Swiss luxury jewelry and watch brand Piaget has tapped Actress Jessica Alba to be an ambassador for its new Possession jewelry collection.

Alba features in six ads for Piaget’s Possession line, which were styled by Brad Goreski and shot by Patrick Demarchelier before being released on Facebook.

The star says that she likes the “chic and simple” design of the jewelry as well as the idea of layering the gold, silver, and rose gold pieces on top of each other.

The star is on a roll: following gigs for Gucci’s kids range, Gillette, and L’Oréal, the entertainer and owner of her own fashion brand is starring in new TOUS Jewelry ads.

Using chopsticks, umbrellas, and fans as props, Jennifer Lopez was shot by star photographer Ellen von Unwerth for the Spanish brand’s oriental-inspired campaign.

The visuals echo the spring/summer collection that consists of Indian rubies and mother-of-pearl arranged in lotus flower shapes.

It has been lent to the museum by leading US diamond manufacturer Cora International for display to visitors for a limited time.

The Mad Men star models Vivienne Westwood‘s “Get a Life” Palladium jewelry collection in new visuals released March 2.

Hendricks, who has previously starred in raincoat label London Fog’s ads, said of the collection: “I love that there are dramatic pieces such as the crown and the heart necklace as well as more simple pieces such as the acorn earrings.”

“As Palladium is a naturally white metal, the pieces really sparkle under the lights and I cannot wait to wear them on the red carpet!”
