The Bureau of Indian Standards is India’s national standards body. It acts as the hallmarking agency for gold and silver, certifying the purity and fineness of jewellry. BIS-certified jewellry assures consumers of its quality and adherence to Indian standards.
BIS Hallmarking Components
BIS hallmarking consists of five components:
- BIS Standard mark
- Purity grade (e.g., 916 for 22 karat gold)
- Mark of the hallmarking centre
- Year of hallmarking
- Jewellers identification mark
