Birds of a Feather hitmaker Billie Eilish and her brother, music producer Finneas, have collaborated with John Hardy on the jewellery brand's new Lovestruck collection.

The label took to social media to share the news, posting 'In their debut season with the brand, the internationally acclaimed, multiple Academy and Grammy Award-winning siblings and collaborators step out in sustainably lab-grown diamonds from our new JH Lovestruck collection - a non-traditional diamond line designed for those who dare to break the mould'.
