The motif is a crane, perhaps? Anyway, it's a bird motif. There are hallmarks for K18 and silver, and it has pearls and something that looks like gemstones, but I don't know the details very well. It became reasonably clean after polishing, but there are scratches and stains. I don't know the original item well, and the pin is slightly bent. This is an item for sale with scratches and stains. If there is anyone who would like to purchase it, please be sure to look at the product page and images very carefully and be satisfied with them. It will be placed in a bag, wrapped in bubble wrap, sandwiched in cardboard, and shipped in an envelope via Yu-Yu Mercari Mail from the post office. I apologize for the inconvenience, but I would appreciate it if you would consider purchasing after looking at my profile. I do not negotiate discounts. I look forward to your purchase. Thank you for reading to the end. #k18 #silver #brooch #birdmotif #crane #bird
