Pretty sure its silver , but no markings. Condition: Pre-Owned -- See Photos No Original Box / Pouch – Shipped wrapped in protective layer in small plastic baggie inside a small USPS priority box I do my best to capture as much detail as possible and highlight any obvious flaws. However, there are instances where I may miss something or the photo may not capture everything. Some brooches contain many small jewels, making it difficult to spot if one is missing. Additionally, some scratches may only be visible in certain light conditions. Although I strive to capture and report these, please note that brooches are being sold as-is in pre-owned condition and may include imperfections not noted or seen in photos.
