What is the Largest Diamond Ever?
The Cullinan Diamond is the largest diamond ever known to exist. It was found in 1905 in the Premier Mine in South Africa. In its rough form, the Cullinan weighed a staggering 3,106 carats. This exceptional gemstone was eventually cut into several polished diamonds, including Cullinan I, the Great Star of Africa’s largest clear-cut diamond. These diamonds now form part of the British Crown Jewels, thus cementing the Cullinan’s place in history as an extraordinary discovery.
Details of the Cullinan Diamond
The Cullinan diamond is the largest gem-quality rough diamond ever found, measured at 3,106 carats in its uncut form. After its discovery, the diamond was cut into nine notable pieces, the most significant being Cullinan I, which is deemed the second-largest colorless diamond. This diamond weighs approximately 530.2 carats and is called the Great Star of Africa; it is set in the Sovereign's scepter with Cross. Cullinan II, which is 317.4 carats, is mounted on the Imperial State Crown, which is made of Gold. The astonishing size and clarity of these gemstones, alongside their historical significance, mark the Cullinan as one of the most important diamond discoveries in history.
The World's Largest Diamonds Throughout History
The Lesedi La Rona is another astonishing diamond discovered in Botswana in 2015. It is the largest diamond found in over a century and the second largest in history, surpassing 1,109 carats in its rough form. Due to its massive size and structure, the diamond was eventually cut into smaller stones. The Lesedi La Rona is celebrated with Cullinan for its remarkable clarity and quality, solidifying its position among the most crucial diamond discoveries ever.
How the Largest Diamonds are Measured
Determining the size of the largest diamonds entails an intricate process requiring precision methodology and cutting-edge technology. Usually, the weight of a diamond is measured in carats, and for all diamonds, including flawless diamonds, one carat is equivalent to 0.2 grams. The golden jubilee diamond is appraised using this valuation method. Extremely cleaved diamonds like Cullinan and Lesedi La Rona require maximum precision appraisal using sensitive digital scales that ensure equal precision.
Beyond weight, a gemologist evaluates the diamond's proportions, clarity, chromaticity, coloration, and potential grade of being cut using optical proportion scopes and laser 3D imaging software. These technologies create a detailed rough sapphire model that aids experts in numerical precision in diamond and yield calculations without compromising the stone's integrity.
Moreover, atomic structure inclusions can assess diamond valuation and classification using scientific x-ray fluorescence and spectroscopy. Methods such as these are critical when ensuring a diamond or gem's historical value alongside preserving its gemological significance. While all the world's diamonds are categorized alongside the largest diamonds, these methods ensure the precise valuation of a history-filled masterpiece.

What Are Other Famous Diamonds in the World?
The Excelsior Diamond and Its Historical Context
Found in 1893 in the Jagersfontein Mine of South Africa, Excelsior Diamond was a wonder weighing 995 carats, and at that moment was the largest diamond in the world. Its name, “Excelsior,” refers to being elevated, representing its value perfectly. It was found to be bluish white, which made it a splendid treasure for a diamond.
Unlike other famous diamonds, the Excelsior Diamond was disassembled differently into two main sections of ten dominant stones of different sizes, alongside multiple fragments. It is nearly carbonado-like in its smashing approach. The biggest stone, Excelsior I, ended up being 69.68 carats and having a pear-shaped cut. While the reasoning for splitting the diamond is still undetermined, it aided in providing commercial value and ease of obtaining the resulting stones.
The Excelsior stones ended up in both private collections and commercial pieces, with some auctioned alongside Graff diamonds. The diamond's historical context mentions its importance in the trade practices of the late 19th century, not to mention its geological significance. Today, the legacy of Excelsior Diamond still serves as a testament to the exquisite gifts of nature and the evolving skill in the artistry of gem cutting.
Discoveries from the Karowe Mine in Botswana
Lucara Diamond Corporation’s Karowe Mine in Botswana is famous for yielding the most significant and finest diamonds worldwide. Since the mine was opened in 2012, it has produced several exceptional gemstones, including some gemstones weighing more than 1000 carats. Moreover, the mine is known for producing Lesedi La Rona in 2015, a 1,109-carat Type IIa diamond noted for its clarity and size. It drew international attention as the second-largest gem-quality diamond recovered in the last century.
In 2019, the Karowe Mine added to its collection of remarkable finds by discovering an even larger diamond, the Sewelô at 1,758 carats. While Sewelô does mean ‘rare find’ in Setswana, the diamond itself is also dubbed ‘rare find.’ Unlike Lesedi La Rona, Sewelô is covered in black carbon, which does shield its internal qualities. Nevertheless, both finds ensured Karowe Mine its prominent place as a cornerstone in Botswana’s diamond industry.
The Karowe Mine's success stems from newer X-ray transmission technologies in the diamond mining industry, which garner large diamonds from the mine, increasing yield. These recent changes aid in targeting valuable stones and improve operational productivity. As work and exploration progress in the area, the Karowe Mine remains a mainstay of the Botswana economy, leading the world in sustainable diamond mining.
The Millennium Star Diamond and Its Modern Significance
The Millennium Star Diamond ranks among the finest gemstones globally, known for its exquisite beauty, exceptional quality, and rarity. This butterfly-shaped diamond weighs 203.04 carats and is a Type IIa diamond, meaning it has incredible clarity and is devoid of any color impurities. It was found in the Democratic Republic of Congo (commonly known as DRC) in the 1990s, and it is without a doubt one of the most famous gemstones due to its pear shape and unmatched brilliance. To this day, Millennium Star remains an iconic construction of mastery which epitomizes luxury and skill, serving as a benchmark in precision cutting akin to the famed diamonds from Karowe. Its importance goes far beyond allure, underscoring strides made in the artistry and science, particularly regarding the largest alluvial diamonds.
