The Most Expensive Celebrity Engagement Rings

6. Jennifer Lopez’s Engagement Ring From Marc Anthony – $4 million

Even though J-Lo ended up divorcing Marc Anthony, she kept the $4 million ring. Created by Neil Lane, the engagement ring features an 8.5-carat blue diamond. While the singer and actress still claims she’s just Jenny From the Block, if she ever sold her ring, she could buy quite a nice chunk of that block.
