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.

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.

Invisible to the naked eye, the inscription on each Exceptional Diamond carries the 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.

Of all the polished diamonds resulting from the rough diamonds mined by the De Beers group of companies, only one in a million can become a polished Exceptional diamond.

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 uncut and 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.
