What Are The World's Most Famous Diamonds?

Diamonds are very rare. So rare, in fact, that during all the centuries that men have looked for them only about 400 large ones have been found. Among these is the famous Cullinan diamond, which, in its rough state, weighed 3,106 carats (about 1-1/3 pounds). This was cut into nine large stones and 96 smaller ones. The Star of Africa, which came from the Cullinan, is still the world's largest cut diamond, weighing 530.2 carats.
The Koh-i-noor diamond came into British possession in 1849 after many changes of hands. It weighed 186 carats upon arrival and was thereafter recut to 106 carats. The Koh-i-noor was designed for Queen Mary in 1911 and is the central stone of the queen's state crown.
About two centuries ago a person named Tavernier bought a very rare sapphire-blue diamond. This was sold to Louis XIV and cut into a triangular stone weighing 68 carats. It was stolen in 1792, never to show up again. But in 1830 the 44-1/2-carat Hope diamond appeared on the market. Many people belive it was cut from the larger diamond belonging to Louis XIV.
