GRESHAM, Ore. — The De Beers Group has announced plans to manufacture synthetic diamonds at a factory in Gresham, Ore.
The British diamond giant said in a news release Tuesday it will spend $94 million on the production facility over the next four years. Once fully operational, the plant will be able to annually produce 500,000 rough carats of lab-grown diamonds.
The diamonds will be marketed under the name Lightbox. They will retail from $200 for a quarter-carat stone to $800 for a one-carat stone — much less than traditional diamonds.
The plant will be in the Gresham Vista Business Park, and eventually employ about 60 workers.
