SIAN was founded in 2018 by architects and creative partners Antonia Frey-Vorhammer and Simon Vorhammer. Based in Munich, their work is shaped by architectural thinking and a shared sensitivity to structure, geometry and material. Antonia and Simon studied architecture together and have lived and worked in Copenhagen, Madrid, London and Sydney, developing a deep understanding of spatial relationships, material behaviour and design across scales. This experience continues to shape SIAN, where sensitivity for form and proportion meets a long-standing engagement with computational design, geometry and digital fabrication.

Jewellery emerged as a continuation of architecture on a more intimate scale. Structure, balance and logic remain present, translated into objects that engage the body through proximity, movement and proportion.

Nature is a constant point of reference, not as imagery, but as an underlying system. Organic growth patterns, natural geometries and the quiet intelligence found across scales inform a design language in which clarity and complexity coexist. Through SIAN, Antonia and Simon create jewellery as carefully considered objects with internal coherence. Guided by curiosity rather than trends, their work is designed to unfold over time and accompany the wearer with a quiet presence.

Each piece reflects an ongoing exploration: restrained yet expressive, precise yet intuitive, rooted in a thoughtful dialogue between concept, material and form.
