This is OPI Is That Silva? - which is a magnetic polish from the Skyfall collection. (The other polish in this picture is Trailer Trash, which has already been discussed.)
four years ago, and this wasn't a really widely-distributed polish at the time, either. (I didn't see it on Amazon just now when I looked.)
Here's an entry where I was talking about the polish and how I applied it. This is the entry where the picture originally was, although I don't talk much more about it there, really.
