The rook piercing goes vertically through the lower leg of the antihelix, above the tragus and just back from the forward helix. While this piercing is usually done with a curved barbell for the initial healing, a ring can be worn in the piercing as well. As with other ear cartilage piercings, healing is six months or longer. While many people want to get matching piercings in each ear, it's strongly recommended that you only pierce one ear at a time. You need one ear to sleep on, use to talk on the phone, etc., and getting cartilage pierced in both ears at the same time can be incredibly difficult to heal.
