Can anyone identify this symbol?

I have a symbol hung around my neck on a black cord and I have no idea what it means. I think it is either Japanese or Chinese, I don’t have a digital camera so the best I can give in terms of a description is something like:

    3-o

There is a straight(ish) line above the symbol aswell that I can’t figure out how to draw using text. So, does anybody know what it means?

It is the Aum/Om symbol used in Hingu/Buddhist religion.

From hindunet:

I hope it isn’t as that was going to be my guess and I’d hate to think I was beaten to it. :smiley:

Yep, that’s the fella, thanks :slight_smile:
