Brantley Gilbert  jana kramer ring

Brantley Gilbert put a ring on it earlier this week when he popped the question to Jana Kramer, and she said “yes.” Well, now we know just how big of a sparkler he slid on her tiny fingers.

“I’m in love with it,” Kramer tells PEOPLE exclusively. “I can’t stop looking at it!”

The five carat round stone is surrounded by diamonds set in white gold. Brantley did good.
