The British royal family celebrates several birthdays each August: the Princess Royal, the Duchess of Sussex, Princess Beatrice of York, the Duke of Gloucester, and Lady Amelia Windsor. But one of the most famous royal August birthdays of all belonged to Queen Elizabeth the Queen Mother, who was born on August 4, 1900. Today, we’re celebrating the Queen Mum’s birth month with a survey of her sparkling royal tiaras, worn during a remarkable life in which she held the titles of Duchess of York, Queen Elizabeth of the United Kingdom, and Queen Elizabeth the Queen Mother.
