Hallmark Jewellery Guide: What Every Gold Buyer Should Know
When you buy gold jewellery, you’re not just purchasing an ornament—you’re investing in purity, trust, and value. That’s why checking for a BIS Hallmark is one of the most important steps before making your purchase.
What is a Hallmark?
A BIS Hallmark is the official certification of gold purity issued by the Bureau of Indian Standards (BIS). It assures that the jewellery has been tested and meets the declared purity standards.
How to Identify Hallmarked Jewellery?
Every hallmarked gold jewellery piece should have:
- BIS Logo
- Purity Mark (916 for 22K, 750 for 18K, 585 for 14K)
- 6-Digit HUID (Hallmark Unique Identification) Number
The HUID is unique to each jewellery piece and can be verified through the BIS Care App.
Understanding Gold Purity Marks
| Purity Mark | Carat | Gold Purity |
|---|---|---|
| 999 | 24K | 99.9% |
| 916 | 22K | 91.6% |
| 750 | 18K | 75.0% |
| 585 | 14K | 58.5% |
22K (916) is the most preferred choice for traditional jewellery, while 18K (750) is commonly used for diamond jewellery.
Why Should You Buy Hallmarked Jewellery?

You get exactly the purity you are paying for.
Better Resale & Exchange Value
Hallmarked jewellery is easier to exchange and receives greater trust during resale.
