Billie Eilish and her brother, Finneas, are taking their creative partnership beyond the music industry. The Grammy-winning siblings have joined forces for an unexpected business venture with luxury jewelry brand John Hardy. Their latest collaboration brings their personal styles into the world of jewelry.
The Grammy-winning siblings are exploring a new creative venture together
Eilish and Finneas have partnered with luxury jewelry brand John Hardy on their first co-designed collection. The line launched Wednesday, October 21, featuring two distinct collections. Prices range from $195 to $2,400, with designs inspired by their contrasting aesthetics.
The first collection, called “Wildflower,” draws inspiration from Eilish’s song of the same name. The track appeared on her 2024 album, Hit Me Hard and Soft. The assortment features delicate designs, including diamond-accented necklaces, stacking rings, floral earrings, and bracelets.
Meanwhile, the “Screwball” collection embraces a bolder, industrial-inspired aesthetic. Its designs feature chunky sterling silver chains, sculptural links, and distinctive hardware. The collection includes statement necklaces, matching bracelets, and an open ring.
Eilish explained that jewelry plays an important role in her personal expression. “Jewelry has always been an enormous part of how I express myself,” she said in a statement. She also described it as “such an important reflection of a certain time in your life.”
The new venture represents a deeper collaboration between the siblings and John Hardy. The brand previously appointed them as its first celebrity ambassadors in 2025. This time, they worked directly with design teams in New York and Bali.
Under creative chairman Reed Krakoff, the siblings helped develop the collection’s proportions, silhouettes, materials, and finishes. Their involvement extended beyond appearing in promotional campaigns, allowing them to translate their individual creative identities into wearable designs.
Sustainability also played an important role in the collaboration. Each piece is handcrafted using more than 99% reclaimed sterling silver. Select designs also incorporate lab-grown diamonds, reflecting the siblings’ longstanding environmental commitments.
The launch includes a campaign created with Trey Laird and filmed on grainy Super 8. The Billie Eilish and Finneas collection is now available through John Hardy’s website and select retailers.
