English: Official Emblem of the Office of the Royal Society
The emblem consists of the Royal Crown, symbol of kingship, placed over the upright Royal Sword with the tip pointing upward. In the center of the Royal Sword is an open book inscribed with the word "pandito", signifying that Fellows of the Royal Society are armed with knowledge. Behind the Royal Sword and the book are rays representing the light of wisdom. Below is a green ribbon the ends of which curve up to reach the ear-shaped part of the Royal Crown on both sides. The color green on the ribbon is the color of the day of birth of King Prajadhipok, Rama VII, who graciously founded the Royal Society on 19 April B.E. 2469. Underneath the Royal Crown and the green ribbon are the words The Office of the Royal Society, which appear in a curved line to correspond with the green ribbon.
