University Shield
The Columbia Shield is a symbol associated with the University. Some schools and divisions of the University use their own variation on the shield. However, most use the crown, and usage of the shield is becoming rarer. It has disappeared from the Law School's website, the podium used at University public events, the Soccer team uniforms, etc.
The shield depicted below is also sometimes depicted with gold crowns, though these are variations on the original. The similarity to the Oxford shield is probably intentional, as King's College was once envisioned to be the first university in North America, in the mold of Oxford and Cambridge, and the second President of King's College, Myles Cooper, was an Oxford-educated priest.
