Antique Art Nouveau Ruby & Rose-Cut Diamond 18K Yellow Gold Brooch Circa 1910

An exceptional original Art Nouveau brooch, circa 1910, beautifully executed in 18 karat yellow gold with the wonderfully organic, sculptural character that defines the period. The circular openwork composition is formed by richly textured leaves and sinuous curling vines, arranged with an effortless asymmetry and retaining a gorgeous, untouched period patina. Four natural rubies provide vivid points of crimson color throughout the design, while the center is accented by a charming natural antique rose-cut diamond, bezel set in the original mounting. Particularly appealing is the brooch’s remarkably honest state of preservation—the texturing remains crisp, the patina has not been polished away, and the original pin mechanism remains intact and functions properly. At just 1 inch in diameter, it has the refinement and versatility to be worn on a lapel, jacket, blouse, scarf, or evening piece without feeling overly formal. A sophisticated jewel with genuine age, character, and individuality—equally compelling for the collector of important period jewelry or simply for someone who appreciates owning something that cannot be replicated by modern production.
