Part of the British Crown Jewels, the 'Girls of Great Britain and Ireland' Tiara was given to the future Queen Mary as a wedding present in 1893. The diamond tiara was purchased from Garrard, the London jeweller, by a committee organised by Lady Eve Greville. In 1947, Mary gave the tiara to her granddaughter, the future Queen Elizabeth II, as a wedding present.
The tiara was described by Leslie Field as "a diamond festoon-and-scroll design surmounted by nine large oriental pearls on diamond spikes and set on a bandeau base of alternate round and lozenge collets between two plain bands of diamonds". Queen Elizabeth II usually wears the tiara without the base or pearls.
The tiara has appeared in many portraits of Queen Elizabeth II, including those featured on English, Australian, Jamaican and Ceylonese currency.
