Before purchasing gold jewellery in India, it is essential to understand the gold hallmarking process. Knowledge of HUID (Hallmark Unique Identification) Registration helps consumers verify purity and protects them from adulteration or misrepresentation.
In India, the sale of hallmarked gold jewellery is mandatory in notified districts having BIS-recognized Assaying & Hallmarking Centres (AHCs). With this awareness, buyers can confidently identify genuine gold jewellery and make informed purchasing decisions.
What is Hallmarking?
Hallmarking is the precise evaluation and official recording of the purity and fineness of precious metals used in jewellery or artifacts. A hallmark is an official stamp that certifies the metal content as per prescribed standards.
The key objectives of hallmarking are:
Protect consumers from adulteration
Ensure compliance with purity standards
Enforce transparency in the jewellery trade
In India, hallmarking is currently applicable to gold and silver and is governed by the Bureau of Indian Standards (BIS).
BIS Hallmarking in India
BIS Hallmarking is a certification system that verifies the purity of gold and silver jewellery sold across India. BIS, India’s national standards body, authorizes Assaying & Hallmarking Centres (AHCs) to test and stamp jewellery as per notified Indian Standards.
Gold hallmarking in India began in April 2000 and has since become the most reliable method for verifying gold purity.
Hallmarked jewellery assures that:
The purity has been tested
The jewellery complies with BIS standards
The product meets national and international fineness norms
What is HUID Hallmarking?
HUID (Hallmark Unique Identification) is a six-digit alphanumeric code introduced by BIS to uniquely identify each piece of hallmarked gold jewellery.
HUID enables:
Traceability of jewellery
Prevention of duplicate or fake hallmarking
Easy verification by consumers through the BIS Care app
BIS Hallmark Components (Current System)
Under the BIS hallmarking system, gold jewellery carries the following key markings:
