Sotheby's has a distinguished and successful history of selling blue diamonds and in the last three years alone the company has seen three blue diamonds achieve prices that represent more that $1 million per carat: in Hong Kong in October 2007 a fancy vivid blue emerald cut diamond ring weighing 6.04 carats realised $7.9 million; in Geneva in November 2007 a pear-shaped blue diamond sold for $4.7 million; and then in Geneva in May 2008 another pearshaped vivid blue diamond, set as a ring, brought $4.9 million, establishing the new world record price per carat for any gemstone at auction.
