'der Ohrring' and 'das Piercing' can both be jewelry worn on the body. An 'Ohrring' is worn on the ear, usually on the earlobe. A 'Piercing' is jewelry worn through a pierced area of the skin or cartilage; the word can also mean the process of piercing. The words can be confused because many earrings are worn through a pierced ear. In everyday language, however, people usually say 'Ohrring' when talking about normal ear jewelry. 'Piercing' is more suitable for jewelry on other parts of the body or in more noticeable places on the ear, for example in the cartilage.
