The finishing workshop gives each piece its final character. Through precise hand-finishing, surfaces are refined and the quality of the entire manufacturing process is revealed.
01 / How we work
The finishing workshop brings together specialist handcraft and controlled surface treatment. Across polishing, satin finishing, blasting, perlage, and decorative techniques, each operation refines the surfaces, preserves the intended geometry, and reveals the quality built throughout the manufacturing process.
Finishing supports the piece at every stage, from preparation to final refinement, with each gesture measured to protect lines, volumes, and balance.
Finishing accompanies each piece throughout production. Surfaces are prepared, refined, and corrected as the piece evolves, removing traces of previous operations and ensuring control even in the most difficult areas.
Most finishing operations are performed by hand and require absolute dexterity. Each gesture is precise and measured, preserving the lines, edges, and geometries that define the balance of the piece.
Polishing, satin finishing, sandblasting, micro-sandblasting, micro-bead blasting, perlage, and sunray finishing create distinct surface expressions. Each technique defines a specific interaction with light, from mirror polish to controlled matte textures.
A dedicated plating area applies rhodium and gold finishes through electrolysis. This process enhances surfaces, creates contrasts, protects selected areas, and introduces controlled decorative effects.
Masking enables selective finishing, allowing one area to be treated while preserving another. Varnish applied within engravings enhances contrast and definition, reinforcing the clarity of each detail.
