   All that glitters is not gold
  Your wedding jewellery may not be as pure or as precious as you think it is. Several goldsmiths across India have taken to adulterating the precious metal with iridium and ruthenium, and are getting away with it, as until recently the metals failed to show up on all purity checks.

    It's an alchemist's dream, and the practice is becoming increasingly commonplace if you go by the stocks of the `duplicate' metals at even the smallest of karigar workshops. Both iridium and ruthenium belong to the platinum family of metals, and when mixed with gold, do not form an alloy but sit tight in the yellow metal. 
  
Governmen makes hallmarking gold jewellery mandatory
   To protect consumers from unscrupulous jewellers, the government on January 4, 2011 approved a proposal making hallmarking of gold. The hallmarking of gold, which is voluntary in nature at present, is a purity certification of the precious metal. The Bureau of Indian Standards (BIS), under the Consumer Affairs Ministry, is the administrative authority of hallmarking. The Cabinet, headed by Prime Minister Manmohan Singh, cleared the proposal by approving amendments to the Bureau of Indian Standards (BIS) Act, 1986, that aims to expand the ambit of mandatory hallmarking to include more products, including gold, sources said.
   The BIS (Amendment) Bill, will empower the government to bring in compulsory certification regime any article and/or process that it considers necessary from the point of view of health, safety, environment and prevention of deceptive practice, they said. At present, about 77 items, including cement, mineral water and milk products, are certified through mandatory hallmarking under the BIS Act for conformity with expected quality levels.
   The BIS hallmark, a mark of conformity widely accepted by the consumer, bestows the additional confidence to the consumer on the quality of products like gold jewellery.
   Besides mandatory hallmarking, the amendments moved by the Consumer Affairs Ministry also seek to introduce registration of relevant standards as an alternative mechanism to the compulsory certification regime to facilitate growth of sunrise sectors like IT and biotechnology and protect consumers from spurious and substandard imports.
It also aims to strengthen the penal provision for better and effective compliance with the provision of BIS Act.  
   BIS: Hallmarking of gold jewellery 

 
 BIS Hallmarking raised questions by traders
  
"The BIS at present has around 160 hallmarking centres in a country that's home to three and a half lakh jewellers," said Bachhraj Bamalwa, a Kolkata-based retailer and chairman of All India Gems & Jewellery  Federation  (GJF), comprising 1.25-1.5 lakh trade members. "How can BIS implement the proposed law unless it sets up hallmarking
centres across small cities and at district and taluka levels where a majority of gold merchants are located. The distance of each hallmark centre from every location must be specified."
   Self-certification involves a jeweller certifying his own jewellery, with the government periodically collecting samples to authenticate the accuracy of the certification. India on average imports 800 tonne of gold every year. In the September quarter, World Gold Council pegged gold imports at 200 tonne.
   Out of 203 tonne consumed locally, around 60% was in the form of jewellery and the rest gold bars and coins. While most jewellers present in metros and big cities sell only hallmarked jewellery, which assures a consumer of its purity or gold content, many in the outlying areas do not hallmark jewellery.

   Adulteration in gold jewellery alarming
   What makes the adulteration even more alarming is that the metals do not replace silver and copper, which are added to the gold during the jewellery-making process to harden the soft, malleable yellow metal. The two metals manage to camouflage as gold. BIS  tested several pieces of jewellery, and all had some amount of either iridium or ruthenium lurking inconspicuously with the gold. A 22-carat gold bangle bought in  from a century- and-a-half-old jeweller- when tested a had 3% iridium in it. A gold chain bought from a shop in Bangalore when tested at another city-based centre had 2.39% ruthenium, while a pair of earrings from Kerala was found to be adulterated with 4.65% of iridium. On an average, a piece of jewellery or a bar of gold contains nearly 5-6% of the adulterant, and manufacturers- wholesalers and retailers across India-are aware of how rampant this notorious practice is. Consumers, however, are the biggest losers as they have been kept in the dark. 
  "Most machine-made jewellery contain these adulterants. Overnight, these manufacturers hit the jackpot,'' said Suresh Hundia, president of The Bombay Bullion Association (BBA). 
  The situation came to head when several refineries across India noticed that the gold bought from the market, which when melted, contained at least 6% adulterants. "Some refineries complained that a blackish substance kept floating in the aqua regia (mixture of hydrochloric acid and nitric acid, which can dissolve gold). Moreover, if they bought 1kg of gold, they were losing 50-60gm after refinement. At the time, they didn't know where the rest of the gold was getting lost,'' said a Bureau of Indian Standards (BIS) official.
