One of the world's most admired diamonds has been sold at auction for more than 20m Swiss francs ($21m;£13m).
The 76-carat Archduke Joseph diamond, described as internally flawless, comes from India's famous Golconda mines. The diamond was sold to an anonymous bidder by the Christie's auction house in Geneva.
The price was well above the $15m (£9m) pre-sale estimate, and was far in excess of the $6.5m (£4m) it reached when it was last sold in 1993.
"It is a world record for a Golconda diamond and a world record price per carat for a colorless diamond," Francois Curiel, director of the international jewelry department at Christie's, told reporters.
