This is a ring with diamonds and pearls. Size: 14.5 to 15 (Japanese size) Pearl size: Approximately 8.5mm Type of pearl: Akoya pearl Markings: Pt900, 0.55 Weight: Approximately 7.6g Accessories: None The pearls have a white-pink hue, and they exhibit beautiful pink and green iridescence. The luster and nacre are both excellent, and it is a high-quality pearl without any noticeable blemishes or surface imperfections. In my amateur opinion, I believe it is a Hanadama-class pearl. The diamonds are nearly colorless and transparent, with excellent brilliance. The ring has been polished before listing, so it is in beautiful condition with no particular issues. The case in the image belongs to another ring and is not included. Material...Platinum Ring Size...15 (Japanese size) Stone...Pearl Stone...Diamond
