John Hardy Launches Jewelry Collection with Billie Eilish and Finneas

John Hardy has released a new jewelry collection designed in collaboration with Billie Eilish and Finneas, available from October 21 through the brand’s boutiques, website, and select retailers including Nordstrom. The Billie Eilish & Finneas Collection brings together the siblings’ distinct personal styles, with prices ranging from $195 to $2,400.

The collaboration marks the pair’s first foray into jewelry design after previously serving as ambassadors for John Hardy’s JH Lovestruck line. This time, Eilish and Finneas worked closely with the brand’s creative chairman, Reed Krakoff, and the design teams in New York and Bali. Their involvement extended to every stage of development, from conceptual sketches to testing prototypes on tour and during daily life.

The collection is divided into two lines. Wildflower, named after Eilish’s Grammy-winning 2024 song, centers on delicate floral motifs. Pieces include pendant necklaces, rings, bracelets, and earrings, all crafted from reclaimed sterling silver and set with lab-grown diamonds. Eilish described the line as reflecting her current preference for subtler jewelry: “In my current day-to-day, I wear daintier jewelry,” she said. That added that jewelry “has always been an enormous part of how I express myself.”

Screwball, the second line, introduces a harder edge with sculptural chain links and industrial-inspired hardware. The designs play with contrasts, hard and soft, bold and understated, and are intended for layering and mixing. Many of these pieces were refined after Eilish wore them on stage to test their comfort and presence during performances. Finneas said he wanted the objects to be appealing on their own, not just as merchandise, and liked the idea that people with different personal styles could feel comfortable and confident wearing the same pieces.

Sustainability was a priority for both Eilish and Finneas, who said from the start that any collection they created would need to be environmentally responsible. The siblings were surprised at how straightforward it was to use reclaimed silver and gold in the manufacturing process, and Eilish found learning about the advantages of lab-grown diamonds over traditional sourcing to be eye-opening. According to John Hardy, the collection uses more than 99% reclaimed sterling silver and lab-grown diamonds, and is produced in facilities powered entirely by renewable energy.

Krakoff, John Hardy’s creative chairman, said that both Eilish and Finneas brought their own strong sense of style to the project and were willing to explore ideas outside their usual looks. He described Eilish as being drawn to delicate flowers despite her reputation for oversized, edgy fashion, and noted that Finneas, though understated, was confident and thoughtful in his taste. The siblings’ approach resulted in a collection that feels personal to them while remaining true to John Hardy’s design language.

Eilish and Finneas first began working with John Hardy last year as creative collaborators and faces of the JH Lovestruck collection, but this new project gave them the opportunity to create their own designs. Eilish said she rarely wears jewelry in her daily life now, a shift from her teenage years when she wore multiple rings every day, and wanted to create pieces that would make a subtle impact. Finneas, whose style has become more minimal, wanted jewelry that would stand out against a simple wardrobe.

The siblings tested many of the pieces themselves, with Eilish wearing prototypes on stage to ensure they were comfortable and practical for performance. They said that holding the finished pieces in their hands and seeing how they felt was an important part of the process. The collection is intended to appeal to a wide range of people, regardless of whether they’re fans of Eilish and Finneas’s music.

The collection is available now through John Hardy’s website, boutiques, and at select retailers. The magazine has also looked at David Yurman’s recent men’s jewelry collaboration.
