Top-5 Largest Diamonds In The World

The average diamond size that BAUNAT sells in our jewellery is 1 to 3 carats. The biggest diamonds in the world are several times that size, and of inestimable value. Let's introduce you to the top 5 largest diamonds ever.

1. The Cullinan

The Cullinan is considered the largest rough diamond ever found and is the source of 105 famous diamonds, including the famous Cullinan I and the Cullinan II. This diamond was discovered in Premier Mine near Pretoria, South Africa in 1905 and weighed a stunning 3106.75 carat before the diamond was cut into 105 different diamonds by the Asscher brothers from Amsterdam.

2. The Lesedi La Rona

The Lesedi La Rona, or ‘Our Life’ in Tswana (the language of Botswana), is the second-largest colourless diamond in the world. The rough diamond was found in the Karowe mine in 2015 and weighed 1,109 carats. A year later, the rough stone was sold for $53 million.

3. The Excelsior Diamond

With a scale of 995.2 carats, the Excelsior Diamond takes third place in the line-up. Found in South Africa, it took a long time for the diamond to be sold. Apparently, there was no one who could afford it. After some time, it was sent to Amsterdam to be cut into 10 smaller precious stones. The largest diamond, Excelsior I, was eventually sold for $2.64 million.

4. The Star of Sierra Leone

The Star of Sierra Leone of 968.9 carats is the largest diamond ever extracted from the mine with the same name. It was soon sold to Harry Winston for a $2.5 million spot price, who had it cut in 17 separate diamonds. The largest precious stone left was still 54 carats.

5. The Lesotho Legend

This stone, the size of two golf balls, weighs a pretty 910 carats and thus takes fifth place. The diamond is not only very large but also has a D-colour sorting and an IIa clarity score. These are the best scores a colourless diamond can get.

The world's largest heart-shaped diamond

The colorless Internally Flawless diamond of 56.15 carat was originally part of the legendary Cullinan. The diamond was put to auction by Christie’s on Valentine’s Day 2011. That’s where the romantic nickname ‘Love at First Sight’ came from. The current owner paid nothing less than 11 million dollars for it.

The largest diamond in the universe

The largest diamond in the universe is not on Earth, but in space. In 2014, a dwarf star was discovered dotted with diamonds. We'll never be able to use the star to process it into jewellery.

The World's Largest Coloured Diamonds

Three of the five largest diamonds in the world are colourless diamonds. That in itself is not surprising, as most diamonds mined worldwide are colourless diamonds. However, there are several coloured diamonds that are definitely worth mentioning.

The biggest coloured diamond: The Golden Jubilee Diamond

The world's largest coloured diamond was found in 1985: the Golden Jubilee Diamond. It is a brown diamond of 545.67 carats and was discovered in the famous Premier Mine in South Africa. It was only found in 1985 and took over two years to cut the rough diamond into its current shape.
The Daria-I-Noor: the largest pink diamond in the world. – BAUNAT

The largest pink diamond in the world

The largest pink diamond in the world is the Daria-I-Noor. It weighs about 182 carats and is part of the Iranian crown jewels. The diamond was originally found in India. As far as quality is concerned, it's not the best pink diamond. That honour befalls the vivid pink diamond Pink Star.

The largest blue diamond in the world

The world's largest blue diamond was discovered in Botswana in April 2019. The rough diamond weighed 41 carats, the cut stone weighs 20 carats. This stone was named the Okavango Blue, after the Okavango Delta in Botswana.
The Tiffany diamond: the largest yellow diamond in the world. - BAUNAT

The world's largest yellow diamond

The famous Tiffany diamond is the largest yellow diamond in the world. It was discovered in 1888 in the mine of De Beers, the largest diamond company in the world. It is the seventh largest coloured diamond in the world. New York jeweller Tiffany and Co bought the exceptional stone that was cut into a pillow shape and bears witness to excellent craftsmanship. But it is the wearers of this expensive gemstone that ensured the diamond became a world-famous diamond. That honour was only bestowed on two women. One was Mrs Sheldon who wore it at the Tiffany Ball in Newport, the other was Audrey Hepburn who shined in the blockbuster Breakfast at Tiffany's in 1961.

Top-5 Most Expensive Diamonds In The World

The largest diamonds in the world are not necessarily the most expensive diamonds. Often, the unique history of diamonds also plays a major role to determine the price. We'll introduce you to the five most expensive diamonds in the world.

1. The Koh-i-Noor

The Koh-i-Noor was found in the Kolkonda mine in India and now weighs 109 carats. Koh-i-Noor means 'mountain of light' in Persian. That name came from the Persian general Nadir Shah who shouted this out when he saw the diamond. How much the Koh-i-Noor is worth, is unknown. This is undoubtedly a diamond of indefinable value. The diamond is now incorporated into the crown of Queen Elizabeth II and can be admired in the Tower of London.

4. The Hope diamond

The Hope diamond worth $350 million cannot be left out in this section. It is the rare blue colour that bestowed the well-deserved fame on the expensive stone. Because the diamond was once owned by Sun King Louis XIV, it was named 'Le bleu de France'. It was only since 1830 that the stone was called the Hope diamond, named after its London owner at the time.
It is said there is a curse on the Hope diamond that brings misfortune to the wearer. The first stories of a possible curse surfaced in 1909.

When Diana died in a traffic accident in Paris in 1997, her son Harry got hold of the engagement ring. He then gave it to his brother William. He completed the circle by asking the hand of Kate Middleton in marriage. As a result, the sapphire engagement ring is still popular today.

The most expensive engagement ring

Beyoncé's engagement ring was not the most expensive diamond ring for an engagement. That honour went to pop star Mariah Carey. She received an engagement ring of $10 million with a 35-carat diamond from her partner James Packer. Despite the expensive engagement ring, the marriage didn't last.
