This is absolutely not a Halloween prank.
Carlee Leifkes's boyfriend Lucas Unger proposed to her with a band adorned with his wisdom tooth in place of a diamond. And she loves it.
The couple met at a music festival earlier this year in Canada, where Lucas is from, and are now based in Carlee's native California.
Carlee announced their engagement and showcased her new bling in a post on Facebook, admitting they are not a "traditional couple."
Carlee tells Buzzfeed that she sees plenty of diamond engagement rings posted on the site: “It’s almost a contest of who has the biggest ring and whose fiancé loves them the most,” she says “And here I am with the coolest ring I’ve ever seen in my life!”
“What does a diamond signify in anybody’s relationship? I literally have my husband’s wisdom on my finger.”
She adds: “When we’d spoken about it, I’d said that diamonds are so overrated. My birthstone is a diamond. I don’t need one to prove how much someone loves me. He’d already moved all the way from Canada to do that!”
Lucas says he had the tooth removed as a child and his dad posted it to him so that he could have it set at the jeweller's.
