Billie Eilish and Finneas have spent much of their careers making music together. Now, the Grammy-winning siblings are bringing their creative partnership into to the jewelry business.

The pair have teamed up with luxury jewelry house John Hardy on their first co-designed collection, launching Wednesday, Oct. 21, with two lines that reflect their “contrasting personal styles,” according to a press release. There’s “Wildflower,” a delicate, diamond-accented assortment inspired by Eilish’s hit song of the same name, and “Screwball,” a more industrial collection of chunky sterling silver chains and sculptural hardware. Prices range from $195 to $2,400.

“Jewelry has always been an enormous part of how I express myself,” Eilish said in a statement. “It’s such an important reflection of a certain time in your life.”

The collaboration marks a new chapter in the siblings’ relationship with John Hardy, which tapped them as its first celebrity ambassadors last year. This time, rather than simply fronting a campaign, Eilish and Finneas worked directly with the brand’s design teams in New York and Bali under creative chairman Reed Krakoff, developing everything from the pieces’ proportions and silhouettes to their materials and finishes.

In line with the siblings’ longstanding commitment to sustainability, each piece is handcrafted using more than 99% reclaimed sterling silver, with lab-grown diamonds incorporated into select designs.

The “Wildflower” line takes its name from the standout track on Eilish’s 2024 album “Hit Me Hard and Soft.” Among the pieces are a $695 sterling silver pendant necklace featuring a 0.1-carat lab-grown diamond, a $550 set of three stacking rings and $195 floral stud earrings. A diamond-accented station bracelet retails for $325, while a pair of dangling chain earrings costs $395.

“Screwball,” meanwhile centers on sculptural silver links, including necklaces priced at $1,150 and $2,400, matching bracelets ranging from $695 to $1,250 and a $295 open ring.

The new launch is accompanied by a campaign created with Trey Laird and filmed on grainy Super 8.

The Billie Eilish & Finneas collection is available now through John Hardy’s website and select retailers.
