India, the world’s second-largest gold consumer, uses approximately 849 metric tons of gold annually, primarily for jewellery and ornamental purposes. Beyond its beauty, gold is valued as a secure store of wealth. But how can consumers ensure its authenticity?
To combat fraud in gold sales, the Government of India made hallmarking mandatory. Jewellers must now obtain a certificate of registration to sell hallmarked jewellery, ensuring compliance with quality standards.
Enter the Hallmark Unique Identification (HUID) number—a game-changing system designed to boost consumer confidence. This six-digit alphanumeric code guarantees traceability and authenticity, enabling buyers to verify the purity of their gold easily. A significant step towards safeguarding investments and promoting transparency in the gold market!
Understanding Hallmark Unique Identification (HUID Number)
The Hallmark Unique Identification (HUID) Number is a six-digit alphanumeric code assigned to each piece of jewellery during the hallmarking process. This unique number is laser-inscribed onto the jewellery, ensuring its authenticity. Additionally, the HUID details are securely stored in the BIS database, providing reliable traceability and enhancing consumer confidence.
In 2021, the Government of India introduced the HUID (Hallmark Unique Identification) number to benefit gold jewellery customers. Since then, all hallmarked gold items must carry this unique HUID. The BIS hallmark comprises three symbols: the BIS logo, an indication of purity and fineness, and the HUID number. Buyers are encouraged to verify the HUID number when purchasing gold jewellery to ensure its authenticity and compliance.
What is Hallmarking?
Hallmarking is the process of accurately determining and certifying the purity of precious metals in articles like jewellery. It serves as an official guarantee of quality and fineness, recognized in many countries. In India, the Hallmarking Scheme aims to protect consumers from adulteration while ensuring that manufacturers meet legal standards of purity. Currently, gold and silver are the two precious metals under mandatory hallmarking, promoting transparency and safeguarding consumer trust.
