Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.

Peers wear their coronets at coronations. Otherwise, coronets are seen only in heraldic representations, atop a peer's arms. Coronets include a silver gilt chaplet and a base of ermine fur. The coronet varies with the rank of the peer. A member of the Royal Family uses a royal coronet instead of the coronet he or she would use as a peer or peeress.
