Cheryl designs rings for luxury jewellers

Cheryl Cole has designed a collection of rings for jewellery firm De Grisogono.

The stunning singer has created her own range Promise, named after her new single 'Promise This', for the luxury European jewellers.

The busy star - who is also a judge on UK reality television show 'The X Factor' - has been spotted on several occasions wearing a selection of charms by the Geneva-based business.

This is not Cheryl's first collaboration with the high-end company.

Earlier this year, the 'Fight for This Love' hitmaker received £250,000 for a 30-minute performance at a Cannes dinner and party hosted by De Grisogono.

She is also believed to have received several trinkets as a "thank you" for appearing at the lavish event, which took place at the Hotel du Cap, in front of guests including supermodel Naomi Campbell and designer Margerita Missoni.

Cheryl has previously spoken about her wish to branch out into design, saying she would love to work on her own clothing range but only when she can find the time to do it all herself.

She said: "I would love to make my own clothing range, but if I did ever do it I would like to put the time and effort in properly and do the whole thing myself.

"It would probably be a high street collection - I would take inspiration from designer stuff, but turn it into high street. But not right now."
