We love star-studded award ceremonies and film festivals as we can take a look at the type of jewellery that is being worn.

Cannes Film Festival 2012, which started on May 15th, is in full swing giving us plenty of opportunity to see what our favourite celebrities are wearing.

A regular on the Best Dressed lists is actress Diane Kruger and she has not disappointed this year.

On the opening day of the ceremony, she wore a green Giambattista Valli couture gown complemented with a white gold ladies designer watch and matching earrings.

The ‘Troy’ actress took her ladies watch for another spin last night (May 17th) when she attended the Calvin Klein-sponsored Women in Film celebration.

This time around, she wore her watch to accompany a cleavage-enhancing red dress and white strappy sandals.

She was accompanied to the event by her partner Joshua Jackson, with whom she has been in a relationship for six years.

British actress Frieda Pinto, known for her role in ‘Slumdog Millionaire’, also wowed on the Cannes red carpet.

On the opening day, she rocked a Michael Angel pale pink dress with a beaded bodice, worn with Louis Vuitton silver platform sandals.

She also accessorised with jewellery, including a ring and white gold earrings.

For the opening night dinner, she chose a black Versace gown complete with a thigh-high split and sheer sleeves.

Fellow British actress Tilda Swinton has also been showing off her eccentric take on fashion at the Cannes Film Festival.

She showed older women how to look fashionable with her choice of outfit for a press conference about her new film ‘Moonrise Kingdom’.

Swinton wore a silk blouse, sky blue pencil skirt and heels complemented with a ring on each hand.

The film festival continues for the next seven days so keep your eye out for the stunning jewellery that is being worn by A-listers on the red carpet.
