Single Stone Ring Appraisal

Vintage Art Deco Style Single-Stone Ring

This item is a ring featuring a prominent, rectangular cut, deep blue gemstone set in a yellow or rose gold-toned metal band. The central stone appears to be an emerald cut or similar rectangular facet, exhibiting a saturated blue hue, possibly a sapphire or a synthetic spinel/glass imitation. The stone is horizontally oriented on the finger. The setting is notable for its Art Deco influences, characterized by geometric, angular elements surrounding the stone. Specifically, the bezel or prongs holding the stone feature distinct corner details that extend outwards, forming stylized, somewhat notched or stepped structures at each corner, adding to the architectural feel of the piece. The band itself appears relatively simple, tapering towards the shoulders. The metal exhibits a warm, golden luster, though without closer inspection, it's difficult to ascertain if it's solid gold, gold-filled, or plated. There are no visible maker's marks or signatures in the provided image. The overall condition appears good, with no obvious major damage like chips to the stone or significant scratches to the metal, though a light patina consistent with age might be present on the metalwork. The design suggests a style period from the 1920s to 1940s, indicative of the Art Deco or early Retro eras, emphasizing bold lines and central stones. The craftsmanship seems solid, with the stone securely set, indicating a well-made, possibly antique or vintage piece of jewelry.
