Art Deco Green Stone and Sterling Silver Mask Brooch/Pendant

This exquisite piece is a striking Art Deco-style brooch or pendant, featuring a carved green stone face or mask set within an elaborate sterling silver frame. The central element is a deeply carved, possibly jadeite or chrysoprase, stone exhibiting a rich, dark emerald green hue with visible veining and natural inclusions, suggesting it is a genuine gemstone rather than glass. The carving depicts a stylized face, possibly of a deity or mythological figure, with prominent forehead ridges, defined eyebrows, and a somewhat stoic or serene expression. The carving style is rather abstract, emphasizing forms and lines over realistic detail. The surrounding metalwork is sterling silver, characterized by its darkened, oxidized patina which provides a stark contrast to the polished raised areas, enhancing the ornate, flowing scroll motifs that frame the central stone. These scrolls are symmetrical and extend outwards from the central mask, hinting at a winged or floral design. The construction appears solid and well-made, with the stone securely bezel-set within the silver. There are no immediately visible marks or signatures, though further inspection of the reverse would be necessary to identify any maker's marks or hallmarks for silver content. The visible condition suggests some surface wear consistent with age and use, particularly the varied patina on the silver, which appears deliberate in some areas and possibly naturally aged in others. No major damage like chips or cracks on the stone or significant dents on the silver are evident from the provided image. The overall aesthetic points to an early to mid-20th century Art Deco or possibly a Mexican modernist influence, given the jade-like stone and silver craftsmanship. This piece exemplifies quality craftsmanship through its detailed carving and intricate metalwork.
