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.

The design portrays a pulse being taken, whilst the background symbolises the rays of light from the lamp that Florence Nightingale was known for carrying during her rounds to tend to the wounded troops in the Crimean War.
