It is important to check the purity of gold, because there is a danger of fake gold in the market. 24K is the purest, but jewelry typically ranges from 14K to 22K. It is mandatory to have BIS hallmark on every jewellery. For example, 22K is the number ‘916’. Jeweller, Hallmark Centre, article type and purity can be instantly verified by entering the 6-digit alphanumeric code of the hallmark in the BIS Care mobile app.
