I adore this collection of real Icelandic moss jewelry by product designer Hafsteinn Juliusson. The pieces are meant to speak to people in metropolitan areas craving interaction with the natural world, bringing nature to man.
His 'Growing Jewelry Store' was displayed in the Reykjavik Art Museum last spring.
Don't think I'd wear the 4 finger piece, but the single rings are gorgeous. I'd even try and keep it alive ;)
