On Monday, Buckingham Palace revealed the new Cypher of Queen Consort Camilla.
Professor Ewan Clayton designed it and it combined Camilla's initial "C" and "R" for Regina which means queen in Latin.
It will be featured by Camilla on personal letterheads, cards and gifts.
Buckingham Palace added that the new cypher will be used on the Queen Consort's cross which will be placed at the Field of Remembrance on Thursday at Westminster Abbey.
In September, the palace unveiled the new cypher of King Charles III which was personally chosen by him, from several designs presented by the College of Arms.
King Charles's cypher will be used by all Royal institutions, government departments, postcards, and mail.
