Uncut thunderstone

An uncut thunderstone can be achieved randomly through mining in special ares in RuneScape (one of these areas is the Celestial Dungeon), but the chances of receiving the gem are extremely rare. However, the chances of receiving the gem are heavily increased if players have 110 Mining and a Celestial pickaxe. The uncut gem is untradable, so players must be lucky enough to receive it through mining. Obtaining the stone would result in the player owning most powerful gem in the game. It can be cut into a Thunderstone with a Crafting level of 115 giving 6,000 Crafting experience.
