The eastern or antique crown has a gold rim with eight sharp, triangular rays, only five of which are seen. It is given to British subjects who have distinguished themselves in service in the East and it is also often born by merchants, the association being that they are like the magi. Towns where these merchants had had a long-standing trade also often adopted eastern crowns into their arms.
The celestial crown closely resembles an eastern crown, having eight sharp, triangular rays, only five of which are seen, with the addition of a five-pointed star on each ray. It was an ornament that frequently represented the achievements of deceased ladies and it was also often given to people or institutions connected with the church.
The crown is an emblem of victory, sovereignty, and empire. It is a visible sign of success, thus the term "crowning achievement," and its significance as the decoration of the ultimate level of rank and power, makes bearing the crown a great honour. Crowns are sometimes a symbol of God, as he is considered by some to be the “King of all.” The word crown blazoned without any additional details usually implies a ducal coronet without a cap.
A crown palisado is the name of a crown with palisades on the rim forming the spikes of the crown. This can either look like the pickets of a fence, or less correctly, like the silhouette of small houses side by side with every other one upside down, with the roof of each upside down one cut out of the metal. The latter description is called a champagne border. It is said that Roman Generals awarded the crown palisado to the one who entered the camp of the enemy first after breaking through their outworks. It is also called a crown vallary from the Latin vallus, which roughly translates to palisade.
The royal or imperial crown is an emblem of empire and sovereignty. It has a studded rim with alternating crosses and fleurs-de-lis, and it is capped, with four bands of metal meeting in the center at a small cross, mounted on a ball. The imperial crown may also refer particularly to the crown of the German Emperor, though, which is very unique and only appears in a few crests.
The mural crown is plain gold circlet of battlements on a narrow rim. It is supposed to have been given by the Romans to the soldier that first mounted the breach in the walls of a town or fortress. It would also apply to the defender of a fortress or be an appropriate token of civic honour.
The naval crown is gold and uniquely ornamented with alternating topsails and sterns of ancient galleys. This was legendarily awarded to the one who first boarded the enemy’s ship and now it is awarded, in arms, to distinguished naval commanders. Some heralds say that the Emperor Claudius invented it as a reward for service at sea.
