Rare blue diamondset to fetch £3.8m
A rare internally flawless blue diamond is expected to fetch up to £3.8m when it is sold at auction next month.
The 5.16-carat, pear-shaped stone, which is set in a ring, is the first blue diamond from the De Beers Millennium Jewels collection to go under the hammer. It was among 12 stones displayed at the former Millennium Dome in 2000 and will be sold by Sotheby’s in Hong Kong on April 7.
