The Cullinan Diamond: A Gem of Extraordinary Proportions

In 1905, amidst the arid plains of South Africa, history was unearthed in the form of a colossal diamond. This discovery, at the Premier Mine near Pretoria, would forever alter the course of gemology and become a symbol of power and elegance. Known as the Cullinan Diamond, it remains the largest gem-quality diamond ever found, a true marvel of nature.

1. A Chance Discovery

On January 26, 1905, during a routine inspection of the mine, Frederick Wells, the surface manager, spotted a glimmer in the rock face. Upon closer examination, he unearthed a crystal-like stone weighing an astonishing 3,106 carats—the size of a human fist.

Initially, disbelief surrounded the discovery, with some speculating it was merely a chunk of quartz. However, once confirmed as a diamond, the stone immediately drew global attention. It was named after Sir Thomas Cullinan, the mine's owner, as a tribute to his vision in establishing the Premier Mine.

2. A Royal Journey

The Cullinan Diamond's immense value extended beyond its physical beauty. It became a diplomatic gesture of goodwill. In 1907, the Transvaal Colony government purchased the diamond for £150,000 and presented it to King Edward VII as a gift symbolizing unity between South Africa and the British Empire.

Transport Under Cloak of Secrecy

The journey of this priceless gem to England was shrouded in subterfuge. A decoy diamond, heavily guarded, was shipped aboard a steamer to distract potential thieves. Meanwhile, the real Cullinan traveled unnoticed in a simple parcel sent by regular post.

3. The Challenge of Splitting a Giant

The responsibility of cutting the Cullinan Diamond fell to Joseph Asscher, the head of the renowned Asscher Diamond Company in Amsterdam. Known for his expertise, Asscher faced the challenge of a lifetime.

The First Strike

After weeks of preparation, Asscher made the first attempt to cleave the diamond. The steel blade shattered against the unyielding gem, leaving the diamond unscathed. On the second attempt, with precision and controlled force, Asscher succeeded. It is said that he fainted from relief after the diamond split perfectly.

Eight Months of Mastery

The Cullinan was meticulously divided into 9 major stones, 97 smaller brilliants, and a handful of unpolished fragments. Each cut was a triumph of artistry and engineering, preserving the diamond's exceptional clarity and brilliance.

4. The Stars of Africa

The largest stones from the Cullinan Diamond became treasures of the British Crown Jewels, representing the pinnacle of craftsmanship.

Cullinan I (The Great Star of Africa)

  • Weight: 530.2 carats, the largest colorless cut diamond in the world.
  • Placement: Mounted in the Sovereign's Scepter, this breathtaking gem is a centerpiece of royal regalia.
  • Unique Feature: The scepter was specially reinforced to support its weight.

Cullinan II (The Lesser Star of Africa)

  • Weight: 317.4 carats.
  • Placement: Set in the Imperial State Crown, worn by monarchs during coronations and state ceremonies.

Cullinan III to IX

The remaining major stones were set into brooches, necklaces, and other royal adornments. Some are still privately owned by the British royal family, while others remain on public display.

5. A Symbol of Prestige

The Cullinan Diamond is not merely a gemstone but a legacy. Its significance transcends its monetary value, which is estimated at $2 billion today:

  • Historical Value: A symbol of South Africa’s rich natural resources and its connection to the British monarchy.
  • Craftsmanship: The cutting of the Cullinan Diamond set new standards for diamond artistry, inspiring generations of jewelers.

6. Comparing Giants

Though unmatched in size, the Cullinan Diamond shares the stage with other legendary gems:

  • Lesedi La Rona (1,109 carats): Found in Botswana in 2015, it was sold for $53 million.
  • Sewelô (1,758 carats): Unearthed in 2019, it remains a marvel for its industrial applications.
  • Koh-i-Noor (105.6 carats): Smaller in size but steeped in historical intrigue, it complements the Cullinan's legacy as part of the Crown Jewels.

7. Enduring Legacy

More than a century later, the Cullinan Diamond continues to captivate the world. As part of the Crown Jewels, it is displayed at the Tower of London, drawing millions of visitors each year. Its story—a journey from the depths of the earth to the heights of royalty—remains an unparalleled testament to the wonders of nature and human ingenuity.

This is not just the tale of a diamond but a chronicle of discovery, diplomacy, and artistry. The Cullinan Diamond shines as brightly in history as it does in the Crown Jewels, a timeless emblem of majesty and marvel.
