A 10.1-carat blue diamond will be offered by Sotheby’s Hong Kong at its Magnificent Jewels & Jadeite Spring Sales scheduled for April 5. The De Beers Millennium Jewel 4, an internally flawless fancy vivid blue diamond, is one of the twelve diamonds – 11 blue and one colourless – that form the De Beers Millennium Jewels collection unveiled in 2000. The piece is estimated to fetch US$30 to US$35 million. The largest oval fancy vivid blue diamond ever to appear at auction, it will be exhibited in New York, London, Geneva, Singapore, Taipei and Hong Kong before going under the hammer at the Hong Kong Convention & Exhibition Centre. Three other rare fancy coloured diamonds are also up for sale, including a 4.08-carat fancy vivid orange diamond, a 4.9-carat fancy intense green diamond, and a 10.3-carat fancy vivid yellow diamond. Another highlight of the auction is an emerald and diamond brooch formerly owned by Queen Amelia of Portugal. |  De Beers Millennium Jewel 4 |
