Luke Bryan gifted wife Caroline a diamond ring that would be large enough to hide the sun if she held it to the sky (and it wasn't translucent).

The ring-o-saurus was a 10-year-anniversary gift back in December, but Caroline was spotted wearing it on Wednesday night (Oct. 19) during the 2017 CMA Artists of the Year event in Nashville.

People got the scoop on the ring. "It was a little 10-year anniversary gift," Bryan says. "Ten years with me feels like a thousand ... It was certainly the least I could do!”

Bryan and Caroline Boyer married on Dec. 8, 2006. The couple have two sons together, but have also been raising his brother-in-law's kids since his death in late 2014.

Bryan was one of the CMT Artists of the Year recognized in 2017. He's also up for the CMA Entertainer of the Year at the 2017 CMA Awards on Nov. 8. The "Light It Up" singer will perform at the CMAs as well, although it's not clear which song he'll sing. His next studio album, What Makes You Country, drops on Dec. 8.
