Vintage Oval Tiger's Eye Costume Brooch

This is a vintage oval-shaped brooch featuring a large, polished tiger's eye cabochon as its centerpiece. The gemstone displays characteristic chatoyancy with vertical bands of golden-yellow, brown, and honey hues. The stone is held in place by four prominent silver-toned metal prongs. The bezel is surrounded by an intricate decorative frame consisting of a beaded or 'milgrain' border, further accented by clusters of spheres or granules on the horizontal axes, suggesting a Victorian revival or Mid-century costume jewelry style. The metal appears to be a copper or brass base with a silver-toned plating that shows significant oxidation and verdigris, particularly around the granulated details. The condition is consistent with age, showing a heavy patina and some surface grime, which obscures any potential maker's marks. The construction is robust but indicative of mass-produced costume jewelry rather than fine jewelry, likely dating from the mid-20th century (circa 1950s-1970s). The piece measures approximately 1.5 to 2 inches in length based on scale.
