Vintage 18kt White Gold Cluster Ring with Marquise-cut Center Stone

This is a vintage cluster ring, likely crafted from 18 karat white gold as indicated by the context. The ring features a central marquise-cut gemstone, which appears to be dark blue or teal in color, securely set within a bezel or partial bezel. Surrounding this central stone is a cluster of smaller, round-cut gemstones. These smaller stones exhibit a light yellow-green hue, suggesting they might be peridots, demantoid garnets, or possibly diamonds with a yellowish tint, although a definitive identification without closer inspection is not possible. The overall shape of the cluster head is an elongated oval, reminiscent of a navette style, creating a decorative visual impact. The setting for the cluster stones appears to be a shared-prong or bead setting, allowing for maximum light exposure to the individual gems. The band of the ring is a slender, polished shank, suggesting a delicate construction. While the image quality limits the precise assessment of wear, some minor surface scratches on the metal or slight dulling of the stones' brilliance might be present, consistent with a vintage piece that has been worn. There are no visible maker's marks or signatures discernible from the provided images. The design suggests an aesthetic popular from the mid-20th century, possibly the 1950s to 1970s, characteristic of a cocktail ring or a dress ring. The craftsmanship appears to be of good quality, with stones well-matched for size and color within their respective groups, indicating careful selection and setting for optimal aesthetic appeal. The piece has a distinct classic and elegant vintage appeal.
