De Beers to Close Lab-Grown Diamond Brand, Shift Back to Natural Diamonds

De Beers, a big diamond company, is shutting down its lab-made diamond brand, Lightbox.

This is because the lab-made diamonds became much cheaper, and the company wants to focus on the more expensive natural diamonds.

Some experts think this means the diamond market is changing, with natural diamonds becoming more important.

Others believe lab-made diamonds are still growing and are popular with consumers.

The closure shows how the diamond business is adapting to changes in what people want and how much they are willing to pay.
