The De Beers Forevermark Exceptional Diamond Collection

Beyond rare, there is only unique.

De Beers Forevermark is built on the promise that each diamond must be beautiful, rare and responsibly sourced. The Exceptional Diamond Collection represents the pinnacle of that promise, containing some of the most exquisite diamonds in the world.

Every year, only a select number of Exceptional Diamonds are discovered. They are kept separate from other diamonds from the very first moment – their carat weight and singular beauty instantly marking them out as truly remarkable.

Each diamond must be at least three carats – though many are much larger – and is accompanied by its own bespoke book which documents key milestones and photography of the diamond’s journey.

An inscription with a meaning

The De Beers Forevermark inscription is a symbol of the De Beers Forevermark promise and guarantees that the diamond is genuine and responsibly sourced. Invisible to the naked eye, the inscription on each Exceptional Diamond carries the De Beers Forevermark icon and a unique identification number that captures several of its key details: the year it was discovered, its rough carat weight, and its polished carat weight. Entirely unique, it is a symbol of the diamond's distinct characteristics and individual journey.

As part of De Beers Group, De Beers Forevermark invests heavily in the wellbeing of the people in their mining communities, and in wildlife conservation on the land around their mines. When you acquire an Exceptional Diamond, you are making a real contribution to this work.

The making of a masterpiece

The potential of an Exceptional Diamond is clear even in its rough form. But it is only when one of the world's finest diamantaires cuts and polishes it, using intricate skills handed down through the generations, that its full, astonishing beauty is revealed.

It then travels to the De Beers Group Institute of Diamonds in Antwerp, where it must undergo a 17-point evaluation. At the end of this rigorous process, only diamonds of the utmost quality are awarded Exceptional status.

The Exceptional Diamond journey

The story of every Exceptional Diamond is unique. Which is why each one is accompanied by its own bespoke journey book and replica of the diamond in its unpolished form. The book details the journey of the diamond from its formation deep below the Earth’s surface to its transformation into a modern masterpiece – a story billions of years in the making.
