My daughter knew that I wanted this ring, however the only size available was a 12. I normally wear a 9.5 on my pointer finger so the size 12 is pretty big on me. I wanted, so much, for it to work that I tried wearing it with different ring spacers that can be affixed inside the ring. They worked, but I needed two and did not like how two made the ring stand out from my finger. I found that I can stack a smaller ring in front of it and it works better that way. I would still prefer to buy one the correct size if I can sell this one. It is in perfect condition and comes with the original Gucci box, charger and documents. The last picture shows the two rings stacked together.
