The '''Diamond Key''' is a special item in ''[[Paper Mario: The Origami King]]''. It is one of the many keys picked up by [[Luigi]] on his quest for the [[Key to Peach's Castle]]. As such, it is found in possession of Luigi, who resides on [[Mushroom Island]] at the time. Originally in a chest on [[Full Moon Island]], it is replaced by a note from Luigi and the [[Mushroom Handle]]. Luigi is seen resting, satisfied, thinking he has finally found the key to [[Peach's Castle]]. However, it turns out to be a different key, used to unlock [[Diamond Island (Paper Mario: The Origami King)|Diamond Island]]. Olivia explains that it is not the key to the castle, although it does appear to be important.

Mario must now dive down in the center between [[Club Island]], [[Heart Island]], [[Spade Island]], and Full Moon Island to find the Diamond Island dome. There is a keyhole in the center. Mario must insert the key and turn it right side up. This pushes the keyhole aside, allowing them to enter and surface inside the dome.
