The Most Expensive Celebrity Engagement Rings

8. Jacqueline Kennedy’s Engagement Ring From Aristotle Onassis – $2.6 million

While Paris Hilton complained that her ring was so big that it hurt her finger, Jacqueline Onassis also received a stunning diamond ring from a Greek shipping magnate, but was a lot more gracious about it. In fact, she only wore the engagement ring twice, keeping it secure in a bank vault. That’s understandable since her Lesotho III diamond ring features a 40.42-carat centerpiece, and it’s valued at $2.6 million.
