This is a pearl necklace. As it is natural pearl, there may be imperfections and irregularities on the surface formed during the growth process. Pearl size: Approximately 8mm This pearl necklace was sold in the showcase of my family's jewelry store. It is new and unused, but it has been stored for a long time, so it is being offered at a low price considering the aging. If you are concerned, you can have the thread replaced or have maintenance done to restore the shine (such as polishing), and you can enjoy it in a beautiful condition almost like new. This is recommended for those who are looking for pearls at a slightly better price. We will consider price negotiations, so please feel free to comment if you are interested.
