These discoveries keep us on the edge of anticipation, as we are constantly poised for new, larger, and higher-quality diamonds to emerge, driving the world of gemology toward its next exciting breakthrough.

The Largest Diamond Ever Discovered: The Cullinan Diamond

The title of the largest diamond ever found belongs to the Cullinan Diamond, an extraordinary gem weighing a massive 3,106 carats when it was unearthed in South Africa in 1905. Named after Sir Thomas Cullinan, the owner of the Premier Mine where it was discovered, the Cullinan Diamond’s sheer size made headlines around the world, and it remains unmatched in terms of its carat weight and overall significance.

This rough diamond was so large that it had to be cut into several smaller, yet still incredibly valuable, gems. The largest cut from the Cullinan is known as Cullinan I, or the Great Star of Africa, and weighs 530.2 carats. Today, the Great Star of Africa is set in the head of the Sovereign’s Sceptre with Cross, part of the British Crown Jewels.

The Cullinan Diamonds: A Royal Legacy

The Cullinan Diamond didn’t just produce one notable gem—it was cut into nine major diamonds, each with its own story and importance. These diamonds became part of the British Crown Jewels and the private collection of the British royal family. Among them:

  • Cullinan I (The Great Star of Africa): The largest of the Cullinan stones, set in the Sovereign’s Sceptre.
  • Cullinan II (The Second Star of Africa): Weighing 317.4 carats, this diamond is set in the Imperial State Crown, another essential part of the British Crown Jewels.

Other Cullinan diamonds are also part of the Crown Jewels or are worn by members of the royal family, cementing the legacy of this extraordinary find.

A New Discovery: Lucara's Massive Diamond Find

On August 22, 2024, Lucara Diamond Corp. announced an exciting new discovery—a massive 2,492-carat diamond found at the Karowe Mine in Botswana. This discovery ranks as the second-largest diamond ever found, and its size has taken the diamond industry by storm.

This yet-to-be-named diamond was unveiled in a special ceremony in Gaborone, with Botswana's President Mokgweetsi Masisi as one of the first to hold it. The stone is remarkable not only for its size but for the advanced X-ray transmission technology that made its recovery possible. It continues the Karowe Mine’s reputation as one of the premier sources of large diamonds, with previous finds like the Lesedi La Rona and Sewelo diamonds.

While the diamond is still being assessed for its quality, its sheer size and potential place it among the greats, contributing to Botswana’s reputation as a leading source of some of the world's largest gems.

Other Famous Large Diamonds

While the Cullinan holds the record for the largest diamond ever discovered, several other enormous diamonds have left their mark on history. Let’s take a look at some of these famous stones:

1. The Excelsior Diamond

Before the discovery of the Cullinan, the Excelsior Diamond held the title of the largest known diamond. It was found in South Africa in 1893 and weighed 995.2 carats. Like the Cullinan, it was cut into smaller gems, with the largest being the Excelsior I, weighing 69.68 carats.

2. The Star of Sierra Leone

Discovered in 1972 in Sierra Leone, this diamond weighed 968.9 carats. The Star of Sierra Leone was later cut into multiple stones, with the largest piece weighing 143.2 carats. This diamond remains one of the largest and most famous gems in history.

3. The Lesedi La Rona

The Lesedi La Rona is the largest diamond discovered in recent times, found in 2015 at the Karowe Mine in Botswana. Weighing 1,109 carats in its rough state, it is the largest diamond discovered since the Cullinan. The diamond was eventually cut into smaller gems, and its name means “Our Light” in the Tswana language.

4. The Golden Jubilee Diamond

The Golden Jubilee Diamond, discovered in South Africa in 1985, weighs an impressive 545.67 carats after cutting. It is currently the largest faceted diamond in the world and was presented to the King of Thailand for his 50th coronation anniversary, symbolizing its significance.

How Do These Diamonds Compare?

While each of these diamonds is monumental in its own right, the Cullinan Diamond still stands as the largest ever found. However, the way diamonds are cut can impact their final size. The Golden Jubilee Diamond holds the title for the largest polished diamond, while Cullinan I remains the largest faceted clear-cut diamond.
