Employees work at a diamond cutting and polishing factory in the Surat in the western Indian state of Gujarat March 3, 2009. Hundreds of factories shut down in India's diamond hub, as demand for the gems dipped in the United States and Western Europe, leaving more than 100,000 workers without jobs. The woes of Surat reflect a wider downturn for India's export sector, which accounts for a fifth of Asia's third largest economy. Exports have fallen four months in a row and the latest data available shows a slide of 16 percent in January. To match feature INDIA-DIAMONDS/ REUTERS/Arko Datta (INDIA BUSINESS)
