Earring
From Memory Alpha, the free Star Trek reference
An earring is a piece of jewelry worn on the ear. In some cultures, it is typically the female of the species that wears earrings, though this is not always the case. Rom claimed that no woman was complete without earrings. (DS9: "Profit and Lace")
The Bajoran culture wore single earrings (traditionally on the right ear) as a symbol of their faith. (TNG: "Ensign Ro", DS9: "Accession")
