This is used for building stuff in a Player-Owned House, such as a fireplace. It's also used for building temples in Shades of Mort'ton. You can mine it, or buy it from the Stone Mason in Keldagrim.

Rune Essence
Tired of buying runes for such high prices? Well, upon completion of the Rune Mysteries Quest, you can talk to Sedridor in the Wizards Tower, Aubury in Varrock, Cromperty in Ardougne, Brimstail in the Gnome Stronghold, and someone in the Mage's Guild (66 Magic required) to go to the Rune Essence Mine! Once there, you can go back to the person you teleported from by use of a portal. If your mining level is 1-29 or you are not on a members-only world, you can mine the standard RUNE ESSENCE. This can be used to make Air, Mind, Water, Earth, Fire, and Body runes. They CANNOT be used on members' servers to make any other runes other than those six types! If you are on a Members Server AND have 30 mining, you can mine Pure Essence. It can be used for RuneCraft and traded on ALL the servers, but only can be mined on members servers. You can make ANY rune with it (except for Blood and Soul runes, cause they aren't out yet) and it sells better then standard Rune Essence. Each Essence gives 5 Mining XP. If you get the "Lost and found" Random Event, instead of recieving Law Runes, you get 9 noted essence. Ess is short for Essence in "Runescapeese."

Pure Essence
This type of essence is used for members to make the other higher level types of runes. You need to be a member and have 30 mining to be able to get it. The street price for it is about 100gp each.
