Meek Mill reportedly popped the question with a 15-carat yellow heart diamond, which Nicki proudly showed off on Instagram, sending the Barbz into a congratulatory frenzy.
Although it's pretty impressive, if Nicki's bling is, indeed, of the matrimonial variety, it's just another in a long list of celebrity engagement rings that are big, bold and absolutely beautiful. Still, where does her (alleged) engagement ring rank? Here are nine pieces of jewelry that make us think that size really does matter.
Beyoncé: 18 CaratsGetty Images
Nothing but the best for a queen, Jay Z popped the question back in 2007 with this massive 18-carat ring. It supposedly cost $5 million, but hey, they can afford it.
Mariah Carey: 17 Carats
Nick Cannon and Mariah Carey may have split in 2014, but she certainly sported a gorgeous ring during their four-year run. The emerald-cut pink center diamond reportedly costs $2.5 million.
Angelina Jolie: 16 CaratsWireImage
After seven years together -- and seven children -- Brad Pitt popped the question to Angelina Jolie with an emerald-cut, multi-stone ring, which he helped design.
Kim Kardashian: 15 Carats
Kanye West was very hands-on with jeweler Lorraine Schwartz in designing this gorgeous 15-carat rock. And if that wasn't enough, Kanye also rented out a baseball stadium, hired a 50-piece orchestra and brought in all of Kim's friends and family to watch him get down on one knee and propose.
Ciara: 15 Carats
Future popped the question to Ciara back in 2013 with a 15-carat, emerald-cut sparkler on her 28th birthday. Ciara and Future later called it quits, only three months after she gave birth to baby Future.
Nicki Minaj (?): 15 Carats
Meek Mill may or may not have popped the question with this giant 15-carat yellow heart-shaped stunner -- which reportedly would retail for approximately $500,000 -- but if he did, then I applaud him because this is everything.
Avril Lavinge: 14 Carats
After just several months of dating (basically in secret), Nickelback's Chad Kroeger popped the question to Avril Lavigne with a gigantic platinum-set, pear-shape diamond with half moons. I mean, how could you ever say no to that?
Hilary Duff: 14 Carats
While they may be the friendliest of exes now, during their marriage, Hilary rocked her estimated $1 million engagement ring from ex Mike Comrie. The ring is simply gorgeous, and trust me, I know -- I saw it in person and almost couldn't concentrate because I was blinded by its beauty.
Lady Gaga: 6 Carats
Another star sporting the heart-shaped diamond is Lady Gaga, who has proudly shown off her ring since her fiance Taylor Kinney popped the question back in August. While it may not be as large as the other diamonds on this list, the quality of the stone is nothing but the best. No, seriously, it's pretty much flawless. Oh, and Taylor had their initials engraved into the diamond band, so props for not only giving her a gorgeous ring, but making it personal as well.
