The crowns above the coat of arms are also included as rank crowns. Well-decorated coats of arms still have foreign currency above or below the shield. These are slogans that often reflect the mental attitude of the owner. The official badges and medals are also counted among the gems. The hats in the church official heraldry (e.g. prelate hat , bishop's hat ) are also part of it. In the case of blazon (description of the coat of arms) these splendid pieces must be described in a special order in the heraldic terminology if they are available.
