Auktion27.04.2022
The natural exclusivity of these precious gemstones has ignited the imagination of connoisseurs over centuries. Early records can be traced back to the 17th century when Jean Baptiste Tavernier sold a dark blue diamond to King Louis XIV of France, which was originally called the Tavernier Blue, and then the French Blue as a part of the French Crown Jewels.
Impeccable Colour. Impeccable Cut. Impeccable Clarity
Perfect according to every critical criterion, The De Beers Cullinan Blue has achieved extremely high rankings under each of the standards by which the quality of a colored diamond is judged. It has been graded Fancy Vivid Blue by the Gemological Institute of America (GIA) – the highest possible colour grading, awarded to no more than 1% of blue diamonds submitted to the GIA. It also boasts exceptional clarity, having been declared Internally Flawless by the GIA; in addition to which, it was found to have excellent polish and to be of Type IIb, a rare category which represents less than 0.5 % of all diamonds.
Adding to the diamond’s allure is its classic step-cut – a style most associated with white diamonds – that is immensely sought-after in rare colors. According to the GIA Monograph, “achieving a Fancy Vivid color grade in a step cut or emerald cut adds to the rarity, since most other fancy shapes intensify the body color more efficiently in the face-up position than step cuts. To achieve a Fancy Vivid grade with a step cut or emerald cut, the inherent body-color has to be stronger than virtually every other fancy shape.”
Given that diamonds are the hardest material on earth, great skill and precision is needed to cut them. With blue diamonds, the challenge is yet greater: because of their formation, every faceting process of a blue diamond demands extreme care and precision. There is zero tolerance for miscalculation; any minute error would result in a loss of colour and destruction of the beauty.
Most of today’s greatest diamond cutters have learnt their trade from their forebears in an industry that – in spite of the advances of modern technology - still relies to a large degree on craftsmanship that has been handed down through families for generations. To cut a stone of this outstanding importance required a level of expertise and craftsmanship possessed by only a small handful of cutters. The skill with which this step cut was achieved is testament to the impeccable savoir-faire of Diacore’s diamond cutter whose year-long application to the task can, in the words of Wenhao Yu, be likened to the “skill and dedication of the greatest sculptors of art history.”
