Asymmetrical White Enamel Post Earring

This is a single post-style earring featuring a modern, asymmetrical triangular or 'guitar pick' shape with curved edges. The front of the piece is coated in an opaque white enamel finish applied over a metallic base. The earring measures approximately 15mm to 20mm in width. It features a thin metal post soldered to the center of the reverse side, which lacks a butterfly clutch or safety backing in the photograph. The construction is reflective of mid-century modern or contemporary minimalist jewelry styles, likely dating from the 1970s to the early 2000s. The surface shows minor accumulation of dust and fine surface scratches consistent with use. There is visible dark oxidation and tarnish around the base of the post where it meets the earring body, suggesting the base metal is a non-precious alloy or perhaps sterling silver with a high copper content. No maker's marks or hallmarks such as '925' are visible in this orientation, indicating it may be costume jewelry. The overall craftsmanship is functional but simple, with a slightly textured matte-finished reverse.
