Sian Design is a Munich-based fine jewelry brand founded by Simon and Antonia, partners in both life and art, who explore the intersection of mathematics, architecture, and emotion.

Each design begins with an algorithm—a unique formula defining geometric and spatial relationships—allowing the creation of intricate 3D models that are then transformed into tangible forms.

This fusion of digital innovation and traditional goldsmithing results in pieces that feel both futuristic and timeless. Every jewel is crafted through additive manufacturing and finished by hand using the ancient lost wax casting technique, ensuring that no two pieces are ever identical.

Working primarily in 18kt gold, Simon and Antonia translate the logic of structure into sensual, wearable sculpture—bridging the precision of computation with the warmth of human touch.

Rooted in the rigor of design and the intimacy of craftsmanship, Sian Design embodies a new language of beauty — refined, rational, and quietly poetic.
