Angelina may be wearing a diamond pendant constantly now but it isn't the first time she has worn one.
The pendant she wore a few years ago is what is called pear shape. What she is wearing now appears to be round cut.
It is likely that both pendants were gifts. From Brad.
What she is constantly wearing now is apparently very special and meaningful to her because she has hardly gone out without it. Second in frequency only to her engagement ring.
