3 Signs of Authentic BIS Hallmarking
Always look for these three mandatory marks on your gold jewellery to ensure 100% purity and government compliance.
1. BIS Standard Mark
The triangular BIS logo guarantees that the gold piece complies with Bureau of Indian Standards specifications.
2. Purity & Fineness
Indicates gold purity: 916 (22K), 750 (18K), or 585 (14K), stating exact gold percentage.
3. 6-Digit HUID
A unique alphanumeric code laser-etched onto every piece for traceability and authenticity verification via the BIS Care App.
