Blue and Clear Gemstone Cocktail Ring in Cluster Style

This piece features a prominent oval-cut blue stone—possibly synthetic sapphire, glass, or spinel—surrounded by a irregular cluster halo of smaller, round brilliant-cut clear stones (which may be cubic zirconia, glass, or white stones). The stones are set in multi-prong mountings on a gold-toned or yellow metal band featuring split-wire or grooved shoulders. The overall aesthetic is consistent with mid-to-late 20th-century fashion or costume jewelry design. No internal hallmarks or maker's marks are visible in the provided image; hence, exact metal composition and gemstone identity cannot be confirmed without professional gemological and metallurgical testing. Note: The owner attributes this ring as 14k gold over sterling silver and signed 'Spinel', though these claims remain unverified as interior stamps are not shown.

Based on the provided image, I can observe a blue and clear gemstone cluster cocktail ring featuring an oval-cut central blue stone surrounded by an irregular halo of round brilliant-cut clear stones. The setting appears to be a yellow metal with split-wire or grooved shoulders. Per user submission, the ring is attributed as 14k gold over sterling silver and signed 'Spinel'. However, I cannot verify metal purity, gem identity, or internal markings from a photo alone. Assuming the owner's description is correct—that this is a gold-plated sterling silver mounting set with synthetic or natural spinel and cubic zirconia/glass accents—the estimated fair market value is $40–$80. This range reflects typical secondary market demand for mid-to-late 20th-century fashion and vermeil costume jewelry in good pre-owned condition. Without physical testing, I cannot rule out that the base metal is brass or another alloy, or that the center stone is simple glass or plastic. If the piece is confirmed to be base metal costume jewelry rather than gold-over-silver, the secondary market value would likely decrease to approximately $10–$25. Conversely, if in-person gemological testing were to reveal a natural, high-grade gemstone set in solid karat gold, the value would increase significantly. To establish a firmer valuation, a physical inspection by a qualified jeweler or gemologist is required. This would include XRF or acid testing for metal content, gemological testing to identify the refractive index and origin of the stones, and a close examination of any interior hallmarks or signatures under magnification.
