The red jewel is obtained from Kharshai after completing his miniquest. The red jewel can be obtained with 90 Strength by attempting to crush the jewel. Players may continue to interact with the jewel to change its colour. If a player has 90 Prayer, they may search it for curses, which will turn it into a green jewel. If the player decides to try and cut the jewel, it will turn into a blue jewel.
