That’s not just any sparkly diamond!

Turns out the huge center stone engagement ring Carrie Underwood debuted Dec .21 at fiance Mike Fisher‘s Ottawa Senators game is a flawless yellow diamond designed by jeweler Johnathon Arndt for the country superstar.

“This ring is a symbol of love from Mike Fisher to Carrie Underwood,” Jonathan said in a press release, adding “warm wishes” and congratulations to the happy couple, who got engaged Dec. 20.

Mike definitely knew which jeweler to go to after he popped the big question — Carrie’s been a fan of Johnathan’s pieces for some time! Back in February at the Grammy Awards, the singer was decked out his diamond drop earrings and a diamond band on her right hand. And at the Country Music Awards in 2007 she wore Johnathan’s twin imperial jadeite and diamond butterfly pins that were worth $6 million, according to People Stylewatch.

Can’t wait to see their wedding rings!
