Hallmarking is the accurate determination and official recording of the proportionate content of precious metal in precious metal articles. 

• It certifies that the piece of jewellery conforms to a set of standards laid by the Bureau of Indian Standards, the national standards organization of India.
• As per this scheme, Registration is granted to the jewellers by BIS under Hallmarking Scheme. 

The BIS certified jewellers can get their jewellery hallmarked from any of the BIS recognized Assaying and Hallmarking Centres.
