Vintage Garnet Cabochon and Dual-Tone Filigree Ring

This is a vintage or antique cocktail ring featuring a prominent cabochon gemstone, likely a garnet given its deep reddish-brown hue and opacity. The ring's design is elaborate and multi-layered, showcasing a combination of silver-tone and gold-tone metals. The central cabochon is set within a bezel of what appears to be gold or gold-plated metal, which is further surrounded by intricate filigree work in the same gold-tone material. This gold-tone filigree adds a delicate, decorative border to the bezel. Surrounding this central golden element is a larger, petal-like or scalloped frame made of silver-tone metal, possibly sterling silver, which gives the ring a floral or rosette appearance. The silver-tone elements of the ring, including the band visible toward the bottom, exhibit some tarnish and patina, consistent with age and typical wear for silver. The overall construction suggests a handcrafted piece, with the various metal components skillfully joined. The craftsmanship appears to be of good quality, with attention to detail evident in the filigree and the shaping of the silver frame. There are no obvious signs of significant damage like cracks or chips; the gemstone appears intact, and the metalwork seems structurally sound, though surface wear and tarnish are present, contributing to its aged aesthetic. The style hints at an early to mid-20th century design, possibly Arts and Crafts or Art Nouveau inspired due to its organic forms and prominent central stone, or perhaps a more generalized vintage ethnic-style piece.
