How could the Global Diamond Consortium's acquisition of De Beers affect Cartier?
Cartier may gain supply chain influence if Richemont joins the Global Diamond Consortium If Cartier's owner, Richemont, joins the Global Diamond Consortium (GDC), it could give the French jeweler greater influence over the natural diamond supply chain. The GDC is the preferred bidder for De Beers, which is being sold by Anglo American. Richemont is already noted as one of De Beers’ largest customers, giving it an important voice in the industry's future. While joining the GDC would offer strategic benefits, the broader market remains challenged by lab-grown gems, which now constitute 50 percent of total diamond volume.

Everything about Gareth Penny -
Cartier's owner, Richemont, is in advanced talks to join the GDC. This participation would bring major sellers of finished jewellery into the ownership of the rough diamond supplier. As a major customer of De Beers, Richemont's involvement in the new consortium could provide the jeweler with a greater voice in the future of the natural diamond industry and help secure high-quality stones.

Why it matters
For Cartier, the primary stake is maintaining a stable and high-quality supply of natural diamonds in a market increasingly threatened by lab-grown alternatives. Gaining a strategic foothold in the new De Beers ownership structure could allow the jeweler to hedge against the proliferation of synthetic stones and secure access to premium rough diamonds.
However, the wider industry is struggling with compressed polished diamond prices. The GDC's formation is part of a larger effort to stabilize consumer perception of natural stones, which is critical for luxury brands like Cartier. The success of this new structure depends on its ability to differentiate natural diamonds and reignite consumer desire.
