Jessica Chastain's Jewelry Steals The Show At Cannes 2014 (PHOTOS)

Cannes 2014 is coming to a close, so what better way to celebrate than with an eyeful of gorgeous jewelry?

"True Detective" star Jessica Chastain momentarily stole the spotlight from Sharon Stone at the annual amfAR charity gala on Thursday night thanks to her striking necklace.

The fiery redhead paired her custom black Givenchy Couture strapless gown with a dazzling diamond-encrusted Tesiro leaf necklace that we couldn't stop staring at.

With her locks styled into elegant waves, the "Zero Dark Thirty" actress looked effortlessly chic.

The 37-year-old has had more than a week to perfect her Cannes red carpet style: "The Help" star wowed in a vivid blue Atelier Versace gown last week and channeled an ethereal princess in a dreamy lavender Elie Saab gown at the "Foxcatcher" premiere.

One thing's for sure: Jess is a red carpet pro!
