Uncut dragonstone

An uncut dragonstone is a members-only gem used in Crafting. They require 55 Crafting to cut, granting 137.5 experience per stone. A cut dragonstone can be cut into Dragon bolt tips by using a chisel on a cut dragonstone at level 71 Fletching. Attempting to do this will bring up a message asking if the player is sure that they want to do so, as the stones are valuable.

Divination
Uncut dragonstones can be created with 58 Divination. The materials required are 5 uncut diamonds and 2 gleaming energies. However, this is not advised due to the loss of money in the transmutation.

Mage Training Arena
The dragonstones occasionally found in the Mage Training Arena minigame are different from normal dragonstones because the Mage Training Arena "dragonstones" cannot be taken outside the Enchantment room; furthermore, they provide pizazz points when any enchantment spell is used on them. Several years ago, a glitch allowed players to take the stones outside the arena and trade them with other players, which has since been fixed.
