Mariah Carey's HUGE Engagement Ring Rivals Beyoncé's As The Biggest Rock In Hollywood — check it out!

As we previously reported, Mariah Carey and her billionaire beau got engaged this week after only dating for under a year. Whoa!
Still, we can't entirely blame MiMi for saying "yes" to James Packer as the businessman proposed to Nick Cannon's ex with a 35 carat rock. In fact, the famed diva has been all smiles ever since she received the sparkler (above) at Eleven Madison Park on Thursday. Aww!


A rep for Mariah even confirmed to DailyMail:

"Yes, the couple were engaged tonight in New York."

That's great, but more about the ring! According to fine jeweler David Marshall, the ring could easily be worth $7.5 million. Yep, you read that correctly!
He noted:

"The stone appears to be an Emerald cut and if it is a D Flawless (the highest color grading and without flaws) it will be in the region of $5m just for the stone at cost price. I would say that the retail value of the ring could be in the region of $7.5m."

Insane! Not to mention, Mariah's rock is supposedly grander than even Beyoncé's — who knew that was possible!
Sonia Menezes, who is the Head of Brand Development at Clogau, added:

"It's a show-stopper, particularly appropriate for Mariah Carey. It reminds me of Beyonce's fabulous 18ct flawless diamond engagement ring by Lorraine Schwartz. Beyonce's ring was valued around $5m and I would estimate Mariah's ring in excess of that amount. The Emerald cut is definitely a style favored by Hollywood royalty, with similar styles being worn by Kate Hudson, Angelina Jolie, and Amal Clooney."

LOVES it! Leave it to Mariah to need the biggest engagement ring in the land.
What do YOU think of the blonde beauty's new rock?! Is it a bit over the top??
