This hallmarking of gold jewelery was established in April 2000. It consists of a BIS logo, a 3 digit number that indicates the gold purity, the logo of the assaying center along with the logo or the code of the jeweler and the code that indicates the hallmarking date. This hallmarking has a high reputation among the jewelery industry in India.
