Mae Yokoyama, a Masters Jewelery design student at the Konstfack University of Arts, Crafts and Design in Sweden offers you the Lux solar panel collar.

Finished with solar panels, the Lux is a necklace for women that collects energy from the sun during daytime to lighten the LED bulbs, giving an appearance of glittering pearls in the dark.

Not only is this a fashion statement, it also raises the awareness of energy conservation to others.
