The most expensive celebrity engagement rings

Jeff Bezos proposed to Lauren Sánchez with a massive sparkler worth an estimated US$2.5 million

24/05/23 | StarsInsider

CELEBRITY Romance

Engagement rings are an investment that sets the tone for a relationship as it moves into its next phase of life—one of either sparkling success or deep, deep debt. The four “Cs” in analyzing diamond rings are: cut, clarity, color, and carat. But there's a fifth, extremely important "C:" cost!

Jeff Bezos decided to propose to Lauren Sánchez after dating for nearly five years, but the Amazon founder certainly made her wait worth it with a massive sparkler estimated to be 20 carats and worth an eye-watering $2.5 million, Page Six reports. The happy engaged couple flashed the ring while out in Cannes before hopping back on Bezos' $500 million yacht, to put things in perspective.

But that still doesn't top the most expensive celebrity engagement ring. Check out this gallery to see which celebrities were offered the most exorbitant sparklers in exchange for everlasting(ish) love.
