Billie Eilish and Finneas have made plenty of hits together, but their latest collaboration is something you can actually wear.
The Grammy-winning siblings have teamed up with John Hardy for their first co-designed jewelry collection, available as of Wednesday, Oct. 21, at JohnHardy.com, John Hardy stores and select retailers. The collection features rings, necklaces, bracelets and earrings that reflect their very different approaches to personal style.
The lineup is split into two distinct styles. Wildflower, named after Eilish’s Grammy-winning song from Hit Me Hard and Soft, takes a softer approach with sterling silver flowers, delicate pendants and lab-grown diamonds. There’s even a triple ring stack that brings three floral designs together, plus threader earrings that can be worn through multiple piercings.
Screwball, meanwhile, is where things get a little edgier. Chunky chain necklaces, sculptural bracelets and piercing-inspired hardware bring an industrial feel to the collection, offering a contrast to Wildflower’s more delicate designs.
And this wasn’t a case of simply putting two famous names on a jewelry collection. The siblings spent the past year working closely with John Hardy’s New York and Bali design teams, helping develop the pieces from initial concepts to finished designs. Sustainability also played a role, with reclaimed metals and lab-grown diamonds incorporated into the collection.
“Jewelry has always been an enormous part of how I express myself,” Eilish said in a statement. “In my current day to day, I wear daintier jewelry. On tour, I love a chunkier, thicker piece. I love that we were able to work with both styles.”

The launch also gives “Wildflower” another moment in the spotlight. The track appears on Eilish’s Hit Me Hard and Soft, which peaked at No. 2 on the Billboard 200 and also produced the Billboard Hot 100 hit “Birds of a Feather.” Eilish performed “Wildflower” throughout her Hit Me Hard and Soft world tour, which wrapped in November 2025.
