Oxidized Copper Alloy Filigree Crescent Pendant

This item is a crescent-shaped open-work pendant, likely crafted from a copper-based alloy such as brass or bronze, evidenced by the heavy greenish-blue verdigris oxidation covering the surface. The pendant features an intricate, symmetrical filigree design characterized by swirling, stylized patterns that suggest a tribal or folk-art influence. Structurally, it is a flat, thin metallic piece with two small suspension holes integrated into the upper tips of the crescent, intended for attachment to a chain or cord. The construction appears to be a stamped or cast metal process rather than hand-wrought wirework. The condition shows significant environmental weathering and surface corrosion, which has dulled the original metallic sheen and created a matte, textured patina. There are no visible maker's marks or stamps on the front-facing surface. Its style is evocative of mid-20th-century costume jewelry or perhaps a souvenir piece replicating ancient or ethnic aesthetics. The craftsmanship is modest, with somewhat uneven interior edges in the cutouts, indicating a mass-produced or artisan-level quality rather than fine jewelry. The piece likely dates to the late 20th century.
