Naturally expressive
Brown diamonds are among the most naturally expressive diamonds found on Earth. Their colour is not added, treated, or enhanced. It is created during the diamond's formation itself.
ORIGIN
Why the world fell for brown diamonds
The beauty of a brown diamond begins long before it reaches the surface. Hidden within every shade is a story millions of years in the making.
Shaped by Pressure
Beneath the Earth's surface, immense pressure subtly alters the crystal structure of a diamond through a process known as plastic deformation. These microscopic distortions alongside trace amounts of nitrogen affect how light travels through the stone. This unique interaction produces the warm spectrum of brown hues found in each stone.
The Result
Some diamonds appear soft and golden, while others display rich amber and cognac hues. No two stones are ever exactly alike. Therefore, every brown diamond is a record of the forces that shaped it over millions of years.
The Argyle Legacy
The mine that shaped the modern brown diamond industry.
Where It All Began
The modern brown diamond industry was transformed by a single discovery in the remote East Kimberley region of Western Australia. What followed redefined how the world viewed brown diamonds.
A Mine Like No Other
For decades, the Argyle Mine produced majority of the world's brown diamonds and played a significant role in shaping the global market for them. Interestingly, the very same mine was also home to most of the world's pink diamonds.
Defining the Spectrum
Argyle introduced the terminology and colour classifications that helped define the brown diamond market. Its C1-C8 grading scale established a common language for describing brown diamonds and remains widely recognised throughout the industry even today.
The End of an Era
When the Argyle Mine closed permanently in 2020, it marked the end of an important chapter in brown diamond history.
