Grace Kelly ($4.06 million)
Legendary actress Grace Kelly got a breathtakingly exquisite ring from Prince Rainier. He picked it out at Cartier, and it is still valued at more than $4 million. The large diamond could easily be the main attraction of any outfit she wore. Grace Kelly had a pretty “normal” childhood, although she was raised in a wealthy family and her uncle, George Kelly, was a playwright. Kelly rose to fame in the 1950s and starred in films such as To Catch a Thief
and Dial M for Murder
. Before she got to the big screen, she moved to New York from her native Philadelphia and worked as a model and on Broadway.
