PET:cell / Deco

Growing up, UK jeweller Tonya O'Hara used to watch her dad repair the broken components of TV sets. She thinks this led to her life-long "fascination with the meticulous and methodical arranging of components" — which now manifests itself as PET:cell, her line of recycled plastic bottle jewellery. Shown above are her "Tarantula," "Quill" (both with feathers), and green "Apple" rings.

Bonus link: does your idea of "PET" lean more toward bunnies than toward polyethylene terephthalate? If so, check out Japan's Deco for lots of rabbits (and squirrels).
