I fell in love with the beautiful green color and purchased these earrings at GEMS GALLERY (a jewelry store) in Bangkok, Thailand. They are new, unused, and have been stored at home. The earring backs appear to be stamped with "925" and a mark. I purchased these several years ago, and the details of the stones are unclear, so I will leave them as unknown. - Stone: Details unknown - Material: Stamped with what appears to be "925" on the earring backs - Size: Approximately 1.0cm - Design: Green stone in the center, surrounded by diamond-like stones I purchased these in Thailand several years ago. I forgot I had them and they have been stored unused. I am selling them because I closed my ear piercings. I am not knowledgeable about gemstones, and my memory is vague. There is a stamp and some kind of mark on the earring backs. Please do not purchase if you are concerned about minor details. These are high-end items, so returns and refunds are not possible to prevent switching. Thank you for your understanding. I will ship them via anonymous delivery in a GEMS GALLERY accessory pouch. Thank you for looking.
