Those aren't pearly whites sparkling when U.S. swimmer Ryan Lochte breaks out a smile. They're diamonds.
Lochte popped in his grillz -- diamond-studded mouth jewelry -- for the victory ceremony after winning a gold medal in the 400-meter individual medley.
And Lochte is hoping to win some more medals to go with his precious stones.
"This is my year," Lochte said. "I know it and I feel it, because I've put in hard work. I've trained my butt off for four years ... and there's no better way to start this Olympics off than getting gold."
