The Oscar-winning actress has teamed up with Chopard to create her own collection featuring ethically-sourced gemstones.

She says of her new role, "You design while thinking of the people who work on extracting the stones, so it's a totally different energy. Why should the creation of dreams and luxury turn into a nightmare for the people who are providing the raw material?"

Cotillard will unveil her designs, including a necklace and bracelet, during an appearance at the Cannes International Film Festival in France in May (15).
