This is one of the more than 200 giant eggs which have been hidden around London as part of The Fabergé Big Egg Hunt.

Launched this week, the hunt aims to raise £2 million for children’s charity Action for Children and the Asian elephant conservation charity Elephant Family as well as to set a couple of new Guinness World Records, including one for the most participants in an Easter egg hunt.

Each of the eggs have been specially designed by leading artists, architects, jewellers and designers including Mulberry, Sir Ridley Scott, Bruce Oldfield, Zaha Hadid, and Zandra Rhodes.

Those participating in the hunt have the chance to win the £100,000 Diamond Jubilee Egg which has been crafted from 500 grams of rose gold and features 60 gemstones – one for each year of the Queen’s reign.

Simply locate the unique SMS keyword located on each egg and text it to 80001 to enter (you’ll be entered in the prize draw each time you SMS through a different egg keywords – it costs £3 to enter the hunt plus 25p for each egg collected plus usual phone costs).

There will also be the chance to bid online and at auction for the hand-crafted eggs along with an exclusively designed, stunning 127ct emerald, a gold egg pendant ‘Le Collier Plume d’Or’ created by Fabergé, and a chocolate egg designed by William Curley.

It is hoped the auction of the latter will set another new Guinness World Record, this time for the world’s most expensive non-jewelled chocolate egg sold at auction – both world record attempts are part of World Record London, which involves attempting more than 20 Guinness World Records.

Members of the public are also invited to take part in The Fabergé Big Egg Hunt Photo Competition, held in conjunction with the World Photography Organisation, with the best photographs to go on display at Somerset House within the prestigious Sony World Photography Awards Exhibition from the 27th April to 20th May.
