The magic stone mine is a special mine that can be accessed during the Tears of Guthix quest. It is located in the Tears of Guthix cavern. This mine is the only place where magic stones can be mined. Talk to Juna and she will tell the player about the story of the light creatures. Players must have started Tears of Guthix and have a sapphire lantern with them to access the stones. After the quest, the mine is still accessible, and larger rock can be mined to create ornate bowl.

As in the quest, the mine is accessed by going to the point north-west of Juna where light creatures come to the edge of the chasm, and using the sapphire lantern on one of them.
