At the Cannes Film Festival, the diamonds shine as bright as the stars themselves.
Given Chopard’s been the event’s longtime official jewelry partner for decades, many of this year’s best gems hailed from the Swiss house — like Demi Moore’s five-tiered, 226.34-carat marquise-cut necklace, Adriana Lima’s 129-carat emerald collar and Ruth Negga’s fiery opal choker.
Other stars selected incredible baubles from Boucheron; Colman Domingo opted for a statement-making octopus ear cuff, Daisy Edgar-Jones styled her tie-inspired necklace backwards and Salma Hayek slipped on a diamond ring that easily occupied half her finger.
In between it all, we also spotted standout pieces from Tiffany & Co., Chaumet, Pomellato and more. Keep scrolling for all the best jewelry moments from the Cannes red carpet.
