So I'm guessing you're suggesting a new kind of chest that spawns in the middle of the desert. When you open it, it contains diamonds and other items, but when you open your inventory after looting the chest, all of the looted items are gone.
What purpose would this serve? This is effectively the game trolling players. There's no reason for it to exist, and by the time I've already discovered one of these Tricked Chests, I'll start ignoring the rest of them.
