In the first and fourth is a crowned mermaid sounding a conch in gold against a blue background, referencing Navasse’s patron goddess, La Sirène. In the second and third are three gold shells (escallops) arranged in fess, representing the three main territories of Navasse, with gold crowns surmounting each against a red background. The royal dynastic shield surmounted by the Crown of Navasse, supported by two Sula Sula - red-footed booby, the national animal of Navasse - perched on rocks with crowns on their necks. The ocean is shown with a banner reading ‘Vires Sapientiae Virtus’ (Strength Wisdom Virtue). The shield is surrounded by the sash of the Most Royal & Illustrious Order of La Sirène, Navasse’s highest order of chivalry.
The monarch and the state use the Royal Coat of Arms as arms of dominion. Selected purveyors to the royal court can also display the royal insignia. Members of the royal family use the Medium Coat of Arms (without the supporters and banner).
