After One Month here it is!
I ordered 2 of these rings a month ago.  I wanted to wear them for a bit before reviewing.  So far my finger has not turned green and at this point I know they won't if they haven't already.  I shower, do the dishes and never take the rings off.  The lettering is still black like it was when I received the rings.  I love them and I'm so happy to have my sons names on my finger.  My only teeny tiny complaint is the lettering is small.  But I know what they say and I'm ok with that.  Happy with my purchase.
