STOCKSHOTS: India's 'Diamond City' Surat in Gujarat. The prospect of fresh G7 sanctions on Russia's diamond trade weighs heavy on India's diamond hub of Surat, already reeling from supply cuts and falling demand. Some 90 percent of the world's diamonds are cut and polished in the bustling port. A world away from the glamourous boutiques of New York or Tokyo, hundreds of thousands of craftsmen sweat over gemstones in around 4,000 workshops in the city, cutting and setting them into sparkling jewellery. In total around a million people, including dealers and suppliers, are involved in the industry in Gujarat, India's westernmost state. Russian mining giants such as Alrosa traditionally accounted for over a third of India's rough diamonds. STOCKSHOTS
