Silver-tone cocktail ring with blue cabochon and filigree details

This appears to be a silver-tone cocktail ring featuring a large, oval-shaped cabochon stone with a light blue and white mottled pattern, which is stylistically consistent with the appearance of Larimar. The stone is secured by multiple prongs within an ornate, wide-shouldered setting. The shoulders and gallery of the ring are decorated with intricate filigree and scrollwork motifs, accented by small, round colorless stones that are consistent with white topaz, cubic zirconia, or small diamonds. A small, partially obscured hallmark is visible on the interior of the shank, which appears consistent with '925', potentially indicating sterling silver content, though this is unverified without metal testing. The craftsmanship shows a combination of cast elements and detailed metalwork, suggestive of contemporary jewelry designs influenced by Edwardian or Art Deco revival styles. The piece shows minor surface scratches and slight oxidation in the recessed areas of the filigree, which is typical for pre-owned silver jewelry. Because the hallmark is not fully legible and the stones cannot be tested through a photograph, this identification remains a hypothesis based on visual characteristics alone. Physical inspection by a jeweler would be required to verify the silver purity and the identity of the gemstones.

Based on my visual analysis of the provided image, this cocktail ring appears to be a contemporary piece crafted in a revival style, possibly featuring a Larimar cabochon set in sterling silver. I can identify what appears to be a '925' hallmark on the inner shank, which suggests a silver purity of 92.5%, though I cannot verify the metal content or the stone's identity without physical testing. The blue-and-white mottled stone is consistent with the visual characteristics of Larimar, while the colorless accents bear a resemblance to white topaz or cubic zirconia. From the photo, I can see minor surface wear and oxidation in the filigree, which is typical for pre-owned silver jewelry. My valuation is based on the assumption that the materials are sterling silver and natural Larimar. The market for Larimar jewelry remains steady due to its limited geographical source, although mass-produced silver settings generally trade in a lower price bracket compared to designer-label or hand-forged pieces. The value estimate reflects the current secondary market for unbranded sterling silver fashion rings. If physical inspection were to reveal that the stone is a synthetic simulant or that the metal is a silver-plated base metal, the value would likely decrease to under $20. Conversely, if the accent stones were determined to be natural diamonds of significant quality, the value could increase. To confirm this estimate, an in-person examination by a qualified jeweler is necessary to perform a streak or acid test on the metal and use a refractometer to identify the gemstones. Confirming the hallmark's legitimacy and the stone's origin would be essential for a more precise valuation.
