Big Metal London is a London-based jewellery brand with a long heritage and a strong commitment to sustainability. Founded by James McGrath, the brand began over 30 years ago following his time working with artisan communities in Papua New Guinea, where he first discovered a passion for jewellery making.

After returning to London, James began creating jewellery in a small workshop before establishing a successful stall at Portobello Market. His work later gained international attention when Jean‑Paul Gaultier commissioned him to design jewellery for the film The Fifth Element.

Today, Big Metal London designs its collections in-house in London, combining contemporary fashion with responsible production. The brand prioritises recycled materials, including upcycled resin made from discarded sunglasses frames, recycled brass, and recycled castings for its silver and gold-plated pieces.

At the heart of Big Metal London is the belief that jewellery should be not only stylish and expressive, but also created with care for both people and the planet.
