We often see gorgeous stars dripping in diamonds and they aren’t always theirs. Even stars can’t afford some of the jewelry they wear, so they borrow it. In the O.C. at the Bowers Museum Van Cleef and Arpels showed off Jewelry worn by Elizabeth Taylor, Princess Grace, Eva Mendes and Jennifer Garner. In attendance and talking to us were Krysten Ritter, AnnaLynne McCord, Camilla Belle and Eva Amurri.
