Mila Kunis was the go-to when Gemfields needed the perfect “It Girl” to personify their empire.

Not only is she stunning, but she is subtle and relatable. Gemfields is the world’s largest distributor of ethically sourced rare colored gemstones. The company is committed to transparency, and Mila’s outspoken demeanor and confidence made the two a perfect match.

Most recently though, Gemfields is exhibiting it’s renowned and ethically responsible ruby line with Mila is its cover girl. Kunis is no rookie to the brand though; Gemfields took her on as their golden girl in 2012, and she has been coinciding in projects with the socially conscience gemstone producer since.

In honor of her first born with her new hubby (as of July 4th), Ashton Kutcher, Kunis teamed up with Gemfields to turn her baby bump into a charitable deed. She designed an emerald motherhood ring in which portions of the profits go to a maternity center in Zambia.

Kunis is a gem in the ruby campaign shot by Peter Lindbergh. Her grace and poise is effortless and her natural beauty is impossible to ignore. Kunis is honored to be in representation of a company of such economic and social proportions.
