A gaud is a charm or trinket typically found at the end of a rosary. These could be a crucifixor other small medallion depicting a Biblical scene or saint. A spherical type of gaud called a nut was carved from boxwood or hardstone and hinged open to reveal intricate carvings of the figures of saints or Biblical scenes and could also hang from a rosary. Sometimes these hidden treasures were made of metal and elaborately enameled. An entire rosary could be composed of intricately carved nuts.
French: noix or grain de chapelet
