A diadem (Greek: Διάδημα, from the Greek word diadeo, meaning "to bind" or "to fasten") is a type of head ornament in the form of a crown, typically made of precious metals and stones. A diadem that does not form a complete circle is referred to as a tiara.
Head ornaments resembling diadems have been known since ancient times. A diadem is a type of crown and has been used as a symbol of male status since ancient times. In Egypt during the Old Kingdom, a golden diadem-crown known as the seshed was an attribute of pharaohs, starting with Pharaoh Sneferu.
However, the ornament first referred to specifically as a diadem appeared in ancient Greece—originally as a priestly headband. Researchers believe that ancient Greek diadems symbolized the transition of a person into the realm of the dead. Another predecessor of the modern diadem is the laurel wreath. In ancient Greece and Rome, the wreath, a symbol of glory and triumph, could be made of gold.
