Hong Kong, 11 mars 2016 – Sotheby’s Hong Kong a l’honneur de présenter le « De Beers Millennium Jewel 4 »un superbe diamantbleu « Vivid Blue », « Internally Flawless » de taille ovale pesant 10,10 carats – le plus grand diamant bleu de taille ovale jamais proposé aux enchères (Est. 235 – 280 millions HK$ / 30 – 35 millions US$)La pierre sera proposée lors de la vente de printemps de Haute Joaillerie (Magnificent Jewels and Jadeite) le 5 avril 2016. Provenant d’une collection privée asiatique, le De Beers Millennium Jewel 4 est la seule pierre de taille ovale parmi les douze diamants rares – onze diamants bleus et un diamant blanc – qui forment la célèbre collection de renommée mondiale : le De Beers Millennium Jewels Collection, dévoilée par De Beers en 2000 pour marquer le début du nouveau millénaire. Chacun de ces douze diamants se démarque par une incomparable intensité et une saturation de la couleur ainsi qu’une brillance exceptionnelles.

Afin de célébrer le millénaire, De Beers, avec The Steinmetz Group, a présenté en 2000 une exceptionnelle collection de diamants rares et importants, les De Beers Millennium Jewels. Une exposition spéciale a été montée dans la célèbre  Millennium Dome à Londres. Constituée au cours de plusieurs décennies, la collection rassemblait un magnifique diamant blanc, le Millennium Star, ainsi que onze diamants bleus de tailles et de formes différentes, pesant en tout 118 carats, chacun taillé et poli à la perfection. Neuf des onze diamants bleus possèdent, selon l’Institut Gémmologique d’Amérique (GIA) la couleur « Fancy Vivid », la plus recherchée pour les diamants. Les deux autres sont certifiés de couleur « Fancy Intense ». Chacune des pierres provient de la mine Cullinan en Afrique du Sud, et chacune est gravée d’un chiffre unique. Depuis la présentation de la collection en 2000, seule une des pierres a été présentée à la vente : le De Beers Millennium Jewel 11, un diamant « Fancy Vivid Blue » et « Internally Flawless » en forme de cœur, pesant 5,16 carats, a été vendu chez Sotheby’s à Hong Kong en avril 2010. 

Blue diamonds of any intensity of colour are amongst the rarest of all gems. Highly saturated blue diamonds over ten carats combined with an Internally Flawless clarity grade are extremely rare. There have been fewer and fewer new rough diamonds discovered over the last decade that produce this colour. Most of the recent diamonds offered for sale in this category are coming from private collections—not diamond mines.”

To be able to unveil not only one diamond but a collection of such rarity that most of us will not see its like again is, I think, the only adequate way to mark the passage of 2000 years of man’s history.”

De Beers Millennium Jewels: A Once-in-a-Millennium Experience
To celebrate the millennium in 2000, De Beers, together with The Steinmetz Group, showcased an exceptional collection of rare and valuable diamonds, namely the ‘De Beers Millennium Jewels’, in a specially designed exhibit at London’s Millennium Dome. Assembled over decades, the collection consisted of the 203.04-carat colourless diamond ‘Millennium Star’ and eleven phenomenal blue diamonds (pictured above) of various shapes and sizes, totalling 118 carats, all expertly cut and polished. Nine out of the eleven blue diamonds have been graded by the GIA as of Fancy Vivid colour, the highest possible colour grading for coloured diamonds, and two of Fancy Intense colour. All of them originate from the Cullinan Mine in South Africa and each was specially inscribed with a De Beers Millennium number using a proprietary branding technique. Since their initial appearance at the Millennium Exhibition in 2000, only one of these diamonds have ever come into the open market, when Sotheby’s Hong Kong sold the ‘De Beers Millennium Jewel 11’, a 5.16-carat Internally Flawless Pear-shaped Fancy Vivid Blue Diamond, in April 2010.

Blue Diamonds.
Extremely rare and highly coveted in history for its captivating blue sparkle, blue diamonds owe their colour to impurities of boron during the stone’s formation, and many are naturally modified with a grey secondary tone, or an uneven saturation with areas of colourless windowing. Blue diamonds make up much less than 0.1 percent of all diamonds recovered at the Cullinan mine, and to discover one annually of quality and size is an extremely unusual occurrence. Very few stones have the intensity or even saturation as these Millennium blue diamonds and it is this combination of colour, saturation and brilliance that make them truly miracles of Nature.
