De Beers Group has announced its intention to close its lab-grown diamond (“LGD”) jewellery brand, Lightbox, reinforcing De Beers Group’s commitment to natural diamonds in the jewellery sector. As part of the closure process, De Beers Group is discussing the sale of certain assets, including inventory, with potential buyers.

Lightbox, which was established in 2018, has highlighted that LGDs are a distinct product from natural diamonds, with different attributes and different value. The business was launched with transparent linear pricing of $800 per carat. Since then, LGD prices in the jewellery sector have fallen 90% at wholesale, tracking closer to a cost-plus model as they have diverged from natural diamond prices. Reflecting this sharp price decline, De Beers Group intends to discontinue the Lightbox business. The evolution of LGD values in the jewellery sector underpins De Beers Group’s core belief in rare, high-value, natural diamond jewellery as a separate category from low-cost, mass-produced LGD jewellery.

The proposed closure of the Lightbox business reflects a key executional milestone in De Beers Group’s Origins Strategy, as set out in May 2024, to focus on high-return activities and streamline the business. The closure will enable De Beers Group to reallocate investment to initiatives focused on reinvigorating desire for natural diamonds through category marketing.

De Beers Group will work closely with employees, retail partners, suppliers, and other stakeholders to ensure a smooth process over the coming months. Customers will continue to receive support for existing purchases, including warranties and after-sales services, during the closure process.
