Vintage Green Leaf Brooch with Pin Back

This item is a vintage-style brooch, primarily featuring a botanical, likely floral, motif. The main body of the brooch consists of several layers of green elements, which appear to be sculpted or molded to represent leaves. The green color is a soft, somewhat muted sage or mint green, suggesting a material like ceramic, porcelain, glass, or possibly an enamelled metal or molded plastic, with a matte or satin finish. The edges of these "leaves" are ruffled and organic, mimicking natural foliage. At the center, partially obscured, is what appears to be a lighter colored element, possibly a small flower or cluster of stamens, though its details are not clearly visible from this angle. The reverse side, which is fully visible, features a silver-toned metal pin mechanism. This mechanism is a standard hinged pin bar with a simple 'C' clasp closure. The metal part is oval-shaped and shows signs of age, including some tarnishing and a slightly dull, speckled appearance, indicative of wear and oxidation. There are no clear maker's marks or signatures visible on the pin mechanism in the provided image. The construction suggests a piece from the mid-20th century, a common period for this type of costume jewelry. The overall craftsmanship appears to be reasonably intricate for the leafy elements, though the pin attachment is simple. The condition appears to be consistent with age, with the metal showing some patina but no obvious catastrophic damage to the green elements, though light wear or minor chips cannot be fully ruled out without a front view.
