Harrods Diamond Jubilee window display crowns, designed by Lanvin, Valentino, Roberto Cavalli and Paul Smith are now up for auction.

The crowns were commissioned for Harrods’ Diamond Jubilee window displays earlier in the year. Each designer put their own unique spin on their design.

At Lanvin, Alber Elbaz lent his token flamboyance to his embellished and bejewelled crown, while likewise, Roberto Cavalli opted for crystal studding.

Valentino kept things elegant with just a touch of sparkle, while designer Paul Smith went for the fun approach: covering his with memorabilia from the last 60 years.

The auction opens for bids from today until 5 August. Winning bidders will be notified by the 8th August 2012. To enter your bid please email crownauction@harrods.com.

Bidding starts at £50. All the proceeds from the auction will go to Macmillan Cancer Support (Check out the full gallery on Facebook).
