The 40-year-old slab of marzipan and thick white icing decorated with the royal coat of arms fetched more than three times its asking price of 300 euros to 500 euros.

A slice of cake from the 1981 wedding of Prince Charles and Lady Diana Spencer sold for 1,850 euros ($2,558) at auction in Britain on Wednesday -- with a warning not to eat it. The 40-year-old slab of marzipan and thick white icing decorated with the royal coat of arms fetched more than three times its asking price of 300 euros to 500 euros. "We were amazed at the numbers of people wanting to bid on this large and unique piece of royal cake icing," said auctioneer Chris Albury, a royal memorabilia specialist at Dominic Winter Auctioneers in Cirencester, western England. "There were lots of enquiries from bidders, mostly in the UK, the USA and several countries in the Middle East," he added in an email.
