Vintage-Style Two-Tone Mesh Collar Necklace with Aurora Borealis Focal

This is a substantial collar-style necklace featuring a thick, silver-toned woven mesh chain that provides a flexible yet structured drape. The centerpiece of the necklace is a large, circular pendant with an ornate, multi-layered texture. The focal element showcases a central oval faceted glass stone with an 'Aurora Borealis' (AB) coating, which reflects a spectrum of iridescent blues, pinks, and golds. This stone is bezel-set and surrounded by two distinct rings of 'caviar' or beaded metalwork: an inner ring of silver-toned spheres and an outer ornamental border of gold-toned beads. The pendant is flanked by two decorative silver-toned end caps featuring matching beaded bands, which transition the medallion into the mesh chain. The construction suggests a late 20th-century fashion piece, likely a costume jewelry design inspired by high-end 'Byzantine' or 'Bali' silver styles. The condition appears excellent with no visible tarnishing or missing beads; the metallic finish shows a slight antiqued patina in the recessed areas to enhance the detail of the metalwork. The iridescent coating on the centerpiece remains vibrant and free of major surface scratches, indicating a well-preserved piece of contemporary costume jewelry.
