Billie Eilish and Finneas’s Latest Collaboration? Designing Jewelry

When brother-sister duo Billie Eilish and Finneas aren’t busy recording albums or performing live shows together, you can often find them making music even on their downtime—something they’ve been doing this fall, in a big way. “We’re in serious album mode right now,” Eilish said over a Zoom call last week. “We’ve been making a lot of music, and just hanging out with each other and our dogs.” (Which means, yes, there may be new music on the way).

This week, however, the pair are stepping outside of music, their core practice, to reveal a brand new creative project: a new collection of jewelry—including earrings, necklaces, bracelets, and rings—that they co-designed, releasing today, made in partnership with the jewelry label John Hardy. Even better, they’re sustainably-minded, all made of repurposed materials and lab-grown diamonds.

Eilish and Finneas first began working with John Hardy last year, as both faces and creative collaborators for the JH Lovestruck collection—but they felt this year was the right moment to step up their involvement by creating striking designs of their own. “There was a thought that, down the road, we’d do a collection, but there was no pressure for it,” says Eilish.

They worked with the label’s creative chairman, Reed Krakoff, to bring their visions to life. “Billie and Finneas each have their own incredibly strong sense of personal style,” says Krakoff of working with the two stars. “Both were willing to go against type: Billie is known for her oversized, edgy looks, but she was drawn to delicate flowers. Finneas seems more understated and laid-back, but he’s very confident and considered in his taste.”

The final result—titled the Billie Eilish and Finneas Collection, ranging from $195 to $2,400—is divided into two sub-collections. The first is titled Wildflower—a play on Eilish’s hit song—and revolves around daintier floral motifs meant for everyday wear. So intricate pendant necklaces, bracelets, earrings, and rings all feature intricate flowers carved out of reclaimed sterling silver, some punctuated with sparkling lab-grown diamonds.

“The Wildflower-inspired collection is what we would wear day to day,” says Eilish. Finneas adds, “I love the idea of somebody wanting the ring because they think it’s a beautiful ring—it’s not merchandise, per se. We wanted to make objects that are just appealing on their own.”

The Screwball line, meanwhile, focuses on more of a hard versus soft duality. Think sculptural chain links and spherical hardware that make more of a statement, all designed to be layered and mixed. Many of these pieces evolved around favorite pieces that Eilish and Finneas have tested over the past year. “I was on tour during the first several months of working on this, so I would have John Hardy send certain pieces that I could wear on stage, to see what would feel good,” says Eilish. “I wanted something that felt like it had a presence, but wasn’t hurting my neck while I was jumping around, or getting stuck on stuff.”

You didn’t even know it, but Finneas and Eilish were sneakily wearing the collection for many of their recent performances, and it was taking this more hands-on approach that really helped cultivate the assortment, says the duo. “We liked seeing how [the pieces] actually felt in our fingers—holding bracelets and necklaces in our hands,” says Finneas. “It all feels really wonderful: It’s not too heavy, but not too light.”

Eilish and Finneas wanted to create pieces that better reflected their personal style as it is today. Finneas, for one, favors a simpler wardrobe these days, so he wanted jewelry that popped and made a statement. “I have gotten more and more minimalistic in my taste of clothing and jewelry, and the role of jewelry becomes even more obvious if you’re wearing a very low-profile outfit,” he says.

Eilish, meanwhile, says she has pared back her signature edgy look recently, so she wanted to emphasize daintier pieces that could make a subtle impact in her day-to-day wardrobe. “When I was a teenager, I wore 10 rings every single day—I would wear so much jewelry,” Eilish says. “Now, I rarely wear jewelry in my day-to-day life.”

Most important was the environmentally-friendly approach. Both Eilish and Finneas say they knew from the start that whatever they created would have to be sustainably-minded. “Sustainability is such an important part of our lives, and [John Hardy’s] beliefs really aligned with what we prioritize and focus on,” says Eilish, who has uplifted various environmental and social causes during her own tours.

In using reclaimed silver and gold, they were surprised at just how easy it was to implement eco-friendly approaches into the manufacturing process. “We’ve been taught to accept that some necessary evils are going on in manufacturing, and I don’t agree with that,” says Finneas. For Eilish, learning about the pros of lab-grown diamonds versus traditional sourcing was eye-opening. “They’re molecularly identical to a tee—yet one is hard on the environment and people, and one is made in a lab,” says Eilish. “It's also unbelievably less expensive. I still hear people say, ‘Ew, lab-grown,’ and it’s like, ‘You would never know the difference!’”

Consider their debut jewelry collection, then, proof that you can wear mindful accessories—and do it in style. The brother-sister duo hopes for the line to resonate with all kinds of people—including both fans and non-fans alike. “I love the idea of people with such different personal styles to Billie or me wearing these same bracelets or rings, and feeling just as comfortable and confident in it,” says Finneas. “Billie has made a career out of wearing things that almost nobody else could pull off—there was a period when she cut up an IKEA bag and wore it—and you may not wear a repurposed IKEA bag as an outfit, but these rings can look great on you.”

So, with this experience, have Finneas and Eilish caught the design bug? Should we be expecting more projects—perhaps even clothing—coming down the line? Consider it a strong maybe—however, they say it’s just jewelry for now. “We’re definitely working on more things with John Hardy, potentially,” says Eilish. “I’m not really a planner: I like to move through life ready for whatever the hell is about to happen!”
