Depicted on the coat of arms are two animals which are a gajasingha (a lion with an elephanttrunk) on the left, and a rajasingha (a royal lion), on the right. Supported by the animals are two royal five-tiered umbrellas representing the King and the Queen. In between is a royal crown with a shining diamond at its top. On a light blue field beneath the Crown are an Unalome sign (Khmer-Thai version of the Aum symbol) atop a sacred sword, which rests on two stacked phan (pedestalled platters).
The Khmer language phrase ព្រះចៅ ក្រុង កម្ពុជា on the banner beneath the royal arms translates to: Preah Chau (royal or auspicious ruler) - Krong (area, or in this case, kingdom) - Kampuchea (Cambodia): "Ruler of the Kingdom of Cambodia".
The royal arms were discontinued with the overthow of the monarchy in the Republican Era (1970–1975). They were restored for official use in 1993 with the reinstatement of the monarchy under HM Norodom Sihanouk.
