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.

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.
