Stacked Three-Ring Set with Opal/Mother-of-Pearl, Oval-Cut Gemstones, and Round-Cut Gemstones

The item consists of three distinct rings stacked on a finger, likely a ring finger, indicating them to be finger rings. The uppermost ring appears to be a wide band, approximately 4-5mm in width, crafted from a yellow-toned metal, presumably gold, with a central inlay that displays a shimmering, pearlescent quality with subtle hints of opalescence, suggesting it might be mother-of-pearl or opal. Its surface appears smooth and polished, without any visible significant wear or damage. Below this, the middle ring is a yellow-toned metal eternity or half-eternity band, set with a series of approximately five or six oval-cut, colorless gemstones. These stones are individually bezel-set within the gold, showcasing high-quality craftsmanship, as the settings appear secure and uniform. The gemstones exhibit good clarity and brilliance. The lowermost ring is another eternity or half-eternity band, presenting a more delicate appearance than the middle ring. It is crafted from a silver-toned metal, likely white gold or platinum, and is set with numerous round or brilliant-cut, colorless stones. These stones are smaller than those in the middle ring and appear to be prong-set, allowing for maximizing their sparkle. All three rings are in good visible condition, with no obvious signs of significant wear, scratches, or missing stones. The metal appears to retain its original luster. The overall style suggests a contemporary or classic aesthetic, suitable for stacking. No visible maker's marks or signatures are discernible from the image. The unified appearance of the stacked rings suggests they may be sold as a set, or are intentionally worn together to create a layered look.
