The natural diamond industry is facing an existential threat: lab-grown diamonds. They’re chemically and physically identical to natural stones, and they're just a fraction of the price. Eleanor Olcott, the FT’s China technology correspondent, travelled to the epicentre of lab-grown diamond production in the central Chinese province of Henan to see how they’re made. While the FT’s natural resources editor, Leslie Hook, explores what the sale of leading natural diamond producer, De Beers, could mean for the future of the sector.
