Surbhi Prasad The commerce ministry will soon launch a system similar to hallmarking of gold to certify the quality of precious gemstones. \u201cWe want consumers to know the purity of precious gemstones. Right now, there is no proper mechanism to know how testing of precious gemstones is done because of which consumers are misled,\u201d a senior government official said. The department is also urging consumer affairs ministry to amend Bureau of Indian Standards Act. \u201cWe are pushing them to amend it. This will need a few changes in the BIS Act. Currently, there is no provision for hallmarking of gems and precious stones in India. We want this to be mandatory,\u201d the official said, adding that the policy is likely to be in place by 2017-end. The ministry is also mulling a separate accreditation body for gemstones as many private labs claiming to certify these jewels have spread rapidly in the country. There are no government accredited labs to verify precious gemstones, but accreditation by international players including GIA, HRD and IGI is recognised in India. The Gem & Jewellery Export Promotion Council has also set up gemstone certification centres in four cities \u2014 Delhi, Jaipur, Surat and Mumbai. Officials in the commerce department believe that this would further boost gems and jewellery exports from the country. According to data from the Gem & Jewellery Export Promotion Council, India\u2019s gems and jewellery exports in May rose 8% on year to $3.46 billion. For April-May, the exports were up 11% on year at $6.78 billion. During 2016-17 (April-March), the country\u2019s gems and jewellery exports rose 9% on year to $35.55 billion.
