The Istanbul-based Jewellery City, the world’s largest integrated gold jewellery complex, expects to become fully operational by next year and generate annual revenues of $10 billion, according to reports. Built at an estimated cost of $200 million, the complex will produce 750 tonnes of jewellery per year.%%According to reports, the primary target of the complex, which will integrate manufacturing and marketing operations, was to relocate small and medium factories from the historic Grand Bazaar.%%Around 30 per cent of the 196,000 sq m of workshop area was already operational and another 20 per cent was set to start production in three to four months. But according to data distributed during a news conference, currently only 319 of a total 2,191 sites, or 15 per cent – including shops, offices and production areas – were functioning, the report said.
