This ring really is very cool.  Totally smooth, you can't feel the edges at all.  He loves the black and loves having an unusual wedding ring.  I must say...it does look good. I like the 8 mm size on guys. This is a heavy ring, which I really like. It is getting tiny scratches in it, but they are not very noticible unless you are really looking.  At this price, I think if he wears the ring out, I'll just order him a new one.
 I highly recommend it.
