The Black Korloff

The Black Korloff fascinates by its size, the intensity of its natural color and its enigmatic history.


A 200-carat rough diamond 
cut into an extraordinary 
88-carat brilliant jewel. 



The Korloff Noir’s size and history, along with the intensity of its intriguing natural colour, never cease to fascinate.
Legend has it that this extraordinary jewel brings good luck and protection to whoever had a chance to admire it.

Owned by the Maison for over 40 years, the Korloff Noir is considered to be the largest brilliant-cut black diamond in the world.
Until now, it has been safely stored in the Maison’s safe.




But for the first time in its history, this exceptional diamond

This way, Korloff can share this legendary black diamond with the world
and allow people to experience its true beauty.

From stardust to diamonD.

This gemstone with its unique reflections owes its intense black hue to the presence
of graphite or hematite, which absorbs the light and give the stone its captivating aura.
For centuries, the black diamond was not considered an object of desire.
Initially mistaken for coal by the Portuguese living in Brazil who discovered it
in the 18th -19th century and called it “carbonado”, it is now considered
one of the world’s most sought-after and enigmatic precious stones.

Its origin remains shrouded in mystery for scientists. Although white and coloured
diamonds are associated with kimberlite and volcanic rocks that carry diamonds from
the Earth’s mantle, no black diamond has ever been found in kimberlite.
Another key difference is age:  white and coloured diamonds date back about
one billion years, while black diamonds are much older - about four billion years old.
Lastly, its carbon composition is different to that of other diamonds.

Recent research suggests that this stone was formed directly in interstellar clouds
rich in carbon and hydrogen during explosions of stars into supernovas…
whose fragments later fell to Earth.  

The black korloff IS NOW on display at SHANGHAI FOR THE CIIE eVENT.
