This is an authentic GUCCI ring. It's 18K gold, k18YG (AU750), size 9. (It's a foreign size, so it seems a bit larger than a standard size 9.) It's the average ring size for a woman's ring finger. It might also fit a slender person's index finger. I was told that the material allows for resizing. It's in good condition with few scratches. It is definitely authentic. The box and sales certificate will be shipped together. This design is rare and doesn't seem to be widely available. Men could use it as a pinky ring. A vertical design of the same design was 230,000 yen on the official website. It's perfect for birthday or Christmas presents!
