The cap badge of the Irish Guards and the bearskin plume are both based on the star and sky-blue sash colour of the Most Illustrious Order of St Patrick.
The Princess Royal is pictured presenting the Regiment with shamrock.

The centre is surrounded by a circle which bears the legend QUIS SEPARABIT ~ who shall separate ~ and the Roman numerals MDCCLXXXIII ~1783 ~ the year that the Order of St Patrick was established.
