Insignia
An eight-pointed cross, the insignia of the Order, bears a representation of St. Gregory on the obverse and on the reverse the motto "Pro Deo et Principe" (For God and Prince). It is suspended from a red and gold ribbon. In ecclesiastical heraldry, laypersons awarded the rank Grand Cross display a red and gold ribbon surrounding the shield in their coat of arms, while other ranks place an appropriate ribbon below the shield.
