The band of this ring is 1mm at the bottom which is thin. For the money, even on sale, it's not a great bargin. Am going to send mine back and look for a smaller size that is a little more substancial for the money. The concept is pretty. I think for a small child, I'd be afraid of them catching it on something and because it's so thin, it could harm them. If you are looking for a 1st knuckle ring, which is what I was looking for; the size is too large.
