Third crowned portrait of HM Queen Elizabeth II facing right, wearing the George IV State Diadem.

The George IV State Diadem, officially the Diamond Diadem, is a type of crown that was made in 1820 for King George IV. The diadem is worn by queens and queens consort in procession to coronations and State Openings of Parliament. The piece of jewellery has been featured in paintings and on stamps and currency. It can be seen in the Queen's Gallery at Buckingham Palace.

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

From 1985 to 1991 the head of Queen Elizabeth II was a slightly smaller size. From 1993 to 1997 the head was a slightly larger size. The change over was made part way through 1992 so there are two versions in this year. 1997 has small varieties in design of the portrait.

The coin’s edge inscription is in Latin ‘DECUS ET TUTAMEN’ which may be translated as an ‘ornament to safeguard’. This inscription refers to itself, as it is decorative and protects the coin from being easily counterfeited.
