Cultured Pearl. Color - off-white with a slight pink hue. Size: Please refer to the authentication certificate. I purchased this from the Mercari app last year, 2023. From the day I received it, I truly admired it and kept it safe, often looking at it when I was feeling down. It brought me joy to see such a beautiful item. However, it's been a year now, and I've realized I haven't had the opportunity to wear it, so I've decided to sell it. The condition is good; you wouldn't know it's a used item. The size is also perfect for casual wear with t-shirts and shirts (kamis).
