Jennifer Lopez ($4 million)

It’s no secret that actor, singer, dancer, producer and businesswoman Jennifer Lopez, has been married several times. She also had some high-profile relationships with Sean Combs and Ben Affleck, to name a few. Lopez and Affleck were also engaged for a time, and Ben gave her a pretty impressive pink diamond ring before their relationship ended. When Jennifer got engaged to singer and actor Marc Anthony, he picked out a beautiful Neil Lane ring for her that was 8.5 carats. The ring definitely doesn’t have a traditional look to it, since it features lots of blue diamonds. Looks like Anthony has some great taste in jewelry. Even though Jennifer and Marc are now divorced, Lopez still has the $4 million ring, which is likely one of the most prized pieces in her collection.
