The Most Spectacular Jewellery From Cannes 2017 

She's Bulgari's latest ambassador and kicked off her mega-glam visit to Cannes by wearing a sparkling 180-carat sapphire necklace with her pale pink, strapless Alexandre Vauthier dress.

This time a necklace and bracelet from Bulgari's classic Serpenti collection were Bella's jewels of choice.

Now this is a necklace. We'll be dreaming of EmRata's Bulgari bling for months. 

She didn't need much to top off her already-spectacular Vivienne Westwood gown, so a v.pretty Tiffany Soleste ring was just the right amount of sparkle for Elle.

RiRi rocked her Dior with a black nephrite cuff set - complete with a 31.95-carat emeralds - and diamond and emerald earrings from her new collection for Chopard.

Dripping in Chopard. How else would Rihanna rock a red carpet?

Nicole Kidman in custom Calvin Klein and Harry Winston jewellery was our favourite look of Cannes. Hands down. Add together her earrings, bracelet and two rings and you've got 70 carats worth of diamonds. Spectacular. 

For another red carpet appearance, Nicole accessorised her beaded, boho-inspired Armani Privé couture gown with a collection of vintage diamonds by Stephen Russell of New York.

I mean, these jewels aren't even available yet. Miss Chastain gave us sneak peak at Piaget's soon-to-be-revealed Sunlight Jewellery collection, by giving this ruby and diamond necklace its first spin on the red carpet. 

Naomi teamed her Verace with jewels from Bulgari's signature Serpentine collection.

Uma Thurman's pink sapphire and diamond oak leaf-shaped earrings from Chaumet’s La Nature de Chaumet collection are just so pretty. 

Which is the best accessory: Will Smith or those classic De Beers diamonds?
