A pink diamond has sold for more than $50m (€44.2m) at a Christie's auction in Switzerland.
The "Pink Legacy" diamond sale is a new world record price per carat for a pink diamond.
According to Christie’s, the diamond was bought by renowned jeweller Harry Winston.
The nearly 19-carat, rectangular-cut stone was the most remarkable offering at the auction house’s autumn jewellery auction in Geneva. It once belonged to the Oppenheimer diamond family, and Christie's says it is among the most chemically pure gems - with little if any nitrogen.
“The saturation, the intensity of this stone is as good as it gets in a coloured diamond,” said Rahul Kadakia, Christie’s International Head of Jewellery.
Christie's chairman for Europe, Francois Curiel, called the stone the Leonardo da Vinci of diamonds.
"The 'Pink Legacy' ... brought this extremely high price of 50 million dollars - so $2.6m dollars per carat, which is a world record price for a pink diamond.”
Mr Curiel said that the previous record was $2.1m per carat, but for a stone that was over 50 carats in size.
