The Diamond Lock is an unsplicable solid lock foreground block which was added on 22 August 2014. One can be obtained from double tapping (compressing) 100 World Locks in one's inventory.
The Diamond Lock was added in order to allow players to trade items which, when combined together, worth more than 200 World Locks in a single trade. Its icon in one's inventory can be double tapped again (shattered) in order to change it back into 100 World Locks.
A Blue Gem Lock can be purchased from Sales-Man for 100 Diamond Locks, which can be turned back into 100 Diamond Locks when the player double taps on its icon in their inventory.
When compressing, it will say: "You compressed 100 World Locks into a Diamond Lock!".
When shattering, it will say: You shattered a Diamond Lock into 100 World Locks!".
