Helix piercing jewelry refers to any type of jewelry or earrings that adorn the upper ear cartilage after it has been pierced. The jewelry used for helix piercings includes barbells, rings, helix bars and labret studs. They come in lengths varying between 4 to 11 millimeters.
The helix is the outer part of the ear, and it's typically pierced by using a specialized hollow gauge needle. The process of perforating the helix can be very painful, although the subsequent swelling and bleeding should be of no concern. Cartilage piercing normally takes a long time to heal, usually between 2 to 6 months. It is recommended to clean the site of perforation two times a day.
