The spectacular fancy intense stone weighs 37.3 carats.
David Bennett, chair of Sotheby’s international jewellery division, said: “The discovery of any pink diamond is exceptional, but 'The Raj Pink’'s remarkable size and intensity of colour places it in the rarefied company of the most important pink diamonds known.”
The record for any diamond is $71.2m, set for the enormous 59.6 carat CTF Pink (formerly the Pink Star) in April this year.
