Kolkata: Major jewellers in the country have appealed to the government for standardisation in hallmarking of gold, contending that multiple measures of purity involved in the process was creating confusion in the industry. The All India Gem and Jewellery Domestic Council (GJC) has urged the consumer affairs ministry for standardisation in hallmarking purity across the country. Vice-chairman of GJC, Shaankar Sen, said that various forms of purity like 14, 18 and 22 carats are being used for the hallmarking process. Citing an example, Sen said that for gold bars and coins, the purity required for hallmarking is 20 and 24 carats, respectively. This, he said, was creating confusion in the jewellery industry, necessitating standardisation.
