This was a gift purchased overseas a while ago. I had it appraised at a secondhand shop before, and they said the hallmark is unclear, but it's likely 585 (14k gold). The stone is not a diamond. I believe it's CZ or something similar. Weight: Approximately 1.3g This is a pendant top only, and there are no other accessories. A chain is not included. Please forgive any oversights. Although it has been used infrequently, please understand that this is a pre-owned item that has been stored at home before purchasing. If you have any concerns or questions, please comment before purchasing. However, I will not answer questions about the purchase price. If you purchase two or more items that can be shipped together using the same shipping method, I can offer a small discount. Please comment before purchasing. Please refrain from cancellations, returns, or complaints after purchase. The actual color may differ slightly depending on the computer or smartphone you are using. We cannot accept complaints or returns based on reasons such as "it was different from the image" after you receive the item, so please only transact with those who can definitely provide a receipt evaluation. We plan to ship via Yu-Packet Post, which is trackable and anonymous, mainly using recycled materials. 0430-C0179-260101-014-0122
