ADFK Jewellery is the online studio of goldsmith Alexandra da Fonseca-Klein, offering distinctive jewellery crafted with precious metals and gemstones. The collection includes rings, earrings, necklaces, pendants and charms, bracelets and bangles, brooches, lapel pins and cufflinks. Customers can explore themed designs such as the Nature Collection, Bonbonring and pieces featuring citrine, topaz or pink sapphire.

Alongside ready-to-wear jewellery, Alexandra offers bespoke design and creation, helping customers develop personal pieces with details such as engraving and adjustments to ring size. Customer accounts describe a collaborative process, with photographs and updates shared during custom projects, as well as personal advice to help choose the right fit. The studio also provides workshops and other jewellery-related services.

ADFK presents its work through an online shop, where customers can browse collections, manage orders and find information about delivery and returns. The brand’s approach combines individual service with carefully made designs, creating jewellery for gifts, special occasions or everyday enjoyment.
