When I stumbled across these I instantly thought, what a beautiful detailed bracelet? However on closer inspection (and reading the description!) they are actually engraved recycled tyre's.... yes those rubber things you find on your car wheels!! They are created by Wim Delvoye. He has spent most of his art career transforming unused objects into items of beauty! These tyre's are part of a series called 'Pneu" which is french for tyre! The artist has carved intricate patterns into the tyre's surface to create different textures.
However one does wonder, where you would put a piece like this?
