A collar, also known as collar of an order, is an ornate chain, often made of gold and enamel, and set with precious stones, which is worn about the neck as a symbol of membership in various chivalric orders. It is a particular form of the livery collar, the grandest form of the widespread phenomenon of livery in the Middle Ages and Early Modern Period. Orders which have several grades often reserve the collar for the highest grade (usually called the Grand Cross). The links of the chain are usually composed of symbols of the order, and the badge (also called "decoration", "cross" or "jewel") of the order normally hangs down in front. Sometimes the badge is referred to by what is depicted on it; for instance, the badge that hangs from the chain of the Order of the Garter is referred to as "the George". Supreme Order of the Most Holy Annunciation The first of the Orders of Knighthood were the military orders of crusaders who used red, green or black crosses of velvet on their mantles, to distinguish their brotherhoods. Later the members of knightly orders used rings, embroidered dragons and even garters as the symbol of their order. In the late Middle Ages the knights wore their insignia ever more prominently and medaillons, crosses and jewels in the shape of animals began to be worn on chains around the neck, known as livery collars. In the fourteenth century, Amadeus VI, Count of Savoy (1343–1383) instituted the Order of the Collar. The order was dedicated to the Blessed Virgin Mary The primary and oldest insignia of the order is its collar. It consists of a solid gold medallion of the collar, which portrays the Annunciation of the Blessed Virgin Mary by the Archangel Gabriel. The medallion is surrounded by three intertwined Savoyan knots, decorated with small crosses fleury, and in the upper center, between two of the Savoyan knots, a cluster of rays with a dove, representing the Holy Spirit, is depicted also in gold.
