Pair of oval costume earrings in the vintage style

A pair of oval-shaped earrings, approximately 20-25mm in length based on proximity to the adjacent pen. These items feature a central, dark-colored cabochon which appears to exhibit a chatoyancy or cat's-eye effect, stylistically consistent with synthetic fiber-optic glass or tiger's eye. The stones are bezel-set within a silver-toned metal surround characterized by a textured, ornate border featuring circular and geometric motifs. This pattern is reminiscent of late 20th-century costume jewelry design. The metal displays a dark patina or intentional oxidation in the recessed areas to enhance the detail. No maker’s marks or hallmarks are visible in the provided image, so the specific manufacturer and metal composition (e.g., silver-plated base metal) remain unverified. The craftsmanship appears consistent with mass-produced fashion accessories of the late modern era. Condition appears fair, with visible surface grime and minor oxidation consistent with age and storage. In-person inspection is required to determine the mounting type (clip-on or pierced) and material purity.

Based on my visual analysis of the provided image, these appear to be vintage-style costume jewelry earrings featuring chatoyant synthetic stones or glass cabochons. I cannot determine the exact material composition from a photograph; while they have a silver-toned appearance, I cannot verify if they are sterling silver or a plated base metal without a physical inspection for hallmarks or acid testing. The intricate, textured borders suggest a late 20th-century mass-produced design rather than a bespoke or high-jewelry origin. The value I have assigned reflects the current secondary market for unattributed fashion accessories of this era. This estimate assumes the items are standard costume jewelry; if they were found to bear a mark from a highly sought-after designer of that period, the value could potentially double. Conversely, significant wear or plating loss not visible in the photo would reduce the value to a nominal amount. Because I can't verify the mounting type or the presence of maker's marks, this remains a working hypothesis. General market demand for generic vintage costume jewelry remains stable but modest, with most interest coming from collectors of 'boho' or 'retro' aesthetics. To finalize a valuation, an in-person examination is necessary to check for signatures, assess the setting security, and determine metal purity. Without such verification, they should be treated as decorative fashion pieces rather than fine jewelry.
