Sian Design
Fascinated by mathematical structures and minimalist design, Antonia Frey-Vorhammer and Simon Vorhammer combine digital and analogue methods to create their jewelry. Crafted from 750 gold and marketed under the Sian Design label, their collections are inspired by nature and combine simplicity with complex geometry. Basic shapes and smooth surfaces merge seamlessly into doubly curved surfaces and grid structures that cannot be achieved by traditional methods. Each piece is first assembled from wax components formed via 3D printing. This positive shape serves as the basis for a plaster cast into which molten precious metal is poured. Meticulous reworking by hand endows each piece with a lively surface. Since 2022, the cocktail ring Emi is part for the jewelry collection of the Museum of Applied Arts in Cologne (MAKK) and can be seen as an example of contemporary jewelry art in the exhibition Fascination Jewelry – 7000 Years of Jewelry Art at the MAKK until August 24, 2025.
