Pink
diamond ring expected to sell for £24millionA rare pink diamond ring is set to be sold for up to £24million - and become one of the most expensive ever.
The 24.78 carat gem, which is cut into a rectangle with rounded corners, was sold by jeweller-to-the-stars Harry Winston more than 60 years ago and has been in a private collection ever since.
It is currently on display at Sotheby's in Hong Kong. The jewel will be shown around the world before being auctioned by Sotheby's in Geneva on November 16 2010.
Sotheby's expert David Bennett said: "During my 35-year career I have had the opportunity to examine many magnificent and rare gemstones. But this stone is one of the most desirable diamonds I have ever seen."
The expected £24million price tag would make it the costliest diamond per carat to be auctioned. The current record-holder is 7.03-carat Star of Josephine, sold for £6million - £853,485 per carat - in May 2009.
