 The magical necklace, referred to simply as the Necklace of Harmonia, allowed any woman wearing it to remain eternally young and beautiful.It thus became a much-coveted object amongst women of the House of Thebes in Greek myths.Although no solid description of the Necklace exists, it is usually described in ancient Greek passages as being of beautifully wrought gold, in the shape of two serpents whose open mouths formed a clasp, and inlaid with various jewels.
