Demi and Ashton create charity necklaces

Demi Moore and Ashton Kutcher have designed their own collection of necklaces for Valentine's Day (14.02.11).

The Hollywood couple - who married in 2005 - have worked together with renowned jeweller Jack Vartanian to create the range of necklaces in the shape of handcuffs in order to raise funds for their charity, the Demi and Ashton (DNA) Foundation.

The pair are hoping the handcuffs motif will raise awareness of child sex slavery which their non-profit organisation is battling.

The white, yellow and rose gold designs are available with black or white diamonds and will range from between $710 to $2,140 with 50 per cent of each sale going to the charity.

Demi and Ashton are currently in Brazil where the 32-year-old actor took to the catwalk for Brazilian fashion company Colcci at Sao Paulo Fashion Week last week.

The couple spent time exploring Sao Paulo while they visited, with Demi's 16-year-old daughter Tallulah accompanying them.

While there he attempted to engage the locals in some chat, taking to twitter and writing in Portuguese, asking: "Estou pronto para o Brasil. Brazil esta pronto para mim?", roughly translating as: "I am ready for Brazil. Is Brazil ready for me?"
