Stained-Glass Window Panel – Art Nouveau / Jugendstil Geometry In Excellent Condition – No Reserve Striking early 20th-century stained glass panel featuring a refined geometric composition, executed in traditional leaded glass technique. The design is centered around a diamond-shaped motif with a deep red core, framed by emerald green and golden yellow glass, accented with vertical turquoise elements. The surrounding field is composed of softly textured, pale yellow glass, bordered by warm amber tones, creating a balanced and visually powerful composition. This panel strongly reflects the transition from late Jugendstil to early Art Deco, a period characterized by a move toward abstraction, symmetry, and architectural clarity. Such panels were commonly used in townhouses and apartments as transom windows or interior light panels, allowing natural light to enter while maintaining privacy and decorative impact.

These panels were often custom-commissioned for the upper class houses in Amsterdam, Antwerp, and Brussels, reflecting both artistic taste and prosperity. The textured glass in this piece is particularly characteristic of the period, offering both privacy and decorative depth. Provenance Private collection, Netherlands.
