Hallmarking Center License Setup

An A&H centre will certify the purity of gold jewellery of 14, 18 and 22 carat, six grades for silver jewellery, gold coins and medallions of 24 carat. Only when an A&H centre assays the article and assigns a hallmark, can it be taken to be of certified purity.The laboratory where your gold jewellery is assessed to check its purity is also required to put their logo on the jewellery. Only licensed laboratories of BIS can check the purity of gold. One can check if the hallmarking centre is licensed by BIS or not on their website.
