A Fancy Intense Blue diamond which has been held in a private collection for nearly 30 years sold for $3.6 million (£2,685,000), smashing its $2 million high estimate, at Bonhams Fine Jewellery sale in London on September 20. The 4.03-carat pear-shaped diamond, "became the subject of a fierce bidding frenzy before it finally went under the hammer, selling to Graff Diamonds for $853,203 price per carat," the auction house writes. 

The second headline lot also attracted interest from Bonhams' clients during its preview in London, Geneva, New York and Hong Kong. The Fancy Coloured Diamond brooch dates from the mid-20th century and sold for $978,000 (£725,000). The brooch comprised a total of four Fancy Coloured diamonds: a square step-cut Fancy Gray-Blue diamond, weighing 4.83 carats, two Fancy Dark Brown-Greenish Yellow step-cut diamonds, weighing 2.51 carats and 2.38 carats respectively, and a pear-shaped Fancy Pink Diamond, weighing 1.90 carats.
