Vintage Gold-Tone Green Enamel Geometric Link Earring

This item is a vintage-style earring featuring four geometric, square-shaped links connected by gold-tone jump rings. The earring is constructed from a non-precious base metal with a matte gold-colored finish. Each square link is inlaid with a variated green enamel or resin coating. The colors transition from a light lime green on the uppermost link to a deep forest green and a mottled teal-green on the lower links. The earring appears to be a clip-on or post-style drop earring, though the exact back mechanism is partially obscured. The construction quality suggests mid-range costume jewelry, likely from the late 20th century, approximately the 1980s or 1990s, given the chunky gold-tone aesthetic. In terms of condition, there is visible surface wear including minor scuffing on the enamel surfaces and slight tarnishing or rubbing on the gold-tone finish at the edges and connection points. No maker's marks or hallmarks are immediately visible in this view. The piece exhibits a brutalist or geometric modernist influence through its bold shapes and high-contrast color palette.
