a personal ornament worn pendent from the ear, usually suspended by means of a ring or hook passing through a pierced hole in the lobe of the ear or, in modern times, often by means of a screwed clip on the lobe. The impulse to decorate or to modify the appearance of the ear seems to be almost universal. In general, usage appears to call for wearing earrings in pairs, the two ornaments in all respects resembling each other; but a single earring has sometimes been worn. (The single earring was especially popular in Europe during the Renaissance and Baroque period.)
