The Cannes Film Festival was hit by a second suspected jewellery heist when a diamond necklace worth 2 million euros (£1.6 million) vanished during a star-studded party, according to upmarket jeweller De Grisogono.
Fawaz Gruosi, the founder of the Swiss firm, said the necklace was part of the company's 20th anniversary collection paraded by 20 models at the glitzy event at the Hotel Du Cap-Eden-Roc in Antibes outside Cannes on Tuesday night.
Sharon Stone and Paris Hilton were among the guests.
Mr Gruosi said 80 bodyguards, local police, hotel security, and De Grisogono staff had been on duty but when a check was made at the end of the night the diamond necklace was missing.
"We don't know exactly what happened ... it was one of the most beautiful items we had," Gruosi told said
