Extremely rare but possible piercing. Using a long
curved barbell, it is possible to pierce under the
collarbone, with exit holes on either side. For reasons of
anatomy, the piercings are in the middle of each
clavicle. This is perhaps the deepest piercing presently done, and quite possibly the most dangerous, as it provides a fast track for
infection into the body. Definitely a
bragging right piercing. Photos are available through
