An exceptionally rare 19-carat pink diamond is set to be auctioned in Geneva, where it could fetch $50m (€44m), setting a new record for a stone of its kind.
The Pink Legacy used to belong to the Oppenheimer family, which for decades ran the De Beers diamond mining company, but auction house Christie’s refuses to say who the current owner is.
Christie’s international head of jewellery, Rahul Kadakia, described The Pink Legacy as “one of the world’s greatest diamonds”.
The rectangular-cut diamond has been graded “fancy vivid” – the highest possible grade of colour intensity.
Christie’s has noted that in the salesroom, fancy vivid pink diamonds over 10 carats are “virtually unheard of” and that only four vivid pink diamonds or over 10 carats have ever been offered at auction.
