Not everyone can pull it off… but actress Mila Kunis goes make-up free in front of the camera as the face of Gemfields – the world’s leading supplier of colored gemstones. The brand’s 2014 campaign, Beauty By Nature, stars Kunis looking all natural shot by fashion photographer Peter Lindbergh.

The campaign marks the second time Kunis has collaborated with the company. Kunis traveled to the Gemfield mine in Zambia to ensure the stones were ethically and responsibly sourced.

“The visit to the Kagem emerald mine was fascinating and the trip itself was unforgettable,” Kunis told Vogue.
