“Hallmark Unique Identification” (HUID) is a system developed by the Bureau of Indian Standards (BIS) to authenticate and identify the purity of gold and other precious metals used in jewelry. It is a unique identification number that is assigned to each piece of jewelry that meets the prescribed standards.

The HUID system was introduced in India in 2019, and it aims to protect consumers from fraudulent practices in the jewelry industry. To get a HUID, jewelers must register with BIS and submit their jewelry for testing to ensure that it meets the required standards for purity. Once the jewelry is certified, a unique HUID number is assigned and engraved on the jewelry itself.

Consumers can use the HUID number to verify the authenticity of their jewelry by checking it against the BIS database, which contains information on all certified jewelry. This provides consumers with an added level of confidence when purchasing jewelry, as they can be sure that they are getting what they pay for.
