Billie Eilish, Finneas Partner with John Hardy
The “Lovestruck” collection, designed with the Academy and Grammy award-winning siblings, is the brand’s first lab-grown diamond offering.

The alternative pop singer and the producer collaborated with Reed Krakoff, the brand’s creative chairman, to design the “JH Lovestruck” collection.
Lovestruck centers on four proprietary diamond cuts inspired by John Hardy’s pebble designs, which the brand said gives the gemstones a sculptural and modern feel ideal for everyday wear.
“There’s an honesty to these pieces,” said Finneas. “They feel intentional yet imperfect—diamonds with form and feeling, and without pretension.”
The stones, crafted into freeform organic shapes, were cut to maximize brilliance, rather than for value, the brand said.
“Traditional rules don’t allow for organically shaped diamonds. Lab-grown diamonds provide a creative freedom that makes it possible to imagine entirely new and proprietary cuts,” said Krakoff.
“Lovestruck breaks with tradition and defies the expectation that diamonds must come in standard shapes. With Lovestruck, we’re redefining how diamonds can be cut.”
Lovestruck was designed with an organic aesthetic that feels irreverent, modern, and effortless, said the brand, and it marks a new beginning for diamonds that are recut, remixed, and redefined in wearable jewelry meant to fit into real life.
The debut lab-grown diamond offering is the latest in a series of collections released this year in celebration of John Hardy’s 50th anniversary.
Across the collection’s 50 pieces, there are rings, bracelets, earrings, and necklaces as well as a pin, hand chain, and body chain crafted in 18-karat yellow gold or sterling silver.
While the diamond pieces are the focus of the collection, the “Heishi” styles also use onyx or orange spiny oyster shell beads.
The pieces are produced in facilities powered by renewable energy, according to John Hardy.
As part of the collaboration with Billie and Finneas, John Hardy has pledged support for philanthropic initiatives that inspired the musicians, who have been outspoken advocates for environmental sustainability.
This includes Support + Feed, a nonprofit committed to mitigating climate change and increasing food security by driving global demand, acceptance, and accessibility of plant-based food.
“Billie and Finneas’ commitment to sustainability, groundbreaking artistry, and creative talent make them a natural and authentic partner for the brand, and in particular for this collection,” said Krakoff.
Billie added, “I love that Lovestruck uses lab-grown diamonds, reclaimed precious metals, and each piece was crafted using renewable energy … What you eat, say, and wear matters, and jewelry is no different. It all impacts our planet.”
The creative partnership also includes a shoppable edit of John Hardy pieces that were worn by the musicians on tour as well as new designs based on Billie and Finneas’ aesthetic.
Billie’s curation can be seen on this page of the John Hardy website, while Finneas’ can be seen on this page.
The Lovestruck collection debuted on Sept. 29 and retails from $825 to $24,000.
It is available in-store at John Hardy locations and at select wholesale events, as well as on the brand’s website.
