We have kicked off Day One of the Cannes Film Festival and it has been a treat to see the style stars work their magic. It’s time to pay the beautiful accessories some attention and shine the light on three actresses who impressed us, as they worked the red carpet.

Naomi Watts wearing Bulgari’s High Jewelry collection.

First on the list, is Naomi Watts with Bulgari. Her one-of-a kind statement necklace, Italian Extravaganza, stood out against her blonde hair and porcelain skin. The high jewelry necklace must have been heavy but she showed no signs of fatigue— what a pro. The final count on that dazzler? We spy 130 carats of amethysts, 35 carats of rubellites, 52.79 carats of aquamarines and 6.13 carats of diamonds. She topped it off with a pair of round brilliant cut diamonds in platinum from Bulgari’s high jewelry collection.

Julianne Moore wearing Chopard’s Green Carpet Collection.

Next up, is Oscar wnner Julianne Moore. She completed her outfit with a pair of emerald earrings and a ring from Chopard’s new Green Carpet Collection. The capsule collection will be launched officially May 14 so this serves as a teaser to what is to come. The pear-shaped emeralds — 10 and 11 carats each — are surrounded by marquise cut diamonds. The ring, in 18-carat white gold, features a 10.3-carat cushion-shaped emerald and marquise-cut diamonds. To learn more about the emeralds and Chopard’s collaboration with Gemfields, click here.

Jessica Chastain in Piaget’s High Jewelry collection.

The final stunner that caught our attention is Jessica Chastain. Her Piaget necklace from the brand’s high jewelry collection stood out against her brightly hued Armani Privé gown. The simple and elegant necklace was the only accessory she wore that night and we say it was an excellent choice.
