The Queen owns the world’s biggest diamond and it’s worth millions

THE Queen has an impressive jewellery collection filled with pearls, rubies, emeralds and sapphires - but she also owns the world’s biggest diamond. 

The monarch is the proud owner of the Cullinan Diamond, which weighed a whopping 3,106 metric carats before it was cut. 

The giant diamond, sometimes referred to as the First Star of Africa, was discovered in South Africa in 1905, and was named after the mine’s owner, Thomas Cullinan. 

After the rare stone was found, it was presented to King Edward VII in 1907 by the Government of the Transvaal, in a bid to heal rifts after the Boer War. 

The King received the diamond for his 66th birthday, and was so afraid the stone would be stolen he arranged for a decoy to be delivered. 

The impressive stone was expertly cut, and produced nine large diamonds, referred to as Cullian I, II, III - all the way to number nine. 

Despite the original stone being split into nine numbered diamonds, and other fragments, each is still worth millions. 

Cullinan I alone is estimated to be 530 carats and worth a staggering £40.9 million. 

Following King Edward’s death in 1910, King George V had the largest stone, Cullinan I, set into the Sovereign's Sceptre, which dates back to 1661.

But the diamond is so heavy the 17th century sceptre, which the Queen held for her coronation in 1953, had to be altered to accommodate it. 

The t said: “The diamond is so large that the sceptre had to be reinforced to take its weight.  

“Nevertheless, the structure which holds the diamond is hinged, so the stone can be removed and worn separately if desired.”
