Green, poetic and original: these gorgeous rings are from the Growing Jewelry collection designed by HAF, a company based in Reykjavik founded in 2011 by industrial/interior designer Hafsteinn Juliusson. How great is this combination of gardening and jewelry! All pieces are made out of silver and contain real icelandic moss. All you need to do is watering it and trimming it once in a while and the moss should stay green up to 8-12 months. I've managed to kill cactus plants in the past, but I'm pretty confident I could take good care of my growing ring if I had one! Necklaces are also available here.
