The 3 Billion Year Journey

Diamonds are the ultimate survivors of earth's violent history. Most natural diamonds were formed at depths between 150 and 250 kilometers in the Earth's mantle, under temperatures exceeding 1000 degrees Celsius.

The Volcanic Transit

They are brought to the surface by rare, deep-source volcanic eruptions known as Kimberlite pipes. These eruptions happen at supersonic speeds, carrying the ancient stones safely to the crust before they can be vaporized by the heat.

"To hold a diamond is to hold a fragment of the earth as it was 3 billion years ago."

Verified Science

Recent research shows that diamonds are not just older than many stars in our galaxy, but they also act as chemical "time capsules," preserving rare minerals that exist nowhere else on the planet's surface.
