How to Identify a Genuine Hallmark on a Gold Chain
A genuine hallmark on a gold chain is an official mark that verifies the purity and authenticity of the gold. To identify it, look for the BIS logo, the purity mark (such as 22K916 or 18K750), the jeweller’s identification mark, and the hallmarking centre’s symbol. These markings are usually engraved on the clasp or a small link of the chain. You can also verify the hallmark using the BIS Care mobile app or the BIS website. Checking these details helps ensure you are purchasing certified gold and protects you from counterfeit or low-purity jewellery.
