Decorative metal button or dress stud

This appears to be a small, round decorative metal fastener or dress stud with an ornate raised geometric and foliate-style design. The surface shows repeating curved bands, bead-like borders, and triangular relief elements, suggesting a pressed, cast, or stamped decorative piece rather than a plain utilitarian button. The finish appears aged and possibly gilt or brass-colored, with significant patina. Based on the single image, it could be a button, cuff stud, or ornamental clothing accessory rather than a standalone jewelry item.

Decorative buttons and studs of this type were common in the Victorian and Edwardian periods, reflecting the era's emphasis on ornamentation in dress accessories and tailoring. Such pieces can be of interest to collectors of antique buttons, costume accessories, and military or formalwear hardware.
