I was very happy with how this looked. It seemed very high quality and I gave it as a gift.
The size was right (on a guess). But after several hours, there was a green mark left behind.
I was very disappointed by this. We tried it on a second person and no mark was left. I guess it depends on how sensitive the person's skin is. I looked up sterling silver and found out it is usually a 92.5% mixture of silver with another metal, commonly copper. Well, that explains the green. She decided to keep the ring and just wear it on a necklace.
So overall, I really liked this ring but cannot totally recommend it.
