The Blue Gem Lock is an unsplicable solid lock foreground block which was added as part of the Stuff! update.


Blue Gem Locks are often used to store Diamond Locks in a compact fashion, as it can be shattered back into 100 Diamond Locks when its inventory icon is double-tapped.


  • Locking a world with the lock will give the player the "Big Showoff" Achievement, granting the player 5,000 Gems. It was later changed to be given to a random new player, rather than the owner of the lock. 
  • A duplication glitch occurred shortly after release, allowing players to duplicate the lock when purchasing items from a Vending Machine.
