Vintage Gold-Tone Abstract X and O Sculptural Brooch

This is a vintage sculptural pin or brooch featuring a bold, postmodern aesthetic characteristic of 1980s jewelry design. The piece is constructed from a non-precious base metal with a vibrant, semi-matte gold-tone finish. Physically, the item is composed of two primary sections: an upper 'X' formed by two overlapping tubular segments and a lower 'O' or circular donut-shaped component with a deep central depression. The construction is solid and cast, exhibiting smooth, rounded contours that create a high-relief, Three-dimensional profile. The golden finish shows a slight satin sheen rather than a high mirror polish, which highlights the soft curves of the design. Regarding condition, the piece appears well-preserved with minor surface micro-scratches visible upon close inspection, typical of vintage age. There is no significant loss of plating or oxidation apparent on the face. While maker's marks are not visible from the front perspective, the style is consistent with high-end costume jewelry brands of the late 20th century such as Monet or Anne Klein, which often utilized these chunky, architectural motifs. The overall craftsmanship is high, evidenced by the seamless transitions between the organic shapes and the uniformity of the plating.
