It looks like the New York Mets' Yoenis Cespedes was given this diamond necklace before the game, so no wonder he's upset with himself for wearing it during a game.
His hard slide into second base made the necklace explode and spread diamonds out over the baseball diamond.
One of his teammates is seen here picking up the diamonds, which don't appear to be small.
