The fifth crowned portrait of HM Queen Elizabeth II facing right, wearing the George IV State Diadem and drop earrings. It features an ‘iron age’ privy mark to the bottom of the portrait of Queen Elizabeth II, a tribute to Bruce Rushin’s contribution.

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.

A concentric design symbolically representing technological development from the Iron Age, through the Industrial Revolution and the Electronic Age to the Internet, with the inscription TWO POUNDS above the design and the date below. An oddity of the design is that it depicts nineteen interlocking gears. Because there is an odd number of them, the mechanism could not actually turn (except as a Möbius strip).

Combining tradition and technology, a latent feature has been added to the design to reveal the number ‘25’ within the central cog when it catches the light. The original twist represents the evolution of minting technology at The Royal Mint – the special high-security feature is created using state-of-the-art laser technology to achieve a sharper detail than the milling machine used in 1997.

The edge inscription taken from a letter by Isaac Newton to Robert Hooke, in which he describes how his work was built on the knowledge of those that had gone before him. "If I have seen further, it is by standing on the shoulders of giants." (Newton was Warden and later Master of the Royal Mint.)
