Congratulations to Avril Lavigne and Chad Kroeger on celebrating one year of marriage, and congratulations to you if your eyes don't fall out of your head after seeing the jaw-dropping anniversary present the Nickelback singer gifted his wife.

Taking to Twitter last night (July 31), Lavigne unveiled the whopper of a diamond that Kroeger presented her on their one-year wedding anniversary, proudly showing off the 17-carat (!!!) diamond ring as she cuddled with her husband in the sweet pic.

"I still can't believe my 1 year anniversary gift. 17 carat emerald cut. Wow. I love my hubby," she wrote.

Lavigne's brand-new sparkler boasts three more carats than her engagement ring, which is, oh, just a mere 14-carat, pear shaped diamond. (To put her new ring in perspective, Kim Kardashian's engagement ring from Kanye West is 15 carats, while her ring from Kris Humphries was 20.) That is some serious, serious bling.

Check out Avril Lavigne's eye-popping diamond ring in the photo above -- and be prepared: It might literally take your breath away.
