This is the emblem which has been chosen to define the Queen's Platinum Jubilee next year.
Created by student Edward Roberts, 19, it has a stylised crown incorporating the number 70 on a round, purple background similar to a royal seal.
The 19-year-old from Southwell, Nottinghamshire, said he was 'over the moon' at winning the competition to design a logo run by the Victoria and Albert Museum in London.
Mr Roberts, a graphic and communication design student at Leeds University, described it as 'elegant'.
A judging panel of artists and experts praised the way the emblem captures the 'continuous thread' of the Queen's 70-year reign.

Young creatives were set the challenge of summing-up the Queen's 70-year reign with their artistic skills and Mr Roberts' simple logo was chosen.
It will be used to publicise the Queen's Platinum Jubilee, which will be marked by a special, four-day, bank holiday weekend next June.
Celebrations will range from a live concert staged outside Buckingham Palace with some of the world's biggest stars, to a day at the races for the royal family.
Mr Roberts, from Southwell, Nottinghamshire, said: 'It's just an amazing feeling to win it, I couldn't believe I'd won it really.
'I thought I had achieved something by getting to the top 100 so to even win it - I was over the moon.'
The competition was run by the Victoria & Albert (V&A) museum in conjunction with Buckingham Palace and the Lord Chamberlain, Baron Parker, the most senior official in the Queen's royal household, contacted the student on Thursday to tell him he had won.
Mr Roberts added: 'I was thinking of ways I could re-create the continuity of the Queen's reign in the design and I had a eureka moment.

'I thought if I could create a continuous line that incorporates the key features of St Edward's crown that would be a really good way of representing the continuing reign of the Queen.'
He added: 'I wanted the design to also symbolise a royal seal and put it within a circle to give the impression of a royal wax seal and I think that's come across really effectively in the design.'
Paul Thompson, vice-chancellor of the Royal College of Art and a member of the judging panel, said: 'This clean graphic design takes us on a simple line journey to create the crown and the number 70, beautifully capturing the continuous thread of Her Majesty The Queen's 70-year reign.
'Drawn on a computer, the ingenious emblem works across all scales and the flow of the line gives us a sense of a human touch behind the digital design process.'
Mr Roberts will be invited to attend next year's Jubilee celebrations, including the live concert.
