Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara.

The Girls of Great Britain and Ireland tiara was a wedding present in 1947 from her grandmother, Queen Mary, who received it as a gift from the Girls of Great Britain and Ireland in 1893 on the occasion of her marriage to the Duke of York, later George V. Made by E. Wolfe & Co., it was purchased from Garrard & Co. by a committee organised by Lady Eve Greville. In 1914, Mary adapted the tiara to take 13 diamonds in place of the large oriental pearls surmounting the tiara. At first, Elizabeth wore the tiara without its base and pearls but the base was reattached in 1969. The Girls of Great Britain and Ireland Tiara is one of Elizabeth's most recognisable pieces of jewellery due to its widespread use on British banknotes and coinage.

ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSATRIX means Elizabeth II, by the grace of God, Queen and Defender of the Faith.

Depicts the heraldic shield of the Royal Arms used on the well-known Spade Guinea of George III reverse design from the 1798 Gold Guineas. It shows a crowned shield bearing the arms of England+Scotland, France, Ireland and Hanover. The once-used Hanoverian crest included on British coinage since 1714 upon the accession of King George I – the Hanoverian reference can clearly be seen towards the lower right quarter. The Spade Guinea was nicknamed for the shape of its shield that so resembled the humble garden tool.
