Kerry Washington celebrated Earth Day in style.

The Emmy Award winner, 45, put on a sizzling display Friday, posing for an impromptu shoot in a green bikini and some gold jewelry from her brand Aurate. "Going green for #EarthDay! 💚," she wrote in the caption.

"Buy some sustainable jewelry and help save the 🌱🌎!!!" Washington added. "Today and tomorrow only, @auratenewyork is donating a % of proceeds to the Rainforest Alliance to help protect nature and improve the lives of farmers and forest communities."

She invested in the female-founded brand by Bouchra Ezzahraoui and Sophie Kahn in 2020, telling PEOPLE that she enjoys designing jewelry as it's "the part of fashion that holds the most emotional resonance."

"I like working in an element of fashion that feels more filled with our heart-centered connections with each other. And it's why it was so important to me that the collection had embodied themes that were really important to women. This is really a brand that's by women, for women," Washington said. "And so, I wanted to do something that really felt inspiring, uplifting and provocative."

Washington's sustainable jewelry collection also includes souvenirs from her storied career. She told PEOPLE last year that she saves a piece from each of her characters' wardrobes after the project wraps, and "every once in a while," she tries them on.

"I really use jewelry when I'm thinking about what's most important to a character. So for one character, I might wear a necklace with a cross on it," she said in November. "When I was doing American Son for Netflix, I was playing a mom and we custom-made a necklace with a 'J' for my son's name. For Olivia [Pope] from Scandal, I saved some of her earrings. I think about it a lot when I'm preparing a character."
