Vintage Southwestern-Style Sterling Silver and Onyx Teardrop Clip-on Earrings

A pair of vintage clip-on earrings featuring a teardrop-shaped base crafted from a silver-toned metal, likely sterling silver given the oxidation patterns. At the center of each earring sits an oval-cut black onyx cabochon, securely set in a bezel mounting. The decorative work is characteristic of Southwestern or Bohemian jewelry, showcasing intricate beadwork (granulation) encircling the central stone and a twisted rope-style border along the outer edge of the teardrop. The metal displays a significant natural aged patina, particularly within the recessed areas of the beadwork, which adds depth and highlights the craftsmanship. The construction appears sturdy, using traditional soldering techniques for the decorative elements. While no maker's mark is visible from the front view, the style is indicative of mid-to-late 20th-century artisan work. The condition shows minor surface wear and tarnishing consistent with age, but the stones remain intact with a high-polished luster and no visible chips or cracks. The clip-on mechanisms are not visible but are presumed to be standard hinge-style fasteners common to this era of costume and sterling jewelry.

I have carefully examined the images provided of these vintage Southwestern-style clip-on earrings. My visual inspection confirms they are characteristic of mid-to-late 20th-century artisan jewelry, likely originating from the 1970s or 1980s. The design utilizes classic motifs including granulation (beadwork) and a twisted rope border, which frame what appear to be high-quality, genuine black onyx cabochons. The oxidation patterns and 'depth' of the patina suggest the base metal is indeed sterling silver (.925), though a hallmark was not visually identified. The condition is 'Good to Very Good.' The stones exhibit excellent luster with no visible surface abrasions, and the age-appropriate tarnish enhances the textural contrast of the metalwork. In the current secondary market, such as online vintage boutiques or estate auctions, there is a steady demand for Southwestern-style accessories due to the enduring popularity of 'Boho-chic' aesthetics. Comparables for unbranded, mid-century silver and onyx earrings typically sell within the $40 to $100 range depending on weight. Several limitations exist with photographic appraisal. Without a physical inspection, I cannot verify the metal purity via a commemorative '925' mark or acid testing. Furthermore, a physical test of the clip-on tension is required to ensure mechanical functionality. Full authentication would require an in-person examination to search for hidden maker's marks and to confirm the stones are natural onyx rather than glass or dyed chalcedony. The lack of a specific artisan's mark (e.g., a known Navajo or Zuni smith) keeps this valuation in the standard vintage category rather than the collectible fine art category.
