These earrings were created by a fan of the books and represent a winged Pegasus symbol inside a circle with Camp Half Blood text. Pegasi are winged horses. They have been known to come in a variety of colors from white, black, brown and even mixed colors (ex: brown and white). They are named after the original Pegasus and are his offspring. The most notable Pegasus in the series is Blackjack, Percy Jackson's pure black Pegasus.
