Large Oval Purple Stone Cabochon Ring with Filigree Setting

The item is a large, oval-shaped cabochon ring, predominantly featuring a vibrant purple stone with striking iridescent golden-brown or bronze metallic inclusions, suggesting it might be a variety of turquoise, possibly Mohave Purple Turquoise, or a similar composite stone. The stone is set in a substantial silver-toned metal mounting, which appears to be sterling silver, indicated by the '925' context. The metal setting features intricate, openwork filigree or cut-out designs along the shoulders and sides of the ring band, creating an ornate yet bold aesthetic. The overall construction appears sturdy, suggesting good craftsmanship. The surface of the metal shows a bright, polished finish with no obvious signs of significant tarnish or heavy wear. The stone itself seems to be in excellent condition, with a smooth, glossy surface and no visible chips, cracks, or abrasions. The ring's design, with its large central stone and decorative metalwork, points towards a contemporary or possibly vintage Southwestern style, though it lacks definitive maker's marks visible in the image to confirm origin or exact age. Its robust size and eye-catching color make it a statement piece.
