A rare 888.88-carat natural black diamond, named Infinity, has made its public debut at the Dubai Diamond Conference 2026. The stone, classified as 'Fancy Black', was unveiled by Diamond Trading NV and transported to the event with Brink's security and cash management company. Diamond Trading NV, based in Antwerp, Belgium, specializes in sourcing, trading, and distributing rough diamonds globally.
The diamond, discovered in the Democratic Republic of the Congo, weighed 1,138 carats in its rough state when it was acquired by Andrew Coxon on behalf of De Beers in 1975. The Gemological Institute of America (GIA) recorded the rough crystal as the largest single-crystal natural diamond it had examined in 2013.
