The actress, who is nominated for outstanding performance by a female actor in a leading role for her performance as Megyn Kelly in Bombshell, admits she didn’t have time to hit the hair salon before the awards ceremony. But she decided to turn it into a major fashion moment.
With her hair parted in the center and pulled back into a sleek up-do, Theron’s dark roots were slightly visible, so her hairstylist Adir Abergel suggested she add some jewels to complete the style.
“I didn’t have time to do my roots. So my lovely friend Adir said, ‘Why don’t we throw a Tiffany necklace or bracelet in there,'” Theron tells PEOPLE on the SAG Awards red carpet.

Her hair wasn’t the only part of Theron’s look with a little bit of glitz. The actress, 44, hit the red carpet in a Givenchy Haute Couture sparkling silver hand-embroidered crop top with a belted black maxi skirt, teamed with platform sandals and a clutch (also by the label) and an over 3-carat Tiffany & Co. Victoria line diamond bracelet in her hair – worth $15,500.
In fact, she sparkled in $4 million worth of Tiffany & Co. diamonds, including stunning over 11 carat Tiffany diamond earrings, paired with exquisite Tiffany diamond bracelets and rings.

The SAG nominee opened up to PEOPLE about researching for her role as Kelly for the acclaimed film centered on the Fox News drama. “The good thing about playing someone who is that well-known is that there’s a lot of footage. There’s a lot to read about. There’s a lot for your research,” she says.
Theron adds: “The voice… I wasn’t even convinced we were going to get anywhere. But I have an amazing dialect coach, Karla Meyer. There should be a nomination for dialect coaches and she would win it this year! I still don’t know how she does it.”
Although Theron recently lost at the Golden Globes and Critics’ Choice Awards, she did earn an Academy Award nomination for Bombshell earlier this week. “It’s been a thrilling couple of weeks,” she said after the news was announced.
