|A mysterious key, for a mysterious chest.|
The crystal key is used to open the crystal chest located inside a house in Taverley. It is created by combining a tooth half of a key with a loop half of a key, displaying the message "You join the two halves of the key together." The crystal key can only be used on the chest once. After it is used, it disappears. Some notable items that can be obtained from using one key are 3 rune bars, rune platelegs or a crystal key half. The chest has a 100% chance of receiving an uncut dragonstone.
Tooth and loop halves can be obtained as rewards from Barrows, the Gnome Restaurant minigame, Managing Miscellania, and random events. Wearing the ring of wealth indirectly increases the chance for halves to be dropped by monsters who have access to the rare drop table, since the ring removes most of the "nothing" drops from the table.
This key may not be used with the steel key ring, which is only for reusable keys.
