The "Medal" is round in gold, silver and bronze versions, with a suspension in the form of a royal crown with two pendelia and a ribbon ring. The obverse shows a finely ribbed central area with bead surround, with a star superimposed. The surrounding circlet carries the motto of the order: "Travail et Progrès" (work and progress) - 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.
