Modernist Graduated Concentric C-Hoop Pierced Earring

This single earring is a bold, modernist C-hoop design featuring a high-polish metallic finish in a warm yellow gold tone. The piece is constructed with a distinctive stepped or concentric relief pattern, where the outer rim flares outward and the inner section recedes into a deep groove, creating a three-dimensional, architectural silhouette. It is crafted with a flat-back profile, indicating the piece is likely hollow-cast or stamped to manage weight despite its substantial visual scale. The earring utilizes a traditional post-and-nut fastening system, featuring a straight surgical steel or base metal post extending from the top edge. The surface exhibits significant light reflection, though visible micro-scratches and minor surface tarnish are present, suggesting it is gold-plated over a base metal rather than solid gold. There are no visible maker's marks or purity stamps on the front or interior edges shown. The style is consistent with late 20th-century fashion jewelry, specifically the 1980s to early 1990s aesthetic of large-scale, sculptural accessories. The craftsmanship demonstrates smooth edges and a clean geometric flow, typical of high-quality vintage costume jewelry.
