Leading WA jeweller Linneys will no longer be using Perth actress Jessica Marais as its brand ambassador.

Linneys secured Marais in 2010 when she was a hot property on Seven's Packed to the Rafters.

For two years, Marais, along with Jason Dundas, has given the brand a fresh youthful approach.

But Linneys has now decided on a change of direction for its next campaign, to be launched in November.

Alan Linney, Linneys creative director, said: "2012 will see Linneys move in a new direction with an exciting and very different campaign.

"Jessica and Jason remain friends of Linneys, as do our previous ambassadors, Melissa George and Ernie Dingo."
