Barbell earrings are currently one of the most popular forms of jewelry used in body piercing.http://body-jewelry-guide.com/tag/barbell-earringsThere are many types of barbells, but the main type consists of a straight, metal bar that is attached to two decorative balls or beads at each end. A curved barbell is virtually the same, only the bar is curved slightly.

Earrings are jewelry for the ears. In most places and since the 12th century, earrings have been worn predominantly on the ear lobe.http://www.merriam-webster.com/dictionary/earring<ref>However, there are many other places to wear such ornaments. The most popular places on the body to get piercings are the tongue, eyebrow, nose, septum, belly, nipples, and ears.<ref>http://body-jewelry-guide.com/tag/barbell-earringsThese sorts of piercings outside of the traditional ear piercing are known as body piercings. Piercing in all it's forms involve sterilization of the area being pierced as well as the tools used to do the piercing, clamping of the skin, piercing needles, and sometimes a cork back to stop the needle.http://ezinearticles.com/?How-Body-Piercing-Works----The-Ins-and-Outs-of-this-Cutting-Edge-Process&id=2955Once the area that you desire is pierced, the piece of jewelry can go in, and you have either an earring or a body piercing.
