The Heritageof De Beers

Since our origins in Kimberley, South Africa, more than 120 years ago, the search for diamonds has taken us from African deserts to the Canadian arctic and the depths of the ocean floor. Along the way we have connected generations of people with one of the Earth's natural treasures, playing our part in countless memorable moments.
