ToggleWhat Is Hallmark Gold?
What is Hallmark gold ? It refers to gold jewelry or articles that have been officially tested and certified for purity by an authorized hallmarking center. Once tested, the gold is stamped with a special mark called a hallmark, which indicates the metal’s purity and authenticity.
In India, hallmarking is regulated by the Bureau of Indian Standards (BIS). BIS hallmark ensures that the gold content in the jewelry matches the karat or fineness claimed by the jeweler. In simple words, hallmark gold means certified gold that meets national quality standards.
For example, if a necklace is sold as 22K gold, hallmarking confirms that it actually contains 91.6% pure gold and not less.
💎 Why Is Hallmark Gold Important?
Hallmark Gold is expensive and even a small difference in purity can result in a significant loss of money. Without hallmarking, buyers must blindly trust the jeweler’s claim. Hallmarking provides transparency and confidence.

🏷 What Do the Numbers on Hallmark Gold Mean?
You may have noticed numbers like 916, 750, or 585 engraved on Hallmark gold jewelry. These numbers represent the purity of gold in parts per thousand.
| Karat | Mark | Gold Purity |
|---|---|---|
| 24K | 999 | 99.9% pure |
| 22K | 916 | 91.6% pure |
| 18K | 750 | 75.0% pure |
| 14K | 585 | 58.5% pure |
- 24K gold is almost pure but too soft for making jewelry.
