Vintage Blue Rhinestone Floral Brooch

This is a vintage brooch, meticulously crafted in the form of a five-petaled flower, showcasing a captivating array of blue rhinestones. The central cluster of the flower features five larger, marquise or oval-cut rhinestones in a vibrant, slightly lighter shade of aqua or turquoise blue, arranged in a star or pinwheel pattern around a presumably small central element not clearly visible. Each of these central stones is multi-faceted, allowing for significant light refraction. The five surrounding petals are elaborately embellished with numerous smaller, round-cut rhinestones in a darker, sapphire blue hue, giving the petals a textured and shimmering appearance. The metal setting appears to be a dark-toned silver, possibly gunmetal or oxidized silver-plated, which provides a strong contrast to the bright blue stones and enhances their sparkle. The construction suggests individual prong settings for many of the smaller stones, ensuring their security and maximizing their brilliance. There are no visible maker's marks or signatures from the provided image, common for many vintage costume jewelry pieces. The condition appears to be excellent, with all rhinestones present and no obvious signs of wear, damage, or missing elements. The brooch likely dates from the mid-20th century, possibly 1950s-1970s, based on its design ethos and use of vibrant rhinestones characteristic of that period in costume jewelry. The overall craftsmanship indicates a well-made piece of costume jewelry, designed for visual impact and decorative appeal.
