Why in news? Union Ministry of Consumer Affairs, Food and Public Distribution reported that, the sale of gold jewellery will not be allowed without a Hallmark Unique Identification (HUID) number.


What is HUID number on gold jewellery?

  • HUID number is a six-digit alphanumeric code.
  • It is given to every piece of jewellery at the time of hallmarking, and is a unique identifier for each gold item.
  • The jewellery is stamped with the unique number manually at the Assaying & Hallmarking centre.
  • It will be easy to trace the individual piece of jewellery, and is a guarantee of quality.
  • In HUID-based Hallmarking, registration of jewellers is automatic with no human interference.
  • It is a secure system and poses no risk to data privacy or security

Why is hallmarking of gold jewellery important?

  • Hallmark is a mark on gold jewellery which is affixed by an entity recognised by Bureau of Indian Standards (BIS) to assure its fineness and purity

How to check for this hallmark?

  • A BIS Hallmark consists of three symbols — the BIS logo, a symbol to indicate the purity and fineness of the jewellery, and then the HUID.
  • 22K916 is a 22 carat gold piece of jewellery that has 91.6 percent gold.
  • 18K750 is an 18 carat gold piece of jewellery has 75 percent gold.
  • 14K585 is a 14 carat gold piece of jewellery has 5 percent gold.

How can you check the purity of old jewellery?

  • Purity of gold jewellery can be checked at any BIS-recognized Assaying and Hallmarking Centre with minimal fee of Rs 200.
  • Consumer cannot apply to the Assaying and Hallmarking Centre for getting a hallmark on her gold jewellery. This has to be done through a BIS-registered jeweller.

What are the benefits of hallmarking?

  • The most important benefit is that the consumer is aware of the quality of the product she is buying and will not be cheated.
  • Since the quality of the jewellery is guaranteed, that piece will fetch a higher price when re-sold.
  • Banks are likely to give loans on better terms if the mortgaged jewellery is hallmarked.
