The Hallmarking
of Gold Jewellery in India
BIS hallmark for gold jewellery consists of five components:
- (1) The BIS logo
- (2) A three digit number (out of a set of six
pre-defined values) indicating the purity of the gold in
part-per-thousand-format viz; 958, 916, 875, 750, 585, 375. Thus
a BIS 916 hallmark would certify to a purity of 916 per 1000,
that is 91.6%, translating to a 22 carat purity of gold.
