Insignia
The collar of the Order is in gold, with five enamelled and crowned monograms "O" (for "Oscar", the royal cipher of Oscar I, the Order's founder), five enamelled and crowned coat-of-arms of Norway, and 10 gold crosses bottony each flanked by two battle axes with silver blades and golden shafts (The latter element is also featured in the coat of arms of the Church of Norway).
The badge of the Order is a white enamelled Maltese Cross, in silver for the knight class and in gilt of the higher classes; crowned monograms "O" (for "Oscar") appear between the arms of the cross. The obverse central disc is red with the golden Norwegian lion rampart bearing a battle axe; the reverse disc bears the King Olav's motto «Ret og Sandhed» - "Justice and Truth" in Norwegian; both discs are surrounded by a white-blue-white ring. The cross is topped by a crown; military awards have crossed swords between the crown and the cross.
The star of the Order for the Grand Cross is an eight-pointed silver star with faceted rays, bearing the obverse of the badge of the Order (minus the crown on the top).
The star for Commander with Star is a silver faceted Maltese Cross, with gilt crowned monograms "O" (for "Oscar") between the arms of the cross. The central disc is red with the golden Norwegian lion rampart bearing a battle axe, surrounded by a white-blue-white ring.
The ribbon of the Order is red with white-blue-white edge stripes.
In very exceptional circumstances the Order may awarded 'with diamonds', in which case a ring of diamonds replace the white-blue-white enamel ring surrounding the central disc on the front of the badge.
