This is a large pearl necklace from Tasaki Pearls. As it is a natural material, there are some scratches and imperfections, but they are large pearls with a beautiful luster. There are no visible stains or flaws from use. The pearl sizes vary slightly, so I measured several of them. Please refer to the images. Due to the simple measurement method, there may be slight errors, but I believe most of the pearls are 9.5mm or larger. I'm not sure how to fasten the necklace; it seems to hook on, but I'm not certain. If anyone knows how to use this type of clasp, please let me know.
