The exceptional 122ct rare blue diamond was unearthed at the famous Cullinan mine in South Africa this week. The Cullinan mine is renowned for producing some of the largest gem quality diamonds ever found.
and has earned its place in history with the discovery of the Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106 carats. This iconic stone was cut into the two most important diamonds which form part of the Crown Jewels in the Tower of London - the First Star of Africa, which is mounted at the top of the Sovereign's Sceptre and which at 530 carats is the largest flawless cut diamond in the world, and the Second Star of Africa, a 317 carat polished diamond which forms the centrepiece of the Imperial State Crown.

Cullinan is renowned as a source of large diamonds and frequently yields diamonds larger than 10 carats. Furthermore, it has produced over 750 stones weighing more than 100 carats, 130 stones weighing more than 200 carats, and around a quarter of all diamonds weighing more than 400 carats.

Cullinan is also renowned as the world's most important source of blue diamonds, providing the collection of 11 rare blue diamonds displayed in 2000 at London's Millennium Dome alongside the Millennium Star, which included the fancy vivid blue 'Heart of Eternity' (27 carats).

About Blue Diamonds

Blue diamonds are one of nature's most special treasures. They are so rare that there are no official statistics on their recovery. The natural blue colour is derived from small amounts of the chemical element boron trapped in the crystal carbon structure during their formation.

The incredible rarity of blue diamonds, along with the rich history associated with many of the more important stones, has made them one of the world's most highly valuable and collectable items.

There have been a number of prominent coloured diamond sales over the last six months, including the "Winston Blue", a pear-shaped 13.22 carat stone and the largest flawless vivid blue diamond in the world, which was sold for US$23.8 million by Christie's in May 2014, setting a world auction record of US$1.8 million per carat for a blue diamond. This sets apart blue diamonds as one of the most highly concentrated forms of wealth known to man.
