Meghan was born and raised in Los Angeles and the statement said the blue background of the shield on her arms represented the Pacific Ocean off California's coast while two golden rays were symbolic of the state's sunshine.
The blending of Meghan's past and future is represented on the shield by the presence of both poppies, California's state flower, and wintersweet, which grows at Kensington Palace, where Meghan and Harry live.
The three quills represent communication and the power of words - no doubt a nod to Meghan's former lifestyle blog, The Tig, and her activism on gender equality and poverty.
Meghan worked with the College of Arms in London to come up with design, which was later approved by the Queen.
This may all seem rather traditional, but in gifting Meghan with her very own crest is a major break with royal tradition, People reports. It is customary for wives of members of the Royal Family to have their coat of arms feature one of their husband's supporters and one relating to themselves. It is composed of two crosses patée, four fleurs-de-lys and two strawberry leaves.
He said: "The Duchess of Sussex took a great interest in the design".
Eventually, Meghan's coat of arms will be combined with Prince Harry's for a conjugal coat of arms.
The left half of the shield features the quartered British Royal Arms.
The coat of arms is typically given to the father of the bride ahead of a royal wedding.
The arms of a married woman are shown placed side by side with her husband's in the same shield.
In 2011 a coat of arms was designed for the family of the Duchess of Cambridge - then Kate Middleton - which featured white chevronels symbolising mountains representing the family's love of the Lake District and skiing.
