Some mines have become legendary, not only for the exceptional quality of their stones but also for the stories they carry and the treasures they have produced.
From ancient India with the mythical Golconda mine, to South Africa with the spectacular Cullinan, and not forgetting Australia with the enigmatic Argyle, these mining sites have left an indelible mark on the history of gemology. Each has offered the world diamonds of unique beauty and characteristics, becoming symbols of power, love, and eternity.
In this article, we invite you to dive into these emblematic locations to understand why they hold a special place in both the jewelry and scientific worlds.
Why have some mines become legendary ?
The historical importance of diamonds
Legendary mines owe their fame not only to the quantity or quality of the stones they produce. They have often yielded diamonds that have left a mark on history: royal crown jewels, stones with tumultuous destinies, or gems that became symbols of a reign or dynasty. Diamonds like the Koh-i-Noor or Cullinan I are not mere minerals, but living witnesses of human history.
The rarity and exceptional colors
Each legendary mine is associated with a specific gemological signature. Golconda is renowned for the almost unmatched purity and transparency of its stones. Argyle revealed to the world the most intense and rare pink diamonds ever discovered. As for Cullinan, it entered legend with the discovery of the largest known rough diamond. These unique features make these sites essential references for gemologists and collectors.
The symbolic and cultural value
Diamonds from these mines are more than just their market value. They carry powerful symbols: eternal love, royal power, prestige, and heritage. In many cultures, owning a diamond from such an origin is like holding a fragment of history and legend. These stones embody both the brilliance of nature and the legacy of entire civilizations, which explains why they continue to inspire admiration and desire.
The Golconda mine: the cradle of historical diamonds
A unique terroir in India
Located in the Deccan region of India, the Golconda mine is considered the cradle of historic diamonds. Exploited since ancient times, it was for several centuries the only known source of diamonds in the world. Kings, emperors, and merchants competed for these exceptionally high-quality gems, making Golconda a central hub for the precious stones trade in Asia. Today, the name Golconda has become synonymous with perfection and exclusivity in the jewelry world.
Famous diamonds (Koh-i-Noor, Regent, Hope...)
Golconda’s diamonds became legendary through famous gems that still adorn royal treasures today. The Koh-i-Noor, a coveted and cursed stone, is part of the British crown jewels. The Regent, discovered in the 17th century, is kept at the Louvre Museum in Paris and is considered one of the most perfectly cut diamonds ever. As for the Hope, famous for its deep blue color and the legends of curse surrounding it, it alone exemplifies the unique character of Golconda gems.
Gemological features: purity, lack of inclusions, exceptional transparency
Golconda diamonds are renowned for their crystalline purity and near-total absence of inclusions, a rarity in the gemological world. Their transparency and extraordinary brilliance are often described as “crystal water.” These natural qualities explain why these stones are still studied and admired today as models of perfection, serving as true benchmarks in the classification and evaluation of diamonds.
The Cullinan Mine: The Giant of South Africa
Discovery of the largest rough diamond in the world
The Cullinan mine, located near Pretoria in South Africa, was discovered in 1902. However, it entered history definitively in 1905, when a 3,106-carat rough diamond was unearthed—the largest ever discovered. This spectacular find immediately placed Cullinan among legendary mines and continues to inspire fascination and admiration.
Cleaving and cutting of the legendary stones (Cullinan I and II)
The Cullinan rough diamond was so massive that it took several months to plan its cleaving. Divided into multiple gems, it produced exceptional stones, including Cullinan I (or the “Great Star of Africa”), a 530-carat diamond set in the British royal scepter, and Cullinan II, a 317-carat diamond set in the imperial state crown. These two gems, among the largest cut diamonds in the world, remain symbols of Cullinan’s grandeur.
Gemological characteristics: size, purity, and whiteness of the stones
Beyond its record size, Cullinan diamonds are distinguished by their exceptional whiteness and remarkable purity. Many belong to the rare Type IIa category, free of nitrogen, which gives them their particular transparency and brilliance. These gemological qualities make Cullinan a reference site for gemologists and a major landmark in diamond history.
The Argyle Mine: The Kingdom of Pink Diamonds
Location in Australia and economic importance
Located in the remote Kimberley region of Western Australia, the Argyle mine was discovered in 1979 and began operations in 1983. It quickly became one of the most important diamond mines in the world, not only in terms of production volume but also for its major economic role in Australia. For several decades, Argyle produced over one-third of the world’s diamonds by volume, helping to establish Australia as a key player in the diamond industry.
Pink diamonds and their extreme rarity
Argyle became legendary primarily for its pink diamonds, considered the rarest and most valuable in the world. These gems are distinguished by their exceptional color intensity, ranging from soft pink to deep red. Less than 1% of the diamonds extracted at Argyle possessed this unique color, giving them an inestimable value. Their rarity has driven their prices far beyond those of colorless diamonds, generating immense interest among collectors and major jewelry houses.
Recent closure of the mine and consequences on the market
In November 2020, the Argyle mine officially ceased operations, marking the end of an era. This closure had an immediate impact on the market, further reducing the availability of pink diamonds and reinforcing their status as exceptional investment stones. Since then, diamonds from Argyle have become even more sought-after, enhancing their legendary aura and importance in the history of gemology.
Gemmological characteristics: intense colors, shades of pink to red
Argyle diamonds are distinguished by their intense, saturated hues, resulting from a unique geological process. Unlike colored diamonds whose shades come from chemical impurities (such as nitrogen or boron), Argyle’s pink diamonds owe their color to a distortion of the crystal lattice, which alters how light is absorbed. This rare phenomenon explains the range of colors from light pink to vivid red, giving these stones a unique and instantly recognizable identity.

Jwaneng and Orapa (Botswana): massive production and quality
Botswana is home to two of the most productive mines in the world: Jwaneng and Orapa. Jwaneng, nicknamed the “Mine of Riches,” is renowned for the exceptional quality of its diamonds, while Orapa holds the record for the largest surface area. Together, they make Botswana one of the world’s leading diamond producers, securing the country a central economic role and a prominent place in the international market.
Kimberley (South Africa): the "Big Hole" mine and the modern history of diamonds
The Kimberley mine, with its immense crater known as the Big Hole, marked the beginning of the modern diamond era in the 19th century. It was here that large-scale industrial mining was born, transforming the global economy and giving rise to major diamond companies. Today, Kimberley remains a symbol of mining history and the transition from artisanal extraction to an organized industry.
Mirny (Russia): impressive crater and industrial and gem diamonds
In Russia, the Mirny mine, located in Siberia, impresses with its gigantic crater visible from space. Discovered in the 1950s, it enabled the USSR to become a major player in the diamond market.

Its scale and history make it one of the most iconic mining sites in the world.
Legacy of mines and modern know-how
What these mines have contributed to gemology
The mines of Golconda, Cullinan, and Argyle are not just extraction sites: they have shaped the history and science of diamonds. Their discoveries have allowed gemologists to study exceptional stones, refine gemological classifications (purity, color, atomic types), and perfect cutting techniques. They have become scientific and aesthetic benchmarks, serving as models in evaluating diamond quality.
The evolution towards enhanced traceability and ethics
While these mines became legendary for the beauty of their stones, they also remind us of the importance of responsible mining. Today, the diamond industry has evolved toward greater transparency and ethics. The Kimberley Process and new technologies such as blockchain aim to ensure diamond traceability and prevent the trade of stones from conflict zones. This evolution reflects a commitment to preserving the cultural and symbolic value of diamonds while respecting social and environmental concerns.
