In the first nine months of 2016, five diamonds over 100ct were unearthed. Among the new discoveries this year include a A 404ct, 7cm wide, white diamond was unearthed in Angola. The stone, which measures about 7cm wide, Later named the “4 de Fevereiro”, it was rated as a Type IIa diamond, which means the rough-cut stone contains very little or no nitrogen atoms and is virtually flawless. This stone was one of the 30 largest top quality rough diamonds ever found.

In June, luxury jewellers de Grisogono hailed the stone’s size and perfection. I“It is going to be an exceptional diamond,” says the maison’s founder, Fawaz Gruosi. “Once it is cut, it will be 150 carats; which we can consider it is one of the biggest flawless, clean, beautiful, colourless diamonds in the world.”

The past two years have been decidedly good for big diamonds. They saw the discovery of several new, large stones and luxury jewellers unveiling spectacularly large stones to the public.

In the first nine months of 2016, five diamonds of over 100 carats were unearthed. This year’s new discoveries include a 404ct white diamond in Angola. The stone, which measures about 7cm wide, was

rated as a Type IIa, which means the rough-cut diamond contains very little or no nitrogen atoms and is virtually flawless.

The 404ct diamond is less than half the size of the masterpiece unearthed in Botswana late last year. At over 1,109 carats, the Lesedi la Rona was the largest rough diamond discovered in more than a

century and is roughly the size of a tennis ball.

Still, the Lesedi la Rona would look diminutive against the largest diamond ever discovered. Discovered in 1905, the 3,106ct Cullinan diamond discovered in South Africa and has since been cut into 105

diamonds, including the Great Star of Africa and the Lesser Star of Africa, both of which belong to the British monarchy and are now exhibited in London’s Crown Jewels.

Also discovered in the same week as the Lesedi la Rona was an 813ct diamond since named “The Constellation”.

Said to be the “find of lifetime” by Sotheby’s jewellery division chairman David Bennett, the Lesedi la Rona had been estimated to fetch more than US$ 70 million at a public auction in June by the auction

house’s London headquarters. The stone failed to sell in the June auction, however, with bids topping at US$61 million, which was below the undisclosed minimum reserve price.

While the Lesedi la Rona failed to sell at Sotheby’s June auction, the Constellation has found a happy home. Luxury jewellers De Grisogono unveiled the Constellation in Paris at the Biennale des Antiquaires

decorative arts, collectibles and antique fair in September.

The stone, which is more than 6cm wide, is expected to become one of the world’s largest certified flawless diamonds after the cutting process is complete.

Fawaz Gruosi, founder of De Grisogono, said of the diamond: “As a jeweller I am conscious of the extraordinary responsibility I have to the stone and to the team who have worked so hard to secure it. To be

able to bring my creative skills to the cutting and setting process of such a stone is both an honour and a privilege, and I cannot wait to realise my vision for it.”

The cutting process is expected to be completed by mid-2017.

In June, London-based British multinational jeweller Graff unveiled the “Graff Vendôme”, a magnificent 105-carat D Flawless pear shape diamond. The stone was named in celebration of the brand’s first

store, in Paris’ Place Vendôme, which is home to many of the most venerable jewellers in the world.

The Graff Vendôme was cut from a 314-carat rough diamond named “The Destiny”. The masterpiece is encircled by 12 additional satellite gems, with the most important one weighing 17.10 carats and nine

others being D Flawless. Over many months of execution, the rough stone was cut using lasers and then polished by hand to yield the final outcome. It holds the honour of being the largest cut and polished

diamond of its kind in the jeweller’s 56 year history.
