This summer is about to get a little hotter. French jewellery house Chopard has turned up the thermostat by casting supermodel Petra Němcová as their latest muse. Radiant and sensual, Němcová is a smouldering vision decked out in the house's intricate gemstone creations.

"Petra was an obvious choice," Co-president and artistic director of Chopard, Caroline Scheufele says. "Her natural sparkle, her smile and her gentleness, combined with a generous and radiant personality, light up our creations in the most beautiful possible way."

Proving that her beauty is more than skin deep, Němcová has also partnered the jewellery house for the past two years for her Happy Hearts Fund, a humanitarian association that builds schools in natural disaster-prone areas in the world. "She really is an authentic, freedom-loving person," Scheufele continues. "She's entirely in tune with the Chopard spirit."
