Angelina Jolie's wedding ring mystery solved
So why the gold band? Turns out that since Jolie, a U.N. ambassador, was leaving for a trip to developing countries Congo and Rwanda with U.K. Foreign Secretary William Hague, she did not want to be wearing any ostentatious clothing or jewelry in the poor region.
According to Grazia magazine ( via the Daily Mail), Pitt gave Jolie his great-grandmother's wedding ring so that she would still have something to wear and not have to take her engagement ring with her.
A source says, "Brad said he completely understood why she couldn't wear her engagement ring, but he really wanted to give Angelina something special and more understated to wear instead."
