Lapis lazuli and silver-tone jewelry suite in the Southwestern or Andean folk style

This four-piece jewelry suite appears to be composed of a necklace, a bracelet, a pair of drop earrings, and a ring. The pieces feature teardrop-shaped cabochon inlays of a deep blue material with visible Pyrite inclusions, which is stylistically consistent with lapis lazuli. The metal settings appear to be silver or a silver-toned alloy; however, no hallmarks or fineness stamps (such as '925') are clearly visible in the image to verify the metal's purity. Each piece utilizes a minimal bezel setting connected by cylindrical bar links and simple hook-and-eye or French wire closures. The jewelry's design, characterized by geometric shapes and inlaid stone, is consistent with midway to late-20th-century artisanal work from South America (notably Chile or Peru) or the Southwestern United States. The ring shows a singular teardrop inlay on a simple band. The necklace features a central pendant drop. Surface wear and light oxidation are visible on the metal surfaces, suggesting age and prior use. Because no maker’s mark or brand identification is present, the attribution remains hypothetical and based solely on visual aesthetics and typical construction methods associated with these regions.

I have evaluated this four-piece jewelry suite based on the provided images. The set, featuring teardrop-shaped lapis lazuli inlays, displays characteristics consistent with mid-to-late 20th-century artisanal work from South America or the Southwestern United States. Based on what I can see, the deep blue stones contain pyrite inclusions typical of lapis lazuli, though I cannot verify their natural origin or the purity of the silver-tone metal without physical testing or visible '925' hallmarks. My valuation assumes the metal is sterling silver and the stones are natural; if the metal is a base-alloy 'alpaca' or the stones are synthetic, the value would likely drop below $100. The current estimate reflects the market demand for complete, matched vintage sets in the Andean or Folk styles, which generally command higher interest than individual pieces. Surface oxidation and wear suggest previous use, which is typical for this category. To provide a more precise valuation, an in-person examination is required to check for hidden marks, verify the metal's fineness through acid testing, and assess the stones under magnification. The attribution to a specific region remains a hypothesis; should the set be linked to a known master craftsman through provenance documentation, the value could exceed the current range. Conversely, if it is a mass-produced reproduction in the style of these traditions, the value would be on the lower end of the spectrum.
