Chaban Technical Design Plan for Earrings and Brooch

This item is a detailed technical drawing and jewelry design plan on heavy-gauge paper or cardstock, dated December 2025 by the designer Chaban. The document features orthographic and perspective renderings of fine jewelry components, specifically an earring at a 2:1 scale and a brooch at a 1:1 scale. The drawings indicate complex structural elements including a fan-like or radial pavé setting and curved armatures, likely intended for fabrication in precious metals like white gold or platinum with diamond accents. The layout includes specific measurements, notations in cursive handwriting, and a formal production stamp in the lower-left corner titled 'Plan de Fabrication.' The physical condition of the sheet appears excellent, with sharp edges and no visible creasing or staining, suggesting it is a master archival copy. The draftsmanship shows high-level professional quality consistent with luxury haute joaillerie design, featuring precise line work and shading to denote metallic reflections. The document serves as both a creative blueprint and a technical specification for gemstone setting and metal casting.
