In the context of heraldry, it is a common mistake to use the term "crest" to describe an entire coat of arms. In reality, these two components are distinct parts of an armorial achievement.
- The Crest: This is a specific device placed on top of a warrior's helmet. It is traditionally secured to the helmet by a "wreath of the colors"—a twisted band of cloth—or sometimes a coronet or cap of maintenance. Historically, crests were made of leather or light wood for use in tournaments.12
- The Coat of Arms: This refers to the principal system of hereditary symbols, typically displayed on a shield (or escutcheon). While a coat of arms can exist independently, a crest is almost always part of a larger heraldic display.12
The complete display, known as an armorial achievement, includes the shield, helmet, mantling, wreath, and crest, and may also feature additional elements like mottoes or supporters.32
