The custom of decorating the head with jewelled ornaments was probably suggested by the natural idea of encircling it with flowers in token of joy or triumph. The use of diadems was in early times generally reserved for those of noble birth. From the fillets employed for binding the hair, developed circlets, which with the addition of precious stones assumed the dignity of crowns. The use of earrings as personal ornaments seems to have originated in the East, where they have always been in favour. Earrings formed an important article of jewellery during the classical ages, but they were not commonly worn again in Europe until the seventeenth and eighteenth centuries. At the present moment fashion does not decree their general use. The necklace--one of the most primitive of ornaments--is worn either close round the throat, loosely round the neck, or low down upon the breast. Occasionally, as among savage peoples, it takes the form of a ring; but as a rule it is formed either of a simple cord, or a chain formed by the appropriate linking together of rings, perforated discs, or pierced balls. Artistic effects are produced by a regular alternation of these details, as well as by the tapering of the chain from the middle towards the ends. Neck-chains with symbolic elements are those worn as orders and as signs of dignity. The necklace may be further ornamented by a row of pendants, or more generally a single pendent ornament. The pendant thus employed has become, perhaps, the most beautiful of all articles of adornment. It occupies a conspicuous position upon the person, and possibly for this reason has evoked the greatest skill and refinement of the jeweller's art. Its varieties are manifold--from the primitive charm, and the symbolic ornaments of the Middle Ages, to the elaborate pendant, for the most part purely decorative, dating from Renaissance times. Next comes the important group of ornaments worn chiefly on the breast, comprising brooches, clasps and pins, employed for fastening the dress. All have their origin in the simple pin. To this class belongs the hair-pin, of which the most handsome and varied examples are to be found in ancient work. Unlike modern hair-pins which are provided with two points, they have a single cylindrical or slightly conical stem, pointed at one end, and terminated at the other with a knob or some other finial.
