Hallmarking is used to certify the purity or fineness of jewellery and other articles made of precious metals. According to the Bureau of Indian Standards (BIS), hallmarking means the accurate determination and official recording of the proportionate content of precious metal in a precious-metal article. In India, a hallmark serves as an official guarantee of the purity or fineness of precious-metal articles.

Under the present BIS Hallmarking system in India, gold and silver are the two precious metals covered by hallmarking. Gold and silver jewellery/artefacts can therefore be hallmarked. One of the principal objectives of the scheme is to protect consumers from malpractices relating to the purity of jewellery and provide assurance regarding the declared fineness of the metal purchased.

An important fact is that after the introduction of HUID, hallmarked gold jewellery carries the BIS logo, purity in carat/fineness and a six-digit alphanumeric HUID. Each HUID is unique and traceable, and consumers can verify it through the BIS Care App.
