Antique 18 kt Gold Brooch with Onyx and Micromosaic – Bird Motif – Italy, ca. 1880–1920 Elegant antique brooch crafted in 18 kt yellow gold, featuring a finely executed micromosaic set on a polished black onyx panel. The central decoration depicts a charming bird perched on a floral branch, composed of numerous tiny colored glass tesserae, a technique traditionally associated with Italian (Roman) craftsmanship. The brooch is framed by a richly decorated gold border, adorned with a Greek key (meander) motif and delicate engraved floral details, reflecting the neoclassical taste popular during the late 19th to early 20th century. Micromosaic jewelry such as this was highly appreciated during the Grand Tour period, when travelers collected fine decorative pieces from Italy. The use of onyx combined with gold indicates a higher-quality example rather than a simple souvenir piece.
