The Urim and Thummim (or seer stones) were ancinetly given to specific prophets. The borther of Jared had one, Moroni had one (or two?) and so did Joseph Smith. We're promised one according to D&C 130:10 if we're righteous. The question I have is: when. Is it after this life? Could it be during this life.

I personally believe that the prophet has one, and maybe the entire first presidency and quorum of the twelve? After all they have the title of seers. I think Ammon implies in Mosiah 18:13 that the title of seer means that they have the stone.

It's an important thing.
