I purchased this at a jewelry store around 2019. I've lost the appraisal certificate, so I'm not certain of the pearl type, but it's not an imitation. The color is natural, and I bought it from a reputable jewelry store. The color is close to blue-gray. I've only used it for formal occasions, so I think it's in good condition. The diameter of the pearls is about 7mm. The rose clasp decoration is silver. I will also include a buckskin pouch (I think it's buckskin, it's a drawstring bag I received from the jewelry store). Length: Approximately 46cm The length can be adjusted within the 46cm range using the rose clasp's magnetic closure. I don't have the original box, so I will wrap it in bubble wrap for packaging. I will ship it via either Rakuraku Mercari Bin or Yu-Yu Mercari Bin.
