Six sexy, sustainable designs: Nunes

This jewelry may look posh, but the primary material used here could not be more pedestrian. It is mostly made from plastic mosquito screens.

The necklace, created by Brazilian jewelry designer Valeria Nunes, was selected for the fifth edition of the Plasticidades: Plástico + Design exhibition "not only for its creativity but also for the recycling of the plastic mosquito screen, the main raw material of the necklace together with silver," says expo curator Magalhães. "Nunes wants to show people that an ordinary material can be transformed into jewelry," she adds.
