Some leading jewelers across the country staged a token strike against the central government’s move making hallmarking of gold jewelry with unique identification number (HUID) mandatory from June 16. Most of the small and medium size jewelers however did not support the strike as they welcomed the government move making HUID of gold jewelry mandatory across the country, claimed Pankaj Arora, National President of All India Jewelers and Goldsmiths Federation (AIJGF).
