It has been used only a few times, and there appears to be no noticeable damage to the naked eye. There are some minor scratches and discoloration upon close inspection. The stone is not a diamond, but a zirconia, which sparkles beautifully. If you don't need the box, I can protect the earrings with bubble wrap and ship them via Yu-Packet, etc. If you want the box, it will be sent via Takkyubin (home delivery service). Therefore, if you don't need the box, please comment. I can offer a discount.
