Sterling Silver and Blue Cabochon Ring

This is a vintage or antique ring featuring a prominent oval-shaped, smooth blue cabochon stone set in a sterling silver mounting. The stone exhibits a vibrant, somewhat variegated blue hue, with lighter and darker streaks or marbling that suggest a natural material, possibly chalcedony, agate, or a glass imitation like a plique-à-jour enamel or even an older mood stone. The cabochon has a high dome and a polished surface, showing some natural inclusions or imperfections upon closer inspection, though no significant chips or cracks are visible. The setting is crafted from sterling silver, characterized by its darkened patina, which has settled into the recessed areas, highlighting the intricate details of the design. The sides of the central stone are flanked by decorative elements that appear to be stylized leaves or scrolls, possibly representing a floral or botanical motif, tapering off towards the band. These elements are finely detailed, showcasing a degree of craftsmanship that indicates higher quality than mass-produced costume jewelry. The silver itself displays some wear consistent with age and use, including minor scratches and surface abrasions, but no major dents or breaks in the metal are apparent. The overall style suggests an age range from the late 19th to early 20th century, possibly Art Nouveau or early Art Deco, given the organic, flowing lines of the silverwork. The small size of the ring, as seen on the finger, implies it might be a pinky ring or suitable for a slender finger. The construction appears sturdy, with the stone securely bezel-set within the silver frame. Without specific maker's marks or hallmarks being visible, a precise attribution of origin or exact age is challenging, but the 'sterling' context provided confirms the metal composition.
