Abalone and metal drop earrings

This pair of drop earrings features a distinctive marquise- or leaf-shaped open metal frame crafted from a silvery-toned base metal, exhibiting a slightly dull patina consistent with vintage costume jewelry. Suspended inside each open frame is an oval-cut piece of iridescent abalone shell, displaying a vibrant play of green, gold, and amber flashes across its surface. Above each abalone stone, near the top suspension loop of the frame, are three small decorative seed beads in muted tones of olive green, blue, and purple. The earrings utilize a leverback closure mechanism for secure wear. There are no visible maker's marks, stamps, or signatures present on the visible portions of the metalwork, so the identification rests entirely on the visual characteristics of the materials used. The overall style suggests a mid-to-late 20th-century artisan or bohemian aesthetic, though the exact period and place of manufacture remain unverified. The construction appears sound, with minor surface wear and oxidation on the metal components consistent with age and previous handling.

Based on what I can see in the provided image, this pair of drop earrings exhibits a vintage bohemian aesthetic, characterized by open silvery-toned metal frames, iridescent abalone inserts, and small seed bead accents. The leverback closures and overall construction suggest a mid-to-late 20th-century origin, though I can't verify from a photo the exact alloy composition or the precise period of manufacture. There are no visible maker's marks or signatures present on the metalwork, meaning that any attribution remains purely hypothetical and based solely on stylistic similarities to artisan-made costume jewelry of the period. In formulating this appraisal estimate, I assume the materials and style are consistent with typical mid-century bohemian pieces, for which general market demand is modest but steady among collectors of vintage costume accessories. However, the metal components show visible surface wear and oxidation, which impacts the overall valuation. Furthermore, an unauthenticated or unattributed piece of this type would typically trade at the lower end of the market scale, whereas a verified maker's mark—if one were somehow obscured—could potentially elevate interest. To fully confirm the materials, age, and any potential maker, physical inspection would be needed, including hallmark verification and potentially metal testing. If this item turns out to be a modern reproduction, replica, or an unbranded 'in-the-style-of' piece rather than a period artifact, the value would realistically adjust downward to roughly $15–$30, reflecting purely decorative costume jewelry value.
