About Hallmarking
 

In India, Hallmarking Scheme was launched by Bureau of Indian Standards at behest of Government of India in the Year 2000 to protect the consumer interest. The Scheme is voluntary in nature in nature till now and those jewellers wishing to get their jewellery hallmarked are provided a fee based license by BIS before tendering the jewellery to a BIS recognized A&HMC.

As per Bureau of Indian Standards' Hallmarking Scheme, a license is given to jewellers / Jewellery manufacturers, after ensuring that it meets all the requirements of IS 1417:1999 for its manufacturing practice and purity. 

 A Hallmark, which must consist of Bureau of Indian Standards Logo, the fineness number, mark of Assaying and Hallmarking Centre where jewellery has been assayed and marked, year of Mark and Jeweler's / Jewellery manufacturer's Mark, means that the article has been independently tested by a Hallmarking Centre and assures that it conforms to the marked purity. 

The centers for Assaying and Hallmarking are recognized by Bureau of Indian Standards after assessing that all the operations carried out in the centre are as per the Bureau of Indian Standards norms i.e. receipt, sampling, assaying and hallmarking. The assaying laboratory is also assessed as per the ISO/IEC 17025 - 1999. (General requirements for the technical competence of testing laboratory) 

The general as well as the technical criteria for the recognition of a Hallmarking and Assaying Centre operating under Bureau of Indian Standards criteria for hallmarking of gold jewellery are documented based on IS/ISO 9001 - 2000 in tandem with ISO/IEC – 17025.

Specific Instructions for Submission of Jewellery for Hallmarking:
 
1. Before tendering jewellery for hallmarking, from each lot (either manufactured by same Gold smith or of similar design/Technology) a representative sample must be fire assayed (destructive sampling) to confirm the fineness for which is to be hallmarked. A record for the same is essential to ensure that the jewellery being sent for hallmarking meets declared purity.
2. Hollow and studded Jewellery is not normally accepted for hallmarking. Hence it is advised to send jewellery in semi finished condition (before studding) to avoid any damage.

3.

Each piece of jewellery must have an identification logo (jeweler's logo) and the year of manufacture (Code Letter as decided by Bureau of Indian Standards e.g. letter 'A' denotes Year 2000 which represents the year of hallmarking, the current code letter 'E' denoting year 2004).
4. Ensure that there is a suitable provision on the piece of jewellery where hallmarks can be put. If this is not the case, provide with soldered strip at suitable place on the jewellery on which hallmarking can be done.
5. When jewellery being sent for hallmarking is manufactured by different artisans, segregation of the articles is to be done in different lots for each artisan. This is to be specified in the Issue Voucher so as to make sampling easier.
6. The jewellery being sent must be properly packed and sealed. It must also accompany with it a detailed list of items, quantity and weight.
