen to become a family heirloom, understanding the hallmark adds another level of confidence to the purchase.
At Doodles by Purvi, we believe that choosing jewellery should feel as special as the occasion it celebrates. Beautiful design matters, but so do craftsmanship, quality, and transparency.
Conclusion
Understanding a gold hallmark doesn't have to be complicated. Once you know what the BIS mark, purity number, and HUID represent, you can approach your gold jewellery purchase with greater confidence.
The next time you're choosing a gold bracelet, necklace, pendant, or personalized piece, take a moment to look beyond the design. Know your gold, check your hallmark, and choose a piece that you can treasure with confidence.
