annulet is a small ring, it is beleived that is it derived from the links composing chain armour. It is of frequent occurrence as a charge, and generally more than one appear: the two annulets are often linked in fess, or embraced; or they may be conjunct. Three may in like manner be interlaced in triangle. When three rings are interlaced the expression gimbal rings is sometimes used, and when more, they form a chain.
The single annulet is used in the mark of cadency, assigned to the fifth son.
