Marcos & María Barcelona is a Barcelona-based brand creating handmade copper jewelry, with the site stating that it has spent 10 years crafting its pieces. Its collection uses copper described as 99.9% pure, worked piece by piece in the brand’s workshop. Products include bracelets, earrings, rings, anklets and necklaces, alongside copper accessories such as a pure copper water bottle. The range includes designs for women and men, with named styles including Bough, Raíz, Wick, Marsh and Grit.

The brand presents its pieces as suitable for everyday wear and highlights their water resistance. Customer testimonials describe the jewelry’s warm, rosy copper tone and mention wearing it during daily activities, though these are individual experiences rather than product guarantees. Marcos & María offers free standard shipping on orders, 30-day returns and a stated craftsmanship guarantee. Customers can contact the brand for questions or advice by email, and the site lists weekday and weekend support hours. Its online store also provides order tracking and information about copper care, payment, delivery, returns and privacy.
