Thank you. No it is not new but I tend to take good care of things. It is aproximately 1 1/4" in width. It is a good sized pendant and is fairly heavy which is why you would need a good sturdy chain to put it on. Maybe a box chain, thats what I used when I wore it :)
No they are not marked, I did not get it here in the USA. I am pretty sure it is sterling but I could be wrong. I don't want to mis represent anything and thank you for bringing it to my attention. I did try to change the listing but it would not allow me to do so.
