The medal of the order comes in many different forms, as a slightly elongated silver or gold star surmounted by a Cambodian crown and with an image of the king's crown and coat of arms in gold on a violet blue background and surrounded by a red circle. The reverse of the medal is left rough. To promote the order if it was awarded by the French, the Cambodian crown was replaced with a European one surmounted by a small cross, and in the early years the order was even awarded without any crown.
