Sian

Sian is a Munich-based fine jewelry brand founded by Simon and Antonia, partners in both life and art, dedicated to crafting pieces that fuse intricate mathematical structures with minimalist elegance. Each design begins with an algorithm, a unique formula that defines the logical and geometric relationships between every element, enabling rapid exploration of complex forms through advanced prototyping. This process allows for the creation of highly detailed, precisely controlled virtual 3D models that are translated directly into tangible forms. Drawing from backgrounds in computational design and architectural geometry, Simon and Antonia bridge digital innovation with traditional craftsmanship, transforming technical mastery into wearable art.

The production process combines additive manufacturing with classic goldsmithing to push the boundaries of jewelry design. Each piece is meticulously crafted layer by layer from wax, which serves as a foundation for the “lost wax casting” technique. After the wax form is encased in gypsum to create a mold, precious metals such as 18kt gold are poured in, and each mold is broken to release a one-of-a-kind piece. Every item is then hand-finished by skilled artisans, creating a lively, unique surface that reflects Sian's dedication to artistry and innovation. Inspired by nature, the brand’s designs merge simplicity with complex geometry, crafting timeless jewelry that could never be realized through traditional means alone.
