The world's rarest diamonds available to buy


The Pink Legacy


Weighing in at 18.96 carats, the Pink Legacy diamond will be the larges Fancy Vivid pink diamond ever offered at auction by Christie's when it comes up for sale on November 13, 2018 in Geneva. Graded Type IIa, a classification earned by less than 2% of diamonds, and boasting a colour and clarity typically only seen in diamonds weighing less than a carat, the Pink Legacy is descended from the Oppenheimer family and valued in the region of $30 to 50 million. The closest comparison seen at auction is the Pink Promise - a 14.93 carat Fancy Vivid pink diamond which sold at Christie's for $32.48 million in 2017.

Lesedi La Rona rough diamond

The Lesedi La Rona rough diamond

At a huge 1,109 carats, the tennis-ball sized Lesedi La Rona rough diamond was first honoured with its very own auction at Sotheby's London on June 29, 2016 but, after failing to reach its minimum, has recently been acquired by British fine jewellery house Graff in a deal valued at $53 million. Discovered in November 2015 in the Karowe mine in Botswana, it has already been certified as possessing qualities "commonly associated with Type IIa diamonds" by the Gemological Institute of America and is being hailed as the most momentous discovery since the 3,106 carat Cullinan Diamond was unearthed in 1905.

Although not as large as the Cullinan, the Lesedi La Rona's composition means it has the potential to yield the world's largest top-quality diamond once it has been cut and polished. Now in the hands of one of the world's finest diamond experts, time will tell what Graff's master craftsman are able to create from this stunning stone and what treasures await potential buyers.

Graff Venus


Words by Avril Groom

There are many candidates for the title of the world’s most beautiful diamond but Graff’s newly unveiled Venus is surely a contender. The largest ever flawless, D colour, heart-shaped stone at 118.78 carats, it took specially invented tools to cut it and it is worth every hour of the many months of thought and work that created it.

For an object so clear and pure it has unimaginable depth and warmth. The 300-carat rough was found in June 2015 at Lesotho’s Letšeng mine, in which Graff is a major shareholder. Its superlative quality was immediately apparent and its almost cuboid, slightly pointed appearance suggested a pear-shaped or heart-shaped main stone. The latter was chosen both to avoid flaws that closer inspection revealed and to underline the romantic symbolism of this stupendous gem. After the first polish it was rated internally flawless but Laurence Graff, founder and chairman of Graff Diamonds, took the risk of asking for a second polish to attain the coveted flawless level, losing a fraction of a carat in the process.

The Venus is currently unset, nestling in a beautiful wooden box. No price has yet been mentioned but it is sure to break records. And if this ultimate symbol of love is beyond your means, there are 22 satellite stones, from substantial gems of 15 or 13 carats down to modest examples of one or a half carat, in various cuts. So owning a part of the newest legendary diamond is far from an impossible dream.
