The Crystal chest can be found in the house directly south of the witch's house in Taverley. The chest is locked and can only be opened using a crystal key, which is made by combining a loop half of key and a tooth half of key. Attempting to open the chest without the crystal key yields the message: This chest is securely locked shut. Opening the crystal chest grants an uncut dragonstone and possibly a variety of other rewards.

Opening the crystal chest is a task for the medium Falador Diary.
