Ceremonial globe carried by a monarch (3)
I believe the answer is:
orb
'ceremonial globe carried by a monarch' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for orb that I've seen before include "Sovereign artefact" , "A poetic eye, bro" , "Spherical symbol of monarch's power" , "Jewelled ornament" , "Spherical object or shape" .)
