Vintage Sterling Silver and Inlaid Shell Navette Drop Earrings

This is a pair of vintage navette-shaped drop earrings crafted in sterling silver, featuring central inlaid sections of iridescent shell, likely paua or abalone. The earrings are characterized by an elongated, pointed oval silhouette measuring approximately 1.5 to 2 inches in length. The construction technique utilizes a multi-layered design: a central polished shell sliver is bezel-set and surrounded by a border of decorative silver work including twisted wire rope detailing and granulation (tiny silver beads). This ornate silver work sits within an outer recessed oxidized frame that provides depth and contrast to the brightly colored shell. The shell insets exhibit a high degree of iridescence with visible flashes of green, blue, pink, and gold. The earrings are suspended from simple French hook ear wires, one of which appears slightly bent, indicating a softer silver alloy common in handcrafted jewelry. The silver exhibits a heavy natural patina and tarnishing, particularly in the recessed areas, which is consistent with age and emphasizes the texture of the wirework. While no maker's mark is visible on the front, the style and craftsmanship are indicative of mid-20th-century artisan work, possibly within the Southwestern United States or Mexican silver tradition. The items show minor surface wear and oxidation consistent with a vintage or antique estate origin.

I have completed a visual examination of these vintage sterling silver and inlaid shell navette drop earrings. The craftsmanship displays classic mid-20th-century artisan techniques, most likely originating from the Mexican Taxco or Southwestern U.S. jewelry traditions. The use of abalone/paua shell paired with rope-twist wire and granulation is indicative of a time-intensive, handcrafted process. The condition is graded as good-vintage; the heavy patina is desirable for collectors as it proves age and highlights the repoussé-style depth, though the bent French hook suggests some fatigue in the silver alloy. The market for mid-century ethnic and artisan silver remains stable. Comparables for unsigned sterling shell inlay navette earrings typically sell within the $100 to $200 range at boutique estate auctions or specialized vintage marketplaces. The value is driven by the iridescence of the shell and the intricacy of the silver frame rather than raw material weight. Limitations to this appraisal include the inability to verify metal purity via acid testing or XRF analysis. While the construction suggests sterling silver (.925), many pieces of this era vary in fineness. Furthermore, the absence of a visible hallmark makes it difficult to attribute the work to a specific renowned silversmith, which would significantly increase the value. A full physical inspection would be required to rule out shell doublets or synthetic laminates and to confirm the absence of hidden hallmarks on the reverse of the bezel. To finalize provenance, I would recommend checking for faint '925' or 'Hecho en Mexico' stamps under 10x magnification.
