American actress Eva Longoria in Damiani's diamond earrings
In Cannes on the French Riveria however, it has been balmy days and pleasant evenings suitable for walking down the red carpet in a special gown with bare arms ... to show off bracelets; upswept hair to show off earrings and low necklines to show off necklaces.
Cannes Film Festival is always a good show on the jewellery front with the European jewellery houses like Bulgari, Chopard, de Grisogono, Montblanc and Boucheron lending their jewels to the famous faces of models, actresses, celebrities, and personalities from the film world.
Diamonds of course were in good supply, emeralds made a noticeable appearance and some colourful vintage pieces were evident as well.
Take a look at some of the red carpet jewels....
