Kate Middleton and Prince William have a new coat of arms. The Palace unveiled the new Conjugal Coat of Arms for the Duke and Duchess of Cambridge today to represent them in heraldic terms as a married couple. On the left is William's Royal Coat of Arms, which was granted to him by Queen Elizabeth II on his 18th birthday. The shield includes royal emblems for various parts of the United Kingdom, including three lions, the lion of Scotland, and a harp for Ireland. It is surrounded by a garter that reads "Shame to those who think evil of it."
On the right side is the Middleton family Coat of Arms, which was granted to Kate's family in 2011 ahead of the couple's marriage. It is technically described as a Per pale Azure and Gules a Chevron Or cotised Argent between three Acorns slipped and leaved Or. Her shield is surrounded by a garter of oak to balance out William's blue garter, which is typical for someone who is not themselves entitled to surround their Arms with an order of chivalry.
