Carbon-offsetting rings and things.

Super concerned about your carbon foot print? There’s jewellery just for you. San Diego-based designer (known only as) Mr. Lentz has developed a line of wooden jewelry topped with a bit of grass. Sadly, it isn’t growing grass, so you aren’t actually generating fresh oxygen on your finger (though that’d be super cool), but it looks awesome. The grass has been preserved so it won’t lose its colouring and, best of all, no watering or mowing is required.
