Art Nouveau Style Moth/Butterfly Brooch

This is a large, ornate brooch featuring an intricate design reminiscent of a moth or butterfly, clearly influenced by the Art Nouveau aesthetic. The brooch measures approximately 6-8 cm in width based on visual estimation for a 'large' brooch. It is constructed from a non-precious metal, likely a base metal alloy with an antique gold-tone or bronze finish, exhibiting a deliberate aged patina that enhances its vintage appearance. The design is highly detailed, with delicate filigree-like openwork forming wings and a central body. The front of the brooch is embellished with numerous faceted rhinestones and cabochon-style stones in a variety of colors, including pale blue/green opalescent stones, clear or champagne-colored rhinestones, and occasional darker red or pink accents. A prominent, larger, oval-cut stone in a peach or rose color is centrally set, serving as a focal point. The stones are set in individual bezels or prongs, indicating some level of craftsmanship. The reverse side reveals the construction of the metalwork, which appears cast, showing textures and crevices consistent with this manufacturing method. A simple pin mechanism, consisting of a straight pin with a safety clasp, is securely affixed to the back. There are no visible maker's marks or signatures in the provided images. The overall condition is described as 'very good,' suggesting minimal wear and tear, with all stones present and the pin mechanism fully functional. The piece's substantial size and decorative elements make it a striking accessory, likely intended as a statement piece. The detailed composition and varied stone palette speak to the decorative jewelry trends of the early to mid-20th century, or more contemporary pieces crafted in an antique revival style.
