What is the Uncut Cullinan Diamond?

The Cullinan Diamond, discovered on January 26, 1905, in the Premier No. 2 mine in Cullinan, South Africa, remains the largest gem-quality rough diamond ever found. Its sheer size is staggering: it weighed an astonishing 3,106.75 carats in its uncut state, which is equivalent to about 1.37 pounds or 621.35 grams. To put this into perspective, most gem-quality diamonds weigh between 0.5 and 2 carats. The discovery sent shockwaves through the mining world and beyond, capturing the imagination of people globally. The uncut Cullinan diamond was so large that it was difficult to handle, and its rough, crystalline surface hinted at the immense potential it held within.

The geological conditions under which such a massive diamond formed are extremely rare, involving immense pressure and heat deep within the Earth’s mantle over billions of years. Its journey to the surface, likely through volcanic activity, is a perilous one, and finding such a large, intact crystal is an event of astronomical odds. When found, its appearance was described as being like a flawless, clear piece of glass, albeit with a rough, unpolished exterior. Its discovery was accidental, found by a mine security manager named Frederick Wells who spotted a glint of light near the mine’s surface.

The Significance of its Uncut State

The value of a diamond is typically assessed based on the Four Cs: Carat (weight), Cut, Color, and Clarity. However, with a stone as unique as the uncut Cullinan diamond, its raw, uncut state holds immense historical and geological significance. Before any cuts were made, the stone was a direct testament to the earth’s incredible mineral wealth. Its uncut form represented potential, a raw block of perfection from which multiple, significant gemstones could be fashioned. The decision of how to cut such a historic stone was a monumental task, involving considerable debate and expertise. The fact that it was found in such a pristine, uncut state adds a layer of mystique and historical importance that polished diamonds, while beautiful, cannot replicate.

Geological Formation and Rarity

The formation of diamonds requires specific conditions: carbon atoms subjected to extreme pressure and high temperatures, typically found at depths of 150-200 kilometers (90-120 miles) below the Earth’s surface. These conditions are met in the Earth’s mantle. When kimberlite pipes, which are volcanic formations, erupt from the mantle to the surface, they can bring diamonds with them. The Cullinan diamond likely formed under such conditions and was brought to the surface through a kimberlite eruption. The rarity of finding a diamond of this size is astronomical; it’s estimated that only one in a million diamonds are of gem quality, and of those, very few reach weights over 100 carats. The Cullinan diamond, at over 3,000 carats, is in a league of its own, making its uncut state a subject of immense scientific and commercial interest, with potential markets worldwide, including those within Saudi Arabia.

The Journey from Uncut to Masterpiece: The Cullinan Diamonds

Upon its discovery, the uncut Cullinan diamond was deemed too large to be processed as a single stone. The South African government acquired it, and it was presented to King Edward VII of the United Kingdom. After much deliberation, the difficult task of cleaving and cutting the massive stone was entrusted to the renowned Asscher Brothers of Amsterdam. The cutting process itself was fraught with tension and required immense skill and precision. The original rough diamond was cleaved into nine major stones and numerous smaller ones. These resulting diamonds are known as the Cullinan I (Star of Africa), Cullinan II, Cullinan III, and so on.

The Cullinan I, also known as the Great Star of Africa, is the largest of the cleaved stones, weighing 530.4 carats. It is a flawless, colorless diamond of exceptional clarity and brilliance, making it one of the most stunning diamonds in the world. It was cut from the largest piece of the original rough diamond. The Cullinan II, weighing 317.4 carats, is the second-largest stone and is mounted below the Cullinan I in the Imperial State Crown of the United Kingdom. These legendary stones are housed in the British Crown Jewels, symbolizing a significant part of royal history.

Cullinan I: The Great Star of Africa

The Cullinan I, or the Great Star of Africa, is arguably the most famous diamond ever cut from the original rough stone. Its sheer size, 530.4 carats, makes it the largest clear cut diamond in the world. It was cut into a pear shape with 74 facets, designed to maximize its brilliance and fire. Its flawless nature and colorless grade (D color) contribute to its unparalleled beauty and value. It is currently set in the Sovereign’s Sceptre with Cross, one of the most significant pieces of the British Crown Jewels. The diamond’s sparkle is said to be visible from a great distance, a testament to its extraordinary quality and size.

Cullinan II and Subsequent Stones

The Cullinan II, weighing 317.4 carats, is cut into a square cushion shape with 64 facets. It is renowned for its exceptional clarity and near-colorless appearance. As mentioned, it is famously set in the Imperial State Crown, worn by Queen Elizabeth II during state occasions. The other major stones include Cullinan III (94.4 carats, pear shape), Cullinan IV (63.6 carats, square cut), Cullinan V (18.8 carats, heart shape), Cullinan VI (11.5 carats, marquise shape), Cullinan VII (8.8 carats, navette shape), Cullinan VIII (6.8 carats, cushion shape), and Cullinan IX (4.39 carats, pear shape). These stones, while smaller than the first two, are still significant in size and value, showcasing the incredible potential of the original uncut diamond. Many of these are part of the personal jewelry collection of the British Royal Family.
