Crystal key chest location

The crystal key chest is the name of a treasure chest in Taverley that is famous for containing uncut dragonstones, among other things. The chest is locked and can only be opened by a crystal key. The crystal key is made up of a loop half of a key and the tooth half of a key; you can acquire the crystal key by using them with each other. The crystal key sells for more than most of the rewards, making it more monetarily satisfying to sell the key. When the key is used it disappears, so opening the chest is a gamble. Some times the chest will award more than one of these rewards, so you can end up with multiple amounts of the reward.

Attempting to open the chest without the crystal key yields the message: "This chest is securely locked shut."

Contents and value analysis

The chest loot always includes an uncut dragonstone and will normally include another random reward, but not always. Below are the values of the chest's contents, based on current Grand Exchange prices. Players have a 9 out of 16 chance to make a profit, or a 56.25% chance, however this can fluctuate due to the price of the crystal key (other times there may be a 70% chance of a loss). A ring of wealth now increases your chances of getting a better drop since it got updated. The frequencies below are based on a batch of 3,354 keys. It is only possible to obtain rune platelegs if you are a male character, and a rune plateskirt if you are female character. It is a common misconception that you can obtain a crystal shield or a crystal bow from the chest. The chest does not contain either of these items, as they are a quest reward.

Based on the above table, the average profit from opening the chest is: Male player: Script error. Female player: Script error (prices can differ due to price differences between plateskirts and platelegs). It is not advised to try and make a profit buying keys and opening the chest because of the rare odds of some of the highest gains (such as double dragonstones).


  • The crystal key chest was reworked on 11 June 2013 with the release of the Triskelion Treasures. Previous old drops such as recieving 2000 coins and a Spinach roll along with an Uncut dragonstone was removed, and new ones were added. Charms were also added into the chest.
    • With the same update, there is a very rare chance of receiving a part of the Dragonstone armour.
