The surfaces of a diamond are visible in a magnifying glass held using tweezers at Serendip Jewellers in the Hatton Garden Jewellery Emporium in London April 2, 2012. A stock market flotation is likely to top the list of options when Rio Tinto reviews the future of its diamond business, as a shortage of heavyweight buyers prompts the miner to turn instead to funds betting on Asia's appetite for luxury. The Anglo-Australian mining giant could add to the allure of an initial public offering by first seeking to merge its diamond operation with another that is on the block from rival BHP Billiton, bankers and analysts said.

Diamonds are displayed at the certification level of the World Diamond Centre in Antwerp February 5, 2009. It wouldn't be fitting to mount a barrage of "sale" and "special offer" signs in the windows of jewellers crowded into Antwerp's diamond square mile. But traders, cutters and retailers say business is terrible. Just a handful of diamonds can be worth a fortune, so the diamond industry -- centred since the 16th century on the Belgian port city of Antwerp -- has for years depended on debt. Now plunging demand, falling prices and lender reticence have left it looking uncomfortably overdrawn. To match feature FINANCIAL-DIAMONDS/ REUTERS/Yves Herman (BELGIUM)
