Bella Thorne is turning heads at the Cannes Film Festival.

The actress, 26, attended the movie premiere of Motel Destino on Wednesday, May 22, wearing a striking ruby necklace.

Thorne’s chain from Chopard consisted of ethical 18-carat white gold, a 123.18-carat pear-shaped rubellite and 65.24-carat diamonds.

The star completed her dazzling look with 18-carat white gold Haute Joaillerie Collection earrings set with 9.59-carat diamonds, and two diamond rings from the L’Heure du Diamant Collection.

Posing on the red carpet, Thorne looked elegant and sophisticated as she wore a full-length, off-the-shoulder black gown that featured a thick collar sleeve and a mini trail.

Donning a straight face to the cameras and keeping her arms to her side, the Shake It Up alum kept her hair equally stylish by sweeping it into a classic updo.

A lover of jewels, Thorne opened up to PEOPLE in December 2023 about her jewelry brand THORNE, which she debuted in 2022.

“My jewelry is just an additive of who I am. So I work out in it, I sleep in it and I shower in it. I just never take it off,” she told PEOPLE at the time, adding that her jewelry also allows her to cuddle with her fiancé Mark Emms.

Thorne explained that she made sure her THORNE’s holiday collection consisted of jewelry that didn’t scratch or dig into the skin, adding that film producer Emms was “100 percent” pleased about it.

She went on to say that the pair were “big cuddle bugs” and that Emms was there to test out the products. “He was throughout the whole testing process,” she said.

The couple confirmed their engagement in May 2023 after nine months of dating. Emms proposed at Thorne’s home in California with an emerald-cut diamond ring.
