Hollywood marriages may not always last very long, but like the saying goes, a diamond is forever.

So in honor of Valentine's Day, Us Weekly narrowed down the most amazing celebrity engagement rings ever.

Her 2008 wedding to Jay-Z was a huge secret, but there's no hiding Beyonce's 18 carat flawless diamond by Lorraine Schwartz, valued at more than $5 million.

Basketball player Kris Humphries gave Kim Kardashian a massive Lorraine Schwartz ring with a 16.5-carat emerald cut center stone flanked by a pair of 2-carat trapezoids totaling 20.5 carats worth around two million dollars. Their marriage famously lasted just 72 days.

Jennifer Lopez has been presented with a total of four engagement rings, but one stands out from the rest. Ben Affleck gave her a 6.1-carat pink diamond form Harry Winston in 2002. She reportedly returned the rock when the engagement ended in 2004.
