Vintage Taxco Mexican Sterling Silver and Carved Onyx Mask Cuff Bracelet

This is a vintage Mexican sterling silver cuff bracelet featuring a large, central hand-carved black onyx stone, likely originating from Taxco, Guerrero. The focal point is a stylized 'Warrior Mask' or 'Teco Mask' carved from high-polish jet-black onyx, measuring approximately 1.5 to 2 inches in height. The mask is secured in a heavy bezel surrounded by a decorative granulated or beaded silver border. The cuff itself is constructed of split-wire shanks, adorned with multiple applied silver 'sunburst' or 'concho' style floral buttons that display intricate stamping. The silver exhibits a heavy, dark patina within the recessed areas, which provides a high-contrast relief against the polished highlights—a classic hallmark of mid-20th-century Mexican silversmithing. While the back of the cuff is not visible, these items typically date from the 1940s to the 1960s and often carry '925' or 'Taxco' stamps. Condition appears very good, with no visible cracks to the stone; however, there is significant tarnishing consistent with age and expected minor surface abrasions on the silver. The craftsmanship suggests a skilled artisan, blending pre-Hispanic motifs with Art Deco-influenced silverwork.
