Badge of Office
The Queen issued her Royal Licence and Authority for the Shrievalty Association of England and Wales to incorporate the Royal Crown in its arms and badge in 1991. There are only a few institutions which have been licensed to use the Royal Crown in this way and so this is indeed a very rare privilege.
The swords are in saltire (crossed in an x-shape), with the blunt sword representing Mercy and the sharp sword, Justice. The Tudor roses symbolise England and the crossed leeks, Wales. The wreath of gold oak leaves is representative of the national tree of England.
The official blazon of the badge is: “Two swords in saltire Argent hilts pommels and quillons Or that in bend couped at the point charged upon an Oval Azure environed by a Wreath composed of Oak Leaves Gold with in chief and in base a Tudor Rose Gules upon Argent barbed and seeded proper and in the flanks two Leeks in saltire also proper the whole ensigned by the Royal Crown proper.”
High Sheriffs can also use their own personal arms during their term of office.
