Before 1961 the Council had used the arms of the Diocese of Durham because the Council could be said to have succeeded, in some measure, to the palatinate jurisdiction formerly enjoyed by the palatine Bishops of Durham. In order to stress this succession the lions were depicted in the arms as grasping swords and wearing on their heads coronets used by the bishops in conjunction with the mitre. As a further mark of difference the cross was charged with five black diamonds, which are generally used to represent coal and the industries dependent upon it.
