De Beers Announces It Will Close Its Lab-Grown Diamond Brand Lightbox
- De Beers Group said on 8 May 2025 it intends to close Lightbox, the lab-grown diamond jewellery brand it launched in 2018 with linear pricing of $800 per carat[1]
- Lab-grown diamond prices in the jewellery sector have fallen 90% at wholesale since Lightbox launched, diverging sharply from natural-diamond prices[1][2]
- CEO Al Cook said the closure reflects De Beers becoming "a standalone company" and reinforces its focus on natural diamonds against low-cost lab-grown competition, much of it from China[1]
- Element Six, De Beers' synthetic-diamond arm that once supplied Lightbox, will refocus solely on industrial applications such as semiconductors, and the Portland, Oregon factory built for Lightbox will be repurposed for that work[1][3]
