Vintage 12k Gold Plated Emerald Green Rhinestone Floral Brooch Pin

This is a vintage brooch pin, styled as a floral bouquet, featuring several emerald green rhinestones and a 12k gold plated finish. The pin depicts a bundle of stylized flowers and leaves, meticulously arranged to form a bouquet. There are at least four prominent round-cut, faceted emerald green rhinestones, each individually bezel-set, representing the flower blooms. These stones exhibit striking clarity and a vibrant green hue. Interspersed among the rhinestones are smaller, textured gold-toned floral elements, possibly copper-toned or with a coppery patina, adding depth and contrast. Two larger, smooth, elongated leaves with a slightly curved, polished surface flank one side of the bouquet, creating a sense of movement. The stems of the bouquet are gathered and bound near the base by a wrapped design, simulating a tied natural bouquet. Below the leaves, a decorative swirl element with a small, raised, circular accent (also with a copper-like tone) adds further embellishment. The overall construction appears to be a combination of cast and wire-formed elements, showcasing good craftsmanship for a costume jewelry piece. The gold plating, stated as 12k, shows some minor wear consistent with its vintage nature, particularly on raised edges and high-traffic areas, revealing a slightly darker base metal in some spots, which could contribute to the copper-tone appearance on some details. This wear, along with a possible subtle tarnish, suggests an estimated age spanning from the mid-20th century, likely 1940s to 1960s. No specific maker's marks or stamps are visible from the provided image, which is common for many vintage costume jewelry pieces. The pin mechanism, while not fully visible, is implied by its function as a brooch, typically involving a hinged pin and a clasp. This piece represents a classic mid-century floral design, offering a touch of vintage elegance.
