What is the largest diamond mine

The 5 largest diamonds in the world

Marilyn Monroe sang “Diamonds are a girl’s best friends” in the musical film adaptation “Blondes preferred” from 1953. Diamonds are immortal and keep their value.

The world's hardest currency still ekes out a niche existence when it comes to financial investments, but diamonds do serve as an investment object despite strong price fluctuations in some cases. Those who want to invest in the long term can be sure: Diamonds are forever.

The top 5 largest diamonds in the world revive the fascination for these immortal gemstones.

5. “Incomparable”: 890 carats

The flawless diamond in the color “fancy brownish yellow” is the largest faceted yellow diamond.

The rough diamond, weighing 890 carats, was found in a pile of rubble by a playing girl in Mbugi Mayi, Democratic Republic of the Congo, in the 1980s. The well-known diamond producer De Beers bought the “Incomparable” and then sold it to the Zale Company's jewelery dealers.

This is where the stone was cut. However, the irregular shape and small cracks caused great difficulties in grinding. A large diamond and 14 smaller diamonds of the highest quality were created. An amazing detail: the colors of the small diamonds range from a light yellow to a shade of brown to colorless.

The attempt to auction the diamond in 1988 ended in fiasco. The minimum price of $ 20 million was not reached and the auction ended without a sale.

4. “Star of Sierra Leone”: 968.90 carats

The third largest diamond was excavated in the Dominica Mine in Sierra Leone in 1972.

Harry Winston, the diamond dealer whose name is only associated with the finest and most valuable pieces of jewelry, bought the “Star of Sierra Leone” and divided it into 17 stones, 13 of which were flawless. The largest flawless stone weighs 53.96 carats, 6 of the pieces were put together to form a brooch (Star of Sierra Leone brooch).

3. “Excelsior”: 995.20 carats

An African miner discovered the stone in Jagersfontein, South Africa in 1893 while trying to lift gravel onto a truck with a shovel. The worker kept his find a secret from the supervisor and handed it over directly to his supervisor. 500 pounds and a horse were the reward for the find.

The blue and white color is just as typical of the Jagersfontein diamonds as the black internal inclusions that tarnish their purity. The name “Excelsior” (roughly: “raised”) can be traced back to the shape of the rough diamond, flat on one side, pointed on the other.

The diamond was split into 21 stones. After being cut, the stones weighed no more than 373.75 carats, which equates to a weight loss of almost 63%. Nevertheless, the result was considered a success.

Today the stone is owned by Robert Mouawad, a well-known jewelry and watch entrepreneur whose family owns one of the world's finest collections of diamonds - including the Excelsior diamond.

2. “Lesedi La Rona”: 1,109 carats

The owner Lucara Diamond ran a competition with a prize money to choose the name for the diamond. The winner was “Lesedi La Rona”, which means “our light” in German. The name comes from the Bantu language Setswana, which speaks 90% of Botswana's population.

The diamond, which is about the size of a tennis ball (65 mm × 56 mm × 40 mm), was discovered in Botswana in 2015. The owner tried to auction it off at Sotheby’s for a minimum price of € 63 million. Despite great excitement, nobody wanted to pay such a sum. After negotiations, the price was reduced to € 45 million.

1. “Cullinan”: 3,106.7 carats

The largest rough diamond ever found, weighing 3,106.7 carats, was excavated in the Premier Mine in South Africa in 1905. The jewel called “Cullinan” (named after the mine owner Thomas Cullinan) was split into 105 stones. Buying and selling parts of this rarest and most valuable diamond is always a spectacle.

The diamond was given to the British King Edward VII in 1907 as a birthday present from the former British colony of South Africa. The stone was brought to Amsterdam for further processing. The cleavage turned out to be difficult due to the hardness of the diamond, but in the end the split into 96 small and 9 large diamonds succeeded.

The large diamond pieces were cut into crown jewels and have been part of the British crown jewels ever since. These are kept in the London Tower.
