The BIS Hallmark is a hallmarking system for gold as well as silver jewellery sold in India, certifying the purity of the metal.[1][2] It certifies that the piece of jewellery conforms to a set of standards laid by the Bureau of Indian Standards, the national standards organization of India . India is the second biggest market for gold and its jewellery.
India imports in excess of 1000 tons annually (including unofficially smuggled gold) with negligible local production.[3] The annual gold imports are around 50 billion US$ next only to crude oil imports widening the trade deficit.[4]
Gold
The BIS system of hallmarking of gold jewellery began in April 2000. The standard specifications governing this system are IS 1417 (grades of gold and gold alloys, jewellery/artefacts), IS 1418 (assaying of gold in gold bullion, gold alloys and gold jewellery/artefacts), IS 2790 (guidelines for manufacture of 14, 18 and 22 carat gold alloys only ), IS 3095 (gold solders for use in manufacture of jewellery).[5]
The BIS hallmark
BIS hallmark for gold jewelry consists of several components:
- The BIS logo
- Purity of Gold either one of this 22K916 Corresponding to 22 Carat, 18K750 Corresponding to 18 Carat and 14K585 Corresponding to 14 Carat.
- 6 digit alphanumeric HUID- HALLMARK UNIQUE IDENTIFICATION
Silver
BIS introduced hallmarking for silver jewelry in December 2005 under IS 2112, the standard specification for 'Hallmarking of Silver Jewellery/Artefacts'.
Assaying & Hallmarking Centres
The testing of the jewelry as well as the marking is done in approved Assaying & Hallmarking Centres across the nation. These are private undertakings approved as well as monitored by the BIS.
