London, Nov 17 (IANS): Singer-turned-designer Victoria Beckham has put her wedding tiara up for auction.

The 39-year-old is selling her lavish 25,000 pounds gold and black crown, which she wore at her royal-themed wedding to former soccer star David Beckham on July 4, 1999, reports femalefirst.co.uk.

The 18-carat crown-style latticed tiara with diamond drops will be auctioned off at Bonhams on Dec 5 with a price of between 18,000 pounds and 25,000 pounds.

Emily Barber, director of Bonhams Jewellery Department in London, said: "Interest in the tiara is expected to be two-fold because it is designed by acclaimed jeweller, Slim Barrett, whose pieces rarely come up for sale at auction."

"The fact that it was worn by international style icon Victoria Beckham on her wedding day adds even further interest to the piece, bringing it to the attention of a wider audience."

Victoria borrowed the crown from Slim and it has since been exhibited at the Victoria and Albert Museum, but could now go to a private owner.

Victoria and David got married at Luttrellstown Castle in Ireland and the couple's four-month old son Brooklyn was the ring bearer.

To complement her crown, Victoria wore a 60,000 pounds wedding gown by Vera Wang and the couple sat in matching gold thrones.

The couple have four children together, Brooklyn, now 14, Romeo, 11, Cruz, eight, and two-year-old daughter Harper.

The family has bought a luxury 50 million pounds home near Kensington Palace, which is close to the residence of Prince William and Duchess Catherine.
