Billie Eilish and FINNEAS launch new jewellery collections with John Hardy

Billie Eilish and her brother, FINNEAS, are expanding their creative partnership beyond music with two new jewellery collections designed in collaboration with luxury brand John Hardy, combining their personal styles with a shared commitment to sustainability.

Launched on October 21, the collections, named Wildflower and Screwball, were developed alongside John Hardy creative chairman Reed Krakoff. The collaboration builds on the siblings’ existing relationship with the brand, which began when they became its first celebrity ambassadors around a year ago. The new lines give Eilish and FINNEAS a more direct role in designing jewellery that reflects their individual aesthetics. 

The Wildflower collection takes inspiration from Eilish’s 2024 song of the same name, featuring delicate floral motifs across rings, earrings, bracelets and pendant necklaces. Crafted from sterling silver and lab-grown diamonds, the designs reflect the softer, more romantic side of the singer’s style.

In contrast, Screwball embraces a bolder, more industrial aesthetic, with minimalist designs intended to complement streetwear and layered jewellery looks. The two collections are designed to work together, bringing contrasting elements of softness and strength into a single wardrobe. 

Eilish said jewellery has long been an important part of how she expresses herself, describing it as a reflection of different periods in her life. She explained that her everyday style tends towards more delicate pieces, while she prefers chunkier jewellery when performing on tour.

“I love that we were able to work with both styles,” the singer said. 

FINNEAS also spoke about how his taste has evolved alongside his sister’s, explaining that they have become more minimalist as they have grown older. He said he increasingly appreciates simple silhouettes and understated designs.

The collection reflects the siblings’ ability to translate their creative instincts into a product beyond their usual work in music, where they have collaborated on songwriting and production for much of Eilish’s career. 

Sustainability is another central element of the partnership. The pieces are made using more than 99% reclaimed sterling silver alongside lab-grown diamonds, reflecting both the siblings’ environmental advocacy and John Hardy’s emphasis on responsible materials. 

The collections are priced between $195 and $2,400, making them more accessible than some of the brand’s higher-priced jewellery offerings. They are available through John Hardy’s online store and selected retailers, including Nordstrom. 

For John Hardy, the launch represents a significant expansion of its celebrity collaborations. Company president Matt Tepper described Eilish and FINNEAS as a strong fit for the brand because of their outspoken support for sustainability, a principle rooted in the company's founding philosophy.

The campaign accompanying the launch features the siblings in imagery shot on Super 8 film, reinforcing the collections’ blend of personal expression, artistry and craftsmanship. Both artists are also expected to promote the jewellery through their social media platforms. 

The new collections further extend Eilish and FINNEAS’s influence beyond the music industry, demonstrating how their shared creative identity can translate into fashion and design while maintaining a focus on sustainability.
