The blue background of the shield represents the Pacific Ocean off the California coast, while the two golden rays across the shield are symbolic of the sunshine of The Duchess’s home state. The three quills represent communication and the power of words.
Beneath the shield on the grass sits a collection of golden poppies, California’s state flower, and wintersweet, which grows at Kensington Palace.
It is customary for Supporters of the shield to be assigned to Members of the Royal Family, and for wives of Members of the Royal Family to have one of their husband’s Supporters and one relating to themselves. The Supporter relating to The Duchess of Sussex is a songbird with wings elevated as if flying and an open beak, which with the quill represents the power of communication.
A Coronet has also been assigned to The Duchess of Sussex. It is the Coronet laid down by a Royal Warrant of 1917 for the sons and daughters of the Heir Apparent. It is composed of two crosses patée, four fleurs-de-lys and two strawberry leaves.
The arms of a married woman are shown with those of her husband and the technical term is that they are impaled, meaning placed side by side in the same shield.
Personally, I want to know why the songbird is being choked by its own crown. What does that symbolism mean? So many ways to interpret it.
