The BIS Hallmark certification standards are laid out by the Bureau of Indian Standards, the National Standards Organization in India. The BIS Hallmark certification helps accurately determine, authenticate, and officially record the proportionate content of precious metal in precious metal jewellery. The BIS Hallmark system certifies both gold and silver jewellery in terms of the purity of the metal. The stamp of the BIS hallmark on the gold and silver jewellery depicts the purity of the jewellery, which is later checked at a BIS-certified center.
The hallmark majorly constitutes a BIS (Bureau of Indian Standards) mark denoted using a triangle, the caratage number indicating the purity of the jewellery, along with the logo of the assaying center including the code of the jeweller and the code that indicates the hallmarking date.
The principal objective of the BIS Hallmark certificate is to safeguard the public against adulteration and to obligate jewellery manufacturers to maintain legal standards of fineness. The long-standing reputation and trustworthiness of the BIS Hallmark certificates have made them the most widely accepted standards among precious metal jewellery traders, manufacturers, and consumers.
