Mila Kunis is done with Dior as she has been announced as the new face of Gemfields.

The Oz: the Great and Powerful star was snapped by Mario Sorrenti wearing one-of-a-kind emerald and ruby jewelry designed by the Gemfields’ partners, including The Gem Palace, Amrapali, Fabergé, Alexandra Mor, Dominic Jones, and Sutra. How fitting!

The photos will not only be feature in the pages of Vogue, Vanity Fair, and W but also a coffee table book on emeralds and a collaboration with 37 international designers in March.

Kunis took the time to learn more about the jewelry company before signing on, even spending four days touring Gemfields’ Zamabian mine, which produces 20 percent of the world’s emeralds. “It was incredibly important for me to know where everything comes from,” she told Women’s Wear Daily. “I want to learn from the people I surround myself with and the companies I work for, because when I don’t listen to that little gut [feeling], it doesn’t work out that well.”
