A diamond the size of a strawberry sold at Chritie's auction house in Geneva last night for a record 20.35m Swiss francs (£13.5m).

The flawless, colourless stone, which once belonged to the Archduke Joseph August of Austria (1872-1962), fetched more than double the price paid for it at auction almost two decades ago.%VIRTUAL-SkimlinksPromo%
