my computer is actually in the shop right now. and i dont think it will let you change anything after the bidding has started. i am not sure about that 100%
there is some kind of marking on the inside but i can not make out what it says. I don't have the best eyes in the world. It has not turned my finger green and i am allergic to anything not sterling silver or gold. I have not had any allergic reaction but i am not a jeweler so i can not say for sure. It is a very beautiful ring, one i would not normally give up but i do love this site!
