The Conch is the large area of cartilage that makes up the back of the ear.
Though large diameter Ball Closure Rings have been successfully used, this piercing heals quicker when a labret or barbell is used.
Again, the gauge can be anything up to 3.2mm but the length need only be a couple of millimetres larger than the thickness of the cartilage; usually 8mm long is suitable.
Healing Time: 8 - 16 weeks
Ear cartilage piercings generally take longer to heal than lobe piercings.
This is often due to a combination of things, such as the location of the piercing in the cartilage, the type of jewellery used and the tension that jewellery creates to the structure of the cartilage.
Using biocompatible plastics (like PTFE), cleaning cartilage regularly, and increasing your intake of minerals will certainly benefit your piercing; however a piercing will almost always be doomed to failure if improper jewellery and poor planning are used and left unmonitored.
