Krösus Design

Seraina Sonderegger's atelier sits on Rindermarkt in Zurich's medieval old town, where she hand-makes every engagement ring individually. Working in platinum, Fairtrade gold, and silver, she creates pieces that reflect personal stories and preferences rather than mass production.

Since 1991, the atelier has served couples seeking rings as unique as their relationships. A visit to Rindermarkt gives you direct access to the goldsmith and the chance to collaborate on a truly custom design.
