The Kiss Japanese Jewelry Woman's Pink Gold Ring

The Kiss Japanese Jewelry - Woman's Pink Gold Ring - Size 5.5. My ex boyfriend gave me this and I broke up with him. I do not want this anymore. He did not want this back. I only wore it for 2 weeks. This is imported from Japan. I found the link on the website. https://online.thekiss.co.jp/k-r452pg.html I have uploaded screen shots of the translation. I'm not sure what kind of metal type or the stones it is. But after converting yen into us is about $250.
