Vintage-Style Horseshoe Patterned Hoop Earring

This item is a single hoop earring featuring a distinctive 'U' or horseshoe shape with an antiqued, dark silver-tone finish. The piece is constructed from a non-precious base metal with a heavy patina, likely achieved through burnishing or chemical oxidization to give it a gothic or vintage aesthetic. The exterior surface is decorated with a series of recessed patterns, including raised circular studs and geometric shapes such as squares and diamonds. These geometric windows are set with small, faceted clear and dark-colored glass stones or synthetic crystals, including a notable square-cut black stone. The earring uses a post-style fastening with a standard tension back and a clear plastic comfort disc, which appears slightly yellowed, indicating some age or exposure. The overall craftsmanship suggests a mass-produced fashion jewelry item from the late 20th to early 21st century. While the user mentions a 'reverse watch,' this specific image shows a costume jewelry earring with moderate surface wear and some dulling of the metallic luster, consistent with regular use.
