A rosette is a small, circular device that is typically presented with a medal. The rosettes are either worn on the medal to denote a higher rank, or for situations where wearing the medal is deemed inappropriate, such as on a suit. Rosettes are issued in nations such as Belgium, France, Italy and Japan. Rosettes are also sometimes called bowknots, due to their shape. Moreover, a large rosette is sometimes pinned onto the ribbon which suspends a medal, typically the Officer (and sometimes Grand Officer)'s badge of certain orders of chivalry. Some small lapel rosettes are worn in the same manner as lapel pins. For instance, knights of the Order of the British Empire now wear a lapel rosette bearing the order's cross in the center, whereas previously this was a purely metallic lapel pin. While a metal lapel pin mounted on a silk rosette is considered a decoration of distinction, this is not always true of a metal emblem lacking the ribbon backing. United States In the United States, the Medal of Honor is issued with a 1/2 inch light blue rosette with white stars, authorized for civilian wear as a lapel button. Previously, the Purple Heart was also presented with a purple and white rosette, but now has been replaced by a metallic lapel pin. The lapel pin is designed to be a smaller version of the rectangular service ribbon, also for use on civilian wear. Most American military medals have the ribbon bar design scaled down to the size of a lapel pin. Members of the Sons of the American Revolution wear small, blue-and-buff rosettes as lapel buttons. The colors match those of the uniform of Gen. George Washington and the Continental Army. Belgium A rosette adorns the ribbon of all national Orders of Merit (namely the Order of Leopold, the Order of the Crown, the Order of Leopold II, and the dormant Order of the African Star and Royal Order of the Lion) at the rank of Officer. Such rosette may also be worn in diminutive form on appropriate civilian dress. Ranks above that of Officer (Commander, Grand Officer and Grand Cross) may wear a rosette adorned with gold and/or silver bars (or "half-knots") on each side of the rosette on appropriate civilian dress. Such rosette also adorns ribbon bars worn on the semi-formal dress uniform. France Several of the top decorations of France, including the
