In May 2018, De Beers introduced a new brand of jewellery called "Lightbox" made with synthetic diamonds. The synthetic stones start at $200 for a quarter carat to $800 for a full carat diamond. The new lab-grown diamonds retail for about one-tenth the cost of naturally occurring diamonds. The new brand began selling in September 2018 and the stones are produced in Gresham, Oregon, a $94 million facility using the region's cheap electricity, which opened in 2018 with the capacity for 500,000 rough carats of diamonds per year.
