This is a diamond and platinum ring. I purchased it about 7 years ago at a department store for approximately 150,000 yen. I do not know the detailed specifications. No warranty card, no accessories, and the size is unknown. I think it was probably a size 7, but I'm not certain, so please refer to the inner diameter in the photos. I have also included information from AI, so please feel free to research it yourself. It is "without noticeable scratches," not "without any scratches." I have only visually inspected it and have not had it professionally examined. There are many uncertainties, but I would like to sell it to someone who understands this. (I cannot check the item every day, so if any dirt is found during the visual inspection before shipping, I will negotiate a cancellation.) Returns and exchanges are not accepted. * Simple packaging, and will be shipped via post mini (dropped off at the post). Material: Platinum Decoration: Diamond
