Vintage Guilloché Enamel Sterling Silver Oval Brooch

This is an exquisite oval brooch measuring 2 inches in width and weighing 12.5 grams, crafted from sterling silver. The piece features a sophisticated guilloché enamel technique, characterized by a machine-turned engine-patterned silver substrate beneath translucent and hand-painted enamel. The design showcases a central off-white or light cream panel with a 'sunray' or 'basketweave' engine-turned texture, decorated with hand-painted pink rose clusters, green foliage, and dainty yellow bows. The central medallion is framed by a rich plum or amethyst-purple translucent enamel border that reveals a delicate wavy engine-turned pattern underneath. This border is further accented with a miniature 'painted-on' decorative trim of alternating green and gold-toned dots and fleur-de-lis motifs. The craftsmanship suggests an early to mid-20th-century origin, likely European (possibly Norwegian or Austrian), where such enamel work reached its peak. The condition appears excellent with the enamel remaining vibrant and lustrous; there are no visible 'fleabites,' cracks, or large chips to the glass-like surface. The sterling silver rim shows a light, natural patina consistent with age. Such pieces are highly collectible for their intricate combination of mechanical engraving and fine-art miniature painting.
