The World’s 5 Largest Diamonds

People generally view diamonds in stores, when the diamonds have already been cut, polished, and faceted into small pieces for diamond engagement rings, necklaces, bracelets, and more. However, the beautiful faceted gemstones were cut and polished from much larger diamonds, which I’m sure any woman would love to get their hands on. Let’s take a look at the world’s five largest diamonds. Please note there is a difference between the largest rough diamond and the largest faceted diamond. The following list contains the world’s five largest rough diamonds, listed from smallest to largest, while noting any resulting large faceted diamonds.

1. The Spirit of de Grisogono - The Spirit of de Grisogono first weighed in at 587 carats. It was discovered several decades ago in west central Africa. This massive diamond resulted in the world’s largest cut black diamond, weighing 312.24 carats.

2. The Golden Jubilee – First weighing in at 755 carats, this magnificent brownish-gold rough diamond was discovered in South Africa in 1985. The resulting faceted diamond weighs 545.67 carats, which is currently the largest faceted diamond in the world.

3. The Incomparable – At 890 carats, this rough diamond was a hit when discovered in the Democratic Republic of Congo (formerly known as Zaire). It was studied and cut, ultimately resulting in a beautiful 407.48 carat faceted diamond.

4. Cullinan Diamond(s) – For several decades and until just recently, this rough diamond was the largest in the world, weighing in at a whopping 3,106 carats. It was discovered in Africa. The cutting of this rough diamond resulted in 105 gems, including two famous diamonds: the Cullinan I (or Star of Africa) and the Cullinan II.

• Star of Africa - At 530.20 carats, this pear shaped diamond measures at 53mm x 44mm x 29mm. Its estimated value is over $400 million. It was the largest faceted diamond in the world until the 1985 discovery of the Golden Jubilee diamond.
• Cullinan II - This 317.40 carat diamond is now part of the British crown jewels. It forms a part of the Imperial State Crown.

5. Unnamed Diamond – In 2007, a rough diamond surpassing the massive Cullinan was discovered in the North-West Province of South Africa. The find electrified diamond communities around the world. This rough diamond is believed to at least double the weight of the Cullinan, which means it may weigh almost 7000 carats! While there is still much studying and cutting to be accomplished, this diamond will surely result in a faceted diamond that will exceed the Golden Jubilee as the largest faceted diamond in the world.
