Jewelry has long been a signature aspect of Billie Eilish’s style, whether she’s layering oversized silver pieces onstage or opting for something more delicate in her everyday life. Now, she’s taking that relationship one step further. Alongside her brother and longtime creative partner Finneas, Eilish is officially stepping into her jewelry design era with a new collection for John Hardy.

The “Billie Eilish & Finneas” Collection marks the siblings’ first time co-designing jewelry with John Hardy after being named creative partners last year. Developed over the course of a year alongside the brand’s New York- and Bali-based design teams, the collection showcases the pair’s evolution beyond the traditional ambassador role as they work with the house from initial concept through creation.
