The Duchess of Cambridge’s Oak Leaf Acorn Brooch is reported to be a gift but its origin remains a mystery. The diamond brooch represents the Middleton family’s coat of arms and features three acorns on an oak leaf stem representing the three Middleton children – Catherine, Phillipa and James. The Duchess was seen wearing the brooch in 2012 during the Diamond Jubilee celebrations for the first time.
Oak trees are a symbol of Catherine’s childhood. Berkshire where The Duchess’ family lives is surrounded by the Oak trees. The current home of the Middleton family is named ‘The Oak Manor’. Her old family home was named ‘Oak Acre’.
