The BIS hallmarking scheme has been aligned with international criteria on hallmarking (Vienna [ Images ] Convention 1972). As per this scheme, licence is granted to the jewellers by BIS under Product Certification Scheme. The BIS certified jewellers can get their jewellery hallmarked from any of the BIS recognised Assaying and Hallmarking Centre.
In this process the samples are melted and refined at the hallmark centre to get the purity of 22 carat Gold at *916 marks provided for purity by the hallmark authorities.
