10 Incredible Coloured Diamonds

Take a look at these amazing coloured diamonds.

10. The Allnatt Diamond

Worth an estimated $3 million, the Allnatt Diamond is a fancy intense yellow example of the gemstone and is 101.29 carats in size.

It’s named after the British businessman Major Alfred Ernest Allnatt, who owned it during the 1950s. Mystery surrounds its origins before he purchased the stone, but it is believed to have been found in South Africa at the site of what is now the De Beers Premier mine.

Allnatt commissioned Cartier to make a flower setting for it. It was sold for $3 million-plus at Christie’s in Geneva in 1996 to the SIBA Corporation.

9. The Moussaieff Red Diamond

This 5.11 carat diamond is valued at $7 million and is a fancy red stone. It is the biggest fancy red ever to be classified but at 5.11 carats, it’s actually quite small compared to some of the other gems on this countdown.

Previously known as the Red Shield Diamond, it was discovered in the River Abaetezinho in Brazil in 1990.
The stone was sold to Moussaieff Jewellers at the start of the new millennium and takes its current name from the company.

8. The de Grisogono Green Diamond

This $7.3 million 25 carat green diamond is a cushion-cut stone which is believed to have originated in South Africa. The stone is said to be the finest modern example of a green diamond.

The stone was put up for sale by Swiss jeweller de Grisogono in 2006 as part of a white gold ring with seven black diamonds.

The stone was owned by Fawaz Gruosi who is believed to have purchased it from a diamond dealer in 1998.

7. Cora Sun-Drop Diamond

Sold at auction for $10.9 million in 2011, just a year after it was found in South Africa, the Cora Sun-Drop Diamond is the world’s most expensive vivid fancy yellow diamond.

The gemstone is pear-shaped and 110.3 carats in size. It went under the hammer at Sotheby’s in Geneva to a mystery telephone bidder.
Because the diamond was new to the market and had no previous owners, this is believed to have further enhanced its value.

6. The Heart of Eternity

The $16 million Heart of Eternity diamond is a 27.64 carat fancy vivid blue, originally discovered in South Africa at the Premier Diamond Mine.

It was one of diamonds on display at the Millennium Dome in London in 2000 that were the subject of a failed heist.

The diamond was cut into its distinctive heart shape by the Steinmetz group. It is currently owned by a mystery private collector.

5. The Wittelsbach Diamond

This royal diamond is a blue stone that is believed to have originated in India. It was once part of both the Bavarian and Austrian Crown Jewels.

But the diamond that exists today is markedly different to the blue stone that was once owned by royalty. It was substantially recut by Laurence Graff, who paid $16.4 million for it in 2008, in order to remove flaws from the stone.

Around three carats were removed from its size to achieve the aim, and the diamond is now 31.06 carats in size.

4. The Pink Star

This vivid pink diamond is valued at $25 million and is 59.60 carats – the largest vivid pink diamond known to exist.

Previously known as the Steinmetz Pink, it was found in De Beers’ South African mine in 1999 and took expert diamond cutters 20 months to cut and shape. It was sold privately to an unknown buyer in 2007 and was sold again at auction in 2013.

Pink diamonds are incredibly valuable due to their extreme rarity.

3. Graff Pink Diamond

This fancy intense pink is 24.78 carats in size and is valued at $46 million. It was once owned by the legendary jeweller Harry Winston.

It was sold at auction by Sotheby’s in 2010 and is now owned by collector Laurence Graff. It has been described as one of the greatest diamonds ever discovered.

The origin of the stone, which is emerald cut and mounted in a ring, is unclear. It belonged to Winston in the 1950s before being sold to a private collector, who is thought to have kept it for more than 50 years.

2. The Hope Diamond

Worth an astonishing $350 million, the Hope Diamond is a blue stone that is 45.52 carats in size and according to legend, it is cursed because so many people associated with it have died.

The Hope Diamond is believed to have been mined in India in the 17th Century and was taken to France, where it was sold to Louis XIV and made into a cravat pin, known as the French Blue. It disappeared during a theft of the French Crown Jewels during the French Revolution and is thought to have been smuggled to England. It’s believed the jewel now known as the Hope Diamond is just a part of the original French Blue.

It was owned by the British Royal Family for a period and ended up in the US at the start of the 20th Century. It was owned for a time by jeweller Harry Winston, who eventually agreed to gift it to the Smithsonian Museum of Natural History, where it is on display in Washington DC.

1. The Ocean Dream Diamond

No precise estimate of the value of this 5.51 carat stone exists but its incredible rarity means it takes top spot in this Billionaires countdown.

The Ocean Dream was the first, and remains one of only a miniscule number, to be classed as fancy deep-blue green in colour. It gained its unique colour after being exposed to radiation over millions of years.

This amazing stone was found in Central Africa and is part of the collection owned by the Cora Diamond Corporation.

So next time you’re shopping for a diamond, don’t automatically look for the brilliant white variety. The rarity of some coloured diamonds means they can be incredibly valuable, as well as incredibly beautiful to look at.
