In heraldry, the annulet, or small ring, is a symbol of fidelity, continuity, eternity, and noble distinction, owing to its unbroken circular form. It often represents loyalty and lasting commitment, making it especially appropriate for families who wished to emphasize constancy, alliance, or enduring bonds. The annulet can also carry meanings of inheritance and status, and in some heraldic traditions it has been used as a mark of cadency, particularly to identify the fifth son.

Because rings have long been associated with honour, marriage, and pledges, the annulet brings both personal and dynastic symbolism to a coat of arms. It appears widely in British and European heraldry, sometimes as a simple charge on the shield and sometimes in groups that create strong decorative patterns. In heraldic design, its clarity and balance make it especially versatile, while its symbolism gives it depth far beyond its modest form. The annulet remains one of heraldry’s most elegant geometric charges, expressing permanence, faithfulness, and the idea that identity and legacy continue unbroken across generations.
