Modernist Silver-Tone Circular Open-Work Pendant Necklace

This piece of fashion jewelry consists of a large, circular pendant suspended from a long rope-style chain. The pendant features a modernist, open-center design with a highly polished silver-tone finish on the upper half and a textural, interlocking wave or chain-link open-work pattern on the lower crescent. A decorative square-set element, possibly containing a dark inset or hallmark area, serves as the bale connecting the pendant to the chain. The chain itself is a tightly woven rope link, common in mid-to-late 20th-century costume jewelry, ending in a lobster claw clasp with a short extender. The overall construction suggests a contemporary or late vintage 1990s style, likely made of a base metal alloy with rhodium or silver plating. The condition appears fair to good; there is visible surface scratching on the polished portions of the pendant consistent with regular wear, and the silver plating shows slight dullness in the recessed areas of the intricate latticework. The piece lacks obvious high-end gemstones, placing it in the category of decorative accessory jewelry rather than fine metalwork.
