John Hardy has launched its first jewellery collections designed by Billie Eilish and Finneas, a year after the siblings became the brand's faces, and this time they have gone from wearing the pieces to drawing them. The launch is split into two lines that reflect the pair's contrasting personal styles, as Wildflower takes its name and mood from one of Eilish's best-known songs while Screwball leans into the heavier, more industrial silver that Eilish favours when she is on tour. Together, they span $195 to $2,400, placing the collaboration well below the diamond-heavy pieces the siblings fronted last year and opening it up to a much younger audience.

The launch has turned what would have normally been a typical celebrity ambassadorship into something closer to a design partnership, as the siblings have spent the past year working with John Hardy's design teams in New York and Bali, helping to shape the proportions, silhouettes, materials, and finishes under creative chairman Reed Krakoff. The collections also continue the sustainability story that brought the three parties together, since every piece is handcrafted from more than 99% reclaimed sterling silver and select designs are set with lab-grown diamonds.

John Hardy's Wildflower and Screwball collections range from $195 floral studs to a $2,400 silver link necklace

Wildflower is the softer and more romantic of the two collections, named after the Grammy-winning song from Hit Me Hard and Soft that Eilish performed throughout her world tour, which wrapped in November 2025. The 2024 album behind that song peaked at No. 2 on the Billboard 200 and also produced the Hot 100 hit "Birds of a Feather", which gives the collection a ready-made audience among listeners who have followed the record since its release. The line includes $195 sterling silver stud earrings with carved petals for a three-dimensional look, a $695 pendant necklace with a 15.7mm pendant set with 0.1 carats of lab-grown diamonds on an adjustable rolo chain, and a $550 set of three stacking rings in which each band carries a different sculpted flower.

Screwball is the edgier counterpart, with chunky chain necklaces, sculptural bracelets and piercing-inspired hardware that give it an industrial feel, and its necklaces are priced at $1,150 and $2,400 while matching bracelets run from $695 to $1,250. The most accessible piece in the line is a $295 open ring with a 5.5mm band, and the two collections are designed to be worn together, so a floral Wildflower stack can sit alongside a heavy Screwball chain. Eilish explained the split in a statement, saying "Jewelry has always been an enormous part of how I express myself" and adding "It's such an important reflection of a certain time in your life."

She also described how the two collections map onto her own habits, as she said "In my current day to day, I wear daintier jewelry" and "On tour, I love a chunkier, thicker piece," before concluding "I love that we were able to work with both styles." The campaign was created with Trey Laird and filmed on Super 8, giving the imagery a grainy, home-movie quality that suits a brother-sister partnership, and the pieces are on sale at JohnHardy.com, in John Hardy stores, and through select retailers.

John Hardy's Billie Eilish and Finneas collaboration follows their 2025 Lovestruck lab-grown diamond campaign

The partnership began in September 2025, when John Hardy named Billie Eilish and Finneas the faces of JH Lovestruck, its first lab-grown diamond collection, a 50 piece range built around four proprietary freeform cuts inspired by the brand's pebble designs and priced from $825 to $24,000. That launch was part of a series of releases celebrating John Hardy's 50th anniversary, and Reed Krakoff explained that "Lab-grown diamonds provide a creative freedom that makes it possible to imagine entirely new and proprietary cuts," while calling the siblings "a natural and authentic partner for the brand." Finneas described the Lovestruck pieces as having "an honesty" to them, and Eilish tied the collection to her environmental values when she said "What you eat, say, and wear matters, and jewelry is no different," adding that "It all impacts our planet."

Sustainability is the thread that makes the siblings a credible fit for a jewellery house, because both are outspoken environmental advocates and John Hardy pledged in 2025 to support causes that matter to them, including Support + Feed, the plant based food and climate nonprofit founded by their mother Maggie Baird.
