In 2000, De Beers and the Steinmetz Group unveiled 'The Millennium Star', a 203.4 carat, D-colour, internally and externally flawless pear-shaped diamond, arguably the most valuable diamond in the world. It is currently exhibited at the Millennium Dome in London. Nicky Oppenheimer, chairman, De Beers, did not put any value on the diamond but 'The London Evening Star' insured 'The Millennium Star' for 100 million pounds. Even this is believed to be just a fraction of its price. http://timesofindia.indiatimes.com/articleshow/1717224.cms Aug 18 06, 3:36 PM

The Millennium Star was discovered in the Mbuji-Mayi district of Zaire (Democratic Republic of the Congo) in 1990 in alluvial deposits, uncut it was 777 carat (155.4 g). It took over three years for workers of the Steinmetz Diamond Group to produce the classic pear form; the actual cutting was done using lasers. It was first displayed in October 1999 as the centerpiece of the De Beers Millennium diamond collection. There was an attempt on November 7, 2000 to steal the collection. There are some great pictures of it here: http://famousdiamonds.tripod.com/millenniumstardiamond.html Aug 18 06, 5:27 PM

Could be the Cullinan Diamond... The Cullinan Diamond, found by Frederick Wells, surface manager of the Premier Diamond Mining Company in Cullinan, Gauteng, South Africa on 25 June 1905, is the largest rough gem-quality diamond ever found, at 3,106.75 carats (621.35 g). The largest polished gem from the stone is named Cullinan I or the Great Star of Africa (Picture), and at 530.2 carats (106.04 g) was the largest polished diamond in the world until the 1985 discovery of the Golden Jubilee diamond (545.67 cts), also from the Premier mine. Cullinan I is now mounted in the head of the Sceptre with the Cross. The second largest gem from the Cullinan stone, Cullinan II or the Lesser Star of Africa, at 317.4 carats (63.48 g), is the third largest polished diamond in the world and is also part of the British crown jewels, as it forms a part of the Imperial State Crown. Both gems are on display at the Tower of London, as parts of the British crown jewels. http://en.wikipedia.org/wiki/Cullinan_Diamond Aug 18 06, 8:34 PM

The biggest white diamond in the world is part of Britain's Crown Jewels. If ever sold, it would be that (although that will never happen). http://en.wikipedia.org/wiki/Sceptre_with_the_Cross May 12 07, 7:52 AM
