Insignia
The badge of the order is a white enamel Rupert cross with a perimeter channel of blue enamel, with the angles in-filled with filigree back to back letter "C"s for "Congo". The central disc depicts the crowned Belgian lion on a blue enamel background surrounded by a silver ring with the motto of the Congo Travail et Progrès. This again is surrounded by a scalloped channel of blue enamel. Reverse, similar to the obverse but with a central disc of red enamel with the crowned royal monogram "L/S/L" superimposed. Suspension is by means of a pivoting royal crown and ring. The plaque—for Grand Cross—is a faceted silver eight-pointed star, or—for Grand Officer—a faceted silver Maltese Cross with silver rays between the arms. The central disc is the same to that of the badge. The medal is round in gold, silver and bronze versions, with a suspension in the form of a royal crown with two pendilia and a ribbon ring. The obverse shows a finely ribbed central area with bead surround, with a royal lion superimposed. The surrounding circlet carries the motto of the Belgian Congo: Travail et Progrès – the later issues are bilingual including the Dutch Arbeid en Vooruitgang in the lower half of the circlet. The reverse is a stylised 'double L' crowned Leopold II monogram within a palm wreath. The ribbon of the order is amaranth purple, with narrow pale yellow edge stripes bordered with pale blue. When awarded in war time, the ribbon of the Order may be adorned with a silver or gold palm. The ribbon bar of the order is worn on the semi-formal dress uniform.

Award conditions
The Royal Order of the Lion was awarded for services to Congo and its ruler that did not deserve the award of the Order of the African Star and were not necessarily performed from within the Congo. In particular, it was awarded for long distinguished service in the Belgian Congo. As with the Order of the African Star, the Royal Order of the Lion is currently administered by the FPS Foreign Affairs, but was originally administered by the Ministry of the Colonies.
