BIS Hallmarking for 18k gold is a certification issued by the Bureau of Indian Standards (BIS). It verifies that the jewelry contains 75% pure gold. The hallmark includes the “750” mark, the BIS logo, and a unique tracking number.
18k gold contains 75% pure gold and 25% alloy metals. It is known for its strength and durability. This makes it a popular choice for everyday jewelry that needs to withstand regular wear. Hallmarking has been mandatory for gold jewelry and artefacts in India since 23 June 2021. This requirement comes under the Bureau of Indian Standards (Hallmarking of Gold Jewellery and Gold Artefacts) Order, 2020.
18k gold is especially common in diamond-studded and Western-style jewelry. Its higher alloy content makes it stronger and better suited for securing stone settings. In comparison, purer 22k and 24k gold are softer and more prone to bending.
Key Takeaways
- BIS hallmarking confirms that 18k gold contains 75% pure gold. It carries the “750” purity mark and BIS logo.

- Old-format hallmarks without a HUID number have been unsellable since 1 April 2023.
- Mandatory hallmarking covers six purity grades: 14K, 18K, 20K, 22K, 23K, and 24K. A 9K option is also available voluntarily.
- Hallmarking coverage has expanded to 380 districts. This expansion took effect in March 2026.
- As of 13 August 2026, 18K gold costs around ₹11,500–₹11,650 per gram nationally. Rates change daily and may vary by city.
Why Do You Need BIS Hallmarking for 18k Gold?
Hallmarking changes how you verify gold when you buy it. You no longer have to rely only on a jeweler’s claim. You can check the purity through an independent certification.
Here are the key benefits:
- Assurance of Purity: A BIS hallmark confirms that your 18k gold meets the 75% purity standard. This gives you more confidence in your purchase.
- Prevention of Fraud: Uncertified gold may carry a higher risk of being substandard or counterfeit. Hallmarking helps protect you from such risks.
- Increased Trust and Transparency: Hallmarking lets you verify the gold’s authenticity independently. You do not have to rely only on the seller’s word.
- Government-Mandated: Hallmarking is mandatory for six purity grades: 14K, 18K, 20K, 22K, 23K, and 24K. It now covers 380 districts as part of the sixth rollout phase introduced in March 2026. A 9K grade is also available voluntarily.
- Higher Resale Value: Hallmarked 18k gold can offer better resale confidence. Buyers and jewelers can verify its purity instead of relying only on the seller’s claim.
Choosing gold without a genuine hallmark can increase your risk. Properly hallmarked 18k gold gives you greater confidence in its purity and authenticity.
How to Verify a HUID Number?
Before buying gold jewelry, buyers can verify whether the hallmark is genuine. Follow these steps:
- Download the BIS CARE app. It is available on both Android and iOS.
- Select the “Verify HUID” option.
- Enter the six-digit alphanumeric HUID number stamped on the jewelry.
- Check the registered details. These may include the supplier’s or manufacturer’s registration information.
The process takes less than a minute. It helps confirm whether the jewelry is registered in the BIS database. It can also help identify counterfeit or fake hallmark marks.
