This is an exquisite gold tiara encrusted with precious stones. A tiara is a type of crown that is a decorative headband worn by monarchs and others as a sign of royalty. The term originally referred to the embroidered white silk ribbon, ending in a knot and two bands of fringe, often draped over the shoulders, that encircled a king's head to signify his authority. Such ribbons were also used to crown winners in important sports games in ancient times. A metal crown was later decorated. A tiara is also a jeweled ornament in the shape of a half-crown worn by women and placed over the forehead. In some societies it can also be a crown worn on the head. The ancient Persians wore a tall and upright royal diadem. In summary, it can be said that the diadem is generally used as an emblem of royal power or dignity.
