# The Bourn Ring

The BIS hallmark is a system that provides certification of gold that indicates the purity of the metal. It authenticates that a piece of gold jewelery purchased, conforms to the standards as laid by the Bureau of Indian Standards which is the national standards organization in India.

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.
