Gold-Tone Pavé Crystal Open Heart Pendant Necklace

This item is a contemporary fashion necklace featuring an asymmetrical open heart-shaped pendant suspended from a yellow gold-tone box chain. The pendant displays a 'swirled' or ribbon-like design, where one half of the heart's curve is set with multiple rows of small, clear pavé-set crystals (likely glass or cubic zirconia), while the interior borders of the frame remain polished metal. The construction utilizes a base metal with a yellow gold-colored electroplated finish. The chain is a classic box link style, approximately 1mm to 1.5mm in thickness. Notable features include the integrated bail design where the chain passes directly through the upper portion of the heart. Regarding condition, there is visible tarnish and wear to the gold plating, particularly along the inner edges and the bottom point of the heart, revealing some oxidation or darker base metal underneath. All crystals appear to be present in the image, though their brilliance is slightly muted by Surface grime. This piece belongs to the late 20th to early 21st-century costume jewelry era, mimicking high-end fine jewelry designs from brands like Swarovski or Brighton, but without visible hallmarks in this view to confirm a specific luxury brand.
