It is the symbol on the royal standard of the reigning monarch of Cambodia, currently King Norodom Sihamoni.

A light blue shield with an Unalome Sign, the Khmer Version of the Aum Symbol, on top of the sword is placed on two ceremonial pedestalled platters (phan) and the laurel wreath superimposed on the Royal Order of Cambodia on the bottom.

The shield is placed on the white mantle with golden fringes and the golden decorations on the bottom and was surmounted by the Royal Crown with the shining diamond emanating from the rays of light at the top of the crown.
