About us

Mary's Copper is a UK jewellery brand launched by NK E-commerce, a Dutch company, and built around one idea: jewellery should be easy to wear every day, and the pieces you wear every day deserve to be made properly.

Our Mission

To give people jewellery they can rely on. Pieces that are exactly what we say they are, 99.9% pure copper, and still look right a year later. We would rather sell you one bracelet you never take off than five you wear once and forget.

Our Vision

We want jewellery to be something you choose once and enjoy for years, instead of something you replace every season because the plating wore off. Clean designs, solid weight and a material that gains character over time, not just for a single photograph.

What We Offer

Our jewellery covers bracelets, cuffs and bangles, rings and toe rings, earrings, necklaces and anklets, including a range of men's bracelets. Our copper essentials cover mugs, water bottles, straws and tongue scrapers.

  • 99.9% pure copper in every piece, never plated or coated, with open-backed cuffs and rings you can gently adjust to fit.
  • Free tracked shipping on every order, with no minimum spend.
  • Thirty days to return anything that is not right, and nothing to pay if an item arrives faulty.
  • A customer service team you can reach by email or phone, staffed by people who can actually look up your order.

How We Work

We select every piece ourselves and work with a small group of manufacturing partners who ship directly to you. Cutting out the middle layer is what keeps the prices where they are. It also means an order takes a little longer to arrive than it would from a shop down the road, so we publish our real processing and delivery times on the Shipping Policy page rather than promising a next-day delivery we cannot keep.

Who We Are

We are NK E-commerce, a Dutch company (company no. 42059404) based at Kernkade 2, 3542 CH Utrecht, The Netherlands. We launched Mary's Copper as a brand for the United Kingdom: we sell to customers in the UK and price everything in pounds sterling. Our company address is not a return address.
