The guide will explain gold hallmarks and BIS certificates and what they mean to people who buy gold in India, especially for people who buy gold jewelry.
What Is a BIS Certificate for Gold Hallmark?
BIS is a certification program that is administered through the Bureau of Indian Standards that assures the purity of jewelry. A BIS stamp on a gold product proves that it was tested by a recognized BIS assaying and hallmarking center and is in compliance with established purity standards.
Why Was It Made Mandatory?
There was a lot of gold purity fraud in India before the mandatory hallmarking. Jewelry sold as 22-karat can be less pure than stated. BIS’s mandatory marking will end this practice by requiring independent third-party testing of all gold jewelry sold within India.
Gold Hallmark Symbols: What Do They Mean?
Every BIS hallmarked gold item carries specific marks. Here is what each symbol means:
| Symbol | Meaning |
| BIS Logo | Triangle-shaped mark—confirms BIS certification |
| Purity / Fineness | 999, 995, 916, 875, 750, 585—indicates gold purity in parts per thousand |
| HUID Number | 6-character alphanumeric code—unique to each piece of jewellery |
Common Gold Purity Standards
| Hallmark Number | Karat | Purity |
| 999 | 24 Karat | 99.9% pure |
| 995 | 24 Karat | 99.5% pure |
| 916 | 22 Karat | 91.6% pure |
| 750 | 18 Karat | 75% pure |
| 585 | 14 Karat | 58.5% pure |
| 375 | 9 Karat | 37.5% pure |
Most gold jewelry sold in India is 22 karat (916). If your jewelry shows 916 with a BIS logo and HUID, it is genuine 22-karat gold.
What Is an HUID Number?
HUID stands for Hallmark Unique Identification Number. It’s a 6-character alphanumeric code that is stamped on each piece of BIS jewelry that is hallmarked with gold. The number is recorded on BIS’s central database. BIS central database, and it links each piece of jewelry:
