The 50 most expensive celebrity engagement rings ever

Kanye knocked his engagement to Kim Kardashian out of the park in presentation alone (of course he rented out a stadium and decked it out with an orchestra and candles), but the 15-carat, $8 million ring definitely sealed the deal.

Leave it to Queen Bey to have one of the world's most expensive rings. Estimated to cost a cool $5 million, Jay-Z popped the question with an insanely gorgeous, 18-carat emerald-cut ring.

Ah, Paris and Paris. Four months after Latsis proposed to Hilton with a 25-carat, $4.7 million rock, the couple went their separate ways.

Post-Ben Affleck, J.Lo received an 8.5-carat, blue-diamond ring from Marc Anthony. While the $4.1 million ring lead the two down the aisle, the couple split up in 2014.

Prince Rainier III of Monaco popped the question with a beautiful, 10.47-carat Cartier rock. The emerald-cut diamond cost Rainier an estimated $4.06 million, but a catch like Kelley is pretty damn priceless.

Although Vanessa and Kobe have been together since 2001, Bryant upgraded her ring two years later with an 8-carat, $4 million diamond.

Aristotle Onassis proposed to Jacqueline Kennedy with what was the most expensive engagement ring of all time in 1968. The massive, 40-carat marquise-cut diamond was named the Lesotho III diamond, worth $2.6 million.

Although smaller than the ring Carey received from James Packer, Nick Cannon gave the singer a beautiful 10-carat, emerald-cut, pink diamond worth a solid $2.5 million.

Honestly, Ryan Reynolds could have proposed to Blake Lively with a plastic ring and we would have been obsessed. But, Reynolds opted for a 12-carat, oval-cut diamond for $2.5 million.

Enrique Iglesias and Anna Kournikova are pretty low-key about their relationship, but that's probably because Kournikova's $2.5 million, 11-carat engagement ring speaks for itself.

Topping Ciara's prior engagement ring from Future, Russell Wilson popped the question with a 16-carat, $2 million rock.

Although their marriage lasted for a total of 72 days, Kris Humphries bought Kim a 16.2-carat diamond for $2 million, which he later auctioned off.

As both a proposal and a birthday gift, Future gave Ciara a $1.5 million, 15-carat, emerald-cut ring.

In their hay day, Tom Cruise proposed to Katie Holmes with a beautiful, 5-carat ring that cost upwards of $1.5 million.

Ben Affleck proposed to Jennifer Lopez with a $1.2 million, 4.5-carat pink diamond that was so damn pretty, the world was genuinely taken aback when Affleck called off the wedding.
