This is a vintage item that has been stored at home for a long time. Please understand this before purchasing. As shown in the photos, there are some scratches, stains, and discoloration, as well as rust. The silver ring part is stamped with "SILVER". The material of the stone is unknown. Thank you for viewing! Please refer to the photos for the size and condition. I have taken close-up photos of any areas of concern. I am not considering price reductions for single item purchases. Please refrain from purchasing if you are concerned about any of the above. Items will be packaged using recycled materials and shipped in a compact manner. I have only performed a simple cleaning. Please clean any detailed areas yourself. I am a private seller, so there may be oversights in my inspection. Please understand that this is a used item that has been handled by someone else before purchasing. The color may differ slightly from the actual item due to the monitor environment, the way the photos were taken, and the lighting. *The descriptions are based on my personal opinion, so please refrain from purchasing if you are sensitive to such matters. Multiple purchases are welcome! Please be sure to check the condition in the photos and purchase only if you are satisfied. I will check any points of concern. Basically, refunds will not be accepted, including non-delivery outside of Mercari shipping, and also from the perspective of preventing item substitution.
