This is a Kiri girasol quartz ring purchased from a limited-time shop at Matsuya, directly connected to Tokyo Station (Matsuya Tokyo Marunouchi). I saw the Instagram post and fell in love with the lacy ring setting and the emotional bi-color stone of pale blue and white, so I rushed to Tokyo Station. It has a K10 stamp, and the gold is neither white nor yellow, perhaps due to the gold alloy. I'm sorry, I forgot to measure the size again, so I'll add it when I get home. I think it's about size 12. Kiri's work is characterized by the settings that hold the stones, and I find myself smiling and admiring them even when I take them off. As an aside, I lost a large pearl earring from Kiri at the beginning of the year, and I contacted various railway companies and other places I could think of, but it was never found, and I still haven't recovered from the heartbreak. I don't have to worry about that with a ring. For someone who will love to wear it. There is no particular damage, but please be aware that this is a personal item stored at home.
