Most expensive Fancy Orange diamond sold at auction

A vivid Fancy Orange diamond sold for 32.6 million Swiss francs ($35.5 million, £22 million) at Christie’s International auction house in Geneva, Switzerland, on 12 November 2013. The diamond had previously been with the same anonymous owner for at least 30 years. The 14.82-carat pear-shaped stone’s price works out as $2.4 million per carat, which is a record for any coloured diamond at a public sale. This beautiful stone is also the largest known vivid Fancy Orange – orange-coloured diamonds being far rarer than their white, pink and yellow counterparts.
