Coloured diamonds remain “highly desirable”, according to auction house Sotheby’s following its recent jewellery sale in Geneva.
Leading the show was a 17.07-carat emerald-cut Fancy Intense Pink diamond that soared over its pre-sale estimate of 11.81m to 14.76m Swiss Francs (£9.5m-£11.8m) to sell for 20.8m Swiss francs (£16.7m).
A new auction record was set for any Fancy Light Pink Diamond when a pear-shaped stone weighing 40.30 carats was purchased for £6m.
Demand was also seen for blue diamonds as a Fancy Deep Blue diamond ring sold for £11m – a new record for a deep blue diamond of any kind – and a Fancy Light Blue diamond sold for £1.7m, also setting a new record.
Meanwhile, the exceptionally rare ‘Sky Blue Diamond’ – a Fancy Vivid Blue diamond weighing 8.01 carats – sold for £13.7m.
David Bennett, worldwide chairman of the company’s jewellery division, said: “The very best coloured diamonds of all hues remain highly desirable, but tonight pink and blue were undoubtedly the hottest colours accounting for many of the top prices this evening.”
