Held up well so far.
I took the charm off of this to put on my dog's tag as a joke. She only has one eye, so now she has two. Four stars because you can see in the first picture the gold outline around the eye has a thin spot. This would bother me if I was putting it on my keys but since it just for my dog I don't mind too much.<br /><br />It rubs against her other tag all of the time and has held up really well so far. No discoloring yet.
Rating: 4 stars
