Pair of faceted purple gemstone stud earrings in silver-toned settings

This item consists of a pair of stud earrings featuring round, faceted gemstones of a medium-to-vibrant purple hue, consistent with the appearance of amethyst or a similar synthetic material. Each stone is secured within a multi-pronged basket setting made of a silver-toned metal, which exhibits a slightly textured or decorative gallery design. The settings include traditional post backs with friction butterfly clutches. The metal appears to have a cool-toned luster, which is stylistically consistent with sterling silver, white gold, or stainless steel; however, no hallmarks or maker's marks are legible in the provided image to verify the specific metal content. The craftsmanship suggests a contemporary or late-20th-century aesthetic. The facets of the stones appear relatively sharp, though some surface dust or minor abrasions are visible upon close inspection, typical of pre-owned jewelry. Because no identifying branding or stamps are visible, this attribution is based solely on the visual stylistic features of the pieces. Physical testing by a jeweler would be required to determine the specific gemstone identity and metal purity.

Based on my visual examination of the provided image, I have analyzed this pair of purple gemstone stud earrings. The items appear to be faceted stones, consistent with amethyst or synthetic spinel, housed in silver-toned basket settings. While the aesthetic is consistent with sterling silver and natural semi-precious gemstones, I cannot identify the metal purity or the specific mineral species from a photograph alone. No hallmarks or maker's marks are visible to suggest a specific designer or manufacturer. The estimated value of $40–$120 assumes the materials are sterling silver and natural amethyst. This range reflects typical secondary market pricing for unbranded contemporary silver jewelry. On the higher end of the range, the value assumes the stones have high clarity and the settings show minimal wear; on the lower end, it accounts for the visible surface dust and potential minor abrasions. If physical testing were to reveal the metal is a non-precious alloy or the stones are glass or plastic, the value would likely drop below $15. Conversely, if the settings were found to be 14k white gold, the value would increase significantly based on gold weight. To reach a more precise valuation, a physical inspection by a jeweler is necessary to test for metal fineness (via acid or XRF testing) and to conduct gemological tests such as refractive index measurement. The current estimate is a hypothesis based on visual style and would be refined by the presence of verified hallmarks or provenance documentation.
