An exceptional signed Muller Frères Luneville Art Nouveau chandelier featuring a masterfully hand-forged wrought-iron frame adorned with naturalistic vine and leaf motifs. The fixture supports four elegantly curved arms and a central bowl, each fitted with signed pâte-de-verre glass shades. The glass displays the characteristic Muller Frères marbled palette—swirling tones of pink, cream, lavender, and deep cobalt—creating a luminous, atmospheric effect when lit. The wrought-iron structure is finely detailed, showcasing the craftsmanship typical of early 20th-century French decorative arts. Signatures: Each shade and center bowl is acid-etched “Muller Frères Luneville”, confirming authenticity. A superb collector-grade example of Muller Frères’ collaboration with period ironwork ateliers, perfect for refined interiors or serious Art Nouveau collections.
