It looks like Mike Fisher is an expert when it comes to ice, and we aren’t referring to the hockey rink—just check out the size of the sparkler on his fiancés finger!

Carrie Underwood showed off her brand-new bling on Monday night, Dec. 21, in Ottawa while routing for her guy. Hockey fans may have been focused on the game, but we were more interested in the blinding bling on her finger—it’s almost the size of a hockey puck! Since we were dying to know more about Carrie’s mega-huge rock, we consulted some experts to get the scoop.

David Mamane, CEO of MyJewelryBox.com, says the ring is a 12-13 carat round brilliant cut in the VVS1 range ( apparently one of the best clarities of a diamond), “It’s simple, classic, elegant and traditional, for the amount of carats and type of cut, Mike Fisher definitely got her an expensive ring.”

Mamane was able to determine the carat size based on the fact that the ring was larger than her finger (15 mm in diameter).

Jay Carlile, from Martin Katz, says the ring looks like it’s definitely at least five carats: “pro athletes are all about the size.” Hmmm! lucky Carrie.

So, how much would a sparkler of this size cost? Mamane told Hollywood Life that he estimates the ring cost 1.3 million dollars!

Not too shabby, Mike!!
