British Monarchy: Her Royal Highness The Duchess of Sussex: Coat of Arms
As is traditional, the arms of a married woman are impaled (placed alongside) those of her husband on the shield. The left side of the shield features the arms of the Duke of Sussex. (Read more about his Coat of Arms below). The right side features a blue background, representing the Pacific Ocean, with two golden rays, representing the sunshine of California, and three quills, representing communication and the power of words. The shield is topped by the coronet of the child of the heir apparent, which features two crosses patée, four fleus-de-lys and two strawberry leaves.
The two supporters are the golden lion on the left – taken from The Duke of Sussex’s arms – and a songbird on the right, with raised wings and an open beak, representing the power of communication. Both supporters feature the coronet of the child of the heir apparent. The grass field beneath features golden poppies, the State Flower of California, and Wintersweet which grows at Kensington Palace.

The Duke’s individual arms consist of the Royal Arms, differenced by a 5-point label. The first, third and fifth point feature a red escallop, a nod to the Spencer family’s coat of arms. Surrounding the shield is the insignia of the Royal Victorian Order, of which The Duke is a Knight Commander. The shield is supported by a gold lion on the left, and white unicorn on the right, both featuring the 5-point label, and topped with the coronet of the child of the heir apparent. The whole is topped by a gold lion, with a 5-point label, standing atop another gold coronet (this is called the Crest).
