The Brooch of Luristan was a symmetrical brooch; its color was an opalescent turquoise. During a Separatist Council gathering on the planet Geonosis in 22 BBY, Passel Argente, who was a Magistrate of the Corporate Alliance, had this brooch concealed within the crocheted folds of his hood.
Star Wars: The Visual Encyclopedia first identified the prop in 2017; the Brooch of Luristan initially appeared in the 2002 prequel trilogy movie, Star Wars: Episode II Attack of the Clones.
